When it comes to insurance, companies assess risk based on two key factors: the frequency of claims and their severity. Severity refers to the amount of damage that is (or may be) inflicted by a loss or catastrophe. This is quantified as a severity rate, which is a ratio relating the amount of loss to values exposed to loss during a specified period. In the context of auto insurance, severity is reflected in the amount paid per claim, while frequency refers to the number of crashes and how often they occur. For example, a house fire is a catastrophic event that usually leads to a high-severity insurance claim. However, if it is an isolated incident, insurers may still view the policyholder favourably and not decline their insurance application.
| Characteristics | Values |
|---|---|
| Definition | Severity refers to the amount of damage that is (or may be) inflicted by a loss or catastrophe. |
| Calculation | Average severity is calculated by dividing the total losses by the number of claims made. |
| Pure Premium | Calculated by multiplying frequency by severity, the pure premium represents the amount of money the insurer will need to pay in estimated losses over the life of the policy. |
| Factors | The models used to predict future claims and losses depend on the type of risk being insured, the demographic and geographic information of the individual or business, and the number of claims made. |
| Insurable Risk | Insurers usually cover pure risks, such as property damage, and rarely cover speculative risks, such as gambling and investing. |
| Pure Risk Examples | Natural events (fires, floods), accidents (car crashes, sports injuries), personal risks, property risks, and liability risks. |
| Insurable Risk Elements | Due to chance, measurable and definite, predictability, non-catastrophic, random selection, and large loss exposure. |
| Frequency vs. Severity | High-severity claims, while costly, can be insurable if they are rare. A high frequency of claims, even if low in severity, can lead to higher premiums or difficulty obtaining coverage. |

Pure risk vs. speculative risk
Risk is an inherent part of any insurance contract, and understanding the different types of risks is crucial for both insurers and policyholders. One way to categorize risks is by distinguishing between pure risk and speculative risk. While both types of risks involve uncertainty and the possibility of loss, they differ in terms of the potential for gain and the underlying motives of the individuals or entities involved.
Pure risk, as the name suggests, involves the possibility of only loss or no loss. In other words, there is no potential for gain beyond the avoidance of loss. Natural disasters, fires, accidents, theft, and death are all examples of pure risks. For instance, a homeowner faces the pure risk of their house being damaged or destroyed by a fire. Purchasing insurance to protect against this risk transfers the financial burden of the loss from the homeowner to the insurance company. In this case, the homeowner is solely interested in mitigating potential losses and is not motivated by the prospect of financial gain.
On the other hand, speculative risk involves situations where there is a possibility of both loss and gain. These risks are often associated with speculative activities such as investing in the stock market, starting a new business, or engaging in gambling. For example, an individual who invests in stocks may experience a gain if the stock price increases or a loss if the price declines. Here, the individual is taking on speculative risk with the motive of generating a financial return. While the potential for gain exists, so too does the potential for loss, and this uncertainty defines speculative risk.
Another key distinction between pure and speculative risk lies in their treatment by insurance companies. Pure risks are typically insurable, as they are beyond the control of the individuals or entities involved and have a predictable probability of occurrence. Insurers can use historical data and statistical analysis to assess the likelihood of a pure risk event occurring and set premiums accordingly. On the other hand, speculative risks are generally not insurable because they are often influenced by the actions of the insured party and involve unpredictable outcomes.
It is important to note that the distinction between pure and speculative risk is not always clear-cut, and some risks may exhibit characteristics of both types. Additionally, the perception of a risk as pure or speculative can vary depending on the perspective of the individuals involved. For example, an entrepreneur starting a new business may view the risk as speculative, as there is a chance of generating profits along with the risk of loss. However, a lender providing a loan to the same business may view the risk as pure, as they are only concerned with the possibility of loan default and are not motivated by the potential for financial gain.
Understanding the difference between pure risk and speculative risk is essential for making informed decisions in insurance and risk management. By recognizing the unique characteristics and implications of each type of risk, individuals, businesses, and insurers can develop strategies to mitigate potential losses and protect their financial interests.

