The penalty is twofold: cost and eligibility. If you buy at 25, you might pay Rs 8,000 yearly. Wait until 35, and that jumps to roughly Rs 15,000 for the same cover. Over 30 years, you are looking at an extra Rs 2.1 lakh out of pocket just for delaying. “More importantly, lifestyle diseases like diabetes or hypertension often creep in by your 30s. This could either double your premium again or, worse, make you completely uninsurable," says Joshi. Remember that, unlike health insurance, your term insurance premium remains constant for the entire term. So the earlier you take it, the better.
