If you're new to crypto, you've probably noticed that the words APY and APR appear everywhere. But honestly, many people are still unclear about what they actually mean and why they are so important. The truth is, just understanding these two can clearly show you how much difference they make in the profits you earn from DeFi and staking.

First, let's explain APR. APR stands for annual percentage rate, representing a simple interest rate that does not consider compounding. For example, investing $1,000 in a project with a 10% APR would yield a $100 profit after one year. It's straightforward and easy to understand. However, there's a catch. Since APR does not include compounding, no additional profits are generated over time. In cryptocurrency, this is often used in lending protocols and staking rewards that do not automatically compound.

On the other hand, APY is completely different. APY stands for annual percentage yield, indicating the actual return rate that includes the effect of compounding. Even with the same 10%, if the APY is calculated daily, the story changes. Depositing $1,000 means interest earns interest, and profits accelerate throughout the year. As a result, you end up with slightly more than $100 in profit. The power of compounding is especially strong in crypto protocols that frequently calculate interest.

Why is there such a difference? APY incorporates compounding into the calculation, reflecting a more realistic return. When earning through DeFi pools or staking, you should look at APY rather than APR. This is because if compounding occurs daily or weekly, APY more accurately shows the actual earnings.

When making investment decisions, it depends on which type of product you choose. If you want higher returns through compounding, look for investments with APY. For simple interest products or loans, APR provides sufficient information. However, keep in mind that in crypto, APY rates often fluctuate based on market demand and protocol policies. It’s good to develop a habit of always checking whether the rate is fixed or variable.

In reality, many DeFi platforms offer APY on assets like ETH, BTC, and stablecoins. Some major exchanges also provide APY through their earning products. Before deciding where to deposit your assets, it’s important to understand how APY works and estimate the potential benefits of compounding. Making informed decisions based on this information can lead to long-term profits.
