Impermanent Loss Calculator
See how much a 50/50 liquidity position underperforms simply holding when the two token prices diverge.
Impermanent loss vs. holding
5.72%
That is a meaningful gap: about 5.72% behind holding. Large one-sided moves are where liquidity providers get hurt, and fees rarely make up for a divergence this size.
Quick reference (one token moves, the other stays flat)
| Price move | Impermanent loss |
|---|---|
| 1.25x (+25%) | 0.62% |
| 1.5x (+50%) | 2.02% |
| 2x (+100%) | 5.72% |
| 3x (+200%) | 13.40% |
| 5x (+400%) | 25.46% |
How this is calculated
IL = 2 * sqrt(r) / (1 + r) - 1, where r = (1 + changeA) / (1 + changeB)
- Models a standard 50/50 constant-product pool (Uniswap V2 style).
- Shows loss versus holding only. It does not add the trading fees a real pool earns, which offset some or all of the loss.
- Concentrated-liquidity pools (Uniswap V3) can amplify this within a chosen range.
