How Annual Gas Budget Calculator Works
This tool works by projecting 12 months of driving into one yearly fuel volume and pricing that volume at an average annual gas price.
- Step 1
Enter annual mileage
Use the odometer reading from the last 12 months or multiply weekly miles by 52. The average US driver covers about 13,500 miles (21,700 km) per year.
- Step 2
Enter fuel economy
Type the combined miles per gallon (MPG) or liters per 100 kilometers (L/100 km) figure.
- Step 3
Enter an average price
Use an average price for the year, not the price on one day.
- Step 4
Read the annual budget
The calculator shows annual fuel volume, annual cost, and the monthly average.
Annual Gas Budget Calculator Formula
The formula divides annual miles by MPG and multiplies the result by the average price per gallon.
Annual Gallons = Annual Miles ÷ MPG
Annual Gas Budget = Annual Gallons × Average Price per Gallon
Monthly Average = Annual Gas Budget ÷ 12
- Annual Miles
- = total distance driven in 12 months
- Average Price
- = expected mean fuel price across the year
Worked Example
- A driver covers 13,500 miles (21,726 km) per year in a 26 MPG (9.0 L/100 km) sedan.
- Annual fuel = 13,500 ÷ 26 = 519.2 gallons (1,965 liters).
- Annual gas budget at $3.55 per gallon = $1,843.27.
- Monthly average = $1,843.27 ÷ 12 = $153.61.
Annual Gas Budget Calculator Conversion Table
The table shows yearly fuel cost for a 26 MPG vehicle across annual mileage levels and 3 average gas prices.

What is an Annual Gas Budget Calculator?
An Annual Gas Budget Calculator is a long-range planning tool that projects 12 months of fuel spending from yearly mileage, fuel economy, and an average price.
Annual fuel costs for US drivers fall between $1,200 and $3,500 for most cars and light trucks. That range makes fuel one of the 3 largest vehicle costs, next to depreciation and insurance. The Annual Gas Budget Calculator shows where a driver sits in that range.
A yearly figure smooths out summer price peaks and winter dips. The figure suits total cost of ownership comparisons, tax planning, and savings goals.
What are the uses of an Annual Gas Budget Calculator?
There are 5 main uses of the Annual Gas Budget Calculator, including ownership cost comparison, savings goals, and lease mileage checks.
