How it works
Annual Fuel Cost Calculator: inputs, formula, and result
Enter the values that describe your supporting scenario. The interactive result changes as the inputs change, helping you compare fuel efficiency, fuel consumption, fuel cost, or operating impact.
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.
