How to Use This Calculator
- Enter the total distance in miles (or km).
- Enter your vehicle's fuel efficiency (MPG or L/100km).

- For mileage reimbursement: enter the reimbursement rate per mile (2024 IRS rate: $0.67/mile).
- Click Calculate.
Mileage Formulas
Fuel Used = Miles ÷ MPG
Fuel Cost = Fuel Used × Gas Price Per Gallon
Mileage Reimbursement = Total Miles × Reimbursement Rate
Example Calculations
Road trip: 500 miles | 28 MPG | $3.50/gal
- Fuel = 500 ÷ 28 = 17.86 gallons
- Cost = 17.86 × $3.50 = $62.50
Business reimbursement: 1,200 miles driven for work in 2024
- Reimbursement = 1,200 × $0.67 = $804.00
IRS Standard Mileage Rates
- 2024: $0.67 per mile (business)
- 2023: $0.655 per mile (business)
- Medical/moving: $0.21 per mile (2024)
- Charitable: $0.14 per mile (2024)
Why Use This Calculator?
Trip planning requires knowing the real cost upfront — not just gas, but potentially parking, tolls, and meals. For employees, accurate mileage tracking is essential for proper reimbursement and tax deductions. This calculator covers all scenarios.
Common Mistakes to Avoid
- Forgetting round-trip distance — many people calculate one-way and forget to double it for the return journey.
- Using EPA highway MPG for city driving — use the combined MPG for mixed or city driving; highway MPG overstates real-world efficiency in urban conditions.
- Not logging business miles contemporaneously — the IRS requires contemporaneous mileage logs for business deductions. Track miles immediately, not from memory at year-end.
