How the CD Rate Calculator Works

A certificate of deposit pays a fixed interest rate for a fixed term. Banks quote the APY — annual percentage yield — which already accounts for compounding, so your balance simply grows by the APY each year for the length of the term.

Longer terms and larger deposits usually earn more, but your money is locked in: withdrawing early typically forfeits some interest. This estimate assumes you hold the CD to maturity, and shows pre-tax figures.

value at maturity = deposit × (1 + APY)^years

Frequently Asked Questions

What is APY?

APY, or annual percentage yield, is the real rate of return after compounding is applied. Because it already includes compounding, you can multiply it across the years directly.

What happens if I withdraw early?

Most CDs charge an early-withdrawal penalty, often several months of interest. This estimate assumes you keep the CD until it matures.

Is CD interest taxable?

Yes, interest earned on a CD is generally taxable as income in the year it is credited, even if you do not withdraw it. This calculator shows pre-tax figures.
