This is a rough estimate to help you understand the ballpark and the key factors — not an actual insurance quote. Real premiums vary by 30–100% between insurers for the same driver and vehicle. The policy comparison chart shows how the four cover types compare in cost.
Insurers use hundreds of proprietary rating variables — this calculator uses the main public factors (age, vehicle type, claims, NCB, parking, km). Your actual quote could be 30–50% higher or lower than this estimate. The estimate is most useful for understanding relative costs between cover types and the impact of individual factors like age or claims history.
The total annual insurance cost includes both your chosen comprehensive/TPFT cover AND CTP (compulsory third party). CTP is paid at registration time in NSW and QLD; it is built into registration fees in VIC and other states. The estimates shown for each state are for a standard passenger car — actual CTP varies by vehicle type, age, and (in NSW) the insurer you choose for the Green Slip.
Comprehensive is the only policy type that covers your own car in an accident. It covers: accidental damage (at-fault and not-at-fault), theft, fire, storm damage, flood, and damage to other vehicles. It does NOT cover: mechanical breakdown, tyres, personal items left in the car (check policy), or driving under the influence. Read the Product Disclosure Statement (PDS) carefully before purchasing.
The No-Claims Bonus is the largest discount available on car insurance — potentially 40–65% after 5 years. Understanding how it works helps you make better decisions about whether to claim or pay out of pocket.
For any claim, calculate: repair cost vs excess + NCB loss. If repair cost is $800, your excess is $600, and making the claim will drop your NCB by one level (costing ~$200–$400/yr for 2–3 years), the total cost of claiming could be $600–$1,800 more than just paying the $800 repair yourself. For any repair close to or below your excess, almost always pay out of pocket.
New drivers start with 0% NCB. After one claim-free year: ~10–15% discount. After 5 years: 40–65% depending on insurer. The premium difference between a new driver (0 NCB) and an experienced driver with 5+ year NCB on the same car can be 50–70% — this is why car insurance is so much cheaper at 30 than at 21, even before age loading factors out.
NCB protection allows one at-fault claim per policy period without losing your NCB. It typically costs $50–$150/yr. At 4+ years NCB, the protected discount is worth $400–$800/yr in premium savings. One unprotected claim drops you by 1–2 NCB levels, costing $300–$700 more per year for 2–3 years. The math strongly favours buying NCB protection once you have 4+ claim-free years. Key caveats: check if the protection applies only once every 3 years; check if the protection covers just the NCB or also prevents other claim loadings.
There are legitimate ways to meaningfully reduce your car insurance premium — some requiring minimal effort.
Loyalty rarely pays in Australian car insurance. Insurers often offer their best prices to new customers, not renewals. Set a calendar reminder 3 weeks before your renewal date to get at least 3 comparison quotes. Use comparethemarket.com.au or Canstar, then also quote directly with Budget Direct, AAMI, and your current insurer's online new-customer price (often different from your renewal price).
Use the Standard mode to see the excess field. Raising from $500 to $1,000 saves $150–$400/yr for most experienced drivers. At $1,500, savings can be $300–$700/yr. This strategy works best if: you have 3+ years NCB, you have emergency savings to cover the higher excess, and you have no reason to expect frequent claims. Do not raise your excess to an amount you could not afford to pay in an emergency.
For under-25s: (1) Consider being listed as a named driver on a parent's policy while you build NCB — cheaper than your own policy; (2) Look for telematics/black-box policies (some insurers monitor driving behaviour and discount safe drivers by 15–30%); (3) Do a defensive driving course — some insurers offer discounts; (4) Choose a car with a low insurance group — small, low-powered hatchbacks attract the lowest premiums; (5) Garage the car if possible — reduces theft risk significantly.
Getting the right insurance at the right price requires comparing both the premium and the policy terms — price is not the only factor.
Check the PDS for: new-for-old car replacement (some policies replace a new car if written off in first 1–3 years); hire car cover after accident; windscreen cover (some include as standard, others charge extra); towing; and agreed vs market value. A cheaper premium with a market value policy can result in a smaller payout than expected — particularly for older vehicles where market value may surprise you.
