How to calculate commute cost
Yearly = (round-trip miles ÷ MPG × gas price + parking) × work days
Worked example. Yearly commute cost: $938.
Example inputs — Distance one way (miles): 15; Time one way (minutes): 25; Days per week: 5; Fuel economy (MPG): 28; Gas price (per gallon): $3.50; Parking & tolls (per day): $0.00. Starting values are illustrative.

How it works
Based on 50 working weeks a year. Fuel is round-trip miles ÷ MPG × gas price. Wear and tear adds more — the IRS standard mileage rate reflects the full cost of driving.

Should I include car wear?
For a full picture, yes. Maintenance, tires and depreciation often exceed fuel costs.
