How this estimate works
The calculator converts APY into an equivalent monthly rate: (1 + APY ÷ 100)1/12 − 1. Each month it applies that rate to the balance, then adds your contribution. At 0% APY, the result is simply your starting balance plus contributions.
For example, $1,000 with no contributions and a constant 4% APY becomes $1,040 after one year, before taxes and fees. This is a hypothetical example. Savings APYs can change; this tool does not forecast rates or account for inflation, fees, taxes or withdrawals.
