Before submission
Known: selected gas limit and proposed gas price.
Calculated: maximum BNB that could be charged under those values.
Unknown: actual path, state-dependent work and whether execution succeeds.

How Transaction cost model works
The calculator multiplies gas limit by gas price and converts gwei to BNB. An optional manually entered BNB/USD reference produces an illustrative fiat equivalent. The gas limit is a ceiling: a successful transaction may consume less, while a reverted transaction can still consume gas. Read the BNB Chain gas guide to inspect the documented rule and its evidence boundary in more detail.
Transaction cost model equation
maximum gas cost in BNB = gas limit × gas price in gwei ÷ 1,000,000,000; USD estimate = BNB cost × entered BNB/USD priceTransaction cost model example
A 200,000 gas limit at 3 gwei gives a maximum network cost of 0.0006 BNB. At a manually entered $600 per BNB, that equals $0.36 before token taxes or traded value. Learn to verify transaction receipts before treating the modeled output as present contract behavior.
Network-cost equation
Gas limit
Maximum execution units made available to the call.
Gas price
BNB-denominated price per unit, entered in gwei.
Actual gas used
Receipt value needed to replace the pre-transaction ceiling with final cost.
SEPARATE THE CEILING
FROM THE RECEIPT.
Before submission, gas limit multiplied by gas price provides a maximum network budget. After execution, actual gas used is the value that belongs in a transaction-cost report.
After confirmation
Known: receipt status, gas used and effective gas price.
Calculated: final BNB network cost.
Still separate: token tax, swap output, price impact and allowance exposure.
Why a revert can still cost BNB
A reverted transaction rolls back its state changes, but validators still processed instructions until the failure. Gas accounts for that computation. The receipt can therefore show no successful MONSTA transfer while the sender’s BNB balance still falls.
Failure investigation should record the revert reason, method, gas used and whether the limit was exhausted. Increasing the gas limit only helps when the call ran out of gas; it does not repair a failing condition, missing permission or unsuitable transaction path.

Status
Did the state transition succeed?
A failed status can still have a nonzero network cost.
Whether an interface displayed a success message.
Gas used
How many execution units were consumed?
Multiply by effective gas price for final BNB cost.
The submitted gas limit.
Effective gas price
What price applied to each consumed unit?
Use the receipt value when reconstructing actual cost.
MONSTA price or token tax rate.
Logs
Which events did successful execution emit?
Token transfer logs help reconstruct movement and deductions.
Proof that every event description is truthful or safe.
Limit doubles
Ceiling doublesActual cost stays unchanged if gas used and effective price do not change.
Gas price doubles
Cost doublesBoth the preflight ceiling and final cost scale linearly with unit price.
Call reverts early
Partial gas consumedNo intended state change occurs, but computation before the revert remains chargeable.

BNB CHAIN GAS CALCULATOR FAQ.
Answers about transaction cost model, its inputs and the evidence limits specific to this result.
01Is gas limit the amount I will definitely pay for?
No. It caps the gas units available. The receipt records actual gas used; unused gas is not charged as if it had been consumed.
02Why can a failed transaction still cost BNB?
Validators performed computation before the state change reverted. The token movement may fail while the network work remains chargeable.
03Does this include the MONSTA transfer tax?
No. Gas is paid in BNB to execute the transaction. Token-level deductions and automated-market-maker effects are separate.
04Where should the gas price come from?
Use a current wallet or BNB Chain fee estimate and record when it was observed. The calculator does not fetch or silently substitute a live value.
05Why is the USD result optional?
Network settlement uses BNB. The fiat figure depends on a separate price observation, so leaving it blank preserves the primary BNB calculation.
