How it works
k = new price ÷ old price
IL = 2√k ÷ (1 + k) − 1
Worked example
Token goes from $3,000 to $4,500 (1.5×): IL is −2.02%. On a $2,000 deposit the LP is worth about $50 less than holding, so you needed $50+ of fees to come out ahead.
FAQ
Why is it called impermanent?
If price returns to your deposit ratio the loss vanishes. Withdraw while prices are moved and it becomes permanent.
Is a 2× move bad for LPs?
A 2× move costs 5.72% versus holding. Big divergence hurts: a 5× costs about 25.5%.
Does this apply to stablecoin pairs?
Stable-stable pools barely diverge, so IL is near zero. That is why their fees can be lower and still attractive.