Your insurer should be able to pay your claim when needed. APRA (Australian Prudential Regulation Authority) regulates Australian insurers and publishes quarterly statistics. Large established insurers (IAG — NRMA, SGIC, RACQ; Suncorp — AAMI, Apia, GIO; Allianz; QBE; Budget Direct) all have strong capital positions. Avoid policies from unlicensed or overseas-only insurers.
Comparison sites (comparethemarket.com.au, iSelect, Finder, Canstar) cover most major insurers but not all. Budget Direct does not list on all comparison sites and is often among the cheapest for low-risk profiles. Get quotes from: (1) a comparison site; (2) Budget Direct directly; (3) your bank (many offer insurance through their app). Check that you are comparing the same excess and the same cover limits — adjusting one and comparing another is the most common comparison mistake.
The key factors insurers use to calculate your premium in Australia
Primary rating factors
| Factor | Impact on premium | Notes |
|---|---|---|
| Driver age (under 25) | +50–120% loading | Highest risk group — statistical accident rate is 2–3× average |
| Claims history | +40–130% per claim | At-fault claims raise premium significantly |
| Car value | Direct (sum insured) | Higher value = higher replacement/repair cost |
| Car make and model | ±20–50% | Sports cars, European luxury attract highest loading |
| No-Claims Bonus (NCB) | −10–65% | Largest available discount — builds over 5+ years |
| Excess amount | ±10–30% | Higher excess = lower premium (you bear more risk) |
| Location/postcode | ±10–30% | High-crime or high-accident postcodes attract loading |
| Annual kilometres | ±5–15% | More driving = more exposure |
| Parking type | ±5–15% | Garaged vehicles attract lower premiums |
How the premium is built
Insurers use proprietary actuarial models with hundreds of variables. The estimates in this calculator use representative market factors as indicative guidance only — actual premiums vary significantly by insurer. The only way to know your actual premium is to get a quote from at least 3 insurers, as pricing can vary by 30–100% for identical coverage.
Comparing the four types of car insurance and what each covers
| Cover type | Your car | Other cars/property | Fire/theft | Injury (CTP) |
|---|---|---|---|---|
| CTP only (compulsory) | ✗ | ✗ | ✗ | ✓ |
| Third party property (TPP) | ✗ | ✓ | ✗ | ✗ |
| Third party fire & theft (TPFT) | Fire/theft only | ✓ | ✓ | ✗ |
| Comprehensive | ✓ (accidental damage) | ✓ | ✓ | ✗ |
When each type makes sense
- CTP only: Never a full solution — CTP is compulsory but covers personal injury only. You must add at least TPP.
- Third party property: Good for older cars worth under $5,000 where you cannot justify comprehensive premiums. You are exposed if your car is stolen or damaged.
- TPFT: Middle ground — adds fire and theft protection. Good for cars worth $5,000–$15,000. Does NOT cover collision damage to your own car.
- Comprehensive: Best cover — recommended for any car worth $15,000+. Covers accidental damage, theft, fire, storms, floods, and damage to other vehicles. The only cover that pays for your own car if you are at fault in an accident.
Agreed value vs market value
Comprehensive policies offer either agreed value (fixed payout agreed at inception) or market value (insurer determines value at time of claim). Agreed value is preferable for most vehicles — particularly new cars and specialised vehicles — as market value can result in lower-than-expected payouts if car values have fallen. Agreed value premiums are typically slightly higher.
How the NCB works, how much it saves, and whether to protect it
No-Claims Bonus (NCB) structure
The NCB — also called No-Claims Discount (NCD) — rewards claim-free years with increasing discounts. In Australia, the structure varies by insurer but typically follows this progression:
| Claim-free years | Typical NCB discount |
|---|---|
| 0 (new driver) | 0% |
| 1 year | 10–15% |
| 2 years | 20–25% |
| 3 years | 25–35% |
| 4 years | 35–40% |
| 5+ years (maximum) | 40–65% |
Impact of a claim on NCB
One at-fault claim typically drops your NCB by 1–2 levels (e.g. from 5-year to 3-year). The premium impact is twofold: the NCB discount reduces AND the claim itself may trigger a loading. On a $1,500 premium, this can mean a $400–$600 increase in the following year. For minor repairs, it is often financially better to pay out of pocket than claim.
