Term insurance is life cover stripped of any savings element. You pay a premium and get a death benefit if you die during the term; if you outlive the term, nothing is paid. Because the insurer doesn't have to set aside a maturity reserve, term premiums are roughly 1/10th the cost of equivalent endowment cover.
A 30-year-old non-smoker can buy ₹1 crore of term cover for 30 years for around ₹10,000/year. The same person buying ₹1 crore of endowment cover would pay ₹3–5 lakh/year. For pure protection needs, term insurance is almost always the right answer; endowments make sense only if you specifically want the forced-savings discipline.
