With this loss ratio calculator, we are here to help you calculate and insurance company's underwriting loss ratio.

We wrote this article to help you understand what loss ratio is and how to calculate loss ratio. To assist you in understanding the concept, we will also demonstrate some loss ratio calculation examples. Without further ado, let's start by understanding what it is all about!

Loss ratio, or underwriting loss ratio, represents the ratio of the loss an insurance company makes to the total premium it earns from its policies. In particular, it tells you how much it cost the insurance company to pay the claims and expense of its policies compared to the premiums paid by the policies.

An insurance company's revenue comes mainly from its policies' premiums. When you buy insurance, you pay a certain amount of money every month for their services. This money is called the premium. On the other hand, the insurance company loses money when paying claims. For instance, if you buy insurance on your car and your car is damaged, you are allowed to claim at least part of the money back. Moreover, the insurance company needs to hire people to investigate and verify the claims. These expenses are called loss adjustment expenses. The loss ratio is the ratio of the sum of claims and loss adjustment expenses to the premiums earned. This can be thought of as the ratio of loss against the revenue of an insurance company.

Now, it's time to talk about the loss ratio formula and its calculation.

Let's take the insurance company below as an example to demonstrate the usage of the loss ratio calculator.

• Name: Company Alpha
• Total premiums earned: $10,000,000
• Insurance claims paid: $3,500,000
• Loss adjustment expenses: $1,800,000

There are 4 steps involved to properly use the loss ratio formula:

1. Determine the total premiums earned

   The premiums, or the total premiums earned, is the total amount of premiums paid to the insurance company by all its policies. In our example, the premiums for Company Alpha is $10,000,000.

2. Determine the insurance claims paid

   The claims, which stands for insurance claims paid, is the total amount of claims the insurance company has to pay to all of its policies. The claims for Company Alpha is $3,500,000.

3. Determine the loss adjustment expenses

   As explained above, the loss adjustment expenses, loss adj., are the expenses needed to validate the claims. In this example, the loss adj. for Company Alpha is $1,800,000.

4. Calculate the loss ratio

   Now we are ready to calculate the loss ratio. The loss ratio can be calculated using the equation below:

   loss ratio = (claims + loss adj.) / premiums

   The loss ratio for Company Alpha is ($3,500,000 + $1,800,000) / $10,000,000 = 53%.

It is not difficult at all to understand and interpret the underwriting loss ratio after you've found it with our loss ratio calculator. There are three points that you should focus on:

• If the loss ratio is larger than 100%, it means that the insurance company's total claims and expenses for its policies are more than the total premiums. It indicates that the insurance company is making a loss on its policies.
• If the loss ratio is equal to 100%, the insurance company's claims and expenses are equal to the premiums it earns. Hence, it is breaking even in its business.
• A loss ratio of lower than 100% indicates that the insurance company has a profitable business and operation since the total claims and expenses are less than the premiums the company earns.
