How much life cover do I need?
There's no single right number, but a widely-used starting point is the LIFE method, which adds up what your family would actually need if you passed away, then subtracts the cover you already have. LIFE stands for Liabilities, Income replacement, Final expenses, and Education.
L, for liabilities
The debts that would need settling: your home loan, vehicle finance, and personal loans. Clearing these means your family isn't left servicing them on a smaller income.
I, for income replacement
The biggest piece for most people. The idea is to provide a lump sum that, invested sensibly, replaces the income your household relied on, for a chosen number of years (often until retirement). A common refinement is to base it on the household's expenses rather than gross income (a survivor typically needs around 80% of prior expenses), and to exclude debt repayments that are already covered under Liabilities, so you don't count them twice.
This number is sensitive to two assumptions: the return you expect on the lump sum, and how many years it has to last. A lower assumed return, or a longer period, pushes the cover you need up, sometimes by a lot.
F, for final expenses
Immediate costs at death: funeral costs and the executor's fee (in South Africa, up to 3.5% of the estate's assets, plus VAT), and any estate duty. Having cash for these means assets don't have to be sold in a hurry.
E, for education
The cost of seeing your children through school and tertiary education, often one of the largest long-term commitments a family has.
A worked example
Take a parent with a partner and two young children:
- Liabilities: a R900,000 bond and R150,000 on the car = R1,050,000.
- Income replacement: enough capital to replace the household's income for the years to retirement, say R4,000,000.
- Final expenses: funeral plus executor's fee and duty, roughly R250,000.
- Education: two children at about R500,000 each = R1,000,000.
That's a need of about R6,300,000. Subtract existing cover of, say, R2,000,000, and the gap to consider is roughly R4,300,000. The figure is only as good as the assumptions, so treat it as a starting point to refine.
Term or whole-of-life?
Most people meet a need like this with term cover, which pays out if you die within a set period and is the cheaper way to buy a large sum while you have dependants and debt. Whole-of-life cover lasts for life and costs more, and tends to be used for permanent needs like leaving a guaranteed legacy or covering estate duty. For pure income protection during your working years, term usually does the job.
When to review it
Your need moves with your life, so revisit the number after the big changes:
- A new baby or a new bond pushes it up.
- Paying off debt or your children finishing their education pulls it down.
- Marriage, divorce, or a large change in income can swing it either way.
Common questions
How much do I actually need?
There's no one figure. Run the LIFE method on your own numbers; for a family with a bond and children it often lands in the millions.
Will my family pay tax on the payout?
A payout to a nominated beneficiary is generally free of income tax in their hands, though estate duty can apply depending on how the policy is structured.
How often should I check it?
After any major life event, and otherwise every couple of years.
