APY Calculator
Convert APR to APY accounting for compounding frequency.
🏦 APY (Annual Percentage Yield) accounts for compounding. APY > APR when compounding more than once a year.
What Is This Tool?
APY (Annual Percentage Yield) is the real return on savings accounting for compounding. APR is the simple rate; APY is what you actually earn when interest compounds more than once a year.
APR vs APY
On a 5% APR savings account: compounding monthly gives APY of 5.116%; compounding daily gives 5.127%. The more frequent the compounding, the higher the APY — and the bigger the gap between APR and APY.
The Formula
APY = (1 + APR/n)ⁿ − 1, where n is compounding periods per year. This tool computes it for any frequency.
What to Look For
- High-yield savings accounts quote APY (looks better than APR)
- Credit cards and loans quote APR (looks lower than APY)
- Always compare the same metric when shopping rates
Frequently Asked Questions
