I don't have any emergency savings. Is choosing a bigger car insurance excess to save money a bad idea?
No — but if you have no emergency savings, choosing a bigger car insurance excess is probably not the best move right now. I’d generally prioritise being able to afford an unexpected bill over saving a little on your regular premiums.
In New Zealand, your car insurance excess is the amount you usually have to contribute towards a claim. Choosing a higher excess can lower your premium, but it also means you need more money available if something goes wrong.
The key question isn't just whether a higher excess saves you money. It's whether you could actually afford to pay it at short notice.
Why a higher excess could be risky
You could face a bill you can't pay
If your excess is NZ$1,000 and you have no savings, an accident could leave you struggling to cover the excess, even if your insurer covers the rest of the repair.
The savings might be relatively small
If increasing your excess saves you NZ$100 a year, you'd need ten claim-free years to save NZ$1,000 in premiums. You might save more or less depending on your policy, and you could make a claim before then.
Insurance is there to protect your finances
Paying a little more each month for a lower excess can be worthwhile when you don't have a financial buffer. It reduces the amount you need to find in an already stressful situation.
What I'd do in your situation
- Keep the excess at the lowest affordable level. If you can manage the premium, avoid increasing the excess until you have some savings set aside. This is also the advice from Consumer NZ.
- Shop around before accepting a higher excess. Get quotes from at least three insurers, comparing both premiums and policy coverage. You might find a cheaper policy without taking on more risk. Car insurance buying guideCar insurance
- Start a small emergency fund. Even NZ$20 a week adds up to NZ$1,040 over a year. Once you've saved enough to cover your excess, you can reconsider increasing it.
- If the premium is genuinely unaffordable, compare your cover options. Depending on your car's value and your financial circumstances, third-party cover might be worth considering. Just understand that it generally won't cover damage to your own car. Car insurance buying guide
Let's work out whether the savings are worth the risk
If you tell me two numbers, I can help you compare the trade-off using your actual figures.
You don't need to have your finances perfectly sorted to make a good insurance decision. The goal is to keep your cover affordable without leaving yourself exposed to a bill you couldn't manage.
