Slippage Calculator

WHAT IT DOES

Slippage Calculator is a DeFi tool that estimates the price impact and slippage for token orders. Enter the token price, order size, liquidity pool size, and slippage tolerance — the tool calculates the estimated price impact (as a percentage of the order relative to the pool), the estimated slippage (price impact + market volatility), and displays a status indicating whether the order is safe or has high slippage. It shows a visual slippage level bar (Low, Medium, High) with color-coded badges. This is essential for traders evaluating order execution, developers testing slippage scenarios, or anyone understanding how slippage affects trades.

HOW TO USE

Connect your wallet using the BGWallet bridge (MetaMask or any Web3 wallet). Enter the token price in USD — this is the current market price. Enter the order size in tokens — the amount you want to trade. Enter the liquidity pool size in USD — the total liquidity available in the pool. Enter your slippage tolerance as a percentage — this is the maximum slippage you are willing to accept. Click "Calculate slippage" to compute the results. The tool displays the token price, order size, pool liquidity, price impact, estimated slippage, slippage tolerance, and a status (Safe or High slippage). A visual bar shows the slippage level with a color-coded badge (Low, Medium, High). This is useful for understanding the potential cost of a trade before executing it.

TECHNICAL MECHANISM

The tool calculates price impact using the formula: priceImpact = (orderSize / (poolSize + orderSize)) × 100. This approximates the percentage change in price caused by the order relative to the pool's liquidity. Slippage is calculated as priceImpact + marketVolatility, where marketVolatility is a random factor (0.05-0.3%) simulating market conditions. The slippage is compared to the user's tolerance to determine the status (Safe if slippage ≤ tolerance, otherwise High slippage). The slippage level is categorized as Low (≤0.5%), Medium (0.5-1.5%), or High (>1.5%), with corresponding color-coded badges. The bar width is calculated as slippage × 10, capped at 100%. All calculations are performed client-side — no data is stored or transmitted. The tool is read-only and does not sign any transactions.

WHAT IT CANNOT SEE

The tool cannot fetch real-time liquidity pool data without external API or on-chain data feed — the pool size must be entered manually. It cannot account for price impact from large orders accurately without actual pool data — the calculation uses a simplified model. It cannot predict slippage for tokens with low liquidity — the model assumes a constant pool size. It cannot guarantee slippage calculations against actual market conditions — the volatility factor is randomized. It cannot handle tokens with transfer fees or rebasing mechanisms accurately — the calculation assumes standard ERC-20 tokens. It cannot account for order book depth or other market factors. The tool is read-only and does not sign any transactions.

PLEASE NOTE

This tool works exclusively with EVM-compatible chains for the wallet connection, but the slippage calculation is chain-agnostic. Solana, Tron, Starknet, SUI, TON, Aptos, Bitcoin, Cosmos, and XRP are not supported for wallet connection but the calculation works regardless. The tool provides estimates — actual slippage may vary based on market conditions. The tool does not store any data — all operations are performed client-side. The tool is provided as-is with no warranty or liability. Always verify slippage with real market data before executing trades.
