How efficiency becomes a cash difference
Annual gallons equal miles divided by MPG. The tool prices those gallons for each vehicle, then divides the extra purchase cost by annual fuel saving for a simple break-even.
Driving conditions that change the result
Run several fuel prices and real-world efficiency estimates. Financing, insurance, maintenance and resale can outweigh fuel savings.
