Impermanent Loss Calculator
Estimate impermanent loss for any 50/50 AMM liquidity pool. Compare what your deposit would be worth as a passive HODL versus actively in the pool, before fees. Stress-test scenarios in seconds.
Price ratio shift: 1.500x (Token A appreciated relative to the other)
Standard Uniswap V2-style 50/50 constant-product pool. Trading fees not included — real LP returns offset some IL. Concentrated liquidity (V3) and stable pools follow different formulas.
How impermanent loss works
An automated market maker rebalances your two-token position to keep their USD values equal at all times. When one token's price moves relative to the other, the AMM sells some of the appreciating side for the depreciating side — the opposite of what a HODLer would do.
The gap between "value if I'd just held both tokens" and "value of my LP position now" is impermanent loss. It is real money you don't get back unless prices return to their original ratio.
Trading fees can offset IL — sometimes entirely, often not. Use this calculator alongside fee APR estimates from Revert Finance or DeFiLab to estimate net P&L.
Limits of this calculator
- Standard 50/50 constant-product pools only (Uniswap V2-style).
- Concentrated liquidity (Uniswap V3) follows a different curve — IL inside the active range can be much larger.
- Stable pools (Curve, Balancer composable stable) use a different invariant; IL is typically much smaller.
- Trading fees and reward tokens are not included — you must add your real fee APR estimate.
