What Is Impermanent Loss?

An impermanent loss calculator estimates the value difference between holding tokens in an automated market maker (AMM) liquidity pool versus simply holding them in a wallet. When you provide liquidity to a pool, price divergence between the paired tokens causes the pool to rebalance, potentially leaving you with less value than if you had just held. This loss is called "impermanent" because it reverses if prices return to their original ratio. Our calculator shows the exact percentage loss and dollar impact for any price change scenario, all computed privately in your browser.

How to Use Impermanent Loss Calculator

Frequently Asked Questions

What is impermanent loss?

Impermanent loss is the difference in value between providing liquidity to an AMM pool and simply holding the same tokens. It occurs when the price ratio of paired tokens changes from your entry point.

When is impermanent loss the worst?

Impermanent loss is greatest when one token's price moves significantly relative to the other. A 500% price divergence in a 50/50 pool results in roughly 25% impermanent loss.

Does pool weight affect impermanent loss?

Yes. Unequal weight pools like 80/20 experience less impermanent loss than 50/50 pools for the same price change, because the higher-weight token dominates the pool's value.

Do I need to connect my wallet?

No. The calculator runs entirely in your browser with no wallet connection or blockchain interaction. Enter hypothetical or actual values manually and your data stays completely private.
