How this calculator works
01
Enter deposit value, pool weight, relative price change, fee APR, and time in the pool.
02
CoinCalcs validates the manual inputs and applies this published model: IL = LP value after price change ÷ hold value after price change − 1
03
The result is calculated locally in the browser and is not sent to CoinCalcs or a market-data provider.
Formula
The calculation
IL = LP value after price change ÷ hold value after price change − 1Example
A concrete scenario
In a 50/50 pool, one asset doubling while the other is unchanged creates about 5.72% impermanent loss before earned fees.
