How it works
Annual Fuel Cost Calculator: inputs, formula, and result
By taking your vehicle's average MPG, multiplying it by your expected yearly mileage, and applying the average local cost of fuel, this tool predicts your annual spending. It provides a straightforward forecast of your out-of-pocket expenses for the entire year.
Formula
Annual Fuel Cost = (Annual Miles ÷ MPG) × Fuel Price
Worked example
12,000 miles/year at 30 MPG with gas at $3.50/gallon costs (12000 ÷ 30) × 3.50 = $1,400/year.
Pro tip: Use this when comparing vehicles to buy. A 10 MPG difference (20 vs. 30 MPG) at 12,000 miles/year equals $700/year, or $3,500 over 5 years.
