Before you subscribe an insurance you need to understand how insurance companies work. To help understand that we have provided a detailed explanation of Insurance Companies Business Model based on internet research and talking with some friends that are experts and work on the insurance professional field. Let’s breakdown the model in components:
- Underwriting and investing
Underwriting and investing
On raw terms we can say that the Insurance Companies business model is to bring together more value in premium and investment income than the value that is expended in losses and at the same time to present a reasonable price which the clients will accept.
The earnings can be described by the following formula:
Earnings = earned premium + investment income – incurred loss – underwriting expenses.
Insurance Companies gain their wealth with these two methods:
- Underwriting, is the process that Insurance companies use to select the risk to be insured and chooses the value of the premiums to be charged for accepting those risks.
- Investing the values received on premiums.
There is a complex side aspect on the Insurance Companies business model that is the actuarial science of price setting, based on statistics and probability to estimate the value of future claims within a given risk. Following the price setting, the insurance company will consent or refuse the risks using the underwriting process.
Taking a look at the frequency and severity of the insured liabilities and estimated payment average is what ratemaking at a simple level is. What companies do is check all those historical data concerning losses they had and update it on today’s values and then comparing it to the premiums earned for a rate adequacy assessment. Companies use also expense load and loss ratios. Simply putting this we can say that the comparison of losses with loss relativities is how rating different risks characteristics are done. For example a policy with the double losses should charge a premium with the double value. Of course there is space for more complexes calculations with multivariable analysis and parametric calculation, always taking data history as it inputs to be used on the probability of future losses assessment.
The companies underwriting profit is the amount of premium value collected when the policy ends minus the amount of paid value on claims. Also we have the underwriting performance A.K.A. the combined ratio. This is measured by dividing the losses and expenses values by the premium values. If it is over 100% we call it underwriting loss and if it is below the 100% then we call it the underwriting profit. Don’t forget as part of the Companies business model there is the investment part which means that the companies can have profit even with the existence of underwriting losses.

The Float is how insurance companies earn their investment profits. It is amount of value collected in premium within a given time and that has not paid out in claims. The investment of the float starts when the insurance companies receive the payments from the premiums and end when the claims are paid out. As it is this time frame is the duration from which the interest is earned.
The insurance companies from the United States that operate on casualty and property insurance had an underwriting loss of $142 Billion in the five years ending on the year of 2003, and for the same period had an overall profit of $68 Billion consequence of the float. Many professionals from the industry think that is possible to always achieve profit from the float not having necessarily a underwriting profit. Of course there are many thinking streams on this matter.
