APY, APR, and Compounding: Reading Crypto Yields Honestly

Educational only — not financial advice. Earning yield carries real risk, including loss of your deposit. A high advertised rate is not a promise. See yield farming risks for the dangers behind the numbers.

Every earn product leads with a percentage. Learning to decode that number — what it includes, how it compounds, and whether it's even real — is the difference between an informed decision and chasing a mirage.

APR vs APY

• APR (annual percentage rate) is the simple yearly rate, without compounding.
• APYAnnual percentage yield — the yearly return on an investment, including the effect of compounding. (annual percentage yield) includes the effect of compounding — earning returns on your returns.

Because APY assumes you reinvest, it's always equal to or higher than the APR for the same product. Platforms often advertise the more flattering APY, so always check which one you're looking at when comparing.

Compounding frequency matters

How often a yield compounds changes the outcome. The same APR compounded daily produces a higher APY than compounded monthly. It's why two products quoting the "same" rate can pay differently — and why the compounding period is part of the real comparison, not a footnote.

Absurd yields are a warning, not a gift

A savings-like product paying single digits is plausible. A protocol advertising hundreds or thousands of percent is telling you something: that yield is usually paid in a freshly-printed token whose price is collapsing as fast as it's emitted, or it's an unsustainable incentive that ends abruptly. The higher the advertised yield, the harder you should scrutinize where it comes from. If no one can explain the source clearly, treat it as a red flag.

Nominal versus real

A 100% APY paid in a token that drops 90% is a loss, not a gain. The headline rate is nominal; what matters is your real return after the reward token's price change and any fees. Always ask: paid in what, and is that asset holding its value?

Key takeaways

• APR is the simple rate; APY includes compounding and is always equal or higher.
• Compounding frequency changes the real yield — daily beats monthly at the same APR.
• Sky-high advertised yields usually come from collapsing emission tokens or unsustainable incentives.
• Judge the real return after the reward token's price moves and fees, not the nominal rate.
• If no one can clearly explain where a yield comes from, treat it as a warning.
• Not financial advice — high yields carry high risk, including total loss.
