Impermanent Loss Calculator
The divergence loss of an AMM liquidity position versus simply holding — by price change ratio, the exact constant-product formula.
Formula
Impermanent loss is the opportunity cost of providing liquidity versus holding — it grows with price divergence (a 2× move = 5.7% IL, 5× = 25.5%). It's 'impermanent' only because it reverses if prices return; it becomes permanent the moment you withdraw. LP fees and rewards must out-earn it.
Educational — DeFi positions carry smart-contract and market risk. Not financial advice — for informational and analytical use only. Verify all figures with a qualified professional before acting on them.