Average severity
For example, let's consider a scenario where an insurance company has received a total of $1,000,000 in losses from various claims. If the number of claims made during that period was 100, the average severity would be $10,000 ($1,000,000 divided by 100 claims). This means that, on average, each claim costs the insurance company $10,000.
Insurance companies rely on actuaries and their models to predict future claims and the associated losses. These models take into account various factors, such as the type of risk being insured, demographic and geographic information, and claim history. By analyzing past data and trends, insurance companies can estimate the average severity of future claims and set their premiums accordingly.
In summary, average severity is a key metric used by insurance companies to assess the average cost of claims. It helps them set premiums, predict future losses, and make informed decisions about their policyholders' risk profiles. By understanding average severity, insurance providers can balance their risk exposure and ensure the sustainability of their business while providing coverage for their customers.

Predictability
Insurance companies rely on actuaries and their models to predict future claims and associated losses. These predictions are based on statistical analysis, historical data, and various factors such as the type of risk, demographic and geographic information, and claim frequency. By understanding the likelihood and potential impact of future claims, insurers can set premiums accordingly to ensure profitability.
Insurers are generally more comfortable with infrequent, high-severity claims compared to a high frequency of low-severity claims. This is because a high number of small claims suggests a greater likelihood of future large claims. For example, a business with frequent vehicle accidents may indicate unsafe practices, increasing the chances of more severe accidents in the future.
Additionally, high-frequency, low-severity claims can lead to higher premiums or difficulty in obtaining coverage. This is because insurers assume that a high claim frequency indicates an increased risk of future large claims. As a result, policyholders who make infrequent claims are often viewed more favourably and are more likely to have their policies renewed.
In summary, predictability in insurance involves assessing the likelihood of future claims and their severity. Insurance companies use statistical analysis and historical data to make these predictions, which helps them set premiums and manage their risk exposure. By understanding these factors, policyholders can make informed decisions to maintain a favourable risk profile and secure competitive rates.

Severity rate
Insurers rely on actuaries and their models to predict future claims and the associated losses. By understanding the severity rate, insurers can set premiums at a level that allows them to break even or make a profit. The pure premium, which is calculated by multiplying frequency by severity, represents the estimated losses an insurer will need to pay over the life of a policy.
When assessing risk, insurers consider the frequency of claims alongside severity. While a high-severity claim can be costly, it may be insurable if it occurs infrequently. On the other hand, a high frequency of claims, even if they are low in severity, can lead to higher premiums and difficulties in obtaining coverage. This is because a high number of small claims indicates a greater chance of a large claim occurring in the future.
The severity rate is also influenced by the type of risk being insured. Pure risks, such as property damage, natural disasters, or accidents, are typically covered by insurers. These risks are uncertain situations with the potential for loss but no opportunity for financial gain. Speculative risks, like gambling or investing, are rarely covered by insurers as they may result in either a profit or a loss.
By understanding severity rates and how they impact insurance premiums, policyholders can make more informed decisions about their coverage. Additionally, implementing risk management techniques can help reduce the frequency and severity of accidents, leading to lower premiums. Overall, severity rate plays a crucial role in the insurance industry, guiding insurers in their pricing and coverage decisions and helping policyholders make strategic choices about their insurance protection.

Pure premium
Insurers use actuarial studies and models to predict future claims and the potential losses from those claims. These models take into account various factors, including the type of risk being insured, demographic and geographic information about the policyholder, and the number of claims made. By analysing this data, insurers can estimate the amount of loss they should expect from the average claim and set their premiums accordingly.
The pure premium is an essential component of the overall premium charged to the customer. Once the pure premium is calculated, a loading charge is added to cover other expenses, such as sales expenses, and to allow the insurer to make a profit. This final premium is known as the gross premium and is what the insurance applicant is charged.
Understanding the concept of pure premium provides valuable insights into how the insurance industry operates and how premiums are set. It also highlights the importance of accurate data analysis and modelling in ensuring the financial stability of insurance companies and their ability to pay out claims.

Frequently asked questions
Severity refers to the amount of damage that is (or may be) inflicted by a loss or catastrophe. This is often quantified as a severity rate, which is the ratio of the amount of loss to the values exposed to loss during a given period.
The pure premium, calculated by multiplying frequency by severity, represents the amount of money the insurer will need to pay in estimated losses over the life of the policy. Insurance companies use this information to determine the premiums they must charge to break even. A high severity claim, while expensive, can be insurable if it occurs rarely.
High-severity, insurable events are usually pure risks, which include natural events such as fires or floods, or accidents such as automobile crashes. These events are insurable because they are definite and measurable, statistically predictable, and non-catastrophic.
