Insurance, by its nature, is meant to manage financial risk. But even with coverage, policyholders often have to share part of the burden. 

The idea behind excess in insurance was born because of this burden. It’s the amount that you need to pay out of your pocket before your chosen insurer contributes to a claim. 

There are two main types: compulsory excess and voluntary excess. These two might sound similar, but they play very different roles in insurance policies. 

The concept of compulsory excess

Compulsory excess refers to the type that is set specifically by the insurer. It is a fixed amount you must pay for any valid claim. You don’t have the option to change or negotiate it. 

Insurance providers decide this amount based on several factors. These may include the type of policy, the level of risk involved, and your claims history. For example, if you are a new driver or have made several past claims, your compulsory excess might be higher.

This type of excess is not meant to punish the policyholder. Instead, it is there to protect the insurer from small or frequent claims. It also encourages careful behaviour. 

If you know you’ll have to pay a certain amount every time, you may think twice before claiming insurance for minor issues. Compulsory excess is unavoidable. Even if you want full protection, this part is built into the policy.

The meaning of voluntary excess

Voluntary excess, as the name suggests, is an amount you choose to add on top of the compulsory excess. You can decide how much you are willing to pay in case of a claim.

Some policyholders opt for a higher voluntary excess to lower their monthly premiums. Others prefer to keep it low to avoid a large out-of-pocket cost later.

The key to voluntary excess is control. It gives you the power to shape your policy based on your financial comfort and risk appetite. 

If you rarely make claims and want to reduce your insurance bill, adding a voluntary excess can be smart. But it can backfire if an unexpected event leads to a big claim. Then, you’ll be paying more out of pocket before the insurer steps in.

How do the two work together?

Both types of excess apply when you file a claim. 

Let’s say your compulsory excess is $300, and you’ve set a voluntary excess of $200. If you make a claim, you must pay $500 in total before your insurer covers the rest. You can’t use one type to cancel out the other. They’re both calculated and added separately.

Choosing a voluntary excess doesn’t change the compulsory part. But together, they shape how much risk you share with the insurer. 

Why the distinction matters in specialized insurance

Understanding excess becomes even more important in more complex insurance types. 

Take the case of workers’ compensation policies as an example. Guaranteed cost workers’ comp is one such policy where premiums are fixed and not influenced by claim history. That means the insurer bears more of the risk, and the employer has predictable costs. However, even in this setup, excess still plays a role.

Compulsory excess ensures the employer remains partly responsible for small claims or minor work-related injuries. Voluntary excess, on the other hand, is rare in such setups.

Employers who want greater cost control without sharing risk usually avoid voluntary excess. But in high-deductible or self-insured models, choosing a voluntary amount can make sense.

When dealing with workers’ compensation, coverage limits and excesses must be handled carefully. According to Prescient National, workplaces carry significant risks, and one serious accident can lead to large claims and legal complications. If the excess amount is too high, it might strain the company’s resources during a crisis. 

A low excess might mean higher premiums, but better peace of mind. The decision must strike a balance between financial comfort and preparedness for unexpected events.

Risk perception and the role of excess

Your willingness to choose a voluntary excess says a lot about how you perceive risk. If you feel confident that your chances of filing a claim are low, you may be open to sharing more of the cost. That’s when voluntary excess becomes attractive. 

But if you’re in a high-risk situation, such as a business with physical labour, you may want to avoid extra exposure.

Insurers also assess risk before setting compulsory excess. A policyholder with a history of many claims may see this amount go up. Similarly, certain industries may have higher compulsory excess because the chances of claims are higher.

These amounts are part of a broader risk management plan. They reflect the insurer’s need to control exposure and maintain affordable premiums for everyone.

How excess and claims interact

When you file a claim, the total excess (compulsory plus voluntary) is the first amount you must pay. If the total cost of the incident is less than the combined excess, you won’t receive anything from the insurer. That’s why it’s vital to choose your voluntary excess wisely. It should never be more than you can realistically afford at short notice.

For businesses, this balance becomes even more critical. Claims related to employee injuries, property damage, or equipment loss can pile up quickly. Having a manageable excess structure ensures that the business remains financially stable after a claim is made.

Excess in insurance is more than a technical detail; it’s a financial decision. Compulsory excess is non-negotiable and reflects the insurer’s view of your risk level. Voluntary excess, on the other hand, is your own choice. It offers the chance to lower premiums, but also brings greater financial responsibility in a crisis.

Whether you’re protecting a personal vehicle or buying a guaranteed cost workers’ comp policy for your business, excess matters. It shapes your coverage, your costs, and your peace of mind.
