Free Impermanent Loss Calculator

Calculate impermanent loss (IL) for Solana and Uniswap liquidity pools — free, no signup, runs in your browser. Includes a live pool inspector, Monte-Carlo IL simulator, Sharpe ratio, LP excess return vs. HODL, and net APR.

What is impermanent loss?

Impermanent loss is the gap between holding two tokens in an AMM liquidity pool versus holding them in your wallet. When the price ratio shifts, the pool rebalances automatically, leaving you with less of the appreciating token. The classic constant-product formula is IL = 2·√r / (1 + r) − 1, where r is the new-to-old price ratio.

Why use this calculator?

• Plug in token A and token B prices — both current and projected — and see IL instantly.
• Load any Solana pool and run a 5,000-path Monte-Carlo simulation.
• Compare LP returns vs. a HODL baseline, with Sharpe and net APR.
• 100% client-side. No wallet connection required.

FAQ

How is impermanent loss calculated?

For a 50/50 constant-product pool, IL = 2·√r/(1+r) − 1, where r is the price-ratio change. A 2× move gives ~5.7% IL; a 5× move gives ~25%.

Does this work for Uniswap V3?

The base formula applies to V2-style AMMs. For Uniswap V3 concentrated liquidity, IL is amplified by your range's leverage factor — the simulator estimates net outcomes across many price paths.

Is it really free?

Yes. The TraderBear impermanent loss calculator is free, runs entirely in your browser, and does not require signup or a wallet.
