Frequently asked questions

How is a money market account different from savings?

A money market account often pays a higher yield and may offer limited checks or a debit card, but it can require a higher minimum balance than a basic savings account.

Is the money market rate fixed?

Usually not, the yield is variable and can change with the market, so the projection assumes the rate you enter stays constant.
