Model a MONSTA-to-WBNB constant-product trade from explicit reserves without presenting the result as a live executable quote.

Runs in this browser. No wallet, account, signature or transaction.
The calculator applies a selected token tax and pool fee to the nominal MONSTA input, then uses the constant-product reserve formula to estimate WBNB output. It reports average execution price and reserve-driven price impact separately. Every reserve is entered manually, so the result is a reproducible scenario rather than a live quote. Read the MONSTA liquidity guide to inspect the documented rule and its evidence boundary in more detail.
net input = MONSTA sold × (1 − token tax) × (1 − pool fee); WBNB out = WBNB reserve × net input ÷ (MONSTA reserve + net input)Selling 1,000,000 MONSTA into a modeled pool with 400,000,000 MONSTA and 1.1 WBNB produces a small WBNB output whose average price is below the initial reserve ratio. Raising trade size increases reserve-driven impact nonlinearly. Review fee-on-transfer execution risk before treating the modeled output as present contract behavior.
The selected transfer tax reduces nominal MONSTA before pool pricing.
The pool fee reduces the input used by the reserve equation.
Trade size changes the reserve ratio and average execution price.
A fee-on-transfer token sale cannot be explained with one “slippage” number. This model keeps the token deduction, automated-market-maker fee and reserve-driven impact separate so each assumption remains visible.

1 − average ÷ initial spotIsolates reserve-driven impact from the entered token tax.
A pair exposes two reserves, but their order only becomes meaningful after checking token0 and token1. Entering WBNB in the MONSTA field reverses the price and makes every downstream output meaningless. Preserve the pair address, observation block, token addresses and raw reserve integers before adjusting for decimals.
Reserve timestamps matter too. A mathematically correct calculation from an old reserve state is still an old scenario. It should be labeled with the observation time and never presented as a current executable price.
Record enough context for another researcher to rebuild the result without trusting the interface.
Verify the pair contract, token order and decimals. A ticker or interface label cannot establish which assets the reserves represent.
Record reserve0, reserve1 and the observation block. Do not combine one current reserve with another value copied from an older report.
Source the pool fee from the specific venue and the token tax from the implementation applicable to the modeled path. Defaults are starting hypotheses.
Compare several nominal inputs. Constant-product impact grows nonlinearly, so scaling a small-trade rate linearly understates a larger trade.
The initial price stays similar while the same trade becomes smaller relative to depth.
The reserve curve is nonlinear; average execution deteriorates as more WBNB leaves.
The pool-only impact can fall even while the seller’s total effective outcome worsens.

Answers about amm impact model, its inputs and the evidence limits specific to this result.
No. It is a constant-product scenario using the reserves and fees entered by the reader. Live execution can differ because reserves, routing, taxes, gas and ordering change.
They describe different deductions. The token contract may reduce the amount reaching the pair, while the automated market maker applies its own fee inside the swap calculation.
Enter the MONSTA quantity as the MONSTA reserve and the paired wrapped BNB quantity as the WBNB reserve. Confirm token0 and token1 on the pair contract before copying values.
It compares the modeled average pool execution price with the initial reserve ratio after isolating the entered token tax. It is not the total difference from an external market price.
No. A transaction minimum needs a fresh executable quote plus a deliberate tolerance. This page never creates transaction parameters or recommends a slippage setting.
