quick answer

What is impermanent loss?

The difference between the value of tokens in a liquidity pool and the value the same tokens would have if you had held them, caused by the pool rebalancing as prices move.

how to use the impermanent loss calculator

Impermanent loss is what a liquidity provider gives up compared with just holding the two tokens. Enter each token's price change, your deposit and the pool's fee APR to see the loss, the LP position against holding, and how long fees take to make up the difference.

Enter your deposit
Enter the value you deposit into the pool.
Enter the price moves
Enter the price change of each token since you deposited (e.g. the memecoin +200%, SOL 0%).
Add fees and time
Enter the pool's fee APR and the days you stay in.
Compare LP vs hold
Compare the LP value with the value of simply holding.

formula

The exact math the impermanent loss calculator runs, so you can check any result by hand.

r = (1 + change A) ÷ (1 + change B)impermanent loss = 2 × √r ÷ (1 + r) − 1LP value = hold value × (1 + impermanent loss) + fees

guide

impermanent loss by price change

1.25x ratio change: −0.6%
1.5x: −2.0%
2x: −5.7%
3x: −13.4%
5x: −25.5%
10x: −42.5%
0.5x (one side halves): −5.7%

The loss depends only on how far the two prices drift apart, not on direction. It is "impermanent" because it disappears if the ratio returns to where you entered, and becomes permanent when you withdraw.

memecoin pools are the extreme case

Providing liquidity to a memecoin/SOL pool means the pool sells your memecoin as it pumps and buys more of it as it dumps. If the memecoin does a 10x you keep about 57% of what holding would have given; if it goes to zero you end with the whole position in the dead token's side draining toward zero. High fee APRs on these pools pay for exactly that risk.

frequently asked questions

How much impermanent loss is there at 2x?

5.72% versus holding, for a 50/50 constant-product pool, whether one token doubles or the other halves.

Can fees cover impermanent loss?

Yes, if the pool earns enough trading fees before you withdraw. The calculator shows the number of days at your fee APR needed to break even with holding.
