Understanding financial metrics is crucial when navigating the world of cryptocurrency investments. Two of the most commonly used terms—APR (Annual Percentage Rate) and APY (Annual Percentage Yield)—often appear in discussions around passive income strategies like staking and yield farming. While they may seem similar at first glance, their implications on returns are significantly different. This article breaks down APR vs. APY in crypto, explains how they work, and helps you determine which offers better returns under various scenarios.
What Is APR in Cryptocurrencies?
APR, or Annual Percentage Rate, represents a simple interest rate. It reflects the amount of interest you earn (or pay) over one year without accounting for compounding. In crypto, APR is typically used to describe the base return on investments such as staking, lending, or borrowing.
For investors, APR shows how much you’ll earn annually on your principal investment. For borrowers, it indicates the cost of taking out a loan in crypto terms.
Why APR Matters
APR is a foundational metric in decentralized finance (DeFi) and centralized platforms alike. You’ll encounter it when exploring:
- Crypto staking opportunities
- Lending protocols
- Flash loans and other borrowing mechanisms
Because APR doesn’t include compounding, it gives a straightforward view of returns. However, this simplicity can be misleading if not compared correctly with APY.

How Is APR Calculated?
The basic formula for calculating APR is:
APR = Periodic Rate × Number of Periods in a Year
For example:
- A monthly rate of 0.5% translates to an APR of 6% (0.5% × 12 months).
- A flat 6% APR on 10 BTC means you’d earn 0.6 BTC after one year—totaling 10.6 BTC.
However, real-world APR calculations may also factor in fees and additional costs:
APR = [(Fees + Interest Paid / Principal) / Days in Term] × 365 × 100
This version is more accurate for loans but less commonly displayed in DeFi dashboards.
What Is APY in Cryptocurrencies?
APY, or Annual Percentage Yield, takes compounding into account. Unlike APR, APY reflects the actual rate of return you earn when interest is reinvested over time. Because you earn interest on both the principal and previously accumulated interest, APY is almost always higher than APR under the same nominal rate.
Albert Einstein famously said:
“Compound interest is the eighth wonder of the world. He who understands it, earns it; he who doesn’t, pays it.”
In crypto, compounding can occur daily, weekly, or monthly—depending on the platform—making APY a more powerful indicator of long-term growth.
How Is APY Calculated?
The standard formula for APY is:
APY = (1 + r/n)ⁿ – 1
Where:
- r = periodic interest rate (as a decimal)
- n = number of compounding periods per year
Let’s apply this using a 6% annual rate with monthly compounding:
- r = 0.06
- n = 12
- APY = (1 + 0.06/12)¹² – 1 ≈ 6.17%
Even with the same 6% base rate, the effective return jumps due to compounding.
Here’s how frequency affects yield:
- Semi-annual compounding: ~6.09%
- Quarterly: ~6.14%
- Monthly: ~6.17%
- Weekly: ~6.18%
- Daily: ~6.18%
As shown, daily compounding maximizes returns, making APY especially attractive in high-frequency DeFi environments.

Key Differences Between APR and APY in DeFi
While both metrics express annualized returns, their application varies across DeFi strategies.
APR vs. APY in Staking
Crypto staking involves locking up tokens to support blockchain operations (e.g., via Proof-of-Stake) and earning rewards in return. Platforms may advertise either APR or APY:
- APR: Shows raw, non-compounded rewards.
- APY: Reflects compounded gains if rewards are automatically reinvested.
For example:
- A staking pool offering 12% APR with monthly payouts will yield exactly 12% per year.
- The same pool advertising 12% APY assumes monthly compounding, resulting in slightly higher actual earnings.
Always check whether rewards are compounded automatically or require manual reinvestment.
APR vs. APY in Yield Farming
Yield farming goes beyond staking by allowing users to provide liquidity to decentralized exchanges (DEXs) through liquidity pools. Returns come from trading fees and token incentives.
In yield farming:
- APY is more commonly used, as rewards are often distributed frequently and compounded.
- High volatility and impermanent loss risks mean advertised yields should be treated cautiously.
Unlike staking, yield farming is generally suited for experienced users due to its complexity and risk profile.
APR vs. APY: Which Is Better?
The answer depends on your role:
| Role | Preferred Metric | Reason |
|---|---|---|
| Investor/Lender | APY | Higher returns due to compounding |
| Borrower | APR | Lower effective cost of borrowing |
If all else is equal—a 6% APR versus a 6% APY—the APY delivers better returns for savers and investors because it includes compound growth.
But be cautious: some platforms advertise high APYs based on volatile token emissions that may decrease over time. Always verify:
- Compounding frequency
- Reward sustainability
- Underlying asset stability
Converting APR to APY: Making Fair Comparisons
When comparing investment options, ensure you're comparing apples to apples. If one platform lists APR and another lists APY, convert them using online calculators or the formula:
APY = (1 + APR/n)ⁿ – 1
For instance:
- 18% APY (Phemex) vs. 17% APR (another exchange)
- Assuming monthly compounding:
APY equivalent of 17% APR = (1 + 0.17/12)¹² – 1 ≈ 18.39%
In this case, the 17% APR actually offers a higher effective yield than the advertised 18% APY—highlighting why conversion matters.
Frequently Asked Questions (FAQ)
What’s the main difference between APR and APY?
APR reflects simple interest without compounding, while APY includes the effect of compounding interest over time, making it a more accurate measure of actual returns.
Does a higher APY always mean better returns?
Not necessarily. High APYs in DeFi may be driven by short-term token incentives that can diminish quickly. Always assess sustainability and risk before investing.
Can APY be lower than APR?
No—under normal conditions, APY is always equal to or greater than APR because it accounts for compounding.
How often is interest compounded in crypto platforms?
It varies: daily compounding is common in DeFi protocols, while some centralized exchanges offer weekly or monthly compounding.
Should I focus on APR or APY when choosing a staking pool?
Focus on APY if rewards are automatically reinvested. If payouts are manual, APR gives a clearer picture of base earnings.
Do I need to calculate APY manually?
No—most platforms display APY directly, and many websites offer free APR-to-APY calculators to simplify comparisons.
Final Thoughts
Both APR and APY are essential tools for evaluating crypto investment opportunities. While APR provides a simple baseline, APY gives a more realistic view of potential earnings, especially in environments where compounding occurs frequently.
When building your crypto portfolio:
- Use APY to compare passive income options like staking and yield farming.
- Be mindful of advertised yields that may not be sustainable.
- Leverage conversion tools to make accurate comparisons between APR and APY offerings.
With the right knowledge, you can maximize returns while minimizing confusion in the fast-evolving world of decentralized finance.
