The most suitable sum insured depends on a variety of factors such as age, location, type of coverage, duration of cover, policyholder’s lifestyle and whether a general insurance company or life insurance company issues the policy. Generally, if you live in a small to midsized town, a cover of Rs.2-3 lakh should suffice while metro residents would need Rs.4-5 lakh.A health insurance comparison will help you decide which insurer offers the most suitable cover.
