How to save for a car: amount, timeline and running costs

You buy a car once and pay for it every month. It is worth saving with both numbers in mind.

2026-10-02

In short

To save for a car, set the price and add registration, taxes and insurance, then divide the total by the months until you buy — that is your monthly saving. For example, 12 000 over two years is 500 a month. Work out the running costs in advance: fuel, insurance, maintenance, registration and parking. If the monthly running cost does not fit your budget, a cheaper car beats saving for longer.

A car is one of the most common big goals and one of the trickiest. The price in the listing is only the start: after you buy it, the car costs money every month, and that is worth knowing before you start saving.

Step 1. The full amount

Price

Of the car you chose

New or used

Taxes and registration

Fees and paperwork

A few percent more

Insurance

The first year

Often paid upfront

Example: a used car for 11 000, with taxes, registration and the first insurance payment around 1 000. Goal: 12 000.

Step 2. How much to save each month

1 year

12 000

1 000 a month

2 years

12 000

500 a month

3 years

12 000

334 a month

Choose the timeline where the monthly amount does not push you onto a credit card at the end of the month. The arithmetic for big purchases: how much to save each month for a big purchase.

Step 3. Work out the running costs before you buy

Fuel

Depends on mileage

The most visible cost

Maintenance

Oil, tyres, repairs

Set it aside monthly

Insurance and registration

Yearly

Divide by twelve

Parking and washing

The small stuff

That adds up

Add these up for a year and divide by twelve: that is what the car costs per month. If it is more than you spend on transport now, the difference has to come from the budget before you buy. A good test: while you save, also set aside the future monthly running cost. That shows whether your budget can carry it.

Save or borrow

A loan lets you buy sooner, but while you pay, the car loses value and the interest does not. Saving at least half the price means less interest and less dependence on your income over the next few years. If you do borrow, check how it changes your debt-to-income ratio.

On a low income

Then it matters to start with an inexpensive used car and an emergency fund: the first big repair should not land on a credit card. Emergency fund, then how to save on a low income.

What it looks like in the app

In Caudal create a goal called "Car" with an amount and a date: the app works out how much to set aside each month and recalculates it after every contribution. You can add a photo of the model — a goal you can see is dropped less often. If the car is one of several big purchases you are planning, add them all to the Wishlist with their months: the app shows which months need more than you usually have left and suggests what to move. Once you own the car, create a category for it with subcategories — fuel, maintenance, insurance — and a monthly limit, so you can see what it really costs.

Common questions

How much should I save each month for a car?
Divide the full amount — price, taxes, registration and first insurance — by the months until you buy. For example, 12 000 over two years is 500 a month; over three years, 334.
Is it better to save for a car or take out a loan?
Saving usually costs less: there is no interest and the car loses value from day one. If you need a loan, save at least part of the price — it lowers both the interest and the monthly payment.
What does a car cost apart from the price?
Taxes, registration and insurance when you buy, then every month fuel, maintenance, repairs, parking and washing. Add up a year and divide by twelve to see the real monthly cost.
