Two job offers with the same salary are not equal if one adds an hour each way to your day. Commuting drains both money and time, and both deserve a dollar figure when you compare opportunities. Quantifying the full cost helps you weigh pay against location and decide what a shorter commute is worth.
The direct money cost
Driving costs far more than fuel once you include maintenance, tires, depreciation, and a share of insurance. A reasonable proxy for the all-in cost of driving is the IRS standard mileage rate, which was 70 cents per mile in 2025. Multiply your round-trip distance by that rate and by your working days to estimate the annual cost. Note that commuting to a regular workplace is not tax-deductible for employees, so this is an after-tax expense.
Putting a value on your time
Time spent commuting is time you cannot spend earning, resting, or with family, so it has real value. A simple method is to value commuting hours at your effective hourly wage, or at a personal rate that reflects what your time is worth to you. An hour each way, five days a week, is roughly 500 hours a year, the equivalent of more than 12 full work weeks. Even valued modestly, that time cost often dwarfs the fuel bill.
Comparing offers and commute modes
When two offers differ in commute, convert the difference into an annual dollar figure and subtract it from the salary. A job paying $5,000 more but adding a costly, time-heavy commute may net out behind a closer, lower-paying role. Public transit, carpooling, or remote days can shrink both the money and time costs substantially. Running the numbers turns a vague preference for a shorter commute into a concrete comparison.
Ben is offered a job 25 miles away, a 50-mile round trip. At 70 cents per mile over about 250 workdays, driving costs roughly $8,750 a year. Add 500 hours of commuting valued at just $20 per hour, another $10,000, and the true cost of that location approaches $18,750 before he weighs it against the salary.
Key takeaways
- The IRS mileage rate, 70 cents per mile in 2025, approximates the full cost of driving.
- Value your commuting time, not just fuel, since the time cost is usually larger.
- An hour each way is about 500 hours a year, roughly 12 work weeks.
- Subtract the annual commute cost from salary to compare offers fairly.
Common mistakes
- Counting only gas and ignoring maintenance, depreciation, and insurance.
- Treating commuting time as free when it has a clear opportunity cost.
- Comparing salaries between offers without adjusting for very different commutes.
FAQ
Can I deduct my commute on my taxes?
No. Commuting between home and your regular workplace is a personal expense and is not tax-deductible for employees.
How should I value my commuting time?
A practical approach is your effective hourly wage, though you can use a higher personal rate if your free time is especially valuable to you.
