What is APY?

What Is APY in Crypto?

APY (Annual Percentage Yield) represents the projected annualized return on crypto assets when rewards are compounded over time. In crypto lending, staking, or DeFi yield, APY assumes that earned rewards are reinvested back into the principal balance.

Because APY includes compounding, it reflects the effective annual return, not just the nominal rate.

However, crypto APYs are variable, not fixed. Rates fluctuate based on:

• Token supply and borrowing demand
• Staking participation rates
• Protocol incentives and liquidity mining programs
• Market volatility
• Platform-specific risk models

As a result, an advertised APY today may differ materially from the average yield earned over a full year. Rates can change weekly—or even daily—depending on the platform.

APY vs. APR

The distinction is straightforward:

• APR (Annual Percentage Rate) = Simple interest. No compounding.
• APY (Annual Percentage Yield) = Includes the effect of compounding.

Example:

• 10% APR paid monthly without compounding = 10% annual return.
• 10% APR compounded monthly ≈ 10.47% APY.

In crypto, platforms often advertise APY because compounding meaningfully increases effective yield—especially with high nominal rates.

What Crypto Platforms Pay Compounding Interest?

Many centralized and decentralized platforms offer compounding rewards. The mechanism differs:

• Centralized platforms (CeFi) may auto-compound rewards internally.
• DeFi protocols often require manual reinvestment unless auto-compounding vaults are used.
• Some wallets compound automatically at the protocol level (e.g., rebasing tokens or validator-level compounding).

If you’re comparing options, reviewing updated rankings and yield comparisons on Coin Interest Rate can help identify which platforms currently support compounding and how frequently rewards are reinvested.
