Cost of Car Ownership Calculator

Cost of Car Ownership Calculator

What a car really costs over the years you keep it — the value it loses, fuel, insurance, servicing, parking and loan interest — in total, per month and per kilometre, with the return your down payment could have earned instead.

Total cost of ownership

Price + loan + running costs → cost per km
Ex-showroom price plus registration, road tax and first insurance.
Enter the full price to buy for cash; the loan is the rest.
Reducing balance, as car loans are quoted.
If the loan runs longer, what is still owed is paid off from the sale.
Your own estimate. Look up used prices of the same model at that age; it varies a lot by brand and fuel.
Your real figure from fill-ups; the brochure figure is usually better than real driving.
An example. Enter today’s pump price.
An average premium. The first year’s is often in the on-road price, and premiums fall as the car’s IDV falls.

$17,88,976Example

A $10,00,000 car, $2,00,000 down, the rest at 9% over 5 years, kept 7 years and sold for 45%; 12,000 km a year at 15 km/l and $100 a litre; insurance $25,000, servicing $15,000 and parking $12,000 a year, rising 4% a year

Worked example

A $10,00,000 car, $2,00,000 down, the rest at 9% over 5 years, kept 7 years and sold for 45%; 12,000 km a year at 15 km/l and $100 a litre; insurance $25,000, servicing $15,000 and parking $12,000 a year, rising 4% a year
Loss in value = 10,00,000 − 45% = $5,50,000
Running costs, year 1 = fuel 80,000 + 25,000 + 15,000 + 12,000 = $1,32,000; over 7 years at +4% = $10,42,575
Loan $8,00,000: EMI $16,607, interest over 5 years $1,96,401
Total = $17,88,976: $21,297 a month, $21.30 a km
The 2,00,000 down payment at 7% for 7 years would have earned $1,21,156

Resale values here are illustrative assumptions, not market data. Keeping a car longer spreads the early loss in value over more years.

Where the money goes

The price tag and the EMI are the parts of owning a car that everyone sees. The total cost of ownership adds the rest: the value the car loses, fuel, insurance, servicing and tyres, parking and tolls, and the interest on the loan. In the example a $10,00,000 car kept for seven years costs about $17,88,976 — $21,297 a month, or $21.30 for every kilometre driven. Here the running costs, $10,42,575, outweigh the loss in value, $5,50,000; for a costlier car or a shorter ownership the loss in value usually comes first. The money you get back when you sell is not a cost, which is why the page counts price minus resale rather than the price.

Resale value is the input to think hardest about. It depends on the brand, the fuel type, the kilometres and the condition, and on how the market treats older cars where you live; the page takes your estimate rather than inventing a depreciation rate. The chart spreads the loss at a steady yearly rate so that it reaches your figure in the last year; in reality a new car loses value fastest in its first year or two. For the value an insurer puts on the car at each age, see the car insurance IDV calculator.

Running costs follow the fuel cost calculator conventions: fuel used = kilometres ÷ km per litre, times the price. They are entered for year 1 and rise each year by the rate you choose. Loan interest counts only what you pay while you own the car; if the loan runs longer, the balance is cleared from the sale. Buying for cash removes the interest but not the cost of the money: cash tied up in a car cannot earn a return, so the page shows the opportunity cost of the down payment separately — $1,21,156 at 7% in the example, and $6,05,781 if the whole price were paid in cash. Whether to borrow or pay cash is the question the car loan vs cash calculator answers; the EMI itself comes from the car loan EMI calculator.

Road tax and registration are inside the on-road price. Fines, major accident repairs and a change of tyres or battery late in life are not modelled unless you add them to the yearly servicing figure. This is arithmetic on the figures you enter, not financial advice.

Frequently asked questions

How do I calculate the total cost of owning a car?

Add the loss in value (price minus resale), all running costs and the loan interest over the years you own it. The example comes to $17,88,976 over 7 years.

What is the cost per kilometre?

Total cost ÷ total kilometres driven: 17,88,976 ÷ 84,000 = $21.30 a km in the example — several times the fuel cost alone of $6.67 a km.

Is buying a car for cash cheaper than a loan?

It saves the interest, but the cash could otherwise have earned a return. The page shows that opportunity cost; the car loan vs cash calculator compares the two properly.

Why is resale value so important?

Because the loss in value is one of the two biggest costs, and the one you know least about in advance. In the example it is $5,50,000 of the $17,88,976 total; ten points more or less of resale moves the total by $1,00,000.
