About Group Insurance Cost Calculator

Group health premium is driven far more by family-cover uptake than by headcount, because adding a spouse, children and often parents roughly doubles the per-employee cost. Modelling uptake explicitly is essential to any benefits budget.

Formulas

Total premium

Total = Single-cover employees x Premium + Family-cover employees x Premium x (1 + Family loading %)

Average cost

Average = Total premium / Number of employees

Frequently Asked Questions

Why is group cover cheaper than individual?

Because the group is a pre-existing pool with no anti-selection, underwriting is minimal or nil, and administration is centralised.

Should employees contribute to family cover?

Many employers fund employee-only cover and offer family cover on a contributory basis, which controls cost while preserving choice.
