How Gasoline Fuel Budget Calculator Works
This tool works by pricing gasoline consumption at the pump price of the chosen grade and converting between US gallons, imperial gallons, and liters.
- Step 1
Enter driving distance
Type the miles or kilometers for the budget period.
- Step 2
Enter gasoline fuel economy
Use the combined MPG or L/100 km of the gasoline engine.
- Step 3
Choose the gasoline grade
Enter the price for regular (87 octane), midgrade (89), or premium (91 to 93).
- Step 4
Read the gasoline budget
The calculator shows gallons, liters, total cost, and cost per 100 miles or 100 km.
Gasoline Fuel Budget Calculator Formula
The formula divides distance by MPG and multiplies by the gasoline price.
Gasoline Budget = (Distance ÷ MPG) × Gasoline Price per Gallon
Price per Liter = Price per US Gallon ÷ 3.785
- Gasoline Price
- = pump price for the chosen octane grade
- 3.785
- = liters in one US gallon
Worked Example
- A driver budgets 1,200 miles (1,931 km) per month in a 28 MPG (8.4 L/100 km) sedan on regular gasoline.
- Gasoline used = 1,200 ÷ 28 = 42.9 gallons (162.2 liters).
- Gasoline budget at $3.45 per gallon ($0.911 per liter) = $147.86 per month.
- Cost per 100 miles = $12.32.
Gasoline Fuel Budget Calculator Conversion Table
The table converts gasoline prices between US gallons, liters, and imperial gallons, with cost per 100 miles at 28 MPG and per 100 km at 8.4 L/100 km.
| Price / US gal | Price / L | Price / Imperial gal | Cost / 100 mi (28 MPG) | Cost / 100 km (8.4 L) |
|---|---|---|---|---|
| $2.50 | $0.660 | $3.00 | $8.93 | $5.55 |
| $3.00 | $0.793 | $3.60 | $10.71 | $6.66 |
| $3.25 | $0.859 | $3.90 | $11.61 | $7.21 |
| $3.50 | $0.925 | $4.20 | $12.50 | $7.77 |
| $3.75 | $0.991 | $4.50 | $13.39 | $8.32 |
| $4.00 | $1.057 | $4.80 | $14.29 | $8.88 |
| $4.50 | $1.189 | $5.40 | $16.07 | $9.99 |
| $5.00 | $1.321 | $6.00 | $17.86 | $11.10 |
What is a Gasoline Fuel Budget Calculator?
A Gasoline Fuel Budget Calculator is a budgeting tool that uses gasoline prices and gasoline fuel economy to estimate driving costs.
Gasoline fuels about 9 in 10 light vehicles on US roads. Prices change by grade, region, and season, and the price unit changes by country: US gallons in the United States, liters in Canada and Europe, and imperial gallons in some UK references. The Gasoline Fuel Budget Calculator handles all 3 units.
Drivers enter the grade the owner’s manual requires. Using premium in a car designed for regular gasoline adds cost with no fuel economy gain.
What are the uses of a Gasoline Fuel Budget Calculator?
There are 4 main uses of the Gasoline Fuel Budget Calculator, including monthly budgets, grade cost checks, and cross-border price conversion.
