The pitfalls of comparing portfolio returns Jan 28, 2026 8:00:00 AM How to take stock of your stocks (and bonds)—here, there, everywhere. Investing can feel like a leap of faith. You pick a portfolio. You deposit money. Then, you wait. Trouble is, it takes a while for compound growth to do its thing. Using the Rule of 72 and historical stock returns, it takes roughly a decade for every dollar invested to double. That’s a lot of time for second-guessing. You may peek at your portfolio returns and wonder, “Could I be doing better?” Don’t worry; it’s normal to question whether we’re making the right choices with our money. But comparing different portfolios can be tricky. Variables abound. There’s the composition of the portfolios themselves, but also their fees and tax treatments. So whether you’re sizing us up with rival money managers, or with the stock indexes you see most often in the news, we’re here to help you level set. The ABCs of apples-to-apples comparisons Let’s start with a statistic we’re quite proud of: Since its launch, our Core portfolio’s average annual return has been ~10% after fees*. Those are the returns of real Betterment customers, minus fees, and taking the timing of deposits and withdrawals out of the equation. This helps focus more on the performance of the portfolio itself. *As of 12/31/2025, and inception date 9/7/2011. Composite annual time-weighted returns: 20.1% over 1 year, 9.3% over 5 years, and 10.1% over 10 years. Composite performance calculated based on the dollar-weighted average of actual client time-weighted returns for the Core portfolio at 90/10 allocation, net of fees, includes dividend reinvestment, and excludes the impact of cash flows. Performance not guaranteed, investing involves risk. So, is 10% good? Well, it depends on the comparison. Stock indexes like the S&P 500 and Dow Jones dominate the news, but they’re hardly comprehensive. For one, they exclude bonds, a lower-yield staple of many portfolios. There’s a reason why regardless of the portfolio, we recommend holding at least some bonds. They help temper market volatility and preserve precious capital. Secondly, popular indexes also largely ignore international markets. The S&P, for example, typically represents less than half the value of all investable stocks in the world. Our globally-diversified portfolios, meanwhile, spread things out in service of a smoother investing journey. We're built for the long run, and history has shown that American and International assets take turns outperforming each other every 10-15 years. So the modest amount of international exposure in many of our portfolios means this: you're in a better position to profit when the pendulum swings the other way. Now, taking all of this to heart isn't easy. Not when the S&P returns 20% in a given year. At moments like these, it’s perfectly normal to feel FOMO when looking at the returns of your globally-hedged investing. To keep the faith, it helps to keep the right benchmark(s) in mind. Not all diversification is created equal We’re not alone in offering globally-diversified portfolios. But two portfolios, even with similar stock-to-bond ratios, can take very different paths to the same end goal. Tax optimization, market timing, and fund fees can all impact your investing’s bottom line as well. Some investors compare providers by investing a little with each, waiting a few months, then comparing the balances. This sort of trialing, however, may not tell you much. When it comes to our portfolios, you can find better comparisons in two particular ETFs that seek to track a wide swath of the market: ACWI for stocks and AGG for bonds. See how your Betterment portfolio stacks up against them in the Performance section for any goal or account. Simply scroll down to “Portfolio returns,” click “Add comparison,” and pick from the available allocations of stocks and bonds. We show your “Total return” by default at Betterment, otherwise known as the portfolio’s total growth for a given time period. You can also see this expressed as an “Annualized” return, or the yearly growth rate you often see advertised with other investments. Putting your performance in perspective Comparison may be the thief of joy, but it’s okay, prudent even, to evaluate your investing returns on occasion. Once or twice a year is plenty. The key is to steer clear of common pitfalls along the way. Like comparing your globally-diversified apple to someone else’s all-U.S. orange. Or cherry-picking a small sample size instead of a longer, more-reliable track record. It’s easier said than done. That’s why we bake more relevant comparisons right into the Betterment app. It’s also why we produce content like this. Because if there’s a silver lining to the slow snowballing of compound growth, it’s that you have plenty of time to brush up on the basics.

