How to Convert APY / APR

01Choose directionSelect whether you are converting APR to APY or APY to APR. APR (Annual Percentage Rate) is the simple annual rate without accounting for compounding — it's the nominal rate quoted by most lending protocols. APY (Annual Percentage Yield) includes the effect of compounding interest, giving you the true annualized return. DeFi platforms often advertise APY because it sounds higher (e.g., 10% APR compounded daily = 10.515% APY), so knowing the conversion lets you compare fairly.

02Enter rateType the annual rate as a percentage — for example, enter 12 for 12%. The tool accepts decimal values for precision (e.g., 12.5). The mathematical formulas are: APY = (1 + APR/n)^n - 1 (where n = compounding periods per year), and APR = n × ((1 + APY)^(1/n) - 1). These are the standard financial formulas used by banks, DeFi protocols, and regulatory bodies worldwide.

03Set compounding frequencyChoose how often interest compounds per year: daily (365) gives the most accurate real-world result for most DeFi protocols, weekly (52) is common in traditional savings accounts, monthly (12) matches most credit card and loan calculations, quarterly (4) is used by some bond instruments, and yearly (1) provides a baseline where APR = APY. Higher frequency means more interest-on-interest accumulation, resulting in a higher APY for the same APR.

About APY ↔ APR

APR (Annual Percentage Rate) is a simple annual rate without compounding — it represents the flat interest rate over one year. APY (Annual Percentage Yield) accounts for compound interest, where earned interest is reinvested to generate additional returns. The mathematical relationship is: APY = (1 + APR/n)^n − 1, where n is the number of compounding periods per year. For example: 12% APR compounded daily (n=365) → APY = (1 + 0.12/365)^365 − 1 ≈ 12.747%. 8% APR compounded monthly (n=12) → APY = (1 + 0.08/12)^12 − 1 ≈ 8.30%. The difference grows dramatically at higher rates — 100% APR compounded daily = 171.4% APY. Continuous compounding gives the mathematical upper bound: APY = e^APR − 1.

When to use it

Use this when comparing staking, lending, or yield products across chains and platforms. Common scenarios: comparing a CEX offering 8% APR staking vs a DeFi protocol offering 8.2% APY lending, understanding the true yield of a vault advertising '15% APR with daily compounding', or converting a credit card's 24% APR to its effective APY equivalent.

Tips & Tricks

•If compounding frequency is unknown, yearly (1) gives a lower-bound APY — actual APY is always higher if compounding occurs more frequently.
•APY assumes reinvestment at each compounding interval — real yields may differ if you withdraw early or if the rate changes during the year.
•Daily compounding (365) is standard for most DeFi protocols; weekly (52) is common in traditional finance; continuous compounding gives the mathematical upper bound.
•For very high rates (>100%), the difference becomes dramatic — a protocol advertising "200% APY" might only offer 100% APR compounded daily.
•The rule of 72 gives a quick estimate: at 10% APR, money doubles in ~7.2 years; at 10% APY (with daily compounding), it doubles in ~6.9 years.
