Launch Slippage Calculator →Purpose
Make slippage tangible before you set tolerance on a DEX or size a market order on a thin book.
When to use it
- Before a large swap on an AMM
- When a pair looks illiquid
- To educate someone on why size moves price
- Alongside fee breakeven for round-trips
How to use it
- Enter expected price and size context. Use the tool inputs for your scenario.
- Review estimated impact. Read how far the effective price may move.
- Set wallet tolerance carefully. High tolerance avoids reverts but can accept bad fills.
- Check gas. Failed swaps still cost gas — time the network too.
Benefits
- Forces size-vs-liquidity thinking
- Pairs with gas and fee tools
- Free educational calc
- Helps set sane tolerances
Pitfalls to avoid
- Real pools and order books differ from simple models
- MEV can worsen effective price
- Stablecoin depegs add another error term
- Estimate only
Liquidity is not market cap
A large-cap asset can still be costly to trade on a quiet pool. Estimate slippage, then confirm with a simulation on the DEX UI.
