APY Calculator
See how much a savings account or CD grows at a given APY over time.
APY already includes the effect of compounding, so this uses (1 + APY)^years directly.

What Is the APY Calculator?
The APY Calculator shows the future value of a deposit in a savings account or certificate of deposit (CD) based on its annual percentage yield (APY) and term. Because APY already reflects compounding, the math is straightforward. Enter the deposit, APY and years to see the maturity value and interest earned. Runs in your browser.
How It Works
Enter your deposit amount, the account's APY and the term in years. The value at maturity and the interest earned update instantly.
When to Use It
Use it to compare high-yield savings accounts and CDs, or to project how much interest a deposit will earn.
Frequently Asked Questions
- What's the difference between APR and APY?
- APY (annual percentage yield) includes the effect of compounding, so it reflects what you actually earn in a year. APR doesn't. Savings products usually quote APY.