Save more, sweat less with recurring deposits

Save more, sweat less with recurring deposits Jan 28, 2026 5:00:00 AM How one click—and the power of dollar cost averaging—can boost your returns Healthy habits like exercising, eating well, and saving are hard for a reason. They take effort, and the results aren’t always immediate. Except in the case of saving, there’s a simple hack that lowers the amount of willpower needed: setting up recurring deposits. So kick off those running shoes, because you barely have to lift a finger to start regularly putting money into the market. $2, $200, it doesn’t matter. This one deposit setting, along with a little help from something called dollar cost averaging, can lead to better returns. Our own data shows it: Betterment customers using recurring deposits earned ~4% higher annual returns. Based on Betterment’s internal calculations for the Core portfolio over 5 years. Users in the “auto-deposit on” groups earned an additional 0.6% over the last year and 1.6% annualized over 10 years. See more in disclosures. Three big reasons they fared better than those who rarely used recurring deposits include: When you set something to happen automatically, it usually happens. It's relatively easy to skip a workout or language lesson. All you need to do is … nothing. But the beauty of recurring deposits is it takes more energy to stop your saving streak than sustain it. When you regularly invest a fixed amount of money, you're doing something called dollar cost averaging, or DCA. DCA is a sneaky smart investment strategy, because you end up buying more shares when prices are low and fewer shares when prices are high. A steady drip of deposits helps keep your portfolio balanced more cost-effectively. Instead of selling overweighted assets and triggering capital gains taxes, we use recurring deposits to regularly buy the assets needed to bring your portfolio back into balance. Now it’s time for an important caveat: The benefits of dollar cost averaging don't apply if you have a chunk of money lying around that’s ripe for investing. In this scenario, slowly depositing those dollars can actually cost you, and making a lump sum deposit may very well be in your best interest. But here’s the good news: While DCA and lump sum investing are often presented in either/or terms, you can do both! In fact, many super savers do. You can budget recurring deposits into your week-to-week finances—try scheduling them a day after your paycheck arrives so you’re less likely to spend the money. Then when you find yourself with more cash than you need on hand, be it a bonus or otherwise, you can invest that lump sum. Do both, and you may like what you see when you look at your returns down the road.

Inside the investing kitchen, part 1

Inside the investing kitchen, part 1 Jun 24, 2025 11:30:00 AM The recipe for a better portfolio, and the science behind a safer nest egg. Jamie Lee isn’t a Top Chef, but he knows his way around the kitchen. He dabbles in sous vide with the help of a sous chef (his 6-year-old daughter). He loves smoking salmon low and slow on a pair of pellet grills. And in some ways, his day job on the Betterment Investing team resembles the culinary world as well. He and his teammates work in a test kitchen of sorts, defining and refining the recipes for our low-cost, high-performing, and globally-diversified portfolios. They size up ingredients, pair flavors, and thoughtfully assemble the courses of each “meal.” All in service of customers with varying appetites for risk. It's highly-technical work, but we wouldn't be Betterment if we didn't make our methodologies as accessible as possible. So whether you're kicking the tires on our services, or you're already a customer and simply curious about the mechanics of your money machine, come along for a three-part, behind-the-scenes look at how we cook up a better portfolio. Here in part 1, we'll explore how we allocate your investing at a high level. In part 2, we'll zoom in to our process for selecting specific funds. And in part 3, we'll show you how we handle thousands of trades each day to keep our customers’ portfolios in tip-top shape. The science behind a safer nest egg Betterment customers rely on Jamie and team to do the heavy lifting of portfolio construction. They distill handfuls of asset classes, a hundred-plus risk levels, and thousands of funds into a simple yet eclectic menu of investment options. And underpinning much of this process is something called Modern Portfolio Theory, a framework developed by the late American economist Harry Markowitz. The theory revolutionized how investors think about risk, and led to Markowitz winning the Nobel Prize in 1990. Diversification lies at the heart of Modern Portfolio Theory. The more of it your investing has, the theory goes, the less risk you're exposed to. But that barely scratches the surface. One of the meatiest parts of building a portfolio (and by extension, diversifying your investing) is how much weight to give each asset class, also known as asset allocation. Broadly speaking, you have stocks and bonds. But you can slice up the pie in several other ways. There’s large cap companies or less established ones. Government debt or the corporate variety. And even more relevant as of late: American markets or international. Jamie came of age in South Korea during the late 90s. Back here in the States, the dot-com bubble was still years away from popping. But in South Korea and Asia more broadly, a financial crisis was well underway. And it changed the trajectory of Jamie’s career. His interest in and application of math shifted from computer science to the study of markets, and ultimately led to a PhD in statistics. Jamie Lee (right) helps optimize the weights of asset classes in Betterment portfolios. For Jamie, the interplay of markets at a global level is fascinating. So it’s only fitting that when optimizing asset allocations for customers, Jamie and team start with the hypothetical "global market portfolio," an imaginary snapshot of all the investable assets in the world. The current value of U.S. stocks, for example, represents about two-thirds the value of all stocks, so it's weighted accordingly in the global market portfolio. These weights are the jumping off point for a key part of the portfolio construction process: projecting future returns. Reverse engineering expected returns “Past performance does not guarantee future results.” We include this type of language in all of our communications at Betterment, but for quantitative researchers, or “quants,” like Jamie, it’s more than a boilerplate. It’s why our forecasts for the expected returns of various asset classes largely aren't based on historical performance. They're forward-looking. "Past data is simply too unreliable," says Jamie. "Look at the biggest companies of the 90s; that list is completely different from today.” So to build our forecasts, commonly referred to in the investing world as Capital Market Assumptions, we pretend for a moment that the global market portfolio is the optimal one. Since we know roughly how each of those asset classes performs relative to one another, we can reverse engineer their expected returns. This robust math is represented by a deceivingly short equation—μ = λ Σ ωmarket—which you can read more about in our full portfolio construction methodology. From there, we simulate thousands of paths for the market, factoring in both our forecasts and those of large asset managers like BlackRock to find the optimal allocation for each path. Then we average those weights to land on a single recommendation. This “Monte Carlo" style of simulations is commonly used in environments filled with variables. Environments like, say, capital markets. The outputs are the asset allocation percentages (refreshed each year) that you see in the holdings portion of your portfolio details At this point in the journey, however, our Investing team's work is hardly finished. They still need to seek out some of the most cost-effective, and just plain effective, funds that give you the intended exposure to each relevant asset class. For this, we need to head out of the test kitchen and into the market. So don’t forget your tote bag.

