Short answer: If you have the cash and it isn't needed for emergencies or earning more elsewhere, buying outright is usually cheaper because you pay no interest. Finance can make more sense if paying cash would wipe out your safety net, if the money is reducing a higher-rate debt, or if the car is for business and the tax treatment works in your favour.
The cost of borrowing
Example only: $30,000 over 5 years at 9% p.a. works out to about $623 a month and roughly $7,365 in total interest, before any fees. That's the price of keeping your $30,000 in the bank. The question is whether keeping that cash is worth more than $7,365 to you.
When paying cash usually wins
- You'd still have a healthy emergency fund afterwards, often several months of expenses.
- Your savings earn much less after tax than the loan would cost.
- You have no higher-rate debts, such as credit cards, that the cash should go to first.
- You want to avoid a monthly commitment, for example before retirement or a change in income.
When finance can make sense
- Protecting your buffer. Spending everything on a car and then facing a big bill can push you onto expensive credit.
- Money in a home loan offset. Cash in an offset reduces home loan interest. Compare that saving with the car loan rate before you withdraw it.
- Business use. With a chattel mortgage, a business can own the car, may claim interest and depreciation for the business-use share, and GST-registered businesses can usually claim the GST credit upfront. The ATO car limit caps how much of a car's cost counts for depreciation. Check the details with your accountant.
- Building credit history. A loan paid on time adds positive repayment history to your file. That alone isn't a reason to borrow, though.
Side-by-side
| Buy outright | Finance | |
|---|---|---|
| Interest cost | None | Depends on rate, term and fees |
| Savings buffer | Reduced | Kept |
| Monthly budget | No repayment | Fixed repayment for the term |
| Insurance | Your choice | Lender usually requires comprehensive cover |
| Selling later | Straightforward | Loan must be paid out first |
A middle path
Many buyers put down a decent deposit and finance the rest. That cuts the interest bill and keeps some cash in reserve. Just check the early payout terms if you might clear the loan sooner. Moneysmart has a guide to car loans and calculators that help with the comparison.
