ILCalc

About

Many calculators for impermanent loss only support Uniswap V2 or contain errors with V3 concentrated liquidity math. Few address the key factor for your profit or loss: whether trading fees offset the loss. ILCalc accurately calculates impermanent loss for Uniswap V2, V3 concentrated liquidity, and Balancer weighted pools. It provides a chart of the IL curve, a comparison against simply holding assets, and the break even fee APR. The tool is free, runs entirely in your browser, and requires no wallet connection or registration.
