Worked Examples
Income $80,000, mortgage $450,000, 2 dependants aged 5 and 8
Suggested cover: ~$1,490,000.
- Mortgage payoff: $450,000
- Income replacement: youngest child independent at ~18, so 13 years
- Income replacement: 13 x $80,000 = $1,137,000
- Total suggested cover: $450,000 + $1,137,000 = $1,490,000
- Offset by any savings/KiwiSaver balance to reduce required cover
Single person, income $60,000, no mortgage, no dependants

- No mortgage to cover
- No dependants — cover mainly for debt clearance and estate planning
- Rule of thumb: 10 x $60,000 = $600,000
- May reduce if minimal debts and substantial savings
