Estimate slippage for your crypto market orders based on order size and market liquidity. Calculate the real cost of large orders including price impact.
Slippage is the difference between the expected trade price and the actual execution price. It occurs because market orders need to be filled against multiple limit orders at progressively worse prices. Larger orders relative to available liquidity experience more slippage.
In crypto, slippage can be significant — especially for altcoins with thin order books, during volatile periods, or when trading large positions. A $100,000 market order in a thin market might experience 0.5-2% slippage, costing $500-2,000 more than the displayed price.
This calculator estimates slippage based on your order size and the market's available liquidity within a price range. It helps you understand the true execution cost of market orders and determine whether splitting an order or using limit orders would be more cost-effective.
Crypto traders, long-term holders, and DeFi participants benefit from transparent crypto slippage calculations when planning entries, exits, or portfolio rebalances. Revisit this calculator whenever market conditions shift to keep your strategy grounded in accurate data.
Displayed prices on exchanges show the best available price, but only for a small quantity. Your actual fill price depends on how deep your order goes into the order book. This calculator estimates the price impact so you can factor slippage into your trade planning and decide on execution strategy.
Estimated Slippage % = (Order Size / Available Liquidity) × Base Impact Factor Slippage Cost = Order Size × Slippage % Effective Price (buy) = Mid Price × (1 + Slippage %) Effective Price (sell) = Mid Price × (1 − Slippage %)
Result: Estimated Slippage: 0.20% | Cost: $200
A $100,000 order in a market with $500,000 liquidity within 0.5%: the order consumes 20% of near-price liquidity. Estimated slippage is approximately 0.20%, costing an extra $200. Your effective buy price would be $65,130 instead of $65,000.
Slippage is directly related to order book depth — the total quantity available at prices near the current market. Deep books (lots of resting orders at many price levels) absorb large orders with minimal slippage. Thin books (sparse orders, wide gaps) cause significant slippage even for moderate-sized orders. BTC/USDT on Binance has among the deepest crypto order books, while small-cap altcoins may have virtually no depth.
During volatile periods, slippage increases because: market makers widen their quotes, other traders cancel their resting orders, and many participants try to execute simultaneously. Flash crashes often feature extreme slippage where orders fill at prices far from the pre-crash level. This is why stop-loss orders sometimes fill at much worse prices than the stop price.
Institutional traders use sophisticated execution algorithms: TWAP splits orders evenly over time, VWAP weights execution toward high-volume periods, Iceberg orders hide the true order size, and dark pools match large orders privately. While these aren't all available to retail traders, understanding them helps you appreciate the slippage problem and develop your own mitigation strategies.
Slippage occurs because the order book has limited quantity at each price level. A market buy order starts filling at the best ask price, but once that quantity is exhausted, it moves to the next price level, then the next, resulting in an average fill price above the initial displayed price.
For BTC and ETH on major exchanges with normal-sized orders ($1,000-$10,000), slippage is typically 0.01-0.05%. For $100,000+ orders, 0.05-0.2%. For altcoins with thin books, slippage can be 0.5-5% even for moderate orders. During extreme volatility, slippage can spike for all assets.
Use limit orders (zero slippage but uncertain fill). Split large orders into smaller pieces over time. Trade during high-liquidity hours. Use exchanges with deeper order books. Consider OTC desks for very large orders ($100K+). Use iceberg orders to hide order size.
It can be worse in either direction depending on order book imbalance. If there's more liquidity on the bid side, sells experience less slippage. If ask-side liquidity is deeper, buys fill better. Check both sides of the book before large trades.
The spread is the difference between the best bid and best ask — it's the cost of crossing from one side to the other. Slippage is the additional cost beyond the spread caused by consuming multiple price levels. Total execution cost = half spread + slippage + fees.
No. Limit orders execute at exactly the specified price or better. This is why limit orders have zero slippage. The trade-off is that limit orders may not fill at all if the market doesn't reach your price. You exchange execution certainty for price certainty.
