Fuel cost per mile/km (spend ÷ mileage)
Take your fuel receipts and the distance from the same period — see what each mile (or km) actually cost. Not TCO, just fuel from the pump.
Consumption tells you how much fuel you burn. This page turns receipts into fuel cost per kmmile. Budget one trip with trip fuel cost, the whole year with annual running cost, or full ownership with TCO.

How the results are calculated
Formula: fuel cost per distance unit = fuel spend ÷ distance. Per 100 units = result × 100. Units follow the header.
Optional: average fuel per month = spend ÷ months in the period.
This is a receipts method — brochure economy is not required. Not full TCO.
Using this motoring calculator
- Enter total pump spend and distance for the same period.
- Optionally enter months to see average fuel spend per month.
- Add months in the comparison table to see the cost-per-distance trend.
- Planning a route? Use trip fuel cost. Whole car? TCO.
Frequently asked questions
How does receipt spend ÷ mileage work?
Add up what you spent on fuel for a period and divide by the miles (or km) you drove in that same window. You get real fuel cost per distance — no catalog economy required.
How is this different from economy × pump price?
That path assumes a consumption figure and a pump price. This one uses what you actually paid on receipts — price swings and mixed driving included.
Why isn't this car TCO?
Here we only cover fuel from your receipts. TCO adds purchase, financing, insurance, service and depreciation.
What is the optional months field for?
It shows average monthly fuel spend: total ÷ months. Cost per distance still comes from spend and mileage alone.
How do monthly rows / the sparkline work?
You add month-by-month rows (spend + mileage). You'll see the trend of fuel cost per distance — the main result still uses the fields at the top.
Km or miles — where do I set that?
In the page header (metric vs US). Labels and the result flip automatically.
Do fuel-price swings break the result?
No — that's the point. Receipts already capture real prices from the period, so the result mirrors what you actually paid.
