Combined Ratio: How it Works, Formula, and Examples
Summary:
The combined ratio is a key metric used by insurance companies to evaluate their underwriting profitability by comparing losses and expenses to earned premiums. A combined ratio below 100% indicates that the insurer is operating at a profit, while a ratio above 100% suggests that the company is paying out more in claims and expenses than it is earning. This ratio focuses purely on core business operations, excluding investment income.
What is the combined ratio?
The combined ratio, also known as the combined ratio after policyholder dividends, is a performance metric widely used by insurance companies. It calculates the relationship between incurred losses, underwriting expenses, and earned premiums. This percentage-based ratio allows insurers to determine how efficiently they are managing claims and operational costs, helping to assess the financial health of their underwriting business.
In simpler terms, the combined ratio compares the money flowing out of an insurance company (claims and expenses) to the money coming in (premiums). If the ratio is below 100%, it means the company is earning a profit from its underwriting operations. A ratio above 100% suggests that the company is paying out more in claims and expenses than it receives in premiums, which could indicate poor financial performance in the core insurance operations.
Formula for the combined ratio
The formula for calculating the combined ratio is straightforward. It is the sum of an insurer’s incurred losses and expenses divided by its earned premiums:
This formula highlights the two major components involved: incurred losses (which include claim payouts) and expenses (which refer to underwriting, administrative, and operational costs). The earned premium is the revenue generated from policies during the period, serving as the denominator.
Understanding the components of the combined ratio
Incurred losses: These represent the total claims paid out by the insurer during the policy period. It reflects the insurer’s discipline in managing risk and underwriting policies effectively.
Expenses: This includes administrative costs, commissions, operational overheads, and other expenses incurred while managing insurance policies. Keeping these expenses low is a sign of operational efficiency.
Earned premium: The amount of premiums an insurer earns from its customers after the policy period begins. This figure accounts for the portion of premiums already recognized as revenue by the company.
How to interpret the combined ratio
In practice, the combined ratio is expressed as a percentage. When the combined ratio is below 100%, it means the insurer is generating a profit from its underwriting activities. A ratio above 100% suggests that the company is paying out more in claims and operational expenses than it is receiving in premiums, which could lead to financial strain.
For example, a combined ratio of 95% means that for every $1 collected in premiums, the company spends 95 cents on claims and expenses, leaving 5 cents as profit from underwriting. On the other hand, a combined ratio of 110% indicates that the insurer is losing money, as it is paying out $1.10 for every $1 earned in premiums.
Examples of the combined ratio in practice
Consider an insurance company that collects $1,000 in premiums. If it pays out $800 in claims and incurs an additional $150 in operational expenses, the combined ratio would be calculated as follows:
This result shows that the insurer is running a profitable underwriting operation since its combined ratio is below 100%. Another real-world example involves a larger company with $15 million in incurred losses, $10 million in expenses, and $30 million in earned premiums:
Here, the insurer is operating efficiently, keeping both its losses and expenses well within the premiums earned, indicating strong profitability in its core business.
Combined ratio vs. loss ratio
The combined ratio is often compared with the loss ratio, which solely measures the relationship between incurred losses and earned premiums. While the loss ratio focuses on the insurer’s underwriting performance (how much it pays out in claims), the combined ratio includes both losses and operational expenses.
For instance, if an insurance company has $5 million in incurred losses and $10 million in earned premiums, the loss ratio would be calculated as:
However, to gain a fuller picture of profitability, the combined ratio considers the company’s operational expenses in addition to losses. This makes the combined ratio a more comprehensive measure of an insurer’s overall profitability.
Why the combined ratio matters
The combined ratio provides key insights into an insurer’s profitability and efficiency. Unlike other financial metrics that may be skewed by investment income or one-time financial gains, the combined ratio focuses solely on the insurer’s core underwriting business. It highlights how well the company is managing risks, claims, and expenses while delivering protection to policyholders.
Insurance companies often rely on the combined ratio as a primary metric because it excludes investment income and focuses strictly on how efficiently the company operates its insurance business. It forces insurers to optimize their underwriting practices to ensure long-term sustainability and profitability.
Limitations of the combined ratio
Although the combined ratio is a valuable measure of profitability, it has its limitations. It does not take into account investment income, which can be a significant source of profit for many insurers. A company may have a combined ratio above 100% but still be profitable due to strong returns on investments.
