Vehicle Operating Cost Calculator
Work out your true vehicle cost per km or mile — depreciation, fuel, and annual fixed costs combined into a single chargeable rate.
Work Out Your Vehicle Cost per km or mile
Calculate exactly what it costs you to run your work vehicle — per kilometer or per mile. Combines depreciation, fuel, insurance, registration, servicing, tires, and any other annual costs into a single true-cost figure, then applies your markup to give the charge rate you should bill clients for travel. Use the result on its own, or feed it into job estimates and travel charges.
Distance Unit
Pick once — all distance and fuel inputs below adjust. Existing values are math-converted so your vehicle profile stays consistent.
Vehicle Depreciation
Spread the purchase price (less expected resale) across the miles you expect from the vehicle.
Fuel
$/gal ÷ MPG → $/mile.
Annual Fixed Vehicle Costs
Yearly costs spread across the miles you drive in a year. Together these become your annual fixed cost per mile.
Charge Rate Markup
Buffer on top of true cost — covers wear and tear, finance interest, and the time-cost of loading the vehicle. Typically 15–25%.
Enter your vehicle's purchase price to see your cost per mile. The other fields are pre-filled with typical US work-vehicle values — adjust any of them to match yours.
This is your vehicle operating cost per mile — the rate to charge clients for travel, or to feed into a full job estimate. It covers the vehicle only — not the driver's labor, tolls, or trailer hire.
How the Vehicle Operating Cost Calculator Works
- Pick your distance unit — kilometers or miles. The fuel input switches to L/100km or MPG to match.
- Enter the vehicle's purchase price, expected resale value, and total lifetime distance — these give your depreciation per km/mile.
- Enter your fuel economy and pump price — the calculator converts to $/km or $/mile automatically.
- Add your annual fixed costs — insurance, registration, servicing & repairs, tires, and any other yearly outlays — plus the distance you drive per year.
- Set a charge-rate markup % to get from true cost to the rate you charge clients.
- Review the Recommended Charge Rate per km/mile and copy the summary for your records or quotes.

Frequently Asked Questions
What does this calculator include — and what does it leave out?
It covers everything tied directly to running the vehicle: depreciation, fuel, insurance, registration, servicing & repairs, tires, and any other yearly costs you flag. It does NOT include the driver's labor, tolls, parking, or trailer/equipment hire — add those separately when pricing a job. The output is the per-km/mile rate to charge for the vehicle itself.
How is the True Vehicle Cost per km/mile worked out?
Three components add together: (1) Depreciation = (purchase price − resale value) ÷ lifetime distance; (2) Fuel = fuel use × fuel price — (L/100km ÷ 100) × $/L in metric, or $/gal ÷ MPG in imperial; (3) Annual fixed cost = (insurance + registration + servicing + tires + other) ÷ annual distance driven. The Recommended Charge Rate is then True Cost × (1 + markup ÷ 100).
How should I set the Charge Rate Markup %?
This is your buffer on top of true cost — it covers the things hard to model precisely (extra tire wear on unsealed roads, the time-cost of loading the vehicle, unexpected repairs, finance interest). 15–25% is typical for contractors. If you bill clients separately for a profit margin elsewhere on the quote, keep this markup conservative and let the overall margin do the heavy lifting.
How do I find my annual distance driven?
Check your odometer over a 12-month period, or look at service records if your mechanic notes the reading. For a brand-new vehicle, estimate based on typical job patterns — but revisit and update this number once you have real data, because it has a big effect on the per-km/mile fixed-cost component.
Why is my fixed cost per km so different from someone else's?
Annual fixed cost ÷ annual distance does the heavy lifting. A contractor driving 50,000 km/year on the same vehicle has roughly half the per-km fixed cost of someone driving 25,000 km/year. Insurance and registration are flat, so they hurt low-mileage drivers more. If your number looks high, check whether you're including costs that don't belong (e.g. fuel inside "servicing"), or whether your annual distance is too low.
Should I include tires separately or roll them into servicing?
Either works — the calculator gives tires their own line because for contractors who run heavy loads or unsealed-road sites, tires are a big cost worth tracking. If you prefer one combined "service & wear" line, leave tires at 0 and put the total in servicing.
How accurate is this for a brand-new vehicle?
Depreciation is the hardest figure to nail in year one because the steepest drop happens early. For a more conservative estimate on a new vehicle, set the expected resale value lower (or use a 5-year industry depreciation chart for that make/model). The other components — fuel, fixed annual costs — are accurate from day one.
Important Notes
- The Recommended Charge Rate is what you bill clients for the vehicle per km/mile — your true cost plus the markup buffer.
- Annual fixed cost ÷ annual distance is your real "per-km overhead" — drive less, and this number goes up.
- Update the annual fixed cost figures once a year as insurance and registration renewals come through.
- For multi-vehicle fleets, run the calculator separately for each vehicle and use a weighted average if you bill a single rate.
- Feed this rate into a full job estimate, or use it alongside the Concrete Grinding Cost Calculator to build a complete per-unit cost picture.
