Add up a year of keeping the car on the road — fuel, insurance, service, tires and the rest — then see it monthly and per mile.
Need fuel economy first? Use the fuel consumption calculator. Planning one trip? Use trip cost. Checking real fuel spend? Use fuel cost per mile. This page totals your whole year.

Fuel (US): gallons = miles ÷ mpg; cost = gallons × $/gal. Metric: litres = (km ÷ 100) × L/100 km; cost = litres × price/L.
Annual total: fuel + service + insurance + tires + (parking monthly × 12) + tax.
Monthly = annual ÷ 12. Per distance = annual ÷ mileage. Share % = category ÷ total × 100.
Total annual cost $3,881.43
Monthly $323.45 · Per mile $0.3235
A typical commute profile — insurance (30.9%) and fuel (35.3%) together make up more than two-thirds of the yearly cost.
Total annual cost $2,640.00
Monthly $220.00 · Per mile $0.5280
At low mileage, fixed costs dominate — insurance (34.1%) and parking (22.7%) together are more than half the total, while fuel is only 18.9%. Cost per mile is higher than in Example 1 because fixed costs are spread over fewer miles.
Total annual cost $6,163.33
Monthly $513.61 · Per mile $0.2465
At high mileage, fuel becomes the dominant category (54.1% of the total). A good moment to compare economy in the fuel consumption calculator — even a small mpg improvement at this mileage means meaningful yearly savings.
Six categories: fuel, service/inspection, insurance, tires, parking/wash, and tax/registration. No purchase price, loan/lease payments, or depreciation — those belong in TCO.
Formula: (annual distance ÷ 100) × L/100 km × fuel price. Switch units in the header and the JS adapts the numbers to km / L/100 km or mi / mpg.
Easiest: subtract odometer readings from the start and end of the year. Or estimate daily commute × workdays plus weekend trips. For one route, use trip fuel cost.
This page covers repeatable costs for one year. TCO adds purchase, financing and depreciation over several years.
Financing isn't here — that's ownership, not running cost. Put lease/loan together with the rest in TCO.
Yes — run it twice with different inputs (e.g. gasoline vs hybrid) and compare total annual cost plus cost per mile/km.
Fixed costs (service, insurance, tax) stay put — fuel scales with distance. FAQ examples update to the units in the header.
It depends heavily on the car, mileage, region and local prices — there's no single magic number. Enter your own figures.
No — you enter your own current amounts. That way the result tracks your spending, not a network average.
Use the units selector in the header (US ↔ Metric). Fields, results, examples and FAQ figures update automatically.
