What Is the Combined Ratio?
Let me explain the combined ratio directly: it's a key metric that shows how much an insurance company spends on claims and expenses relative to its earned premiums. You calculate it by adding up incurred losses and expenses, then dividing that total by the earned premium.
Key Takeaways
As someone diving into insurance metrics, you should know the combined ratio measures profitability in daily operations for insurance companies. It's expressed as a percentage, and if it's below 100%, the company is turning an underwriting profit; above 100%, it's paying out more in claims than it collects in premiums. Many in the industry see it as the top way to gauge success because it ignores investment income and focuses on profits from smart management.
The Formula for the Combined Ratio
Here's the straightforward formula you need: Combined Ratio = (Incurred Losses + Expenses) / Earned Premium. This gives you the percentage that tells the story of operational efficiency.
What Does the Combined Ratio Tell You?
When you look at the combined ratio, it reveals the outflow of money from an insurance company through dividends, expenses, and losses. The losses part shows the insurer's discipline in underwriting policies, while the expense ratio highlights efficiency in using resources for growth. Overall, this ratio is crucial because it offers a full picture of profitability. Remember, it's a percentage: below 100% means underwriting profit, above means more payouts than premiums. Even with a ratio over 100%, profitability might still exist from investments, but the combined ratio deliberately excludes that to emphasize management efficiency. That's why many companies prefer it—it focuses on core operations, not investments in stocks or bonds. For a broader view, there's the investment income ratio, which feeds into the overall operating ratio.
Examples of the Combined Ratio
Consider this hypothetical: if an insurer collects $1,000 in premiums and pays $800 in claims plus $150 in operating expenses, the combined ratio is (800 + 150) / 1,000 = 95%. That's a profit indicator. Now, take insurance company ZYX with underwriting expenses of $10 million, losses and adjustments of $15 million, net written premiums of $30 million, and earned premiums of $25 million. On a financial basis, the combined ratio is ($10 million + $15 million) / $25 million = 100%, showing break-even. For the trade basis, it's ($15 million / $25 million) + ($10 million / $30 million) = 93%, which suggests better efficiency.
The Difference Between the Combined Ratio and the Loss Ratio
You might confuse it with the loss ratio, but here's the distinction: the loss ratio looks at total incurred losses against collected premiums, while the combined ratio adds in expenses to that mix. Essentially, combined ratio = loss ratio + expense ratio. The loss ratio is incurred losses divided by premiums; a low ratio means profitability, but over 100% signals potential financial trouble from excessive payouts.
Limitations of the Combined Ratio
Don't rely on the combined ratio alone; its components—losses and expenses—each reveal different aspects and need separate review to understand profitability drivers. Dividends come from underwriting premiums, the loss-adjustment ratio shows the cost of providing protection per dollar, and the expense ratio covers costs like commissions and overhead. Examine them together and apart for the full story.
