How do you calculate impermanent loss?

If Investor A had left the initial 1 ETH and 100 DAI in a crypto wallet, the value of their assets at the new market price would be $300. The impermanent loss in this example can be calculated by subtracting $282.82 from $300 . The impermanent loss is $17.17.

In constant product AMMs like Uniswap v2 and SushiSwap, impermanent loss is computed by comparing the relative change in portfolio value V compared to a “holding” portfolio V_H in response to a small change P’→α P in the price of the underlying . where the range factor r = √(tH/tL).

Impermanent loss (IL) is the risk that liquidity providers take in exchange for fees they earn in liquidity pools . If IL exceeds fees earned by a user when they withdraw, it means the user has suffered negative returns compared with simply holding their tokens outside the pool.
