Our clients send some great questions our way, which often should be shared.  We received a good one recently which I had to consider myself when saving with Betterment:

I was wondering if I could get some advice pertaining to the timing of making deposits. For example, I was considering contributing $200 a month or$50 a week to my account. Obviously it will equal out to be the same amount but would that effect my outcome of ROE? Just a thought. Thanks for your input.

Back when I was setting up my accounts, I had to think about this as well, and came to the conclusion that the best way (for me, at least) was to deposit as soon as I could after being paid. Let me take you though my reasoning.
