Use a minus sign for a fall, such as -30. Covers 50/50 pools on constant-product exchanges and leaves out trading fees and rewards. This is a calculator, not advice.
What impermanent loss is
When you add two tokens to a 50/50 liquidity pool, the pool keeps rebalancing as traders swap. If one token's price moves against the other, you end up holding more of the one that fell and less of the one that rose. Compared with just holding the tokens, your share is worth less: that gap is impermanent loss.
Why it is called impermanent
The loss only depends on where prices are compared with when you joined. If prices return to where they started, it disappears; if you withdraw while they are apart, it becomes real. Trading fees earned by the pool can make up some or all of it, which this calculator leaves out.
