How it works

Type the initial deposit in dollars. CDs typically have a minimum of $500-$1,000, with jumbo CDs requiring $100,000+. Our calculator works for any amount - it scales the interest projection to your input.
Type the annual percentage yield (APY) quoted by the bank. Add the term in months. APY already includes compounding, so do not enter the APY and also select compounding frequency. Our calculator shows the maturity value for any APY/term combination.
The result shows: total interest earned, maturity value, effective annual yield, and a year-by-year table. To compare CDs, run the calculator multiple times with different APYs and terms. The compare view lets you see 2-3 CD options side by side and see which is best for your timeline.
