Annual Percentage Rate (APR) is the yearly interest rate earned or paid on an investment or loan, not accounting for compounding.
Detailed Explanation
In cryptocurrency, APR represents the simple annual return you can expect from staking, lending, or providing liquidity. Unlike APY (Annual Percentage Yield), APR does not factor in compound interest. When a DeFi protocol advertises 10% APR on staking, it means you would earn roughly 10% of your staked amount over one year, with rewards distributed linearly. APR is commonly displayed on platforms like Aave, Compound, and Lido for lending and staking rates.
Why It Matters
Understanding the difference between APR and APY is crucial for evaluating DeFi yields accurately. APR understates actual returns when rewards are compounded frequently, while APY reflects the true annualized return including compounding. Many protocols display APR because it appears more conservative, while others show APY to highlight higher effective returns. Comparing investments requires using the same metric consistently.
Key Considerations
When evaluating DeFi yields, always check whether the advertised rate is APR or APY. Be cautious of extremely high APR rates as they often come from unsustainable token emissions that dilute the reward token value over time. Factor in gas costs, impermanent loss risk, and smart contract risk when calculating real returns.
Example
A user stakes 100 ETH on a platform offering 5% APR. After one year, they would earn approximately 5 ETH in rewards (assuming the rate stays constant). If the same rate were expressed as APY with daily compounding, the effective yield would be about 5.13%.

Understanding the difference between APR and APY is crucial for evaluating DeFi yields accurately.
Sustainable APR rates typically range from 3-15% for blue-chip DeFi protocols. Rates above 50% often come from new protocol emissions and tend to decrease rapidly. Stablecoin lending usually yields 2-8% APR depending on market conditions.
