Frequently asked questions

Can I enter a zero interest rate?

Yes. With no interest, savings equal your starting balance plus all monthly contributions.

Can I enter APY as the annual rate?

This input is a nominal annual rate with monthly compounding. To convert APY as a decimal, use 12 × ((1 + APY)^(1/12) − 1), then multiply by 100.
