Is it cheaper to buy a new or used car in Australia?

In many cases a used car has a lower purchase price, but that does not always mean it is cheaper overall.

A used vehicle may have:

• higher interest rates
• more maintenance or repair costs
• less warranty protection
• lower resale value after a few years

A new car may cost more upfront but can sometimes offer:

• lower finance rates
• fewer repairs
• manufacturer warranty
• better resale value

The BestCarPrice.au calculator helps you compare the true 5-year cost of ownership so you can see which option may be better value.

How accurate is the New vs Used Car Calculator?

The calculator provides an estimate based on the inputs you enter, including purchase price, interest rates, repair expectations and resale value.

Actual ownership costs may vary depending on factors such as:

• how much you drive
• servicing costs
• fuel prices
• resale market conditions
• vehicle reliability

The tool is designed to give a realistic comparison scenario, not a guaranteed outcome.

Why can a new car sometimes cost less than a used car over time?

Many buyers assume a used car will always be cheaper, but that is not always the case.

A new car may end up costing less over time because of:

• lower interest rates on new car finance
• manufacturer warranty coverage
• fewer repair bills
• stronger resale value
• fixed servicing plans

When these factors are included, the total cost difference between new and used can sometimes be much smaller than expected.

What costs should I consider when buying a car in Australia?

The real cost of owning a car usually includes more than just the purchase price.

Typical costs include:

• purchase price
• loan interest
• insurance
• registration
• fuel or electricity
• servicing
• tyre replacement
• repairs
• depreciation
• resale value

The BestCarPrice.au calculator focuses on the biggest financial factors to help you make a clearer comparison.

Is it better to buy a new car or a used car for reliability?

Generally, a new car is more predictable because it comes with a full manufacturer warranty and no previous wear.

Used cars can still be very reliable, especially if they:

• have full service history
• are relatively low kilometres
• come from a reputable seller
• have been inspected by a mechanic

If reliability and peace of mind are a priority, a new car may offer more confidence.

How much does a car depreciate in Australia?

Depreciation varies depending on the vehicle, but a typical new car may lose 15–25% of its value in the first year and around 40–50% over five years.

Some vehicles hold their value better than others, particularly:

• Toyota
• Mazda
• Subaru
• Isuzu
• popular SUVs and utes

Resale value is an important factor in the calculator because it affects the real long-term cost of ownership.

Should I buy a new car if I plan to keep it for a long time?

Buying a new car can make more financial sense if you plan to keep it for many years.

Benefits may include:

• full warranty coverage during early ownership
• fewer repair surprises
• newer safety features
• known service history
• longer lifespan

Many Australians keep cars 7–10 years, which can reduce the impact of early depreciation.

Are finance rates different for new and used cars?

Yes. Finance rates are often lower for new cars compared with used vehicles.

This is because lenders typically see new vehicles as lower risk.

For example, a new car loan may offer:

• promotional interest rates
• dealer finance incentives
• novated lease options
• manufacturer-backed finance

Higher interest rates on used cars can increase the total cost of ownership.

What is the best age for a used car to buy?

Many buyers consider 2–5 years old to be the sweet spot.

At this age a vehicle has usually:

• already taken the largest depreciation drop
• modern safety features
• relatively low kilometres
• some remaining reliability

However, condition and maintenance history are often more important than age alone.

Should I buy a demo car instead of new or used?

A demonstrator (demo) vehicle can sometimes offer the best of both worlds.

Demo cars are typically:

• near-new vehicles
• sold by dealerships
• slightly discounted
• still covered by manufacturer warranty

They may have low kilometres but can cost less than a brand-new model.

Does warranty make a big difference when comparing cars?

Warranty coverage can significantly reduce unexpected ownership costs.

Many new cars in Australia now offer 5–10 year warranties, which can protect against expensive mechanical repairs.

Used cars may not have warranty coverage unless they are:

• certified used vehicles
• still within the manufacturer warranty period
• covered by a dealership warranty program

Warranty value is included in the calculator because it reduces risk.

What types of cars hold their value best in Australia?

Vehicles that tend to retain strong resale value include:

• popular SUVs
• dual-cab utes
• hybrid vehicles
• reliable Japanese brands

Examples often include:

• Toyota RAV4
• Toyota HiLux
• Ford Ranger
• Mazda CX-5
• Isuzu D-Max

Strong resale value can significantly reduce the long-term cost of ownership.
