What is an Insurance Excess? How It Affects Your Wallet

When you get a quote for any policy in Australia, from your car to your home, there are two numbers that matter most: the premium and the insurance excess.

While most of us focus on the premium—the amount we pay each month or year—it’s the insurance excess that often determines how good our cover truly is in a crisis.

For many Aussies, this term is a source of confusion. It can feel like a hidden fee or a penalty you’re forced to pay when you’re already stressed from an accident, but its role is far more important than that.

The truth is, your excess isn’t a penalty at all. It’s a fundamental part of your insurance agreement that represents the amount of financial risk you agree to take on yourself.

Understanding the delicate balance between your excess and your premium is the single most powerful tool you have for controlling your insurance costs.

Getting this right can save you hundreds of dollars a year and protect you from unexpected financial shocks right when you’re most vulnerable.

This guide will break it all down in simple, no-jargon terms.

We’ll explain exactly what an insurance excess is, show you how it directly impacts your premium, walk you through how it works in real-life claim situations, and most importantly, help you figure out how to choose the perfect excess amount for your budget and peace of mind.

What is an ‘Excess’? Explaining the Basics Without the Jargon

At its core, an insurance excess is the fixed amount of money you agree to pay out of your own pocket towards a claim before your insurance company pays the rest.

Think of it as your contribution to the repair or replacement cost. Once you’ve paid your excess, the insurer covers the remaining costs, up to the limits of your policy.

Let’s use a simple analogy. Imagine you and a mate agree to split the cost of a large pizza. The pizza costs $30, and you both agree your “share” is the first $10.

You pay your $10, and your mate covers the remaining $20. The insurance excess works in exactly the same way.

For a real-world example, let’s say you have a comprehensive car insurance policy with a $700 excess. You accidentally reverse into a pole, and the repair bill from the smash repairer is $3,500.

• You pay the first $700 of the bill.
• Your insurer then pays the remaining $2,800.

This system exists for two main reasons. Firstly, it discourages people from making small, frequent claims. It wouldn’t make sense to claim for a $300 paint scratch if your excess is $700.

Secondly, it’s about sharing the risk. By agreeing to handle a small portion of any potential cost, you demonstrate to the insurer that you have a vested interest in staying safe and careful, which helps keep the overall cost of insurance down for everyone.

The Link Between Your Excess and Insurance Premium: How to Save Money

This is the most crucial part to understand because it’s where you can actively save money. Your excess and your premium have an inverse relationship—like a seesaw. When one goes up, the other comes down.

• A HIGHER Excess = A LOWER Premium: If you agree to pay more out of pocket in the event of a claim (e.g., a $1,200 excess), you are taking on more of the financial risk yourself. Your insurer sees this as less risky for them, so they reward you with a cheaper insurance policy. You’ll pay less each month or year.
• A LOWER Excess = A HIGHER Premium: If you prefer to pay less out of pocket when making a claim (e.g., a $400 excess), the insurer is taking on more of the potential risk. To compensate for this higher risk, they will charge you a more expensive premium. You’ll pay more each month or year for that extra security.

When and How Do You Actually Pay the Excess?

This is another area that often causes confusion. You don’t typically send a cheque to your insurance company. The process is much more integrated into the claim itself and usually happens in one of two ways.

The most common method, especially for car and home repairs, is paying the excess directly to the supplier or repairer. Let’s say your car is being fixed at a panel beater.

The total bill is $4,000 and your excess is $600. When you go to pick up your repaired car, you will pay the repair shop your $600 excess. They will then bill your insurance company for the remaining $3,400.

The second method is a deduction from your payout. This is common when an item is a total loss (your car is written off) or for contents insurance claims where you receive a cash settlement.

For example, if your $2,500 television was stolen and your contents insurance policy has a $300 excess, your insurer would pay you $2,200 ($2,500 minus your $300 excess).

A crucial exception to this is the not-at-fault accident. If you’re in a car accident and the other driver is entirely at fault, your insurer can often waive your excess.

This is conditional on you being able to identify the at-fault driver by providing their name, address, and vehicle registration number.

In this case, your insurer will pay for your repairs in full and then recover the entire cost from the other person’s insurance company.

Are There Different Types of Excess? (Spoiler: Yes!)

While you choose your main excess amount, it’s important to know that other excesses can sometimes be applied on top of it, depending on the situation and the driver. These are usually non-negotiable and are outlined in your policy’s Product Disclosure Statement (PDS).

Here are the most common types you’ll encounter in Australia:

• Standard Excess: This is the base amount we’ve been discussing. It’s the one you select when you take out your policy and applies to most claims.
• Voluntary Excess: This is an additional amount you can choose to add on top of the standard excess. Why would you do this? To lower your premium even further. It’s another lever you can pull to manage your insurance cost.
• Imposed or Age/Inexperience Excess: This is a big one for many families. Insurers see young or inexperienced drivers as higher risk. As a result, an additional, mandatory excess is often applied if a driver under 25 (or sometimes a driver of any age who has held their licence for less than two years) is behind the wheel during an accident. This can be very high, often $1,000 or more, and is added to your standard excess.
• Unlisted Driver Excess: Some policies require you to list all the regular drivers of your car. If someone who isn’t listed on your policy has an accident while driving your car, a high “unlisted driver excess” may apply on top of your standard excess.

How to Choose the Right Excess Amount for You

There is no single “best” excess amount; there is only the best amount for your circumstances. Choosing the right one is a balancing act between your monthly budget and your emergency savings.

The golden rule is this: Your excess should be an amount you can comfortably afford to pay at a moment’s notice without causing financial hardship or forcing you into debt.

To find your perfect number, ask yourself these questions:

• What’s in my emergency fund? Look at your savings. If you only have $1,000 saved for emergencies, choosing a $1,500 excess to save on your premium is a very risky strategy. A $500 or $800 excess would be a much safer choice.
• How likely am I to make a claim? Consider your personal history. Are you a very safe driver with a clean record who parks in a secure garage? You might feel comfortable with a higher excess. If you have a history of small accidents or park on a busy street, a lower excess might provide better peace of mind.
• Who drives my car? If you have a driver under 25 in your household, factor in the almost certain imposed age excess. You need to be prepared for the combined total.
• What is my personal risk tolerance? Are you the kind of person who sleeps better at night knowing you’re covered for almost everything, even if it costs a bit more? Or are you a calculated risk-taker who would rather save money now and trust in your ability to handle a larger one-off cost later?

A great practical step is to use online quote tools. When you get a quote from an insurer, play with the excess slider. Move it up and down and watch how the premium changes in real-time.

This will give you a clear picture of the savings on offer and help you find the sweet spot between an affordable premium and a manageable excess.

A Final Thought

The insurance excess is much more than just a piece of industry jargon buried in your policy documents. It is a dynamic tool that gives you direct control over what you pay for your cover.

By understanding the simple trade-off between the excess and the premium, you can move from being a passive price-taker to an active, informed consumer.

Before you renew your policy or sign up for a new one, take a moment to review the excess. Make sure it’s an amount that aligns with your current financial reality.

Choosing wisely won’t just save you money on your premium; it will give you the confidence that your insurance policy is a true safety net, ready to protect you without causing another financial headache when you need it most.
