Interest is compounded monthly and deposits are assumed at the end of each month.

The formula

Balance = P(1+r)^n + D · ((1+r)^n − 1)/r, with r = annual rate ÷ 12

Frequently asked questions

What rate should I enter?

Use the account's APY. High-yield savings accounts publish an APY that already reflects compounding.

How do I find the monthly deposit for a target amount?

Use the Savings Goal Calculator — it solves for the deposit needed to reach a specific goal by a specific date.
