Small daily drives add up. A modest commute can quietly cost thousands of dollars a year in gas — this calculator turns your one-way distance and fuel economy into the weekly, monthly, and yearly total so the real number is impossible to ignore.
What drives the cost
The yearly figure is your round-trip distance, times days commuting, times 52 weeks, divided by your MPG, times the pump price. Because every factor multiplies, improving any one of them — a shorter route, a more efficient car, one work-from-home day — compounds into real savings.
This counts fuel only. The true cost of driving also includes maintenance, insurance, and depreciation, which add several times the fuel cost per mile.
A worked example
A 15-mile one-way commute — 30 miles round trip — five days a week in a 28-MPG car at $3.50 a gallon costs about $3.75 a day. That's roughly $18.75 a week, $81 a month, and $975 a year, for fuel alone. Cutting to three days a week (with two days remote) drops the yearly figure to about $585.
The costs beyond gas
Fuel is only part of what a commute costs. Add maintenance, tires, insurance, and depreciation, and the all-in cost per mile runs several times the fuel cost — often around 60–70 cents a mile for a typical car. On that basis, the commute above could really cost $4,000–$5,000 a year.
That fuller number is the one worth weighing against alternatives: a shorter commute, public transit, carpooling, or a remote day or two. Even small reductions compound, because you're multiplying a daily cost by roughly 250 working days a year.
