What is DifiCalc?
DifiCalc is a free suite of seven DeFi calculators built for investors who want clear numbers before they commit capital. Instead of juggling spreadsheets or trusting marketing pages, you get live, on-chain data pulled directly from DeFiLlama covering more than 200 protocols across every major chain. The APY comparison calculator lets you stack Yearn, Beefy, Aave, Compound, dYdX, GMX and Hyperliquid side by side, with historical yield trends so you can see whether a rate is sustainable or a temporary incentive. The impermanent loss calculator models real pair volatility and shows your breakeven price before you provide liquidity. A dedicated stablecoin tracker monitors rates across lending markets and flags depeg risk, while the risk rating engine scores protocols on TVL depth, audit history, treasury composition and time in operation. For portfolio builders the AI allocation tool suggests weightings based on your risk profile, then shows the projected blended yield. Every calculator works without signup, without wallet connection and without paywalls. Whether you are parking stablecoins at 8 percent or farming incentives on a new chain, DifiCalc gives you the same institutional-grade numbers that funds pay for, completely free. Bookmark your scenarios, compare chains, and make the yield decision that fits your risk appetite.
What problem it solves
DeFi yields change hourly and most investors guess. DifiCalc replaces gut feeling with live data: you see real APYs, hidden risks and modeled impermanent loss before you deposit.
