Understanding the difference between APR (Annual Percentage Rate) and APY (Annual Percentage Yield) is essential for anyone engaging with crypto financial products like staking, lending, or yield farming. While both metrics express annualized returns or costs, they account for interest in fundamentally different ways. This guide breaks down what APR and APY mean, how they are calculated, and how to apply this knowledge in the context of cryptocurrency investments.
What Is APR (Annual Percentage Rate)?
APR, or Annual Percentage Rate, represents the simple interest rate applied to an investment or loan over one year. It does not take compounding into account. APR is expressed as a percentage and helps investors or borrowers understand the basic annual cost or earnings without the effect of interest being reinvested.
APR is commonly used across financial products beyond crypto, such as mortgages, credit cards, and savings accounts. For instance, a savings account offering a 3% annual rate is effectively using an APR model.
How Is APR Calculated?
APR is calculated by multiplying the periodic interest rate by the number of periods in a year:
APR = Periodic Interest Rate × Number of Periods in a Year
Depending on how interest is applied, the calculation can vary:
- Annual interest rate: APR = Annual Rate
- Semiannual interest rate: APR = Semiannual Rate × 2
- Quarterly interest rate: APR = Quarterly Rate × 4
- Monthly interest rate: APR = Monthly Rate × 12
To determine the final amount of an investment after one year using APR, use this formula:
Final Amount After One Year = Initial Amount × (1 + APR)
What Is APY (Annual Percentage Yield)?
APY, or Annual Percentage Yield, reflects the effective annual rate of return assuming that interest is compounded. Compounding means that earned interest is added to the principal amount, and future interest calculations include both the initial sum and accumulated interest. This results in exponential growth over time.
APY is especially relevant in crypto contexts like staking and liquidity pool investments, where returns are frequently compounded.
How Is APY Calculated?
APY incorporates the effect of compounding based on how often interest is applied. The formula is:
APY = (1 + Periodic Interest Rate)^Number of Periods – 1
For example, if you earn 1% interest per month compounded monthly, the APY would be calculated as:
APY = (1 + 0.01)^12 – 1 ≈ 0.1268 or 12.68%
This is higher than the straight 12% you would get with a simple APR over the same period.
APR vs APY: Key Differences
The core difference between APR and APY lies in the treatment of compounding:
- APR assumes simple interest—no compounding within the year.
- APY includes compounding, which leads to higher effective returns (or costs) over time.
Let’s illustrate with an example:
Assume you invest 1,000 USD in a crypto savings product offering a 1% monthly return.
- With APR (12%), your balance after one year would be:
$1,000 × (1 + 0.12) = $1,120 - With APY (12.68%), accounting for monthly compounding, your balance becomes:
$1,000 × (1 + 0.1268) = $1,126.80
Even with the same nominal rate, compounding results in higher earnings with APY.
How APR and APY Are Used in Crypto
Both metrics are widely used across crypto platforms and DeFi protocols:
- APR is common in lending pools and some borrowing products. For example, if you lend Ethereum in a DeFi pool offering a 10% APR, you’ll earn exactly 10% per year on your initial deposit, without compounding.
- APY is typical in staking, yield farming, and liquidity mining. Crypto exchanges and DeFi platforms often advertise APY to highlight the benefits of compounded returns. For instance, locking tokens in a staking pool with a 15% APY would yield more over time than a 15% APR product.

How to Choose Between APR and APY
Your choice depends on your goals:
- For earning returns (e.g., staking, yield farming), prefer APY-based products. Compounding maximizes growth.
- For borrowing, a lower APR is generally better, but be aware—if the loan compounds, the effective cost could be higher than the stated APR.
Always convert rates to a common basis (either APY or APR) before comparing offers from different platforms. This ensures you’re making fair comparisons.
Frequently Asked Questions
What is the main difference between APR and APY?
APR calculates simple annual interest, while APY includes the effect of compounding, which can significantly increase returns or costs over time.
Why do crypto platforms often use APY?
Many crypto-earning products like staking and liquidity pools involve frequent compounding. APY provides a more accurate measure of potential earnings in these cases.
Can APR and APY be the same?
Yes, if interest is applied only once per year and not compounded, APR and APY will be numerically equal.
Should I look for high APY or low APR?
For investments, high APY is better. For loans, low APR is preferable—but always verify if compounding applies.
How often is interest compounded in crypto products?
It varies by platform. Common compounding intervals include daily, weekly, or monthly. The more frequent the compounding, the higher the APY.
Is APY always higher than APR?
Yes, for the same nominal rate, APY is equal to or greater than APR due to compounding.
Conclusion
Understanding APR and APY empowers you to make smarter decisions in the crypto space. While APR offers simplicity, APY provides a truer picture of earnings potential through compounding. Always confirm which rate is being used, and consider using tools to convert between them for accurate comparisons. 👉 Explore advanced earning strategies in crypto
