You find a staking pool advertising 12% returns. Another platform offers 11.4% on the same token. The choice seems obvious, until you realise one number is APY and the other is APR. That single distinction can mean hundreds of dollars in difference on a $10,000 deposit over a year, and most crypto investors never check which metric they are looking at.
APY and APR are the two most common ways to express yield in DeFi and staking. They sound interchangeable, and platforms rarely explain the difference. This article breaks down what each term means, how compounding turns one into the other, and what to actually look for when you are comparing staking opportunities.
What Is APR?
APR stands for Annual Percentage Rate. It represents the simple interest you would earn on a deposit over one year, without any compounding. If a staking protocol offers 10% APR on a $10,000 deposit, you earn $1,000 in rewards over the year. That is it. The calculation does not assume you do anything with the rewards once they arrive in your wallet.
APR is straightforward. You deposit capital, you earn a flat rate on that capital, and the rewards sit wherever they land. If the protocol pays rewards weekly, you receive roughly $19.23 each week ($1,000 divided by 52). Those weekly payouts do not themselves earn additional rewards unless you manually restake them.
In traditional finance, APR is the standard metric for loans, credit cards, and savings accounts. In crypto, you will see it used most often by staking protocols that do not automatically reinvest your rewards, like native ETH staking or Cosmos-based chains where rewards accumulate in a claimable balance.
What Is APY?
APY stands for Annual Percentage Yield. It represents the total return you would earn over one year if your rewards were automatically reinvested at the same rate on a regular schedule. The key word is "compounding": your rewards earn their own rewards, and those secondary rewards earn rewards as well.
If a protocol advertises 10% APY with daily compounding, it means you would end the year with more than $1,000 in rewards on a $10,000 deposit because each day's small reward gets added to your principal balance before the next day's reward is calculated.
APY is a more complete picture of what you actually earn if compounding happens automatically. Many DeFi vaults, auto-compounding staking services, and yield aggregators use APY because their smart contracts handle the reinvestment for you.
The Key Difference: Compounding
The entire gap between APR and APY comes down to one concept: compounding. With APR, your base deposit stays the same all year. With APY, your effective deposit grows every time rewards are reinvested.
Think of it this way. APR answers the question: "What is the base rate?" APY answers: "What do I actually take home if I reinvest on schedule?" At low rates and infrequent compounding, the difference is negligible. At higher rates with daily compounding, it becomes significant.
Compounding frequency matters too. The same APR produces different APYs depending on whether compounding happens annually, monthly, weekly, or daily. Daily compounding always yields slightly more than monthly, which yields more than quarterly. The formula connecting them is:
APY = (1 + APR / n)^n - 1
Where n is the number of compounding periods per year. For daily compounding, n equals 365. For monthly, n equals 12.
APY vs APR: A Practical Example
Let us put real numbers behind this. You deposit $10,000 into a staking protocol that offers a base rate of 10% per year. Here is what you end up with depending on compounding frequency:
- No compounding (10% APR): You earn $1,000. End balance: $11,000.
- Monthly compounding (10% APR, 12 periods): APY = (1 + 0.10/12)^12 - 1 = 10.47%. You earn $1,047. End balance: $11,047.
- Daily compounding (10% APR, 365 periods): APY = (1 + 0.10/365)^365 - 1 = 10.52%. You earn $1,052. End balance: $11,052.
The difference between no compounding and daily compounding at 10% is $52 on a $10,000 deposit. That may seem modest, but scale it to $100,000 and it is $520. Run it for three years with the same rate and the gap widens to over $1,600. Compounding is not magic, but it is real money, and the effect accelerates at higher rates and longer time horizons.

Why DeFi Platforms Show APY
If you have browsed yield farms or staking dashboards, you have probably noticed that most platforms default to showing APY. The reason is simple: APY is the larger number, and a larger number attracts more deposits.
A protocol with a 50% APR can advertise roughly 64.8% APY with daily compounding. At 100% APR, the daily-compounded APY jumps to about 171.5%. The higher the base rate, the bigger the gap between APR and APY, and the more inflated the headline number looks.
This is not inherently dishonest if the protocol actually auto-compounds your rewards. In that case, the APY figure is what you would genuinely receive. The problem arises when a platform displays APY but does not compound for you. In that scenario, you would need to manually claim and restake your rewards daily to actually achieve the advertised yield, and gas fees on each restaking transaction can eat heavily into the returns.
Always check whether a protocol auto-compounds. If it does not, the APY number is aspirational at best and misleading at worst. Look for the APR figure instead and decide whether the manual effort of restaking is worth the marginal gain.