Inside the investing kitchen, part 2

Inside the investing kitchen, part 2 Jun 24, 2025 11:25:00 AM See how we source the higher-quality, lower-cost funds that fill up your portfolio. A lot goes into the making of a single Betterment portfolio. So much that we're spreading out this showcase of our Investing team's work over three parts. In part 1, we explore how we allocate customers’ investing at a high level, and in part 3, we show how we handle thousands of trades each day to keep their portfolios humming. And here in part 2, we zoom into a topic that may be a little more relatable for the everyday investor: picking the actual investments themselves. If asset allocation is like refining a recipe, then today's topic of fund selection is all about the sourcing of higher-quality, lower-cost ingredients. And for that, we turn our eye toward a market of another kind. Josh Shrair specializes in shopping capital markets here at Betterment, picking the funds that fill up your portfolio's respective allocations. His line of work looked a little different decades ago, back when his step dad was working as a trader on Wall Street. Back then, this level of attention to portfolio construction and fund selection was typically in service of only the ultra wealthy. But now, Josh and team navigate a rapidly-expanding universe of investments on behalf of everyday investors. Why shopping for funds isn't always so simple On one hand, the recent explosion of investment options has been great for investors. Increased competition drives down costs and opens up access to newer, more niche markets. But more choice also leads to more complexity. Take Exchange Traded Funds (ETFs), our preferred building block for portfolios thanks to their transparency, tax efficiency, and lower costs. They bundle up hundreds, and sometimes thousands, of individual stocks and bonds. But even ETFs are multiplying fast. In 2024 alone, 723 new ones launched, bringing the total to nearly 4,000. To illustrate this abundance, let's say your asset allocation calls for a heaping serving of “Large Cap” stocks, meaning companies valued at $10 billion or more. Nearly 500 ETFs populate this particular corner of the ETF universe. We can narrow that group down to 30 based on the specific exposure we’re looking for, like say U.S. Large Cap companies, or the S&P 500, a list or “index” of 500 of the biggest American companies. But the due diligence is hardly done. Some ETFs that track the S&P 500 follow it faithfully, while others put their own spin on it, which can open investors up to unintended exposure. Josh Shrair (second from left) helps navigate a rapidly-expanding universe of ETFs on behalf of Betterment customers. Just as crucially, their costs are all over the place, and higher fees can erode your returns in the long run. That's why the SPDR fund is currently our Core portfolio’s primary way of achieving U.S. Large Cap stock exposure. It offers both a low cost to hold (0.02%) and a low cost to trade (0.03% at the time of writing), making for a low overall cost of ownership. "Shopping for investments is a little like buying a car," Josh says. "The total cost is way more than the sticker price." How we calculate cost of ownership Part of our role as a fiduciary, someone who's legally obligated to act in their clients' best interests, is conducting a deep and unbiased evaluation of the ETFs used in our portfolios. The process Josh and team use is entirely "open architecture," meaning we’re not obligated to use funds from any particular provider. Instead, we strive to select the most optimal ones in terms of cost and exposure. It helps that Betterment itself doesn't make, manage, and sell funds, which means we avoid the inherent conflict of interest some advisors face when they also act as a fund manager. These firms can be tempted to steer customers toward their own funds, even when a better alternative exists. So we take pride in the due diligence behind our fund selection, and that begins with our "cost of ownership" scoring methodology. It factors in the two types of costs mentioned earlier: the cost to "hold" or own a fund, also known as its expense ratio, and the cost to trade it. As you'll see in part 3 of this series, a portfolio is hardly static. Deposits come in. Withdrawals go out. Rebalancing takes place on the regular. All of this requires daily trading, so the cost of those transactions matters to your investing's bottom line. The cost-to-trade is also known as the "bid-ask spread," or the markup that traders expect when selling a share. It's how they make money, and similar to wholesalers and retailers like Costco, the bigger the fund, the smaller the margins a trader can live with. Seeking out these value buys is how we're able to deliver globally-diversified portfolios at a fraction of the cost of alternatives on the market today. And we’re never done shopping. Our preferred funds are updated multiple times throughout the year. Primed for the purchase There's a lot more to our fund selection methodology, especially for funds that aren’t tied to a specific index, but are instead made from scratch. Some fund managers like Goldman Sachs, where Josh worked earlier in his career, also blend both approaches into a “smart beta” strategy. We offer one such portfolio alongside our Betterment-built collections. But for the sake of this series, let's pretend for a moment that our tote bags are full, and we're ready to check out. It’s time to meet the team behind every transaction at Betterment.