Moreover, the combined ratio does not reflect the quality of underwriting practices. A low ratio might suggest profitability, but it could also indicate overly conservative underwriting that limits growth opportunities. Therefore, the combined ratio should be analyzed alongside other financial metrics such as the investment income ratio or operating ratio to gain a complete picture of an insurer’s financial performance.
Understanding the expense ratio component
The expense ratio is an important part of the combined ratio, representing the percentage of premium income used to cover an insurer’s administrative and operational costs. These expenses typically include employee salaries, commissions to agents, office overhead, and marketing costs. A lower expense ratio indicates greater efficiency in managing operational costs, which in turn helps lower the overall combined ratio. Insurers strive to keep this ratio low to ensure that more of their earned premiums go toward underwriting profits rather than operational expenses.
Incurred losses and their impact on the combined ratio
Incurred losses refer to the total claim payments made by an insurer, including expenses related to adjusting and settling claims. This is a major component of the combined ratio, as it reflects the insurer’s ability to underwrite policies effectively. High incurred losses can drive up the combined ratio, indicating that the company may be overexposed to risk or facing higher-than-expected claim payouts. Efficient underwriting practices that minimize incurred losses help maintain a healthy combined ratio and contribute to the insurer’s profitability.
The role of policyholder dividends in the combined ratio
Policyholder dividends, though not part of every insurance company’s operations, can also influence the combined ratio. These are typically paid out by mutual insurance companies to their policyholders when the company has performed better than expected. If an insurer issues dividends, they are factored into the combined ratio, adding to the company’s expenses. Although these dividends are a sign of financial health, they can push the combined ratio higher, which may not necessarily indicate poor operational performance.
Trade basis combined ratio vs. financial basis combined ratio
The combined ratio can be calculated on both a trade basis and a financial basis. The trade basis combined ratio includes adjustments for reinsurance and typically gives a more comprehensive view of an insurer’s performance. Meanwhile, the financial basis combined ratio is based solely on statutory financial statements and provides a snapshot of the company’s profitability during a specific period. Insurers often use both methods to get a complete picture of their financial health and underwriting efficiency.
How to improve the combined ratio
Insurance companies can improve their combined ratio by focusing on several key areas. Reducing operational expenses, tightening underwriting guidelines, and implementing better risk management strategies can help lower incurred losses and expenses. Additionally, insurers can look for ways to streamline administrative processes and reduce overhead costs. By improving these aspects of the business, companies can ensure that more of their premiums translate into profits rather than being spent on claims and expenses.
Conclusion
The combined ratio is a critical metric for assessing an insurance company’s underwriting performance and operational efficiency. By providing a clear snapshot of how well an insurer is managing its core operations, the combined ratio helps both the company and its stakeholders gauge profitability. While a ratio below 100% indicates profit, a ratio above 100% suggests that the insurer is paying out more in claims and expenses than it earns from premiums. However, investment income, which is excluded from the combined ratio, can also play a significant role in the overall profitability of an insurer. Therefore, the combined ratio should be considered alongside other financial metrics to get a full picture of the company’s financial health.
Frequently asked questions
What is the purpose of the combined ratio in insurance?
The combined ratio is used by insurance companies to assess their underwriting profitability. It measures how efficiently the company is managing claims and expenses in relation to the premiums it earns. This ratio helps insurers gauge whether their core insurance business is generating profit without relying on investment income.
How do you calculate the combined ratio?
The combined ratio is calculated using the following formula:
This formula adds the incurred losses and operational expenses of the insurer and divides that sum by the total earned premium during the period.
What does a combined ratio of 100% signify?
A combined ratio of 100% means that the insurance company is breaking even on its underwriting operations. It is neither making a profit nor a loss, as the premiums earned exactly match the total claims and operational expenses. Insurers aim to keep this ratio below 100% to ensure profitability.
Why is the combined ratio important for insurers?
The combined ratio is important because it provides a clear picture of how well an insurer is managing its core business operations. Unlike other financial metrics, the combined ratio focuses strictly on underwriting efficiency, excluding investment income, and shows whether the company is profitable from its insurance activities.
Can a company still be profitable with a combined ratio over 100%?
Yes, an insurance company can still be profitable with a combined ratio over 100% if it has substantial investment income. Although the combined ratio reflects losses in underwriting, insurers often invest a portion of their income in bonds, equities, and other securities, which can offset underwriting losses and lead to overall profitability.
What factors can influence the combined ratio?
Several factors can affect the combined ratio, including claim frequency and severity, operational efficiency, expense management, and underwriting practices. A high number of claims or significant underwriting losses will push the ratio higher, while effective risk management and cost control can lower the ratio.
