How this calculator works
01
Transaction presets supply approximate gas-unit starting points; you can overwrite every value.
02
Wei and Gwei are converted with arbitrary-precision decimal arithmetic, avoiding floating-point rounding errors.
03
The USD result is derived from the price you enter and is never presented as a live market quote.
Formula
The calculation
Network cost = gas units × gas price; USD cost = native-token cost × native-token USD priceExample
A concrete scenario
An ERC-20 transfer using 65,000 gas at 2 Gwei costs 0.00013 native tokens. At $3,000 per token, that is $0.39.
