Frequently asked questions

How is the savings interest rate calculated?

Divide the ending balance by the starting balance, raise to one over the years and subtract one. Growing $10,000 to $12,000 over 3 years implies about 6.27% a year.

Is this the rate my bank quotes?

It is the effective compound rate your balance actually earned, which already includes any compounding. A quoted nominal rate can differ slightly depending on how often interest is added.
