“Impermanent” is a misleading name.
The loss becomes permanent the moment you withdraw. It measures how much less your position is worth than if you had simply held both tokens instead of supplying them to a liquidity pool. The figure assumes a constant-product pool (the Uniswap v2 style
x × y = k) with two tokens weighted 50/50, and excludes gas costs, token emissions and any deposit or withdrawal fees. Concentrated-liquidity and weighted pools behave differently. This is an informational calculation, not financial advice.
Impermanent loss is what a liquidity provider gives up compared with simply holding the two tokens. When the price of one token moves relative to the other, an automated market maker rebalances the pool, leaving you with more of the token that fell and less of the one that rose. The calculation here uses the constant-product formula behind Uniswap v2 style pools with two assets weighted 50/50, where loss depends only on the ratio of the two price changes, not on their direction. The name is misleading: the loss only reverses if prices return to their original ratio, and it becomes permanent the moment you withdraw. Trading fees and incentive rewards can offset it, which is why this tool lets you add them. It excludes gas costs and deposit or withdrawal fees, and concentrated-liquidity or unevenly-weighted pools behave differently.
Why is it called impermanent?
Because the loss reverses if the two token prices return to the ratio they had when you deposited. It becomes permanent as soon as you withdraw at a different ratio.
Does direction matter?
No. Loss depends on the ratio between the two tokens' price changes, so a token halving relative to its pair produces the same impermanent loss as it doubling.
Can fees offset it?
Yes, and often they do. Trading fees and incentive rewards accrue to liquidity providers, which is why this calculator lets you enter what you have earned and see the net position.
Does this apply to every pool?
No. It models a constant-product pool with two assets weighted 50/50. Concentrated-liquidity pools and unevenly-weighted pools have different, usually sharper, loss profiles.
