How much could my children save by not buying a car?

Buying and running a car can seriously delay young people’s ability to save for a home. This article uses a simple example to show how avoiding car ownership, using public transport and saving the difference can bring a first-home down payment much closer.

A 44-year-old woman asks:
Hi Björn. I’m the mother of young university students. Could you calculate for them how much they might save each year by not buying and running a car? Maybe also show how many years buying a car could delay them saving enough for a down payment on a home?
It can be useful to look at the figures from FÍB, the Icelandic Automobile Owners Association. They publish estimates of the cost of owning and running a car, with the most recent figures available from last year.
Their calculations do not include recent kilometre charges, changes in fuel prices or the temporary reduction in VAT. Even so, I think their summary gives us a fairly good picture of the overall cost.
Cars are expensive
FÍB gives six different examples.
Let’s use the cheapest one here. That example is based on a petrol car costing ISK 3.9 million and being driven 15,000 km a year. The total annual cost is estimated at around ISK 1.6 million.
That clearly affects the ability to save for a home. Money does not usually fall from the trees while we are studying at university.
The saving can be substantial
Instead of owning a car, they could use other ways of getting around.
Since I don’t know how far they need to travel to school, work or for leisure, I have to make some assumptions. Let’s assume they can take the bus, use scooters now and then, and occasionally take a taxi when needed.
An annual student bus pass costs ISK 58,000.
Using a Hopp scooter for 10 minutes, twice a week, also costs about ISK 58,000 a year.
One taxi ride a month might cost around ISK 84,000 a year. Together, that comes to ISK 200,000.
In this example, owning a car would therefore be eight times more expensive. By avoiding the car, they would save around ISK 1.4 million a year.
How much difference would that make?
Now let’s assume that the saving is put aside each month and earns a 6% annual return.
Year | Savings |
|---|---|
1 | ISK 1.4 million |
2 | ISK 3.0 million |
3 | ISK 4.6 million |
4 | ISK 6.4 million |
5 | ISK 8.1 million |
6 | ISK 10.0 million |
As you can see, these are large amounts of money.
The dream of saving enough for a down payment on a home is absolutely within reach. On top of these amounts, they could add accumulated supplementary pension savings (viðbótarlífeyrissparnaður), which may be used tax-free under current first-home rules, as well as any other money they would have saved if they had decided to buy a car.
If the goal is to save a 15% down payment for a home costing ISK 65 million, the transport saving in our example should, by itself, be enough to buy the home in under six years.
If the goal is a 10% down payment on a home costing ISK 60 million, it would take less than four years.
Since I don’t know their full financial situation, I cannot combine these scenarios with their other saving capacity or say exactly how much buying a car would delay the purchase of a home. But the difference could easily be several years.
Avoid the car loan
Cars can, of course, be convenient. In some cases, they may even be necessary. But they are usually a poor investment and expensive to run.
They become even worse if the purchase is financed with a loan. So if they do decide to buy a car, I would strongly encourage you to do everything you can to help them avoid taking out a car loan.
Buying a car is not just about the price on the windscreen. It is also about the years of saving, flexibility and future opportunities that may disappear with it.
