How is group term life insurance premium calculated?
A group term life premium is broadly the total sum assured across all members multiplied by a mortality rate that reflects the group’s age profile, then adjusted for occupation risk, group size and past claims. Insurers usually express it as a single average rate per ₹1,000 of cover for the whole scheme, so the premium rises with sum assured and the average age of the team.

A group term life premium is broadly the total sum assured across all members multiplied by a mortality rate that reflects the group’s age profile, then adjusted for occupation risk, group size and past claims. Insurers usually express it as a single average rate per ₹1,000 of cover for the whole scheme, so the premium rises with sum assured and the average age of the team.
The five things that move the premium
A group term life rate is not a mystery — it comes down to how much cover is at risk and how likely a claim is across your team.
| Driver | How it affects the premium |
|---|---|
| Total sum assured | The premium scales directly with the total cover across all members. |
| Age profile of the group | Mortality rates rise with age — an older team costs more per ₹1,000 of cover. |
| Occupation / risk class | Higher-risk roles (field, manufacturing, logistics) attract a higher rate. |
| Group size | Larger groups pool risk better and often get a keener rate and higher free cover limit. |
| Claims experience | Past claims under the scheme feed into the renewal rate, up or down. |
A simplified worked example
Suppose a scheme covers 50 employees with a total sum assured of ₹50,00,00,000 (₹1 crore average cover each) and the insurer sets a blended rate of ₹1.20 per ₹1,000 of cover for the group’s age and occupation profile:
| Total sum assured (50 × ₹1,00,00,000) | ₹50,00,00,000 |
| Rate per ₹1,000 of cover | ₹1.20 |
| Annual risk premium (SA ÷ 1,000 × rate) | ₹6,00,000 |
| Add GST at 18% | ₹1,08,000 |
| Total annual premium | ₹7,08,000 |
That works out to roughly ₹14,160 per employee for the year on average — but it is an average. The underlying rate is age-weighted, so an older team would pay a higher rate per ₹1,000 and a younger team less. The figures here are illustrative; your actual rate depends on your team’s exact profile and the insurer’s assessment.
How the calculation is built up
The same four steps sit behind every group term life quote.
Start with the total sum assured
The insurer adds up the sum assured for every covered employee. This is the total amount at risk, and the premium is a rate applied to it — so if you double the cover, you broadly double the premium, all else equal.
Apply a mortality rate driven by age
The rate per ₹1,000 of cover reflects the probability of death across the group, which is dominated by the age profile. A young team is cheaper per rupee of cover than an older one. Insurers typically blend this into one average rate for the whole scheme rather than pricing each person separately.
Adjust for occupation, size and history
The base rate is loaded for occupation risk (a field-heavy team costs more than a desk-based one), softened for a larger group that pools risk well, and revised at renewal in light of the scheme’s own claims experience.
Add taxes and read the per-employee cost
GST is added on top of the risk premium. Dividing the total by headcount gives an average per-employee cost, but remember it is an average — the underlying risk is age-weighted, so two teams of the same size can price differently.
Frequently asked questions
What is the single biggest driver of GTL premium?
The combination of total sum assured and the group’s age profile. The sum assured sets how much is at risk, and the age profile sets the mortality rate applied to it. An older team with high cover will always cost more than a young team with modest cover, even at the same headcount.
Is each employee priced individually?
Usually not. Group term life is typically priced at a single average rate per ₹1,000 of cover for the whole scheme, based on the group’s overall age and risk profile. That is what makes it simpler and cheaper to administer than individual term insurance, where every person is underwritten separately.
Does a bigger team make GTL cheaper per employee?
Often, yes. A larger group pools mortality risk more predictably, which can earn a keener rate and a higher free cover limit, so more employees are covered without medical tests. Age profile still matters — size helps, but it does not override an older team’s higher underlying mortality rate.
How does occupation affect the premium?
Insurers classify occupations by risk. Predominantly desk-based teams sit in the lowest-risk class and attract the lowest rate; field sales, logistics, manufacturing and on-site roles carry more risk and a higher rate. A mixed team is priced on its overall blend.
Can I estimate the cost before getting a quote?
You can get a rough sense: total sum assured × an age-weighted rate per ₹1,000, plus GST. But because the rate depends on your team’s exact age and occupation mix and the insurer’s view of the group, a quote is the only way to get an accurate figure. Onsurity can price it for your specific team.
