Two crypto platforms both show 12%. Put $1,000 on each for a year, and one pays you about $7 more than the other. The gap is not a trick, and it is not a fee. It comes down to one thing: compounding. APY, short for Annual Percentage Yield, is what you really earn in a year once your rewards start earning rewards of their own. APR, the Annual Percentage Rate, is the plain yearly rate with no compounding counted at all.
Key points:
- APY is your real yearly return once rewards are reinvested. APR is the plain rate with no compounding in it.
- The same 10% APR pays about $1,105 in a year if it compounds daily, and exactly $1,100 if it never compounds.
- In crypto, APY is almost always a moving number, so check the rate, the lock-up, and which token actually pays you.
APY counts the compounding, APR does not
APY stands for Annual Percentage Yield. It answers a plain question: If I leave my coins alone for a year, how much more will I have at the end? The number bakes in compounding, which means each payout joins your balance and starts earning too. APR stands for Annual Percentage Rate. It is the same yearly rate with the compounding stripped out, so it tells you the base rate and nothing about reinvestment.
The US Consumer Financial Protection Bureau defines APY in its Regulation DD rules as a rate that reflects both the interest rate and how often interest compounds over a 365-day period. Crypto platforms borrowed the same letters, but they do not all follow the same rules, so the number on screen deserves a second look.
The maths behind it is one short formula: APY = (1 + r ÷ n)^n − 1, where r is the APR written as a decimal and n is how many times a year rewards compound. What matters is the idea inside it: The more often rewards compound, the higher the APY climbs above the APR.
The same 10% can pay three different amounts
Take $1,000 at 10% APR. If rewards compound once a year, you end with $1,100 and the APY is 10%. If they compound every month, you end with about $1,105 and the APY is 10.47%. If they compound every day, you end with about $1,105 too, and the APY is 10.52%.
At 10%, the gap looks small. At higher rates it stops looking small. A 12% APR with no compounding gives you $120 on $1,000 in a year. The same 12% shown as an APY with daily compounding gives you about $127.47. Same headline number, $7.47 apart.

Where you actually see APY in crypto
APY turns up anywhere a platform pays you for letting it use your coins. The rate means something different in each place.
| Where it shows | What you do | How you get paid | What moves the rate |
|---|---|---|---|
| Staking | Lock coins to secure a network | More of the same coin | Network demand, validator cut |
| Lending | Lend coins to borrowers | Interest, often in the same coin | Borrower demand |
| Liquidity pools | Add two coins to a trading pool | Trading fees plus rewards | Trading volume, token price |
| Exchange Earn | Deposit coins in an exchange product | Interest or rewards | The exchange sets the terms |
Why a crypto APY is not a bank APY
A bank APY sits on dollars in a regulated account. A crypto APY sits on tokens whose price can fall while the rate still looks great. A 20% APY paid in a token that halves in price still leaves you down, because the rate counts coins, not dollars.
Crypto rates move, too. In mid-2026, Ethereum staking paid around 3% a year. In early 2026, Solana staking sat near 8–11%. Treat those ranges as a snapshot, not a promise: They come from staking dashboards and exchange pages, and they shift week to week.
My own read is simple: if a platform will not tell you how often it compounds, treat its APY as a sales number, not a fact. The honest ones print the APR, the compounding schedule, and the lock-up right next to the big number.
The mistake most people make: chasing the biggest number
Most people assume the highest APY wins. The numbers say otherwise. We already saw it: 12% APR with no compounding pays $120 on $1,000, while 12% APY with daily compounding pays about $127.47. A half-point gap in the fine print beats a full point in the headline.
A sky-high fixed APY with no clear source for the return is one of the most common scam signs in crypto. Real yield comes from somewhere: Staking rewards from a network, interest from borrowers, or fees from traders. If a platform cannot say where its yield comes from, the yield is the product, and you are the funding.
Read an APY in 4 quick steps
Before you put coins anywhere for yield, run these four checks. They take about five minutes, and they catch most bad offers.
- Ask how often it compounds. Daily beats monthly, and monthly beats yearly, at the same APR. If the platform will not say, walk away.
- Ask if the rate is fixed or variable. A variable rate can fall the week after you deposit, so treat it as a range, not a promise.
- Ask what token pays you, and whether your coins get locked. Rewards paid in a shaky token are worth less than the headline says, and locked coins cannot be sold in a crash.
- Ask where the return comes from. Staking rewards, borrower interest, and trading fees are real sources. No answer here is the loudest warning sign there is.
Write down four numbers before you start: The APR, the compounding schedule, the lock-up, and the reward token. Check the same four numbers a month later. If they moved, you will know exactly what changed, and whether the offer is still worth it.
