How we worked it out

Updated as you change the numbers.

  1. Value = deposit × (1 + APY)^(months ÷ 12) = $10,000.00 × 1.0425^1.

Method and assumptions

APY is the actual yearly growth including compounding, so the value after t years is deposit × (1 + APY)^t. If you know only the stated rate and compounding, the APY is (1 + rate ÷ m)^m − 1. Early withdrawal penalties are not included.
