Plain English

APY (Annual Percentage Yield) is the effective annual return on an investment, including the effect of compounding. It is the right number to compare yield products: stablecoin lending, savings accounts, staking, dividend stocks.

How it actually works

APY differs from APR (Annual Percentage Rate) in one key way: APY assumes you reinvest the interest as it accrues. If you earn 5% APR with monthly compounding, your APY is slightly higher than 5% — about 5.12%. The more often interest compounds, the bigger the gap between APR and APY. For continuously compounded rates, APY = e^APR − 1.

What it means for you

For members comparing yield products, always check whether the headline number is APY or APR — they are not the same thing. A protocol advertising “20% yield” might be quoting APR with daily compounding, which is actually about 22% APY. Conversely, some venues quote APY to make rates look better.

How ARCrypto teaches this

We teach the practical math: how to convert between APR and APY, how compounding actually changes realized returns, and the structural difference between advertised yields and what your wallet actually accrues.