NCB protection
Most insurers offer NCB protection as an optional extra (typically $50–$150/yr). This allows one at-fault claim per policy period without losing your NCB. It is generally worth purchasing once you have 4+ years of NCB, as the NCB is worth more than the protection premium. Check the terms carefully — some policies only allow one protected claim every 3 years.
Transferring NCB between insurers
Your NCB follows you when you switch insurers. Ask your current insurer for a "claims history letter" or "NCB confirmation letter" when switching. Most Australian insurers accept written proof of NCB from other insurers. Do not lose your NCB by failing to declare it when getting a new policy quote.
Legal, practical ways to reduce your premium without sacrificing cover
Compare at least 3 quotes
The single most effective action: compare quotes from at least 3 different insurers. Premiums for identical coverage can vary by 30–100%. Use comparison sites (comparethemarket.com.au, iSelect, Canstar) AND go direct to insurers that do not list on comparison sites (Budget Direct, AAMI, Allianz). NRMA and RAA also offer member discounts not always visible on comparison sites.
Increase your excess
Raising your excess from $500 to $1,000 typically saves $200–$500/yr on comprehensive premiums. At $1,500, savings can be $400–$800/yr. The trade-off: you pay more out-of-pocket for any claim. This works well if you are a careful driver with a good claims history — you are effectively self-insuring minor claims.
Reduce annual kilometres
If you work from home or use public transport regularly, updating your annual km estimate can save $50–$200/yr. Be accurate — underestimating can void your claim. Some insurers offer pay-per-km policies (e.g. Mile Marker) that can significantly reduce premiums for low-mileage drivers.
Security and storage improvements
- Garage parking: saves ~5–15% vs street parking
- Approved alarm/immobiliser: saves ~3–8%
- Dash cam: some insurers offer discount for dash cam installation
- Avoid high-theft postcodes: not always possible but affects premium significantly
Named driver restrictions
Some policies allow you to restrict cover to named drivers only, reducing the premium. Conversely, adding a young driver as a named driver significantly increases cost. If a young person uses the car occasionally, check whether occasional driver declarations are better than full named driver inclusion.
❓ Frequently asked Frequently asked questions
How much is car insurance in Australia on average?
Australian comprehensive car insurance averages approximately $1,100–$1,900 per year for an experienced driver with no recent claims. Adding CTP (compulsory third party) of $350–$700 depending on state, total annual insurance costs are typically $1,500–$2,600 for standard vehicles and drivers. Young drivers (under 25) can pay 2–3× more due to age loading. Premium comparison sites consistently show 30–50% variation between insurers for identical coverage.
Is car insurance compulsory in Australia?
CTP (Compulsory Third Party) insurance is legally required to register a vehicle in all Australian states and territories. However, CTP only covers personal injury to others — it does not cover damage to your car, other vehicles, or property. You can legally drive with CTP only, but you have no cover for property damage or your own vehicle. Third party property insurance is the minimum sensible cover; comprehensive is recommended for any car worth more than approximately $8,000.
What does "excess" mean in car insurance?
The excess (also called "deductible") is the amount you pay out of pocket when making a claim before insurance covers the rest. A $600 excess means if you claim $3,000 of damage, you pay $600 and insurance pays $2,400. Higher excess = lower annual premium (you are taking on more risk). Most policies have a basic excess plus additional excesses for young drivers, inexperienced drivers, or unlisted drivers. Always check all applicable excesses when comparing policies.
What affects car insurance premiums most in Australia?
The biggest factors are: (1) driver age — under-25s pay 50–120% more; (2) claims history — each at-fault claim significantly raises premiums; (3) No-Claims Bonus — up to 65% discount after 5+ claim-free years; (4) vehicle type — sports and luxury vehicles attract large loadings; (5) postcode/location — high-crime and high-accident areas attract loadings; (6) annual kilometres driven; and (7) where the car is parked overnight. The insurer itself matters enormously — the same profile can attract quotes varying by 50–100%.
