Worked calculation structure
A motor premium calculation can be reviewed as a sequence rather than one unexplained total: establish the applicable vehicle value or IDV, calculate the relevant OD component, apply applicable discounts such as NCB, add TP and selected covers, then calculate GST on the applicable premium total. Exact rates and eligibility depend on the vehicle, product, insurer and current rules.
Important calculation note
Verify current insurer rates, product rules, tariff requirements and the final policy schedule before relying on a premium result.
