In the fast-evolving world of cryptocurrency and decentralized finance (DeFi), understanding financial metrics is essential for making informed investment decisions. Two of the most commonly used terms—APR and APY—are often seen when exploring staking rewards, lending platforms, or yield farming opportunities. While they may sound similar, their implications on your returns can be significantly different.
This guide breaks down the core distinctions between APR and APY, how they're calculated, and why they matter in crypto finance—especially when maximizing passive income or evaluating borrowing costs.
What Are APR and APY?
Annual Percentage Rate (APR) and Annual Percentage Yield (APY) both represent the annualized return on an investment or cost of borrowing. However, their calculation methods differ fundamentally.
- APR reflects simple interest—the rate earned or paid on the principal amount only.
- APY, on the other hand, includes compounding interest, meaning it accounts for interest earned on both the principal and previously accumulated interest.

Because APY factors in compounding, it typically results in a higher effective return than APR when all other conditions are equal. This makes APY a more accurate representation of actual earnings over time—especially in DeFi protocols where interest compounds frequently.
The Power of Compounding: Why APY Often Outperforms APR
Compounding is often referred to as the "eighth wonder of the world" in finance—and for good reason. When interest is reinvested at regular intervals (daily, monthly, etc.), your balance grows exponentially rather than linearly.
For example:
- A 5% APR on 10,000 USDC yields exactly 500 USDC after one year with no compounding.
- A 5% APY with semi-annual compounding yields approximately 506 USDC—a small but meaningful difference.
The formula for APY is:
APY = (1 + r/n)^n - 1Where:
r= annual interest rate (as a decimal)n= number of compounding periods per year
Using this formula:
- If a platform offers 5% APY compounded twice a year:
(1 + 0.05/2)^2 - 1 = 0.0506→ 5.06% effective yield
Even slight differences in compounding frequency can add up over time. Daily compounding will always generate a higher yield than monthly or quarterly, assuming the same nominal rate.
How APR and APY Are Used in Crypto
In decentralized and centralized financial ecosystems, APR and APY help users evaluate potential returns across various products.
Staking Rewards
Blockchains using proof-of-stake (PoS) mechanisms—like Ethereum and Solana—incentivize users to stake their tokens to secure the network. Rewards are typically advertised as either APR or APY.
- If shown as APR, the rate does not include reinvestment of rewards.
- If shown as APY, it assumes staked rewards are automatically compounded.

DeFi Lending and Borrowing
Platforms like Aave and Compound allow users to lend or borrow digital assets with interest rates displayed in real time.
- Lenders earn interest quoted as APY (with compounding) or APR (simple rate).
- Borrowers pay interest, often listed as APR to simplify repayment expectations.
Higher APYs for lenders mean higher borrowing costs—so these rates are interdependent.
Yield Farming and Liquidity Pools
On decentralized exchanges (DEXs) such as Uniswap or PancakeSwap, users provide liquidity by depositing token pairs into liquidity pools. In return, they earn trading fees and sometimes additional token incentives.
Returns from these activities are usually expressed as APY, which may include:
- Trading fee income
- Token emissions (incentives)
- Compounded reinvestment of rewards
Due to fluctuating market conditions and impermanent loss risks, these APYs can be variable or even misleading if not properly vetted.
Centralized Exchange (CEX) Savings Programs
Many centralized platforms offer flexible savings accounts with fixed or variable APYs. These are often more user-friendly than DeFi but come with counterparty risk since users don’t control their private keys.
APR vs APY: Which Should You Choose?
There’s no universal answer—it depends on your role in the financial transaction:
| Scenario | Better Metric |
|---|---|
| Earning passive income (staking, lending) | APY – Maximizes returns through compounding |
| Taking out a crypto loan | APR – Simpler, lower effective cost without compounding |
For savers and investors, APY gives a truer picture of growth potential. For borrowers, APR helps avoid surprises from escalating compound interest.
Always verify whether a platform displays APR or APY—and understand how frequently compounding occurs—to make accurate comparisons.
How to Find Reliable APR and APY Rates in DeFi
Transparency is key in DeFi. Most protocols display current rates directly on their dashboards:
- Lido Finance: Shows staking APRs for Ethereum, Solana, and Polygon.
- Aave: Lists borrowing and lending APYs under its Markets section.
- DeFiLlama: Offers a comprehensive "Yields" page that aggregates APY data across hundreds of protocols, sorted by total value locked (TVL).
However, extremely high yields should raise red flags. For instance, the now-defunct Anchor Protocol offered 19.5% APY on UST stablecoin deposits—a rate that proved unsustainable and contributed to the collapse of the Terra ecosystem in 2022.
High APYs often rely on:
- Incentive token emissions
- Unsustainable reserve drawdowns
- Low borrower demand
Always conduct due diligence before committing funds—even if the numbers look too good to pass up.
Frequently Asked Questions (FAQ)
What’s the main difference between APR and APY?
APR calculates simple annual interest without compounding, while APY includes the effect of compounding interest over time, resulting in a higher effective yield.
Does a higher APY always mean better returns?
Not necessarily. High APYs may come from volatile incentive programs or unsustainable models. Always assess protocol security, track record, and underlying economics.
Can APR ever be higher than APY?
No. Since APY includes compounding, it is always equal to or greater than APR when rates are positive.
How often is interest compounded in DeFi?
It varies by platform—common intervals include daily, hourly, or even every few minutes. More frequent compounding increases APY slightly compared to APR.
Why do some platforms show APR instead of APY?
Some platforms use APR to present a simpler, lower-looking rate—especially for borrowers. Always check whether rewards are compounded and how often.
Is APY guaranteed in crypto?
No. Most crypto APYs are variable and based on current network activity, liquidity levels, and token incentives. Returns can change daily or drop to zero if incentives end.
Final Thoughts: Make Smarter Decisions with Accurate Metrics
Understanding the distinction between APR and APY empowers you to compare financial products accurately and optimize your strategy—whether you're earning yield or managing debt in the crypto space.
Always look beyond headline numbers. Investigate:
- Compounding frequency
- Sustainability of yields
- Underlying protocol risks
- Historical performance
