How this is worked out
- Start from the EPA combined figure for the model year — a laboratory test cycle run to a fixed procedure, not a road result. Where a year sold several engines or drivetrains, the trims are averaged and the trim count is printed beside the row so you can see how much averaging is behind it.
- Fix a pump price. This site keeps one reference price, $3.20 a US gallon, fixed JUL 2026 and printed next to every dollar figure it produces. It is an assumption with a date on it, not a quote — put your own price in.
- Fix an annual distance. Every annual figure on this site uses 15,000 miles a year, roughly the US average. A cost per year with no stated distance is not a number, it is a mood.
- Divide distance by economy for gallons, multiply by price for the year's fuel, divide price by economy for one mile. The per-kilometre line is that last figure divided by 1.609344 — the same money, in the unit most of the world drives in.
- Stop there. No depreciation, no tyres, no insurance, no servicing. This is the fuel line of the ledger and it is labelled as one; depreciation usually dwarfs everything on it.
gallons/yr = miles/yr ÷ MPG fuel $/yr = gallons/yr × $/gal cost $/mi = $/gal ÷ MPG cost $/km = cost $/mi ÷ 1.609344

Questions asked across the counter
Which is more fuel efficient, the Volvo XC90 AWD or the Lincoln MKX AWD?
The Volvo XC90 AWD is more efficient — 22.5 MPG against 19 for the Lincoln MKX AWD. Over 15,000 miles a year at $3.20 a gallon that is a saving of about $393 a year, or $1965 over five years.
Which is cheaper to run, the Volvo XC90 AWD or the Lincoln MKX AWD?
On fuel alone, the Volvo XC90 AWD: $2133 a year against $2526 for the Lincoln MKX AWD, both at $3.20 a gallon over 15,000 miles — an assumption fixed JUL 2026. Fuel is the only line being compared: depreciation, insurance, tyres and servicing are not in it, and they routinely matter more than this gap.
Is the difference big enough to change the decision?
Across five years of that same driving the gap comes to about $1965. That is real money, and it is also roughly what one year of depreciation does to a new car — so treat it as one line in the ledger rather than the whole argument.
