Understanding the difference between Annual Percentage Yield (APY) and Annual Percentage Rate (APR) is essential for anyone navigating the world of finance—especially in cryptocurrency and decentralized finance (DeFi). These two terms are often used interchangeably, but they represent fundamentally different calculations that can significantly impact your returns or borrowing costs.
Whether you're investing in a DeFi protocol, staking crypto, or taking out a loan, knowing how APY and APR work empowers you to make smarter financial decisions. Let’s break down what each term means, how they differ, and why it matters.
What Is APY?
Annual Percentage Yield (APY) represents the total return you earn on an investment over one year, including the effect of compound interest. Unlike simple interest, compound interest allows your earnings to generate additional earnings—essentially, you earn "interest on interest."
Imagine a snowball rolling down a hill: as it rolls, it picks up more snow and grows larger. Similarly, with compounding, your investment grows faster over time because each interest payment is added to the principal before the next calculation.
For example:
- If you invest $1,000 at a 10% APY compounded annually, you’ll have $1,100 after one year.
- If that same 10% rate compounds monthly, your balance grows slightly more—approximately $1,104.71—because interest is calculated and reinvested 12 times during the year.

In the crypto space, APY is commonly used to advertise returns from staking, liquidity pools, and lending protocols. DeFi platforms may offer APYs ranging from 2% to over 20%, though these rates are typically variable and fluctuate based on market demand and asset volatility.
Because APY accounts for compounding frequency, it provides a more accurate picture of real-world returns than APR.
What Is APR?
Annual Percentage Rate (APR) refers to the simple annual interest rate charged or earned, without factoring in compounding. It’s the base rate used to calculate interest over a year.
For borrowers, APR reflects the cost of borrowing. For investors, it shows the basic return before compounding effects. Because it doesn’t include how often interest is applied, APR tends to understate the true cost or return when compounding occurs.
Example:
- A loan with a 12% APR compounded monthly results in an effective annual cost higher than 12%. In fact, the actual yield (APY) would be about 12.68%.
- Conversely, an investment advertised at 10% APR with daily compounding would have an APY of approximately 10.52%.
APR is widely used in traditional finance for products like credit cards, mortgages, and auto loans. Regulatory requirements often mandate APR disclosure so consumers can compare loan offers transparently.
In DeFi, APR is frequently shown alongside APY—especially for borrowing positions—so users understand both the base rate and the compounded outcome.
Key Differences Between APY and APR
| Feature | APY | APR |
|---|---|---|
| Includes Compounding | Yes | No |
| Best For | Investments, staking, savings | Loans, borrowing |
| Accuracy of Returns | Reflects real earnings | Shows nominal rate |
| Calculation Complexity | Higher (depends on frequency) | Simpler |
| Typical Use Case | Earning interest in DeFi | Paying interest on loans |
The most important takeaway: APY is always equal to or greater than APR for the same stated rate, assuming compounding occurs more than once per year.
Let’s illustrate this:
- A 10% APR compounded monthly equals roughly 10.47% APY
- To get a 10% APY with monthly compounding, the equivalent APR would be about 9.57%
This distinction becomes critical when comparing financial products. A platform advertising “10% returns” could mean either APR or APY—knowing which one determines whether you’re getting a good deal.
Which Is Better: 10% APY or 10% APR?
The answer depends on whether you're earning or paying interest.
If You're Investing or Lending: 10% APY Is Better
With a 10% APY, your investment earns compound interest, resulting in higher overall returns. A $1,000 deposit earns exactly $100 in one year (assuming annual compounding).
With a 10% APR (compounded monthly), the effective return drops to about 9.57% APY, meaning you’d earn only ~$95.70—less than the advertised rate.

If You're Borrowing: 10% APR Is Better
As a borrower, you want to minimize interest paid. A 10% APR means you pay less over time compared to a 10% APY loan, which includes compounding charges.
That’s why:
- Savings accounts and DeFi yields advertise APY (higher number = more attractive)
- Loans and credit cards advertise APR (lower number = appears cheaper)
Always check whether the rate quoted is APY or APR before committing to any financial product.
Why This Matters in Crypto and DeFi
In decentralized finance, both metrics are used across various protocols:
- Lending platforms display APY for depositors (e.g., supplying USDC to earn yield)
- Borrowers see APR as the base cost of borrowing assets
- Some dashboards show both to give full transparency
Because DeFi rates are often variable and tied to liquidity demand, understanding how compounding affects your position helps avoid surprises. High APYs may look enticing—but if they’re based on volatile tokens or unsustainable incentives, the risk might outweigh the reward.
Additionally, many yield farming strategies involve reinvesting rewards frequently (manual or auto-compounding), pushing actual returns closer to the advertised APY.
Frequently Asked Questions (FAQ)
What does APY mean in crypto?
APY stands for Annual Percentage Yield. In crypto, it measures the total return on investments like staking or lending over one year, including compound interest. It gives a realistic view of potential earnings.
Is higher APY always better?
Not necessarily. While a high APY suggests strong returns, it may come with higher risk—especially if tied to volatile tokens or new protocols. Always assess security, tokenomics, and sustainability before chasing high yields.
Can APR be lower than APY?
Yes. APR is always equal to or lower than APY when compounding occurs. For example, a 5% APR compounded monthly results in an APY of about 5.12%.
How is APY calculated?
APY is calculated using the formula: APY = (1 + r/n)^n – 1
Where:
r= annual interest rate (APR)n= number of compounding periods per year
Should I look at APR or APY for crypto loans?
For borrowing, focus on APR as it reflects the base interest cost. However, check if fees or penalties increase the effective rate beyond what APR shows.
Do all crypto platforms use APY correctly?
Not always. Some projects misleadingly label simple interest as APY to inflate perceived returns. Always verify how often compounding happens—or whether it happens at all.

Final Thoughts: Make Smarter Financial Decisions
Understanding APY vs APR isn’t just about definitions—it’s about protecting your capital and maximizing returns. Whether you're staking Ethereum, supplying liquidity on a DEX, or borrowing against your holdings, knowing how interest works gives you a competitive edge.
Remember:
- APY includes compounding → best for evaluating investment growth
- APR excludes compounding → useful for comparing borrowing costs
- Always confirm which rate is being advertised
- High yields often come with high risks
By mastering these fundamentals, you’ll be better equipped to navigate both traditional finance and the fast-moving world of crypto with confidence.
