Helps liquidity providers estimate potential impermanent loss when providing liquidity to decentralized finance pools. Useful for DeFi investors analyzing risk in liquidity mining. Input current and initial prices to see the impact on your returns.

How to Use This Tool
Enter the initial and current prices of both assets in the liquidity pool. If you want to see the dollar impact, provide your initial investment amount. The calculator assumes you deposited equal value in both assets at the initial prices, which is typical for most liquidity pools.
Formula and Logic
The impermanent loss is calculated based on the change in the price ratio between the two assets. The key formula is:
IL% = [1 - (2 * √P) / (1 + P)] × 100
where P = (current price ratio) / (initial price ratio) = (pA/pB) / (pA0/pB0).
If an initial investment is provided, the calculator also computes the holding value and pool value assuming equal initial allocation.
Practical Notes
Impermanent loss is a key risk in automated market maker (AMM) protocols. It occurs when the prices of assets in a liquidity pool diverge from their initial ratios. While "impermanent," the loss becomes permanent if you withdraw after the price change. Consider the following:
- Risk vs. Return: Liquidity providers earn trading fees, which can offset impermanent loss. Always compare expected fees against potential IL.
- Diversification: Providing liquidity for correlated assets (e.g., stablecoin pairs) minimizes IL. Volatile asset pairs carry higher IL risk.
- Compounding Effects: Reinvesting fees can help mitigate IL over time, but does not eliminate the underlying price risk.
- Market Volatility: In highly volatile markets, IL can be substantial. Use this tool to simulate worst-case scenarios before committing capital.
Why This Tool Is Useful
For DeFi investors, understanding impermanent loss is crucial for making informed decisions about liquidity provision. This calculator provides a quick, quantitative estimate of potential loss, helping you weigh the trade-offs between fee income and price risk. It's valuable for portfolio managers assessing the impact of liquidity mining on overall returns.
Frequently Asked Questions
What is impermanent loss?
Impermanent loss is the difference in value between holding assets separately and providing them as liquidity in an AMM pool. It occurs when the relative prices of the assets change after deposit.
How can I avoid impermanent loss?
You cannot completely avoid impermanent loss, but you can minimize it by choosing pools with correlated assets (e.g., stablecoins), providing liquidity for shorter periods, or using protocols with IL protection. Always factor in earned fees.
Is impermanent loss permanent?
The loss is "impermanent" as long as you don't withdraw; if prices return to the initial ratio, the loss disappears. However, if you withdraw when prices have changed, the loss becomes permanent. In practice, many LPs experience permanent IL due to sustained price divergences.
Additional Guidance
When using this calculator, input accurate current prices from reliable sources. Remember that this tool assumes a constant product AMM like Uniswap V2; other AMM models may have different IL characteristics. For large positions, consider the impact of your own trades on pool prices. Always conduct thorough due diligence before investing in liquidity pools.
