Impermanent Loss Calculator
Calculate exactly how much impermanent loss your liquidity position suffers at any price change. Factor in trading fees, compare LP returns against simply holding, and find the breakeven fee APR you need to come out ahead. This calculator uses the standard constant-product AMM formula used by Uniswap v2, SushiSwap, PancakeSwap, and most other decentralized exchanges.

LP Value + Fees vs HODL
IL Curve — Your Position
Impermanent Loss at Common Price Changes
This table shows impermanent loss at standard price multiples. The "Fees Needed" column shows the annual fee APR required over your chosen time period to fully offset the IL. Notice that IL is symmetric on a ratio basis: a 2x increase and a 0.5x decrease produce the same IL percentage.
| Price Change | New ETH Price | IL % | IL $ Loss | LP Value | HODL Value | Breakeven APR |

Multi-Pool Comparison
Compare up to three different pools side by side. Each pool can have a different fee tier and APR. The chart shows the net return (after impermanent loss) for each pool at the current price change you set above. This helps you decide which pool tier is most profitable for your outlook.
IL Over Time — How Fees Accumulate
This animated chart shows how your LP position value evolves over a full year. Fee income accrues linearly day by day, while impermanent loss is a function of price divergence. Over time, fees can compensate for IL — or not, depending on the APR. Adjust the price volatility slider to simulate price fluctuation around your target price change.
How Impermanent Loss Works
A brief refresher on the mechanics behind impermanent loss. For a deep dive with more visualizations, see our full explainer.
When you deposit tokens into a constant-product AMM (like Uniswap v2), the pool automatically rebalances your holdings as prices move. If ETH doubles in price, the pool sells your ETH for more USDC to maintain the constant product invariant (x * y = k). You end up with more of the depreciating asset and less of the appreciating one. The "loss" is the difference between what your LP position is worth and what you would have had by simply holding both tokens in your wallet.
The loss is called "impermanent" because it disappears if the price ratio returns to what it was when you deposited. However, if you withdraw while the ratio has diverged, the loss is crystallized and becomes very permanent. This is why understanding the relationship between IL and fee income is critical for any liquidity provider. A pool that generates enough fee income to exceed the IL is profitable; one that does not is a net loser compared to holding.
High trading volume drives substantial fee income.
Token incentive rewards further boost returns.
Prices return to entry ratio before you withdraw.
Low trading volume means fees do not compensate for IL.
Concentrated liquidity ranges are missed entirely.
Reward token dumps, wiping out incentive gains.
