Calculate the daily, weekly, and annual gas cost of your commute.
This tool projects your commute's gas cost -- daily (round trip), weekly, and annually -- from your one-way distance, vehicle MPG, gas price, and how many days/weeks per year you actually commute. This is a fuel-cost-only estimate; it complements the separate Commute Time Calculator, which measures time rather than cost.
Enter your one-way commute distance, vehicle MPG, price per gallon, commute days per week, and working weeks per year. Your daily, weekly, and annual commute gas cost appear instantly.
The calculator doubles your one-way distance to get a round trip, divides that by your MPG to get gallons burned, and multiplies by the price per gallon. That gives the daily cost. The weekly figure is the daily cost times your commute days per week, and the annual figure is the weekly cost times your working weeks per year. Nothing else is added: no tolls, no parking, no maintenance, no depreciation, and no extra fuel for errands or detours.
Daily = (one-way miles x 2 / MPG) x price per gallon. Weekly = daily x days per week. Annual = weekly x weeks per year.
Suppose you drive 20 miles each way, your car averages 25 MPG, and gas costs $4.00 per gallon. The round trip is 40 miles, which uses 1.6 gallons, so the daily cost is $6.40. If you drive in four days a week and work 48 weeks a year, the weekly cost is $25.60 and the annual cost is $1,228.80. Now change one input: if you move to a car that gets 35 MPG, the daily cost falls to about $4.57, and the annual cost falls to roughly $877. Running the calculator both ways is a quick, concrete way to see what a more efficient vehicle or a shorter drive is worth to you in fuel alone.
The most frequent error is treating this figure as the total cost of driving to work. Fuel is often only part of the picture. Tolls, parking, tires, oil changes, insurance mileage tiers and depreciation all rise with miles driven, and none of them are in this result. If you want a fuller comparison against public transit, carpooling or a job closer to home, add those items yourself as separate lines. A second limit is that the tool assumes the same MPG and price for every trip in the year, while real prices and efficiency move with seasons, weather, tire pressure and traffic. Treat the annual figure as a planning estimate, not a prediction accurate to the dollar. Finally, an MPG of zero or a blank field will produce a zero result, so check that all inputs contain sensible values if the output looks wrong.
People commonly use a commute fuel estimate when weighing a job offer in a different location, deciding whether a longer drive for a higher salary is really worth it, comparing an electric or hybrid vehicle against a gasoline one, or setting a budget for a new remote or hybrid schedule. It is also handy for asking an employer about a commuting stipend, since you can show a clear calculation. If you claim work-related driving on a tax return, the rules are specific and differ from a simple fuel estimate, so consult IRS.gov or a tax professional rather than using this number directly.
No -- this is fuel cost only. Add tolls, parking fees, and other commuting costs separately for a complete picture of your total commute expense.
Enter the one-way distance. The calculator multiplies it by two internally to get the daily round trip, so entering a round-trip figure would double count the distance.
The result scales directly with commute days per week. Going from five days to three cuts the annual fuel cost to 60 percent of its original value, assuming everything else stays the same.
Your real spending includes non-commute driving, and your actual MPG and gas prices change through the year. This tool covers only the commuting portion under the fixed inputs you enter.
Yes, but use a blended MPG that reflects both. If the two legs differ a lot, you can run the calculator separately for each leg and add the results.
