What does an auto insurance underwriter do?

What is an auto insurance underwriter? Generally, an auto insurance underwriter calculates risk, but what do auto underwriters do?

What exactly do auto insurance underwriters look for?  Some of the specific roles and functions of auto insurance underwriters include:

  • Review information from the customer’s auto insurance application to determine the actual risk of insuring the customer
  • Determine the type of policy coverage to offer the client, including what auto insurance does not cover and under which conditions
  • Alter or restrict coverage using auto insurance endorsements (a special insurance policy provision that overrides other policy information)
  • Negotiate with your insurance broker or agent to add or remove certain policy coverage add-on options

FindLaw notes that insurance underwriters heavily rely on computer programs and their algorithms to evaluate what the driver’s risk will be to the insurance company, which is what determines policy rates.

An auto insurance underwriter is a trained professional. These professionals have years of experience assessing risk. They use this knowledge to determine whether or not to insure a driver.

What else do auto insurance underwriters look for, and what is the main function of an underwriter? Underwriters determine how much of a risk a person or group will be to the insurer. Insurance companies are in the business of making money, after all. 

Is it in the insurance company’s best interest to offer insurance to this person? How much should we charge this person for insurance based on the risk assessment? Auto insurance underwriters work to answer these questions every day.

The rates they determine are based on a wide variety of factors, so your rates may not be the same as your friend who lives outside of the city.

But you can get a general idea with this chart, which shows average rates across the country.

How does insurance underwriting work?

Underwriting insurance is the process of evaluating the risk of insuring a driver and a vehicle. Before you get an auto insurance policy from an insurance company, the company needs to complete the underwriting process.

During the underwriting process, the company will analyze your vehicle, your driving history, and other information. Based on this information, the insurance company will be able to calculate your auto insurance risk. Then, the insurance company charges you a premium based on your risk factor.

In many cases, the “insurance underwriter” is just a software program. On standard auto insurance policies, most underwriting can be performed automatically with underwriting software. For other policies, however, the underwriter might be human.

After determining risk

The underwriter or senior underwriter sets a price and establishes the insurance premium. The driver pays the premium. In exchange, the insurance company takes on the risk of covering the driver.

All of this takes place behind the scenes at an auto insurance company. After receiving an estimate online from GEICO, for example, you might proceed with buying your policy. Before the policy is finalized, however, an underwriter will verify the information you provided.

Insurance companies are for-profit organizations: the company is built to earn a profit. Underwriters help protect the bottom line of an auto insurance company by accepting the right insurance customers at the right price.

The main questions an auto insurance underwriter needs to answer are: what is the likelihood that this customer will make a claim that costs our auto insurance company money? How much should we charge this customer to ensure we make a profit while still offering competitive prices?

Underwriters play a similar role in home insurance and health insurance: they work behind the scenes to calculate the risk of each policyholder.

As a customer, you should do your own research. These top insurers in the country have good ratings, as you can see below.

Some Auto Insurance Underwriting is Automated

If you have a standard auto insurance policy, then your underwriting process may have been automated. A computer program might verify your information against public records, for example, before offering you auto insurance coverage.

Most auto insurance providers rely on automated underwriting systems. These systems are similar to the online quote application forms you see on our website or on an auto insurance provider’s website.

If you have a more complicated auto insurance policy, then it’s possible an underwriter will get involved. A human underwriter might get involved in the following situations:

  • You have multiple claims or incidents on your driving record
  • You have never purchased auto insurance to insure a new driver
  • There were issues processing your payment or verifying part of your record

If your policy gets flagged to be handled by an underwriter, it’s not a big deal. It just means it requires a little more effort than the computer can handle.

What is the difference between an underwriter and an agent or broker?

There are multiple groups involved with the auto insurance purchasing process for both monthly insurance and annual insurance, including auto insurance specialists like underwriters, agents, and brokers. These three parties might interact with one another regularly, but they all perform separate roles.

Think of the underwriter as the person behind-the-scenes. The underwriter receives an application and has to determine whether or not to offer car insurance to that person – and at what price.

The insurance agent and insurance broker, meanwhile, is the frontline salesperson: these are the people selling car insurance coverage to customers.

Agents do not typically have decision-making authority. Agents can offer auto insurance to clients who meet specific criteria. However, the agent is not typically able to alter the insurance policy outside of the boundaries of this agreement.

If a customer meets the basic criteria outlined in the underwriting manual, for example, then the customer might qualify for an auto insurance policy immediately. However, the agent is not typically able to “bend the rules” and change your policy without first consulting the insurance underwriter.
