CD Calculator — Certificate of Deposit Maturity Value

Calculate what a certificate of deposit pays at maturity from rate and term.

Formula

Maturity value = deposit × (1 + APY)^(months/12) — APY is the effective annual yield, so compounding is already included

Examples

$10,000 at 4.5% for 12 months$10,450.00 · $450.00 interest
$10,000 at 5% for 60 months$12,762.82 · $2,762.82 interest
$25,000 at 4% for 24 months$27,040.00 · $2,040.00 interest

Frequently Asked Questions

What is a certificate of deposit?

A savings product where you lock a fixed amount for a fixed term in exchange for a fixed interest rate. Withdrawing early usually triggers a penalty.

Should I enter APR or APY?

Enter APY if the bank advertises the annual percentage yield, which already accounts for compounding. If you only have the nominal rate, use the APY calculator first.

Does the calculator include taxes or penalties?

No. Interest is usually taxable and early withdrawal penalties are not modelled — this shows the gross maturity value.
