This CD calculator estimates how much your certificate of deposit may be worth at maturity based on your initial deposit, interest rate, term length, and compounding frequency.
It can also include optional monthly deposits, although many CDs do not allow ongoing contributions. The calculator shows total deposits, total interest earned, maturity value, and inflation-adjusted value in today’s dollars.
For a one-time deposit, the calculator uses the compound interest formula:
FV = P × (1 + r / n)nt
Where:
If monthly deposits are included, the future value of those contributions is added separately using a recurring deposit formula.
Many CDs only allow a one-time opening deposit. If your CD does not permit additional deposits, leave the monthly deposit field at zero.
CDs usually lock your money in for a fixed period. Early withdrawal may trigger a penalty, which this calculator does not include.
A CD with a higher APY may produce a better return, but compounding frequency can also slightly affect the final maturity amount.
Inflation can reduce the real purchasing power of your maturity value, which is why an inflation-adjusted result can be useful.
A certificate of deposit is a savings product that typically offers a fixed interest rate for a set term in exchange for keeping your money deposited until maturity.
Interest rate is the base annual rate, while APY reflects the effect of compounding over a year. Some banks advertise APY rather than simple annual rate.
No. This calculator estimates growth to maturity only. It does not subtract any penalties or taxes.
Some specialty products may allow it, but many standard CDs do not. Check your bank’s rules before assuming ongoing deposits are permitted.
