Insurance provides financial protection against a loss arising out of happening of an uncertain event. A person can avail this protection by paying premium to an insurance company.

A pool is created through contributions made by persons seeking to protect themselves from common risk. Premium is collected by insurance companies which also act as trustee to the pool. Any loss to the insured in case of happening of an uncertain event is paid out of this pool.
Insurance works on the basic principle of risk-sharing. A great advantage of insurance is that it spreads the risk of a few people over a large group of people exposed to risk of similar type.

Definition

Insurance is a contract between two parties whereby one party agrees to undertake the risk of another in exchange for consideration known as premium and promises to pay a fixed sum of money to the other party on happening of an uncertain event (death) or after the expiry of a certain period in case of life insurance or to indemnify the other party on happening of an uncertain event in case of general insurance.

The party bearing the risk is known as the insurer or assurer and the party whose risk is covered is known as the insured or assured.

Concept of Insurance / How Insurance Works

The concept behind insurance is that a group of people exposed to similar risk come together and make contributions towards formation of a pool of funds. In case a person actually suffers a loss on account of such risk, he is compensated out of the same pool of funds. Contribution to the pool is made by a group of people sharing common risks and collected by the insurance companies in the form of premiums.

WHY SHOULD I BUY INSURANCE?

All assets have some economic value attached to them. No person can deny that there is also a possibility that these assets may get damaged/destroyed or become non-operational due to risks like breakdowns, fire, floods, earthquake etc. Different assets are exposed to different types of risks like a car has a risk of theft or meeting an accident, a house is exposed to risk of catching fire, a human is exposed to risk of death/accident.

Social Security Tool

Insurance acts as an important tool providing a sense of security to the society on a whole. It is the right of every human-being to have basic amenities like food, clothing, housing, medical care, standard of living necessary for his personal and family is well being, and right to security in case of unemployment, disability, sickness or any other circumstances out of his control.

In case the bread earner of a family dies, the family suffers from direct financial loss as family is income ceases. As a result, family is economic condition gets affected unless there are other arrangements to rescue the family from this situation. Life insurance is one alternate arrangement that offers some respite to the family from financial distress. Otherwise this family would have been pushed into the lower strata of the society, which would be an additional cost to the society. This is because subsidies would have to be given to the family so as to enable it to survive and enjoy the basic rights at par with other people. Moreover, a poor family is generally seen to have a large family size with family members being illiterate. This on a whole affects the society and is a cost to the society. Therefore, insurance compliments the state in social management efforts.
