About this formula
- •Applies to constant-product AMMs (Uniswap V2, SushiSwap, PancakeSwap V2) with 50/50 weightings.
- •IL =
2·√r / (1 + r) − 1whereris the ratio change of A/B prices. - •IL is always ≤ 0 vs HODL. It only becomes a realized loss on withdrawal — hence "impermanent".
- •Weighted pools (Balancer) and concentrated liquidity (Uniswap V3) have different, generally larger IL profiles.
Fee APR is applied linearly on the initial deposit for simplicity. Real pools accrue fees on the current LP value and compound continuously, so very volatile or very long positions may see slightly higher fee income than the estimate.
