CD Calculator
Calculate the interest and maturity value of a certificate of deposit from its APY and term.
A certificate of deposit locks your money up for a fixed term at a fixed rate. In return the rate is usually higher than a savings account.
Enter the APY and term to see what you will have at maturity.
How it works
The APY already includes compounding. The deposit grows at that yearly rate for the length of the term.
Terms shorter than a year earn a proportional share of the APY.
The formula
APY = annual percentage yield as a decimal.
Tips
- Compare the early withdrawal penalty before you buy. It is often three to twelve months of interest.
- Brokered CDs can be sold before maturity. Bank CDs usually cannot.
