Estimate fuel needed and trip fuel cost using US MPG or metric litres per 100 kilometres.
A 300-mile trip at 30 MPG uses 10 gallons.
The calculator keeps each component visible so you can review inputs instead of relying on one unexplained total.
Estimate fuel needed and trip fuel cost using US MPG or metric litres per 100 kilometres. It can help employees, shift workers, freelancers, supervisors and small-business owners make quick planning estimates before reviewing an official time card or payroll statement.
Results can be formatted for USD, GBP, CAD, AUD, EUR or NZD when money is involved. Currency formatting does not apply tax, minimum-wage, overtime or employment-law rules automatically.
Enter the requested values and select Calculate. The tool applies this method: US mode uses distance ÷ MPG; metric mode uses distance × L/100 km ÷ 100.
The result is a planning estimate. Employer policies, contracts, taxes and employment laws can change the final amount.
No account is required. Calculator values are processed in your browser and are not saved to a payroll database by this site.
