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
计算示例
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
常见问题
Is a 10 MPG improvement always worth it?
The value depends on your starting point. Going from 15 to 25 MPG saves much more fuel than going from 35 to 45 MPG for the same miles driven.
Should fuel cost be the only factor when choosing a car?
No. Consider purchase price difference, insurance, maintenance, reliability, comfort, and resale value alongside fuel economy.
How many miles does the average American drive?
About 13,500 miles per year, or roughly 37 miles per day.