How to Convert Between APY and APR
When you are comparing two staking options and one shows APR while the other shows APY, you need to convert them to the same metric. Here are both directions:
APR to APY: APY = (1 + APR / n)^n - 1
APY to APR: APR = n * [(1 + APY)^(1/n) - 1]
For example, suppose Protocol A offers 12% APR with no auto-compounding, and Protocol B offers 12.2% APY with daily compounding. Converting Protocol B's APY back to APR: APR = 365 * [(1 + 0.122)^(1/365) - 1] = approximately 11.52%. So Protocol A's base rate of 12% is actually higher. If you are willing to manually restake on Protocol A, you would earn more.
These conversions are straightforward with a calculator, and you can use our Staking Calculator to model both scenarios side by side without doing the math yourself.
Red Flags: When Advertised Yields Are Misleading
Not all yield advertisements are created equal. Here are the warning signs that a displayed rate is not what it seems:
- APY shown but no auto-compounding. If the protocol pays out rewards to your wallet and expects you to restake manually, the APY figure overstates your actual return. Ask: does the smart contract reinvest for me, or am I doing it myself?
- Yields paid in a volatile governance token. A 200% APY means little if the reward token drops 80% in value over the same period. Calculate your expected return in dollar terms, not just token terms. Our Profit Calculator can help you model different price scenarios.
- Extremely high rates with no clear source of revenue. Yield has to come from somewhere: trading fees, borrowing interest, protocol revenue, or token emissions. If a protocol offers 500% APY and you cannot identify where the money comes from, the money is probably coming from new depositors. That is not yield; that is a structure that eventually collapses.
- Rates that change retroactively. Some protocols adjust rates based on total deposits. The 20% APY you saw when you deposited may drop to 4% once the pool attracts more capital. Check whether the rate is fixed or variable, and how often it adjusts.
- Ignoring lock-up periods and penalties. A 15% APY with a 90-day lock-up carries different risk than a 12% APY with instant withdrawal. If the token price crashes during your lock-up window, you cannot exit. Factor in the opportunity cost and illiquidity risk.
What to Look For
When evaluating any staking or yield opportunity, build a habit of checking these specifics before depositing:
- Is the displayed rate APR or APY? This is the most basic question and the one most people skip. Look for fine print, tooltips, or documentation that clarifies which metric is being used.
- Does the protocol auto-compound? If yes, APY is the accurate metric. If no, focus on APR and decide whether you will manually restake frequently enough to approximate the APY.
- What token are rewards paid in? Rewards in the same token you staked (like earning ETH on staked ETH) are fundamentally different from rewards paid in a separate governance or incentive token that may lose value.
- What is the compounding frequency? Daily, weekly, or some other interval? More frequent compounding means the APY will be higher relative to the APR, but the difference is marginal once you move past daily.
- Are there fees on compounding? Auto-compounding vaults often charge a performance fee (typically 5–20% of rewards) that reduces your effective yield. A vault advertising 15% APY with a 20% performance fee nets you closer to 12%.
- Is there a lock-up or unbonding period? Locked staking can offer higher rates, but you sacrifice the ability to exit if conditions change. Weigh the extra yield against the liquidity risk.

The difference between APR and APY is not complicated once you understand that compounding is the only variable separating them. But that simple difference gets exploited constantly in DeFi marketing. Protocols have every incentive to show you the highest possible number, and your job as a depositor is to normalise every opportunity to the same baseline before comparing.
Run the conversions. Check whether compounding is automatic or manual. Verify what token the rewards are paid in and whether it holds value. The few minutes you spend on this due diligence will pay for themselves many times over, especially as your staking positions grow larger.
Frequently Asked Questions
What is the difference between APY and APR in crypto?
APR is the simple annual interest rate without compounding. APY includes the effect of compounding, where earned rewards are reinvested to generate additional returns. APY is always equal to or higher than APR for the same underlying rate. The gap between them grows with higher rates and more frequent compounding.
Why do DeFi platforms show APY instead of APR?
Most DeFi platforms display APY because compounding makes the number larger and more appealing to potential depositors. A 50% APR becomes roughly 64.8% APY with daily compounding. This is accurate if the protocol auto-compounds, but misleading if it does not.
Is APY or APR more accurate for crypto staking?
Neither is inherently more accurate. APR shows the base rate before compounding, and APY shows what you would earn with perfect reinvestment. For comparing protocols fairly, convert everything to the same metric and confirm the compounding frequency. Use our Yield Calculator to model both.
How do I convert APR to APY?
Use the formula: APY = (1 + APR / n)^n - 1, where n is the number of compounding periods per year. For daily compounding, n = 365. A 10% APR compounded daily produces an APY of approximately 10.52%.
Can a 1,000% APY be real?
Extremely high APY figures are almost always temporary or misleading. They typically rely on token emissions that dilute the reward token's value, so your rewards lose purchasing power as fast as they accumulate. A 1,000% APY paid in a token that drops 90% in value leaves you worse off than a stable 5% APY paid in ETH or a stablecoin. Always check the source of yield before trusting the number.
