Impermanent loss is the gap between holding the two tokens and providing them as liquidity — it only becomes permanent if you withdraw while the price ratio is shifted, and swap fees you earn while providing can offset or exceed it.
How to use this calculator
Set your total deposit and how far the token has moved against the other side of the pool (a stablecoin, usually). “Value in the pool” is what your position is worth as an LP; “if you held” is what the same tokens would be worth untouched. The gap is impermanent loss. Learn the mechanics in impermanent loss explained and how pools price trades in what is an AMM.
Frequently asked questions
What is impermanent loss?
It is the difference in value between holding two tokens and depositing them into a liquidity pool, once their relative price has moved. Nothing is stolen — the pool rebalances you out of the rising asset — but you can end up with less than if you had done nothing.
How is impermanent loss calculated?
For a 50/50 constant-product pool, if the token’s price multiplies by k against its pair, the loss versus holding is 2·√k / (1 + k) − 1. This calculator applies that formula and shows the dollar gap.
Does impermanent loss include fees?
No. This shows the price-divergence loss only. Swap fees earned while providing liquidity are separate and can offset or exceed it, especially in high-volume pools.
