Percentage of claims settled by Car Insurance in a given year out of total claims is known as the claim settlement ratio. The higher the percentage of claims settled, the more credible the insurance provider becomes.
It is also advised that before purchasing any insurance, you should check the claim settlement ratios of all major companies on the Internet.

Know how is a claim settlement ratio calculated?
Claim Settlement Ratios CSR = (total number of claims settled in a year/total number of claims filed in a year) X 100
For example, if an insurance company settles 9000 claims out of a total of 10,000 claims, its CSR will be 90 percent.
