Insurers don't pick premium numbers arbitrarily. They use actuarial models built on large data sets to estimate the probability of a claim — and then price the policy to cover that risk plus their operational costs and profit margin. Understanding the key inputs to that calculation helps you understand your own premium and what, if anything, you can do to influence it.
Age is the single most important factor. Mortality risk increases with age. A 25-year-old's premium might be half of a 40-year-old's for identical cover, tenure, and health profile. This is why age-based urgency in insurance conversations is genuinely valid — every year you wait costs you.
Gender matters statistically — women have lower mortality rates and therefore lower premiums. Several insurers including Kotak apply a 10–16% premium discount for female lives on term plans.
Health and medical history affects underwriting decisions significantly. Well-controlled chronic conditions may result in a loading (higher premium). Uncontrolled conditions or recent serious illness may result in postponement or decline. A clean bill of health gets the standard rate.
Smoking adds 50–120% to premiums depending on age and plan. Occupation — hazardous jobs like mining, deep sea diving, or aviation carry higher risk loadings. Sum assured affects the base premium amount. Policy tenure affects the total risk exposure priced into the policy.
The levers you can control: age (buy sooner), health (disclosure at good health stages, lifestyle improvements), smoking status (quit and get re-rated after 12 months), and occupation disclosure (some high-risk occupations can be reclassified with additional information).
