When you first start in the crypto asset space, terms like APY and APR come up very frequently. But in reality, not many people truly understand the difference between these two, or why they are so important.

First, to explain what APR is, it represents the annual percentage rate, which is a simple interest rate that does not include compound interest calculations. Investing $1,000 in a project with a 10% APR would yield a $100 profit after one year—a straightforward calculation. However, here’s the catch: APR does not account for compounding, so the interest earned does not generate additional interest over time. If you see DeFi lending protocols or staking rewards that do not automatically compound, they are usually using APR.

In contrast, APY refers to the actual annual yield that includes the effects of compounding. The same 10% APY, if compounded daily, would result in slightly over $100 profit on a $1,000 investment. In the crypto world, protocols often perform compounding calculations daily or even hourly, which makes this difference quite significant. Especially for those involved in DeFi pools or staking, the numbers shown as APY more accurately reflect the actual earnings you can expect.

If someone asks about APR, it’s safe to remember that it’s a fixed interest rate without compounding. On the other hand, APY includes compounding, so your earnings grow at an accelerating rate over time. Understanding this difference can greatly influence your decision-making in crypto investments.

When depositing funds into DeFi platforms or staking crypto assets, especially when frequent compounding occurs, APY provides a more accurate picture of the actual returns. Conversely, for loans or savings that do not involve compounding, simply looking at APR is sufficient.

So, which should you choose? If you want higher returns through compounding, look for investments that offer APY. For simple interest products or loans, you can clearly understand the returns using APR.

A common question is whether APY changes over time. In the crypto world, APY rates can frequently fluctuate depending on protocol policies and market demand. Always check whether the rate is fixed or variable. Also, APY is usually higher than APR because of the effects of compounding. When compounding occurs frequently, the difference between APY and APR becomes more pronounced over time.

Many DeFi platforms and staking programs offer opportunities to earn APY with crypto assets. There are numerous protocols providing APY on assets like ETH, BTC, and stablecoins. Some major exchanges also offer APY through their Earn products.
