Model the original transfer-tax arithmetic without connecting a wallet or treating a historic rule as current contract state.

Runs in this browser. No wallet, account, signature or transaction.
The documented legacy model applied a 5% tax to a transfer: 2.5% went to supply reduction and 2.5% to a temporary-vault path. Enter any amount or rate to inspect that arithmetic. The result excludes liquidity-pool fees, gas, exemptions, price impact and later implementation changes. Read the sourced MONSTA tax-system guide to inspect the documented rule and its evidence boundary in more detail.
total tax = transfer amount × tax rate; recipient estimate = amount − total tax; each legacy half = total tax ÷ 2For 1,000,000 MONSTA at 5%, the model returns 950,000 MONSTA to the recipient, 25,000 MONSTA for the burn half and 25,000 MONSTA for the temporary-vault half. Understand fee-on-transfer token risk before treating the modeled output as present contract behavior.
The default recreates the original total transfer-tax description.
Half of the modeled tax represented supply reduction.
The other half represented the temporary-vault path.
The MONSTA tax calculator is a deterministic transfer model. It separates the amount entered, the recipient estimate and the two historic allocations so each number can be checked independently.
amount × (1 − rate)The tokens left after subtracting only the modeled token tax.
It is not the minimum received from a decentralized-exchange swap.
amount × rateThe gross quantity removed from the transfer amount by the selected rate.
It does not include gas, pool fees, routing costs or price impact.
tax ÷ 2The equal supply-reduction allocation described by the original model.
It does not prove tokens are currently sent to an irrecoverable address.
tax ÷ 2The equal temporary-vault allocation described in historic materials.
It does not prove a present reserve balance or holder entitlement.
A direct token transfer and a PancakeSwap trade answer different questions. This calculator applies one percentage to a nominal MONSTA amount. A swap travels through a liquidity pool and can also be affected by the pool fee, reserve depth, trade direction, routing, slippage settings and BNB Chain gas.
If a user enters 1,000,000 MONSTA at 5%, the 950,000 result means only “amount after modeled token tax.” It should never be relabeled as the number a buyer receives, the number a seller can cash out or the market value of either side.
Use the arithmetic as a prediction, then compare it with transaction-specific evidence. A disagreement is a reason to investigate the path, not to force the receipt into the old formula.
Determine whether the record is a wallet transfer, buy, sell, liquidity operation or contract-mediated movement. The same token can encounter different execution paths.
Record the transaction block and identify the implementation serving the documented proxy at that block. A proxy address can remain constant while delegated logic changes.
Read the sender and recipient token movements from the receipt. Check whether an exemption, router or pair address explains a result that differs from the selected percentage.
Account for pool output, price impact and gas separately. Combining all deductions into one “MONSTA tax” produces a number that cannot be reproduced.
On 1,000,000 MONSTA, the model assigns 5,000 to each historic half.
The model assigns 25,000 to the burn half and 25,000 to the vault half.
This is a sensitivity test, not a claim that the protocol documented a 10% standard rate.
Use the tax-system guide for the historic rule, then use the fee-on-transfer guide to understand why a token-level deduction can disrupt swap estimates and integrations.
Answers about legacy tax simulator, its inputs and the evidence limits specific to this result.
No. Five percent is the documented historic design used by this model. Current behavior must be tested against the active implementation, address exemptions and the exact transaction path.
No. It is arithmetic for a token transfer. A swap can also include pool fees, price impact, routing and gas.
No. It runs locally in the browser and neither requests an address nor asks for a signature.
The original Cake Monster model described equal burn and temporary-vault allocations. The equal split is a historic modeling assumption, not evidence of current destination addresses or balances.
Record the transaction block, identify the implementation active at that block and compare token balance changes and transfer logs. Keep pool output, gas and routing costs separate from the token-level deduction.
