Type annual mileage, fuel economy, pump price, plus service, insurance, tires, parking, and tax. At 12,000 miles, 28 mpg and 3.20 per gallon plus the fixed lines from example 1 you get 3,881.43 for the year. That is a running-cost year, not TCO.
Need economy first? Use the fuel consumption calculator. One trip: trip fuel cost. Receipts: cost per mile. This page totals the year.
Annual mileage, Fuel economy, Fuel price and Service / annual inspection. The result shows up here.
Fuel in US units: gallons = miles ÷ mpg, then times price. 12,000 / 28 × 3.20 ≈ 1,371.43. Metric: liters = (km ÷ 100) × L/100 km, times price per liter. You then add service, insurance, tires, monthly parking × 12, and annual tax.
Example 1: 12,000 miles, 28 mpg, 3.20, service 600, insurance 1,200, tires 200, parking 30 a month, tax 150 totals 3,881.43, or 323.45 a month and 0.3235 per mile. Fuel is about 35.3%, insurance 30.9%. Example 2 at 5,000 miles falls to 2,640 but 0.5280 per mile, because the fixed lines do not shrink.
At 25,000 miles, 24 mpg and the same 3.20 plus higher fixed lines you get 6,163.33, with fuel at about 54.1% of the total and 0.2465 per mile. Fields are annual mileage, fuel economy, price, service, insurance, tires, parking / wash, and tax / registration. Parking is monthly; the rest are yearly.
The metric header relabels mileage to kilometers and economy to L/100 km. A typed 12,000 is not rewritten as kilometers. A comma in 3.20 and 6.39 parses. Third-party and comprehensive insurance go in as one yearly amount; this form does not price them.
One trip lives on trip fuel cost. Receipts ÷ mileage live on cost per km. TCO adds purchase, a payment, and value loss. There is no car price here. Blank mileage does not fill 12,000 from the example. Zero mileage leaves the fixed lines with no fuel.
Type the example 1 numbers, click Calculate, and match 3,881.43. Then drop to 5,000 miles: 2,640. That is an estimate from categories you type, not a live pump feed.
Fuel from mileage plus service, insurance, tires, parking, and tax. 12000 miles, 28 mpg, and 3.20 a gallon plus example 1 fixed lines total 3881.43 for the year.
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.
3,881.43 a year, 323.45 a month, 0.3235 per mile. Fuel ≈ 1,371.43 (35.3%), insurance 1,200 (30.9%).
2,640 a year and 0.5280 per mile. Fixed lines (insurance 34.1%, parking 22.7%) outrun fuel at 18.9%.
6,163.33 a year and 0.2465 per mile. Fuel is about 54.1% of the total.
There is no purchase, payment, or value loss here. TCO adds capital. Here six running-cost lines.
No. The field is monthly and the calculator multiplies by 12. Tax and insurance are yearly amounts you type.
Use the Metric header. Labels go to kilometers and L/100 km. A typed 12,000 is not converted by itself.
The calculator does not build a year and does not fill 12,000 from the example. Zero mileage leaves service, insurance, tires, parking, and tax.
No. You type 3.20 or 6.39. The station does not connect to this page.
On the fuel consumption page from distance and fuel added. Here you already type a known economy.
Yes: a yearly average for sets, not one tire. Zero is fine in a year you do not buy any.
Use, cost or emissions come from your numbers. Below are FuelEconomy.gov, EPA and SI terms.
