ILCalc
Impermanent loss calculator that shows if fees cover it
Most impermanent loss calculators are Uniswap-V2-only or get the V3 concentrated-liquidity math wrong — and almost none answer the question that actually decides your P&L: do trading fees cover the loss? ILCalc gets the math right for Uniswap V2, V3 (concentrated), and Balancer weighted pools. It shows an IL curve chart, a "vs just holding" comparison, and the break-even fee APR. Free, client-side, no wallet connect, no signup.
Hey Product Hunt 👋
As a liquidity provider I kept hitting the same problem: almost every impermanent loss calculator is either Uniswap-V2-only, quietly ignores trading fees, or — worse — prints wrong dollar figures for V3 concentrated positions. For an LP that's the difference between "this pool is fine" and "I'm slowly bleeding."
So I built ILCalc to get the math right, and to answer the one question that actually decides whether LPing was worth it: do the fees cover the impermanent loss?
It handles Uniswap V2, V3 concentrated liquidity, and Balancer weighted pools — with an IL curve, a "vs just holding" comparison, and the break-even fee APR. All client-side: no wallet connect, no signup. The math even runs a self-test on every load (add ?selftest=1) because correctness is the whole point.
It's free — I'd genuinely love your feedback, especially if you spot a number that looks off. Thanks for checking it out 🙏
how are you handling the V3 fee tier selection in the calculations, since that obviously changes the break-even APR a lot depending on whether someone picks the 0.05% or 1% pool?
Finally a calculator that actually shows the break-even fee APR — that's the number I always had to compute by hand before. V3 concentrated math looks solid from a quick test.
