How this calculator works
See what one workday of driving really costs in fuel—and optionally wear—before you commit to five days in the office. Fuel cost = (miles ÷ MPG) × gas price; total workday cost = fuel + (miles × wear). Example: A 30-mile round trip at 28 MPG and $3.89/gal costs about $4.17 in fuel, plus $3.00 wear at $0.10/mi → ~$7.17 per workday.
Fuel cost = (miles ÷ MPG) × gas price; total workday cost = fuel + (miles × wear).
Example: A 30-mile round trip at 28 MPG and $3.89/gal costs about $4.17 in fuel, plus $3.00 wear at $0.10/mi → ~$7.17 per workday.
When to use this Car Commute Cost Per Workday
Common use cases
- Estimate the fuel (and optional wear) cost of a round-trip car commute for a single workday.
- Sanity-check with this case: A 30-mile round trip at 28 MPG and $3.89/gal costs about $4.17 in fuel, plus $3.00 wear at $0.10/mi → ~$7.17 per workday.
- The relationship is: Fuel cost = (miles ÷ MPG) × gas price; total workday cost = fuel + (miles × wear).
Localized examples

What you get
- Fields: Round-Trip Distance (mi), Fuel Economy (MPG), Gas Price ($/gal), Wear & Tear ($/mi)
- Fuel cost = (miles ÷ MPG) × gas price; total workday cost = fuel + (miles × wear).
- Example on the page: A 30-mile round trip at 28 MPG and $3.89/gal costs about $4.17 in fuel, plus $3.00 wear at $0.10/mi → ~$7.17 per workday.
How to Calculate Car Commute Cost Per Workday Step-by-Step
- 1Enter round-trip commute distance.
- 2Set your vehicle’s MPG and local gas price.
- 3Optionally include a per-mile wear estimate.
- 4Read fuel cost and total workday cost.
Governing formula
Fuel cost = (miles ÷ MPG) × gas price; total workday cost = fuel + (miles × wear).
A 30-mile round trip at 28 MPG and $3.89/gal costs about $4.17 in fuel, plus $3.00 wear at $0.10/mi → ~$7.17 per workday.
Example: set Round-Trip Distance (mi) = 30, Fuel Economy (MPG) = 28, Gas Price ($/gal) = 3.89, then read the result.

- Nothing here is uploaded for the calculation itself.
Frequently Asked Questions
Divide round-trip miles by MPG, multiply by gas price for fuel, then add miles × wear rate if you want a fuller cost.
