    How to use this DeFi yield calculator APY after fees

    Stress-test an observed DeFi pool APY after reward-token price changes, principal movement, performance fees and transaction costs. Results keep provider observations separate from user-controlled scenarios.

    Observed APY is a snapshot

    Base and reward APY come from the selected provider observation. MoonMath holds that rate constant only to calculate the selected period; it does not claim the rate will persist.

    Yield and principal risk are separate

    A positive reward can coexist with a falling deposit asset, impermanent loss, depeg, liquidation, smart-contract failure or inaccessible funds. Principal stress is shown separately instead of hidden inside APY.

    Costs and reward valuation

    Reward-token price stress, performance fees and transaction costs reduce the displayed net result. TVL and a stablecoin label are context, not protocol audits or safety guarantees.

    DeFi Yield FAQ

    What would this observed yield look like after costs and price stress?

    Stress-test observed DeFi pool APY after reward price changes, principal movement, fees and transaction costs. MoonMath labels the data basis for this tool as Observed, Formula, Model, Assumption.

    Is the DeFi Yield a prediction or recommendation?

    No. The DeFi Yield Reality Check is an educational scenario tool, not financial advice, a recommendation, or a forecast. Provider coverage, liquidity, routing, fees and market conditions can make real outcomes materially different.

    Is the observed DeFi APY guaranteed?

    No. APY, token prices, incentives, liquidity and protocol conditions can change. The result is a transparent scenario based on one observation.
