How a CD Grows Your Money

A Certificate of Deposit locks your money away for a fixed term in exchange for a guaranteed interest rate, usually higher than a regular savings account, with interest compounding over the term.

Formula

Maturity Value = Principal × (1 + Rate ÷ n)^(n × Years), where n is the number of compounding periods per year.

Frequently Asked Questions

How is CD (Certificate of Deposit) return calculated?

It compounds your principal at the CD's fixed interest rate over the term length, based on the compounding frequency the bank uses (daily, monthly, etc.).

What happens if I withdraw early?

Most CDs charge an early withdrawal penalty (often a number of months' worth of interest), which this calculator doesn't include unless you factor it in separately.

Is CD interest taxable?

Yes, in most jurisdictions CD interest is taxable as income in the year it's earned, even if you don't withdraw it.