Should you fill up your 401(k) first, or your IRA?

Should you fill up your 401(k) first, or your IRA? Oct 24, 2024 11:30:19 AM Navigating one of retirement saving’s first forks in the road. Can you have both a 401(k) and an IRA? Yes! But having access to both accounts begs the question: Which one is more deserving of your retirement dollars? The answer, as it so often does in personal finance, depends on your situation. So let’s explore when a 401(k)-first mentality makes sense, and when it doesn't, before closing things out with a wildcard third option that might warrant both your attention and your savings. A quick refresher on retirement accounts For the sake of this conversation, we're focusing on the two most common retirement accounts: the IRA and the 401(k), including the non-profit/public equivalent 403(b) account. Both come with built-in tax advantages, annual contribution limits, and eligibility criteria: 401(k) Accessible to: Anyone whose employer offers one 2025 contribution limit: $24,500 (for those under 50) IRA Accessible to: Anyone whose Modified Adjusted Gross Income (MAGI) falls below the IRS's eligibility limits (see table below) qualifies for tax benefits. 2025 contribution limit: $7,500 (for those under 50) 2026 IRA income limits Traditional IRA* Modified Adjusted Gross Income (MAGI) Roth IRA Modified Adjusted Gross Income (MAGI) Full tax deduction $0-$79,000 (single) Full contribution $0-$149,999 (single) $0-$126,000 (married) $0-$235,999 (married) Partial tax deduction $79,001-$88,999 (single) Partial contribution $150,000-$164,999 (single) $126,001-$145,999 (married) $236,000-$245,999 (married) No tax deduction** $89,000 and up (single) No contribution $165,000 and up (single) $146,000 and up (married) $246,000 and up (married) *If covered by a retirement plan at work **Anyone is eligible to make taxable contributions to a traditional IRA Source: IRS Power ranking your retirement accounts In general, there are a few reasons why you might default to the 401(k), including but not limited to: You can contribute by way of payroll deductions and ease the sting of saving. Many employers offer matching contributions, aka free money. And you can contribute significantly more money to them than IRAs. Altogether, that's a lot of pros working in the 401(k)’s favor. But not all 401(k)s are created equal. Some providers charge more for limited investment options. According to the 24th edition of the 401k Averages Book, the average investment expense for some smaller plans1 was 1.12%. By comparison, you can invest with a Betterment IRA for an all-in fee well south of 1%. So ask your employer or 401(k) provider for help sizing up your total costs. Or take a look at your 401(k) statement for code names like: Management fees Asset-based fees Operating expenses Expense ratios If you find your 401(k) costs are significantly steeper than an IRA, consider the following order of operations: Fill up your 401(k) up to your employer’s match, assuming they offer one. Max out your IRA, assuming you’re eligible. Come back to your 401(k). On the other hand, if your 401(k)’s fees are competitive, congratulations! Things just got simpler. Consider maxing it out first before turning your attention to an IRA, or that wildcard option we mentioned earlier. A quick aside on the Health Savings Account (HSA) Sure, the name says "health," but HSAs can be repurposed for retirement savings as well. They come with a $4,400 contribution limit for individuals, and they’re available to anyone enrolled in a high-deductible health plan (HDHP). They’re also triple tax-advantaged, meaning money is tax-free going in, tax-free while it grows, and tax-free coming out, assuming it’s used for qualified expenses. That’s one more tax perk than 401(k)s and IRAs, which make you choose between either tax-deferred contributions or tax-free withdrawals. Tax-free contributions Tax-free growth Tax-free withdrawals Traditional 401(k)/IRA ✓ ✓ X Roth 401(k)/IRA X ✓ ✓ HSA ✓ ✓ ✓ So if an HDHP is right for your healthcare needs, consider prioritizing an HSA before an IRA. Between those two accounts and the 401(k), that's more than $30,000 worth of annual investing potential. Fill up those tanks, and you’ll be well on your way to retiring. Now just enjoy the ride.

