**Basics of Ratemaking:**
Insurance involves transferring risk to the insurer, allowing the insured to mitigate financial losses from covered perils. To determine the price of insurance (rate), insurers must consider future claims, expenses, and profit margins.
A rate is the price per unit of insurance (e.g., Rs.1.00 per mile for earthquake coverage) and is based on past trends and current factors. It's important to note that rates differ from premiums.
**Premium Calculation:** Premium = (Sum Insured) x (Rate).
**Example 1:** In health insurance, risks are assessed based on age, race, occupation, and lifestyle, and these factors are scored numerically. The premium amount hinges on:
(i) Probability of loss due to insured risk. (ii) Estimated loss amount from the event.
**Example 2:** For a house valued at Rs. 1,00,000, if the probability of fire destruction is 1 out of 100 (0.01), the expected average loss is Rs. 1,000 (Rs. 1,00,000 x 0.01). Therefore, insurers need to charge at least Rs. 1,000.
To cover actual losses, insurers pool various risks, relying on the law of large numbers, which suggests that larger sample sizes yield more predictable results. For instance, tossing a coin many times will yield nearly equal results of heads and tails, unlike a single toss.
**Example 3:** In property insurance, wooden structures have a higher fire risk than stone ones, necessitating higher premiums. This principle also applies to life and health insurance, where individuals with conditions such as high blood pressure face higher premiums.
