How to Use the AMM Calculator

01Enter Pool ReservesInput the current liquidity pool reserves for Token A and Token B — these represent the total locked value in the AMM contract. You can get these values from on-chain data or DEX analytics dashboards (e.g., Dextools, Etherscan). The reserves define the pool's liquidity depth: larger reserves mean less slippage for the same trade size. Name the tokens to make the results easier to read.

02Enter Swap AmountEnter the amount of Token A you want to swap. The calculator uses the constant-product formula (x × y = k) where x and y are the reserves and k remains invariant. A 0.3% fee is deducted from your input before the swap: the effective input becomes amountIn × 0.997, which goes into the pool, and the output is calculated from the new reserve ratio. This fee is distributed to liquidity providers as their reward.

03Review Output & Price ImpactThe results show your expected output of Token B, the spot price (current market rate = reserveA/reserveB), your execution price (what you actually pay = amountIn/amountOut), and the price impact percentage. Price impact measures how much your trade moves the market — it's calculated as (amountIn / (reserveA + amountIn)) × 100. Price impact above 2% is considered high slippage — consider splitting your trade into smaller chunks to get a better average price.

About AMM Price Calculator

Simulates constant-product AMM (x × y = k) swap mechanics used by Uniswap V2 and similar DEXs. The constant-product invariant ensures that the product of the two reserves always stays constant (ignoring fees). When you swap token A for token B, the pool takes your input, deducts a 0.3% fee (which increases k slightly), and calculates the output using the formula: amountOut = (amountIn × 0.997 × reserveB) / (reserveA + amountIn × 0.997). The model accounts for the standard 0.3% trading fee deducted from each swap and calculates both the spot price (current market rate) and your effective execution price after slippage. Price impact represents the percentage deviation between these two prices.

When to use it

Use this tool to estimate swap output before executing a trade on a Uniswap V2-style DEX, understand how much slippage a trade would cause, simulate the impact of large trades against a pool, or compare expected execution prices across different pool sizes.

Tips & Tricks

•Price impact above 2% is considered high slippage — consider splitting large trades into smaller amounts over time or using a DEX aggregator.
•Larger pool reserves mean lower price impact for the same trade size — always check pool depth before trading large amounts.
•Uniswap V3 concentrated liquidity behaves differently within tick ranges — this V2 calculator assumes full-range liquidity.
•The 0.3% fee is built into the constant-product formula — you do not see it as a separate line item but it reduces your output.
•For very large trades, the execution price can deviate significantly from the spot price — always compare both before confirming.