The savvy saving move for your excess cash

The savvy saving move for your excess cash Aug 6, 2024 2:37:52 PM And why taking the “lump sum” leap may be in your best interest We're living in strange financial times. Inflation has taken a huge bite out of our purchasing power, yet investors are sitting on record amounts of cash, the same cash that's worth 14% less than it was just three years ago. High interest rates explain a lot of it. Who wouldn't be tempted by a 5% yield for simply socking away their money? But interest rates change, and we very well could be coming out of a period of high rates, leaving some savers with lower yields and more cash than they know what to do with. So let's start there—how much cash do you really need? Then, what should you do with the excess? How much cash do you really need? Cash serves three main purposes: Paying the bills. The average American household, as an example, spends roughly $6,000 a month. Providing a safety net. Most advisors (including us) recommend keeping at least three months' worth of expenses in an emergency fund. Purchasing big-ticket items. Think vacations, cars, and homes. Your spending levels may differ, but for the typical American, that's $24,000 in cash, plus any more needed for major purchases. If you're more risk averse—and if you're reading this, you just might be—then by all means add more buffer. It's your money! Try a six-month emergency fund. If you’re a freelancer and your income fluctuates month-to-month, consider nine months. Beyond that, however, you're paying a premium for cash that’s not earmarked for any specific purpose, and the cost is two-fold. Your cash, as mentioned earlier, is very likely losing value each day thanks to inflation, even historically-normal levels of inflation. Then there's the opportunity cost. You're missing out on the potential gains of the market. And the historical difference in yields between cash and stocks is stark, to say the least. The MSCI World Index, as good a proxy for the global stock market as there is, has generated a 8.5% annual yield since 1988. High-yield savings accounts, on the other hand, even at today’s record highs, trail that by a solid three percentage points. So once you've identified your excess cash, and you’ve set your sights on putting it to better use, where do you go from there? What should you do with the excess? Say hello to lump sum deposits. Investing by way of a lump sum deposit can feel like a leap of faith. Like diving into the deep end rather than slowly wading into shallow waters. And it feels that way for a reason! All investing comes with risk. But when you have extra cash lying around and available to invest, diving in is more likely to produce better returns over the long term, even accounting for the possibility of short-term market volatility. Vanguard crunched the numbers and found that nearly three-fourths of the time, the scales tipped in favor of making a lump sum deposit vs. spreading things out over six months. The practice of regularly investing a fixed amount is called dollar cost averaging (DCA), and it’s designed for a different scenario altogether: investing your regular cash flow. DCA can help you start and sustain a savings habit, buy more shares of an investment when prices are low, and rebalance your portfolio more cost effectively. But in the meantime, if you’ve got excess cash, diving in with a lump sum deposit makes the most sense, mathematically-speaking. And remember it’s not an either-or proposition! Savvy savers employ both strategies—they dollar cost average their cash flow, and they invest lump sums as they appear. Because in the end, both serve the same goal of building long-term wealth.
