Impermanent Loss Calculator

Estimate impermanent loss in a liquidity pool

Providing liquidity to a 50/50 automated market maker pool exposes you to impermanent loss when the token prices diverge. This calculator estimates that loss from the price change and your initial position, so you can weigh it against the fees you earn.

Why impermanent loss happens

When you deposit two tokens into a 50/50 pool, the pool rebalances as prices move, selling the rising token and buying the falling one to keep the ratio. The result is that you end up with less value than if you had simply held the two tokens, and that gap is the impermanent loss. It is called impermanent because it reverses if prices return to where they started, but it becomes permanent if you withdraw while prices have diverged. Comparing it to the fees earned is how you judge whether providing liquidity paid off.

Weigh loss against fees

This is an estimate for planning from the figures you enter, not financial advice, and real outcomes depend on rates and rules that change. Confirm anything important with the relevant institution or a qualified adviser. The calculation runs entirely in your browser, so your financial figures are never uploaded.
