Assumes a standard 50/50 constant-product pool. Real pools also earn trading fees and rewards, which can offset impermanent loss.
How the calculation flows
Impermanent loss is the gap between simply holding two assets and providing them to a 50/50 liquidity pool after their prices move apart. Enter how far each asset’s price has moved and the calculator returns the loss relative to holding, the resulting price ratio, and the trading fees you would need to earn to break even. It assumes a standard constant-product pool and ignores rewards, so treat it as an illustration of the mechanism rather than a precise forecast.
FAQ
Is impermanent loss a real loss?
It only becomes realised if you withdraw while prices are diverged. It is called impermanent because it can shrink or disappear if prices return to their original ratio.
Do both inputs have to be volatile coins?
No. Enter the percentage price change for each pooled asset; a stablecoin simply has a change near zero.
