APR to APY Conversion
Results
APY is always higher than APR when compounding occurs. The more frequent the compounding, the higher the APY.
Key Insight: For the same APR, APY will always be higher with more frequent compounding. For example, 10% APR compounded daily yields approximately 10.5% APY.
When you start looking at DeFi dashboards, the numbers that flash next to a pool often read APY or APR. Those letters decide whether you think a farm is worth the risk, but most newcomers treat them as interchangeable. In reality, they measure two very different things, and mixing them up can lead to costly mistakes. This guide breaks down what each metric really means, how they’re calculated, where you’ll see them in the crypto world, and how to use them to compare opportunities accurately.
What is APR?
APR is the annual percentage rate, a simple interest figure that shows how much you’ll earn (or pay) over a year without accounting for any compounding. Think of a traditional loan: if you borrow 1ETH at a 5% APR, you’ll owe 0.05ETH after a year, no matter how many days pass in between. In crypto, platforms often add fees, token distribution costs, or protocol charges into the APR calculation to give a clearer picture of the raw rate before any reinvestments happen.
What is APY?
APY stands for annual percentage yield. Unlike APR, it folds in the power of compound interest - the extra earnings you generate by reinvesting rewards back into the original position. If a protocol automatically restakes the tokens you earn, each new token also starts earning its own rewards. Over time, that snowball effect makes APY higher than the plain APR for the same nominal rate.
Compounding: The Core Difference
Both metrics start with the same base interest rate (let’s call it R). APR simply multiplies R by the number of years, while APY uses the formula (1 + R/N)^N - 1, where N is the number of compounding periods per year. More frequent compounding (daily, hourly, per block) pushes the APY up, sometimes dramatically. For example, a 10% nominal rate compounded daily yields about 10.5% APY, whereas the same rate compounded hourly approaches 10.52%.
How to Calculate APR and APY - Real‑World Numbers
- APR example: You lend 2ETH on a platform that offers a 6% APR. After 12 months you receive 0.12ETH in interest, regardless of any interim price changes.
- APY example: The same 6% nominal rate is compounded weekly (N=52). Using the APY formula, the yield becomes
(1 + 0.06/52)^52 - 1 ≈ 6.17%. If the protocol auto‑re‑stakes the earnings each week, you effectively earn 0.1234ETH instead of 0.12ETH.
These calculations matter most in Yield Farming where protocols often advertise both APR and APY so users can see the raw rate and the compounded reality.
Where You’ll See APR vs. APY in DeFi
Different activities favor different metrics:
- Staking & Liquidity Pools: Most reputable DeFi Protocol dashboards display APY because rewards are automatically re‑invested, and users need the full‑picture number.
- Lending & Borrowing: Platforms that offer fixed‑rate loans typically show APR. Since the borrower repays a set amount and the lender may not auto‑compound, APR gives a cleaner comparison.
- Simple Savings‑Style Products: Some newer services, like liquid staking providers, list APR to keep the math straightforward for users who prefer to withdraw rewards manually.
Understanding which metric a platform uses prevents the classic “APR looks better than APY” trap - the reverse is usually true when compounding is involved.
Practical Implications for Investors
When you line up two farms, make sure you’re comparing apples to apples:
- If Farm A shows 12% APR and compounds weekly, convert it to APY (≈12.6%) before stacking it against Farm B’s 12% APY.
- Factor in Platform Fees. A high APY can be eroded by a 0.5% performance fee taken each harvest.
- Consider external variables like trading volume, impermanent loss, and token emission schedules. Those can swing the effective yield far beyond the headline APR/APY.
Many traders use yield calculators that ingest APR, APY, compounding frequency, and fee structures to project net earnings over 30‑day, 90‑day, or 1‑year horizons. Those tools are indispensable for a realistic expectations set‑up.
Common Pitfalls and How to Avoid Them
Even seasoned DeFi users stumble over a few recurring mistakes:
- Ignoring Compounding Frequency: A protocol that compounds per block (≈15seconds) will push APY noticeably higher than one that compounds daily.
- Overlooking Token Price Volatility: APY is often quoted in the protocol’s native token. If that token’s price drops, the dollar‑value return may be far less.
