# Slippage Calculation (for Uniswap V2 and its forks)

> To predict the amount of tokens required to reach a specified slippage, you can use `Pool Slippage` endpoint. It works for any pool that exists on Uniswap V2 or any fork DEX on supported list of exchanges.

The logic is as follows:

Provide the address of the pool, select a token in which you wish to have slippage calculated (e.g. if selected ETH from ETH-USDC, it will show how much is ETH is required to move the price by selected amount) and determine the goal for price movement.
