How Much Car Can I Afford?

With running costs, the car would cost you $850 a month, 17% of your take-home pay.

What this means

A common guide is to keep car payments to about 10% of your take-home pay, and everything the car costs, with insurance, fuel and repairs, under about 20%. A car loses value from the day you buy it, so the less of your income it takes, the more is left for things that grow.

A shorter loan costs less interest and means you won’t owe more than the car is worth. Stretching to 7 years lowers the payment but adds interest, and you may still be paying when the car needs costly repairs. A good used car can cost far less for the same payment.

Where the money comes from

Paying for the car
  • Deposit$4,000
  • Loan$24,964
Assumptions in this estimate
  • A fixed-rate loan repaid monthly, with the deposit and trade-in paid towards the car. The starting rate is a typical one: Secured new car loans for good borrowers averaged 7.48% a year in July 2026 (Reserve Bank of Australia).
  • Advertised car prices already include VAT or GST.
  • Your actual rate depends on your credit, the lender and the car’s age. Dealers may offer lower rates on new cars, sometimes in place of a discount.

How the calculator works

  1. Your payment: a share of your take-home pay, 10% to start.
  2. What it borrows: the loan that payment repays over the term, at the rate you enter.
  3. The car price: the loan plus your deposit and trade-in, less any fees.
  4. All car costs: the payment plus insurance, fuel and repairs, as a share of your pay.

Example

On take-home pay of $5,000 a month, 10% is a payment of $500. Over 5 years at 7.48%, with a $4,000 deposit, that buys a car of up to $28,964, and you’d pay $5,036 of interest.

Ways to afford a better car

  • Save a bigger deposit: every $1,000 more adds $1,000 to the price without adding interest.
  • Improve your rate: compare a bank or credit union loan with the dealer’s offer before you go.
  • Look at nearly new: a car a few years old has already lost much of its value.

Frequently asked questions

How much should I spend on a car?

A common guide is to keep car payments to about 10% of your take-home pay, and everything the car costs, including insurance, fuel and repairs, under about 20%. On $5,000 a month, that’s a payment of up to $500.

Should I get a novated lease?

A novated lease lets you pay for a car from your pre-tax salary, which can save tax, especially on electric cars under the luxury car tax threshold, which are exempt from fringe benefits tax. Compare the total cost, including the residual payment at the end, with a car loan.

How long should a car loan be?

As short as you can manage. A 3 or 4-year loan costs much less interest than 6 or 7 years, and you’re less likely to owe more than the car is worth if you need to sell it.

Are on-road costs included?

Only in a drive-away price. Registration, compulsory third party insurance and stamp duty can add a few thousand dollars: enter them under fees.

Is it better to buy a new or used car?

A car loses a large part of its value in its first few years, so a good used car can cost far less for the same monthly payment. New cars often come with lower dealer finance rates and a warranty, which can narrow the gap.