- Misreading Fee Inclusions: Some platforms embed fees into APR (making it look lower) while showing a higher APY that excludes them. Always read the fine print.
- Assuming Stable Returns: Yield farms can change reward rates on the fly. A snapshot APY can become stale within hours.
Best practice: capture the current APR, convert it to APY using the disclosed compounding interval, subtract any performance fees, and then run a sensitivity analysis on token price swings.
Side‑by‑Side Comparison
| Aspect | APR | APY |
|---|---|---|
| Definition | Simple annual interest rate (no compounding) | Annual yield including compounding effects |
| Typical Use Cases | Lending, borrowing, fixed‑rate deposits | Staking, yield farming, liquidity provision |
| Formula | APR = (Periodic rate × 365) × 100 | APY = (1 + R/N)N - 1 |
| Impact of Fees | Often included in the rate calculation | Usually shown separately; net APY = gross APY - fees |
| Effect of Compounding Frequency | None (rate is flat) | Higher frequency → higher APY for same nominal R |
| Investor Perspective | Good for assessing borrowing cost | Best for estimating actual earnings over time |
Final Checklist for Evaluating a Yield Farm
- Identify whether the posted figure is APR or APY.
- Convert APR to APY using the protocol’s compounding schedule.
- Subtract any performance or withdrawal fees to get net APY.
- Run a token‑price sensitivity test (e.g., ±20%).
- Check recent reward‑rate changes; treat the APY as a snapshot, not a guarantee.
Frequently Asked Questions
Is a higher APY always better than a higher APR?
Not necessarily. A higher APY means more compounding, but you must also factor in fees, token volatility, and the underlying risk. Compare net returns after adjusting for those variables.
How often do DeFi platforms compound rewards?
It varies. Some protocols compound per block (every ~15 seconds), others do daily or weekly auto‑re‑stake. The compounding interval is usually listed in the farm’s details.
Can I convert an APR to APY myself?
Yes. Use the formula APY = (1 + R/N)^N - 1, where R is the APR expressed as a decimal and N is the number of compounding periods per year.
Why do some farming dashboards show both APR and APY?
Displaying both lets users see the raw rate (APR) and the realistic, compounded return (APY). It improves transparency and helps investors make informed choices.
Do platform fees affect APR, APY, or both?
Fees can be baked into APR on lending platforms, while many yield farms list fees separately, subtracting them from the gross APY to arrive at a net figure.

Hey folks! Just a quick rundown: APR is the nominal interest rate, while APY factors in compounding, so it’s usually higher. If you’re farming yields, always plug the APR into an APY calculator to see real returns. Daily compounding can bump a 10% APR up to around 10.5% APY, which matters over long periods. Remember to check the frequency – weekly or per‑block compounding will give you an even bigger boost. Happy farming! 😊
This whole APR/APY hype is just smoke and mirrors.
Alright, let’s peel back the glossy veneer that the DeFi evangelists love to plaster across every forum thread. APR, the so‑called Annual Percentage Rate, is essentially a nominal figure that pretends interest is a flat line, as if finance were a straight‑edge ruler. Yet the real world loved by yield farmers is anything but linear – compounding is the name of the game, and APY is the only metric that respects this chaotic reality. When you compare a 12% APR with daily compounding, you’ll see the APY creep up to roughly 12.75%, a modest bump that most influencers gleefully shout about. Now, let’s consider frequency: compounding per block – think 8,760 times a year for hourly or even more for per‑5‑minute windows – turns that 12% APR into a staggering 13.5% APY.
But here’s the kicker: most of these calculators ignore the underlying volatility of the underlying token, gas fees, and the slippage that eats away at yields. The glossy APY number is a crystal‑clear illusion if the protocol’s token drops 30% in price – your nominal return is wiped out. Moreover, many yield farms lock you into contracts that can be rug‑pulled or suffer from smart‑contract bugs; the APY becomes meaningless the moment the code is exploited.
So, while it’s tempting to chase the highest APY, a prudent farmer must consider risk‑adjusted returns. Look at the Sharpe ratio of the farm, factor in tokenomics, and ask yourself if the compounding frequency truly adds value or simply inflates vanity metrics. In short, APY > APR is a mathematical fact, but it’s not a guarantee of profit. The savvy investor knows that without accounting for risk, the APY is just another buzzword.
