Slippage, price impact and fees are three different costs

Price impact is the effect order size has on price within available liquidity. Slippage tolerance is the adverse movement permitted between quote and execution. Network, platform and provider fees are separate costs.

A larger tolerance can help a transaction complete in a fast market, but it also allows a worse result. It does not fix shallow liquidity.

Before signing, compare input, estimated output, minimum received, price impact, every fee and quote expiry. Request a new quote after expiry.
