Crypto APY from APR Calculator

About the Crypto APY from APR Calculator

Annual Percentage Rate (APR) and Annual Percentage Yield (APY) are two of the most important metrics in crypto finance, yet they're frequently confused. APR represents the simple interest rate without compounding, while APY accounts for the effect of compounding over a year. The difference can be dramatic — a 100% APR compounded daily yields an APY of roughly 171.5%.

In decentralized finance, protocols advertise both metrics interchangeably, making it essential to convert between them accurately. Yield farms, staking platforms, and lending protocols each compound at different frequencies — some every block, some daily, some weekly. Understanding the true APY lets you compare opportunities on equal footing.

Our Crypto APY from APR Calculator takes your nominal APR and compounding frequency and returns the effective APY. Whether you're evaluating a new staking pool, comparing DeFi vaults, or simply verifying a protocol's claims, the calculator gives you the real number.

Use the result to map token-release or fee scenarios and revisit the model when market conditions, unlock terms, or portfolio assumptions change.

When This Page Helps

Protocols often display APR to make yields look lower (or APY to make them look higher). Converting APR to APY reveals the true return you'll earn after compounding. This is crucial when comparing staking options, DeFi vaults, and lending platforms that compound at different intervals.

How to Use the Inputs

1. Enter the nominal APR (annual percentage rate) offered by the protocol.
2. Select the compounding frequency (daily, weekly, monthly, or custom).
3. View the calculated APY — the effective annual yield after compounding.
4. Compare different APR/frequency combinations to find the best deal.
5. Use the result to set realistic return expectations for your portfolio.

Example Calculation

Tips & Best Practices

• Daily compounding is standard in most DeFi protocols — but always verify.
• The higher the APR, the bigger the gap between APR and APY.
• Some protocols auto-compound; others require manual restaking (which costs gas).
• Block-level compounding (every ~12s on Ethereum) is nearly equivalent to continuous compounding.
• Always compare APY-to-APY, not APR-to-APY, when evaluating yield opportunities.
• Factor in gas costs for manual compounding — they can erase the compounding benefit.

Understanding Compounding in Crypto

Compounding is the engine behind exponential growth in DeFi. When your rewards are reinvested, they begin earning their own rewards. Over time, this creates a snowball effect where returns accelerate. The frequency of compounding directly impacts how quickly this snowball grows.

Common Compounding Frequencies

Most auto-compounding vaults restake daily or even per-block. Manual staking typically compounds whenever you claim and restake — weekly or monthly for many users. Lending protocols like Aave accrue interest per block, effectively giving continuous compounding.

Why APR vs APY Matters for Large Positions

For a $10,000 position at 50% APR, the difference between no compounding ($5,000 earned) and daily compounding ($6,482 earned) is nearly $1,500 over a year. As principal grows, the absolute dollar gap widens, making APY the more honest measure of expected return.

Frequently Asked Questions

• What is the difference between APR and APY?

  APR is the simple annual interest rate without compounding. APY includes the effect of compounding — earning interest on your interest. APY is always equal to or higher than APR for the same nominal rate.

• Why do DeFi protocols show APR instead of APY?

  Some protocols display APR because it's easier to calculate and doesn't assume a compounding frequency. Others show APY to make yields look more attractive. Always check which metric is being shown before investing.

• How often do DeFi protocols compound?

  It varies widely. Auto-compounding vaults may compound daily or even per-block. Manual staking requires you to claim and restake rewards yourself, effectively compounding at whatever frequency you choose.

• Does higher compounding frequency always mean higher APY?

  Yes, mathematically more frequent compounding produces a higher APY for the same APR. However, the marginal benefit decreases — going from annual to daily compounding matters a lot, but daily to per-block barely changes the result.

• Can APY be lower than APR?

  No. For a positive APR with at least one compounding period, APY will always be equal to (annual compounding) or greater than (more frequent compounding) the APR.

• How do I account for gas fees in APY calculations?

  Subtract the total annual gas cost from your expected earnings before calculating effective APY. If manual compounding costs $5 per transaction and you compound daily, that's $1,825/year in fees — which can destroy returns on smaller positions.