As an American investor, I gotta say that the U.S. market still offers the most reliable yield opportunities – those DeFi APY numbers are often just hype. 🇺🇸 When you compare them to Treasury yields, you see they’re not really that special. Stay grounded and don’t chase every shiny APY on the internet. 👍
Let’s dissect the metric calculus: the nominal APR is a baseline, but the exponential growth factor introduced by compounding transforms the linear trajectory into a geometric series. When you engage in high‑frequency yield farming, especially with per‑block rewards, the effective APY can dwarf the APR by a substantial coefficient. This is why liquidity providers should always calibrate their strategy against the compounding schedule – daily, hourly, or per‑block – to optimize the yield curve. In practice, the marginal gains from moving from weekly to daily compounding are non‑trivial, and the liquidity mining incentives often adjust accordingly.
Yo fam, so here's the lowdown on APR vs APY – APR is just the straight up interest rate, no compounding, kinda like the base salary before any bonuses. APY on the other hand is where the magic happens, cuz it adds that compounding effect and you end up with a bigger number, especially if you compound super often. Like, imagine you got a 10% APR and you compound daily, that turns into about 10.5% APY – not a huge jump but over years it adds up big time. Also watch out for hidden fees and gas costs, they can eat into that sweet APY like a hungry bear. So always run the numbers, keep an eye on the real net return, and maybe use an APY calculator to see the true picture. Keep it real, keep it safe! 🚀
Okay so the APY calculator is super useful when you want to see how compounding changes your returns. If you plug in a 15% APR and set the compounding to daily you’ll get around 16.1% APY – that’s a decent boost. Just make sure the APR you’re using is realistic, many projects overstate it. Also watch out for gas fees that can kill the profit especially on Ethereum. Stay aggressive and keep checking the numbers!
Hey team! Let’s make sure we all understand that APY takes the compounding frequency into account – so the more often you compound, the higher the APY. It’s a great way to compare different farming opportunities on a level playing field. Don’t forget to factor in transaction costs, they can eat into the yields. If you have any tips on low‑fee chains, drop them below! 🌟
In simple terms, APR is the yearly rate without compounding, while APY shows what you actually earn after compounding. Higher compounding frequency means higher APY. Use an APY calculator to see the real return on a farm.
Just a heads‑up: the APY numbers look great, but remember that they assume you keep the rewards in the same pool. If you move them elsewhere, the compounding effect disappears.
Wow, another post about APR vs APY – guess we’re still trying to wrap our heads around basic finance. Anyway, the key point is APY > APR when you compound, duh.
Great post! Understanding the difference helps keep us from over‑estimating yields. I always double‑check the compounding frequency before committing my tokens. Keep the good stuff coming! 👍
Did you know the whole APY thing is a ploy by the elite to distract us from the real money‑printing schemes?
It’s worth noting that the APY calculation assumes reinvestment of earnings, which isn’t always feasible for every farmer.
Not bad, but the post could’ve cut the fluff.
🚀Yo! APY is where the real fire lives – compounding is the engine that turns a sleepy APR into a blazing rocket. If you’re only looking at the flat APR, you’re missing out on the exponential gains that daily or per‑block rewards can give you. Watch those gas fees though, they can melt your profit faster than a heat‑sink on a GPU rig. Stay sharp, stay stacked! 💥
Hey guys, just a quick note – always verify the contract source before trusting the APY numbers. A shady contract can pump up the APY just to lure you into a rug pull. Stay safe!
Honestly, most of these APY calculators are just a marketing gimmick. If you look at the underlying tokenomics, the returns don’t justify the risk.
Pro tip: when you see a high APY, check if the protocol lets you auto‑compound your rewards. If not, the effective APY you earn will be lower than advertised.
From a cultural perspective, the fascination with APY mirrors the broader hype around yield‑farming in emerging markets. It’s a blend of finance and tech that’s reshaping how we think about returns.
APY is just APR with compounding but people get confused no punctuation needed 😜
Good point on the contract audit – I’ve seen farms where the APY looked insane until the code was flagged for a hidden fee. 😅
