How to Compare Fuel Efficiency
Calculate each vehicle's annual fuel cost and find the difference.
Formula
Annual Fuel Cost = Annual Miles / MPG x Gas Price
Savings = Cost A - Cost B
Example Calculation
12,000 miles/year at $3.50/gal: Vehicle A gets 25 MPG, Vehicle B gets 35 MPG.
- 01Vehicle A cost = 12,000 / 25 x $3.50 = $1,680
- 02Vehicle B cost = 12,000 / 35 x $3.50 = $1,200
- 03Annual savings = $1,680 - $1,200 = $480
- 045-year savings = $480 x 5 = $2,400
