The largest line in the budget

Works out what a car will be worth after a given number of years and turns the loss into figures you can compare: per month and per kilometre.

The calculator cuts the car's value by a set percentage each year: one rate for the first year and another for every year after. The rates are yours to enter — 18% and 10% are there as an example, not as market data.

Spread over years, months and kilometres, the loss becomes an ordinary running cost. A car bought for 2,000,000 at 18% and 10% is worth 1,076,004 after five years: 15,400 a month, or 12.32 for every kilometre over 75,000 km.

How to use

Enter the purchase price and the ownership period in years — fractions are fine.
Set the loss for the first year and for each later year, going by adverts for the same car at different ages.
Enter the mileage over the period to see the cost per kilometre.
Read the remaining value and the loss as a percentage, per year, per month and per kilometre.

Value year by year

Each row is a separate run of the calculator for a car bought at 2,000,000, losing 18% in the first year and 10% in each year after. The yearly loss in money falls because the percentage is taken from a value that is already lower.

Every row comes from the calculator on this page.
Period	Mileage	Value	Lost	Per month	Per km
1 year	15,000 km	1,640,000	18%	30,000	24
3 years	45,000 km	1,328,400	33.6%	18,656	14.92
5 years	75,000 km	1,076,004	46.2%	15,400	12.32

What to keep in mind

The percentages are your assumptions; the calculator knows nothing about the market for a particular model.
A part year counts as that share of the year's rate: 2.5 years is two full years and half of the third.

FAQs

What percentages should I use?

Your own: find adverts for the same car at one, three and five years old and compare them with the new price. The 18% and 10% already filled in are only an example.

Why does the monthly loss fall over time?

The percentage is taken from the current value, which keeps shrinking. A 2,000,000 car loses 360,000 in its first year, an average of 184,799 a year over five and 151,949 over eight.

How do I work out depreciation per kilometre?

Divide the loss by the mileage. 923,996 over 75,000 km is 12.32 a kilometre — easy to add to the fuel cost per kilometre.

How is two and a half years counted?

Two full years at their rates and half the third year's rate: a 2,000,000 car at 18% and 10% is worth 1,402,200 after 2.5 years.

What else goes into the cost of ownership?

Fuel, insurance, tax, tyres, servicing and repairs. The site has separate calculators for fuel and, under Russian rules, for motor insurance and vehicle tax.

How much is lost over five years at 18% and 10%?

46.2%: 0.82 × 0.9⁴ = 0.538 of the price remains. At 12% and 7% the loss is 34.2%.

Worked example

A new car at two million

Input: 2,000,000, 5 years, 18% and 10%, 75,000 km

Output: Worth 1,076,004, a loss of 923,996 — 46.2%

Note: That is 15,400 a month and 12.32 a kilometre. At 12% for the first year and 7% after, the same five years would leave 1,316,572.
