What Is APY in Crypto?
Seeing sky-high APY on crypto? What APY actually means, how it differs from APR, why big numbers are a red flag, and the Australian tax angle.
By Timothy Hirou GaschereauPublished 7 min read
You are browsing a crypto app and there it is: "Earn 12% APY." Then another one promising 80%. Before you move a cent, it pays to understand what APY actually means, why the number is often bigger than the real return, and why an eye-watering APY is usually a warning sign rather than a windfall.
🎯 The essential: APY (Annual Percentage Yield) is the return you earn over a year including compounding, which is why it always looks higher than APR, the flat rate. Crypto platforms advertise APY because the number is bigger, not because the product is safer. Very high APYs often come from volatile token rewards or inflationary emissions, not real revenue. In Australia, crypto staking rewards are generally taxed as ordinary income. This is general information, not financial advice, and crypto is high risk.
What APY means (and how it differs from APR)
APY stands for Annual Percentage Yield. It tells you the total return over one year, including the effect of compounding. APR (Annual Percentage Rate) is the flat yearly rate with no compounding. Compounding means earning returns on your returns: each time rewards are added to your balance, the next round is calculated on the new, larger total. That is why APY is always higher than APR for the same underlying rate, and why platforms prefer to advertise it.
| APY | APR | |
|---|---|---|
| What it measures | Total yearly return with compounding | Flat yearly rate, no compounding |
| Includes compounding? | Yes | No |
| Which looks higher? | APY (always) | APR (lower for the same rate) |
| Where you see it | Staking, earn products, DeFi | Loans, some savings products |
A worked example: why APY is higher than the flat rate
Say you deposit $1,000 into a crypto earn product advertising 10% a year. With simple interest (APR), you earn $1,000 x 10% = $100, ending at $1,100. With 10% compounded monthly (APY), you end at about $1,104.71, an extra $4.71. On small amounts it looks minor. On $100,000 that same gap is $471 in a single year, and it widens every year compounding continues.
The point is not that $4.71 changes your life. It is that platforms advertise APY precisely because it makes the number look bigger. Always check whether a rate is APY or APR before comparing products, the same way you would with a high-interest savings account.
Where you see APY in crypto
APY shows up across several activities. The number can look similar, but the mechanics and risks are very different.
- Staking rewards. You lock up proof-of-stake tokens to help validate a network, and it pays you rewards. See our guide to crypto staking in Australia.
- Lending and earn products. You deposit crypto on a platform that lends it out and pays you a share of the interest.
- DeFi liquidity provision and yield farming. You supply crypto to decentralised protocols that use it to facilitate trading or lending, paying you fees and token rewards.
The same APY on three different products can represent three very different levels of risk.
Why crypto APYs can look so high (and why that is a warning sign)
High advertised yields deserve serious scrutiny. The number usually looks big for a reason:
- Rewards paid in a volatile or new token. If the reward token drops 80%, your "20% APY" becomes a real-terms loss.
- Inflationary token emissions. Minting new tokens to pay rewards dilutes value. The yield exists on paper while the underlying value is watered down.
- Platform and counterparty risk. Centralised earn products rely on the platform staying solvent, secure and honest. If it freezes withdrawals or collapses, your funds may be gone.
- Smart-contract risk in DeFi. A bug or exploit can drain an entire liquidity pool in minutes, with no recourse.
A real example: Celsius Network advertised high yields on crypto deposits, then in June 2022 froze all withdrawals and filed for bankruptcy, leaving hundreds of thousands of users unable to access their funds. If the yield looks too good to be true, it probably is. A 50% APY is not a gift, it is a signal to ask hard questions about where that yield actually comes from.
Variable vs fixed APY: advertised rates are not guaranteed
Most crypto APYs are variable, changing daily or weekly with network conditions, token prices and platform demand. A rate advertised today may be completely different next week, because the APY you see is a snapshot, not a contractual promise. "Fixed" APY products exist, but they still carry platform risk and often lock your funds up, so if the platform fails during a lock-up, your money is at risk regardless. Never treat an advertised APY as guaranteed income.
The Australian tax angle
The ATO has clear crypto guidance. In general, staking rewards and other crypto yield are treated as ordinary income at the AUD value of the tokens when you receive them, added to your taxable income for the year. When you later sell those tokens, that is a separate CGT event, and holding for more than 12 months may qualify for the 50% CGT discount, though the rules are nuanced.
Australian exchanges report to the ATO, which uses data-matching, so keep detailed records of every reward and its AUD value at receipt. For the full breakdown, see our guide to crypto tax in Australia, and consult a registered tax agent.
How to evaluate a crypto APY sensibly
Before committing funds to any yield product, work through these questions:
- What is actually paying the yield? Real revenue from lending or fees, or newly minted tokens with no underlying demand? If you cannot answer clearly, that is a red flag.
- What are the risks? Reward-token volatility, smart-contract risk, counterparty risk, and what happens if the platform fails.
- Is the platform reputable and registered? Australian exchanges must be registered with AUSTRAC. Check before depositing.
- What are the lock-up and withdrawal terms? Some products lock funds for weeks or months, so you may not be able to exit if the market turns.
- Is the yield paid in a stable asset or a volatile token? Yield in a major stablecoin is very different from yield in a small-cap protocol token.
Every yield has a source, and every source has a risk. The higher the APY, the more important it is to understand exactly what that source is.
APY includes compounding and APR does not, so APY always looks higher for the same rate. Platforms advertise it because the number is more attractive, not because the product is safer. High crypto APYs usually reflect high risk: volatile token rewards, inflationary emissions, platform insolvency or smart-contract exploits. Celsius's 2022 collapse is a real reminder that high yields are not guaranteed. In Australia, staking rewards are generally taxed as ordinary income, so keep records and see a registered tax agent.
❓ Frequently asked questions
Is APY the same as an interest rate?
+
Not exactly. An interest rate is the base rate charged or paid. APY is the effective annual return after compounding is applied. For the same base rate, APY will always be higher than the simple interest rate.
Is a higher APY always better?
+
No. A higher APY often signals higher risk. In crypto especially, a very high APY can mean rewards are paid in a volatile token, the protocol is unsustainable, or the platform carries significant counterparty risk. Always look at what is generating the yield, not just the number.
Can I lose money even with a high APY?
+
Yes, absolutely. If the token you are earning drops in value, the platform becomes insolvent, a smart contract is exploited, or your funds are locked up during a market crash, you can lose some or all of your money regardless of the advertised APY.
Are crypto earn and savings products safe in Australia?
+
Crypto products are not covered by the government's Financial Claims Scheme, which protects bank deposits up to $250,000 per person per authorised institution. Crypto earn products carry platform, counterparty and regulatory risk. They are not equivalent to a bank savings account. This is general information, not advice.
Do I pay tax on crypto staking rewards in Australia?
+
The ATO generally treats staking rewards as ordinary income, assessable at the AUD value when you receive them. A later disposal of those tokens is a separate CGT event. Tax rules are complex and personal, so see a registered tax agent for advice specific to your situation.
What happened to platforms like Celsius that offered high yields?
+
Celsius Network was a centralised crypto lending platform that advertised high yields on deposits. In June 2022 it froze all customer withdrawals and subsequently filed for bankruptcy, leaving hundreds of thousands of users unable to access their funds. It is a documented example of the counterparty risk in centralised yield products.
