How It Works
How to Calculate Commute Costs
A daily commute has fuel costs (distance / MPG x price) plus tolls. Multiply by workdays for monthly and annual totals.
Formula
Daily Fuel = (Round-Trip Miles / MPG) x Fuel Price
Monthly Cost = (Daily Fuel + Tolls) x Workdays
Worked Example
22-mile each way commute, 28 MPG, $3.50/gal, no tolls, 22 workdays.
- 01Daily round trip = 22 x 2 = 44 miles
- 02Daily fuel = 44 / 28 x $3.50 = $5.50
- 03Monthly cost = $5.50 x 22 = $121.00
- 04Annual cost = $121.00 x 12 = $1,452.00
Frequently Asked Questions
What costs does this not include?
This covers fuel and tolls. Full commute costs also include vehicle depreciation, maintenance, insurance, parking fees, and the opportunity cost of your time.
How does commute cost compare to remote work?
Add up annual commute costs, parking, and work clothes. If the total is significant, remote work even a few days per week can save thousands per year.
How do I reduce commute costs?
Carpool, use public transit, work remotely when possible, maintain proper tire pressure for better MPG, and combine errands to reduce extra trips.
