Weekly Fuel Cost Calculator Formula
The formula is Weekly Cost = (Weekly Miles ÷ MPG) × Fuel Price.
Weekly Cost = (Weekly Miles ÷ MPG) × Fuel PriceFormula variables
- Weekly Miles
- All miles driven from Monday to Sunday.
- MPG
- Combined fuel economy.
- Fuel Price
- Dollars per US gallon (3.785 L).
Worked example
- Weekly Miles: 250 miles
- Vehicle MPG: 28 MPG
- Fuel Price: $3.65/gal
- Gallons per week: 250 ÷ 28 = 8.93 gallons (33.8 L).
- Weekly cost: 8.93 × $3.65 = $32.59.
Result: $32.59 ($/week)
A weekly cost of $32.59 equals $1,694.64 over 52 weeks. Reading the odometer every Sunday gives an accurate weekly miles figure.
