Understanding the difference between APR and APY is essential for making informed financial decisions—especially in the world of cryptocurrency. While these terms are often used interchangeably, they represent distinct concepts that significantly impact borrowing costs and investment returns. Whether you're staking, lending, or saving in crypto, knowing how APR and APY work can help you maximize gains and minimize expenses.
What Is APR?
Annual Percentage Rate (APR) represents the annual cost of borrowing money or the simple annual return on an investment, without compounding. In cryptocurrency, APR is commonly used to describe interest rates for loans, staking rewards, or yield farming returns—though it only reflects the base interest rate.
For example:
- If you borrow $1,000 in crypto at a 10% APR, you’ll owe $100 in interest after one year—assuming no fees and no compounding.
- If you stake $5,000 in a DeFi protocol offering 8% APR with monthly payouts, you earn $400 annually—but only if you don’t reinvest those earnings.

Key Factors That Affect APR
Several variables influence the APR you receive:
- Creditworthiness: Traditional finance uses credit scores to determine APRs; higher scores lead to lower rates.
- Loan Type: Mortgages typically have lower APRs than credit cards or personal loans.
- Lender Policies: Different platforms offer varying APRs even for identical products.
- Loan Amount and Term: Larger or shorter-term loans may come with more favorable rates.
- Market Conditions: Rising interest rates in the broader economy often push APRs upward.
- Down Payment: A larger initial deposit can reduce your APR on secured loans.
APR vs. Interest Rate
While often confused, APR and interest rate are not the same. The interest rate is the basic cost of borrowing, while APR includes additional fees—such as origination or service charges—making it a more accurate reflection of total borrowing costs.
For instance, a crypto loan with a 5% interest rate plus a 2% platform fee results in a 7% APR.
This transparency helps borrowers compare offers fairly and avoid hidden costs.
What Is APY?
Annual Percentage Yield (APY) measures the total return on an investment over one year, including compound interest. Compounding means your earned interest is added to your principal, so future interest is calculated on a larger amount.
In crypto, compounding can occur daily, weekly, or monthly depending on the platform. The more frequent the compounding, the higher the APY compared to APR.
For example:
- Deposit $1,000 into a savings pool with 5% APY compounded monthly, and you’ll earn about $51.16 in a year—not just $50—due to compounding effects.
- Stake $10,000 at 10% APY with daily compounding, and your balance could grow to $11,051.56 after 12 months.
APY vs. Interest Rate
Unlike a simple interest rate, APY accounts for compounding, giving a truer picture of real returns. Two investments with the same nominal rate but different compounding frequencies will have different APYs.
A 10% annual rate compounded monthly yields an APY of approximately 10.47%.
Thus, APY is always equal to or greater than the stated interest rate.
APR vs. APY: Key Differences
| Feature | APR | APY |
|---|---|---|
| Definition | Simple annual return or cost | Total annual return including compounding |
| Compounding | Not included | Included |
| Best Used For | Loan costs, simple interest earnings | Investment growth, staking, yield farming |
| Calculation Basis | Simple interest formula | Compound interest formula |
| Accuracy | Understates long-term returns | Reflects actual growth potential |
| Example (Savings) | $1,000 at 10% APR = $100/year | $1,000 at 10% APY = ~$104.71/year (monthly compounding) |
| Example (Borrowing) | $1,000 loan at 12% APR = $120 interest | Same loan at 12% APY ≈ $126.83 due to compounding |

Borrower’s Perspective: Why APR Matters
When taking out a crypto loan, APR gives a baseline for expected costs. For instance:
- Borrowing $5,000 in stablecoins at 12% APR means $600 in interest over one year—assuming no compounding.
However, many DeFi platforms apply compound interest, making the actual cost closer to APY. If interest compounds monthly on that same loan, the effective cost rises to around $680—a significant difference.
Additionally:
- Variable Rates: Some crypto loans have floating APRs tied to market liquidity or asset volatility.
- Hidden Fees: Not all platforms include fees in their quoted APR, complicating comparisons.
- Reinvestment Risks: Auto-compounding features may increase returns but also exposure to smart contract risks.
Always review terms like “compounding frequency” and “effective rate” before committing.
Investor’s Perspective: Why APY Matters
For savers and investors, APY is the gold standard for measuring real growth. Crypto platforms advertise high yields through staking, liquidity provision, or yield farming—all usually expressed as APY when compounding is involved.
For example:
- Staking $10,000 at 8% APY with daily compounding earns about $832.78 in a year.
- The same rate as APR would only yield $800—highlighting the power of compounding.
When comparing opportunities:
- Prioritize platforms with higher compounding frequency (daily > monthly > annually).
- Evaluate token stability and platform reliability—high APYs often come with higher risk.
- Watch for temporary "boosted" yields that may drop after promotional periods.

Which Is Better: APR or APY?
Neither metric is inherently better—it depends on your role:
- Borrowers: Focus on APR to understand base financing costs.
- Lenders/Investors: Use APY to assess true earning potential.
In DeFi:
- Liquidity pools may advertise rewards as APR (e.g., transaction fees + token rewards).
- Auto-compounding vaults convert APR into effective APY by reinvesting earnings.
Example: A DEX liquidity pool offering 8% APR with daily reinvestment effectively delivers over 8.3% APY.
Frequently Asked Questions (FAQ)
What’s the difference between APR and APY?
APR (Annual Percentage Rate) reflects simple annual interest without compounding, used mainly for loans. APY (Annual Percentage Yield) includes compound interest and shows actual returns on savings or investments.
Is it better to earn APR or APY?
You’re better off earning APY, especially in crypto savings or staking. Since APY includes compounding, your money grows faster than with simple APR-based returns.
Can APR and APY change over time?
Yes. Both can fluctuate based on market conditions, platform policies, or whether rates are fixed or variable. Always monitor your positions and read the fine print.
How does compounding frequency affect APY?
The more frequently interest compounds (daily vs. monthly), the higher the APY. Daily compounding maximizes growth over time compared to less frequent cycles.
Why do some platforms show APR instead of APY?
Platforms may display APR to make returns appear simpler or lower—especially for loans. Investors should ask whether rewards are compounded and request APY equivalents for accurate comparisons.
How do I convert APY to APR?
To estimate APR from APY:
- Subtract 1 from APY (e.g., 5% → 1.05)
- Raise it to the inverse of compounding periods (e.g., 1/12 for monthly)
- Subtract 1 and multiply by periods per year.
Or use:
APR ≈ n × [(1 + APY)^(1/n) – 1]
Where n = number of compounding periods per year.
For 5% APY compounded monthly: ~4.88% APR.
Understanding APR vs. APY empowers smarter financial choices in both traditional and decentralized finance. Use APR to evaluate borrowing costs and APY to measure investment growth—especially where compounding accelerates returns. Always compare offers carefully and consider real-world factors like fees, risk, and market dynamics before investing.
