Impermanent Loss Calculator

What Impermanent Loss Calculator does

Providing liquidity to a DeFi pool exposes you to impermanent loss — the gap between what your position is worth in the pool versus what it would be worth if you'd simply held both assets outright. This tool takes the token's price when you deposited and its price now, and calculates that loss as both a percentage and, optionally, a dollar estimate.

How to calculate impermanent loss

Enter the token price at the time you deposited into the pool.
Enter the token's current price.
Optionally enter the amount you deposited, in USD, to see a dollar estimate alongside the percentage.

What impermanent loss actually measures

This compares a 50/50 liquidity pool position against simply holding both assets outside the pool — it is specifically the effect of price divergence on your pooled position, nothing else. It does not include trading fees earned from providing liquidity, which can partially or fully offset the loss, sometimes making the pool position more profitable overall despite a real impermanent loss figure.

Why "impermanent" can be misleading

The loss is only impermanent in the sense that it disappears if the price ratio returns to where it was when you deposited. If you withdraw while prices have diverged, the loss becomes permanent and realized — the name describes a mathematical property of the position, not a guarantee that the loss will reverse.

Ofte stillede spørgsmål

Does this include the trading fees I've earned from the pool?

No — it isolates the impermanent loss effect specifically. Fees earned need to be tracked separately and can offset some or all of the calculated loss.

Is impermanent loss always a bad outcome?

Not necessarily — if the fees earned from providing liquidity exceed the impermanent loss, the position can still be more profitable than simply holding. The calculator only shows one side of that equation.

Does this work for pools that aren't 50/50?

The standard calculation here assumes an even 50/50 pool, the most common structure. Pools with a different weighting will have a different loss profile that this simple calculation won't capture precisely.

What happens if I withdraw before prices diverge further?

The loss is only locked in — made permanent — at the moment you withdraw. If you don't withdraw and prices move back toward your deposit ratio, the loss shrinks or disappears.

Why is the dollar amount field optional?

The percentage loss is calculated from the price change alone; the dollar amount is only needed if you also want to see the estimated dollar impact on your specific deposit size.
