Calculate Fuel Efficiency Comparison Calculator
How It's Calculated
Annual Cost = (Annual Miles ÷ MPG) × Fuel Price
Annual Diff = |Cost 1 − Cost 2|
5-Year Diff = Annual Diff × 5
Examples
25 MPG vs 35 MPG, 12,000 mi/yr, $3.50/gal $1,680 vs $1,200 → Save $480/yr ($2,400 over 5 years)
18 MPG vs 32 MPG, 15,000 mi/yr, $4.00/gal $3,333 vs $1,875 → Save $1,458/yr ($7,290 over 5 years)
