Impermanent Loss Explained and Calculated: When LP Positions Underperform
Impermanent loss is the hidden cost of liquidity providing. This guide explains exactly how to calculate IL for any price movement, when it matters most, and how to mitigate it.
Impermanent loss (IL) is the opportunity cost of providing liquidity vs. simply holding the tokens. The term "impermanent" is misleading — IL only disappears if prices return to entry levels. If you withdraw with different prices, the loss is realized. Understanding IL is essential before providing liquidity in any volatile pool.
IL Calculation Examples
- ETH price doubles from $2,000 to $4,000: IL = 5.7% vs. HODL
- ETH price triples: IL = 13.4% vs. HODL
- ETH price 5x: IL = 25.5% vs. HODL
- ETH price 10x: IL = 42.5% vs. HODL — only justified by extraordinary fee income
When IL Does Not Matter
- Stablecoin/stablecoin pools (USDC/USDT): near-zero price divergence → near-zero IL
- Correlated assets (stETH/ETH): high correlation → minimal IL
- Short-duration LPs with high fee income: IL is smaller than fees earned
- Concentrated LP positions in narrow range: high fee APR compensates for in-range IL
IL Mitigation Strategies
- Favor stablecoin and correlated-asset pools
- Use Balancer's 80/20 pools: 80% BTC, 20% USDC reduces IL vs. 50/50
- Arrakis/Gamma: active LP management that adjusts ranges to minimize IL
- Exit positions when price deviates significantly from entry before IL compounds further
