# APY Calculations **APY** (Annual Percentage Yield) reflects the annualized return with compounding factored in. This is particularly useful for restaking, as Renzo auto-compounds rewards received from both staking and restaking, allowing users to save on gas fees and receive additional rewards. 1. **Auto-compounding** * Staking and restaking rewards are automatically redeposited into the protocol, increasing the amount of collateral a user is able to claim without increasing the supply of the asset. Thus, the price of the asset increases as rewards are harvested. No manual claiming is required. 2. **Determining APY** * The APY displayed in the app is calculated directly from the asset’s price change over a trailing observation window (default **30 days**) and annualized: `APY = (1 + (Δprice / starting price))^(365 / days) - 1` * **Δprice** = current price – starting price * **Starting price** = price at the beginning of the window * **Days** = number of days in the look-back period (defaults to 30) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
