Below, we explore how math plays a vital role in the insurance industry, and how it helps both insurers and customers.

1. Measuring Risk

Risk is the probability of an event occurring that causes loss or damage.

Insurers use math to analyze data from various sources, such as historical records, surveys, statistics, and models, to estimate the frequency and severity of potential losses.

Insurers also use math to classify and segment customers based on their risk profiles, such as age, gender, health, occupation, location, and behaviour.

By measuring risk, they can determine how much they need to charge customers for their coverage, and how much they need to reserve for future claims.

2. Calculating Premiums

Premiums are the payments that customers make to purchase insurance policies.

Insurers use math to determine the fair and adequate amount of premiums that reflect the risk and the cost of providing insurance.

They use formulas and algorithms to calculate premiums based on various factors, such as the type and amount of coverage, the deductible, the coinsurance, the discounts, and the fees.

By calculating premiums, insurers can ensure that they collect enough revenue to cover their expenses and make a profit, while also offering competitive and cheap prices to customers.

3. Designing Policies

Policies are the contracts that specify the terms and conditions of the insurance coverage.

Insurers use math to create and customize policies that suit the needs and choices of different customers and markets.

They use math to define the scope and limits of the coverage, the exceptions, the benefits and features, and the obligations and rights of both parties.

By designing policies, insurers can offer a variety of products and services that cater to the diverse and changing demands of customers.

4. Evaluating Claims

Claims are the requests that customers make to receive compensation for their losses or damages.

Insurers use math to verify and process claims and to determine the amount and timing of the payments.

They use math to:

  • check the validity and accuracy of the claims
  • assess the extent and cause of the losses or damages
  • apply the relevant policy provisions and rules

By evaluating claims, they can fulfill their duties to customers, and also prevent and detect fraud and abuse.


Math is essential for the insurance industry, as it enables insurers to manage risk, price premiums, design policies, and evaluate claims.

Math also benefits customers, as it helps them to:

  • obtain enough cheap insurance coverage
  • receive fair and timely compensation for their losses or damages

It is the key to the success of the insurance industry, and it will continue to evolve as the industry faces new challenges and new chances.
