Life insurance exists to answer one brutal question: if your income stopped tomorrow, would the people who depend on it be all right? Everything else — the product names, the riders, the sales scripts — is detail on top of that question. And yet the industry has built two very different products around it, term and whole life, whose costs can differ by a factor of ten for the same amount of protection.

Understanding the difference is the single highest-value hour a family earner can spend on their finances. Get it right and a household is protected for the price of a streaming subscription. Get it wrong and you either leave your family exposed or pour money into a policy that quietly underperforms almost every alternative.

What term life actually is

Term life is pure protection with an expiry date. You pay a modest premium; if you die during the term — say 20 or 30 years — your beneficiaries receive a fixed, tax-free lump sum. If you outlive the term, the policy ends and nobody gets a payout. That "nothing back" ending is not a flaw; it is precisely why term is cheap. The insurer is only ever on the hook for the risk itself, not an investment account.

Because there is no savings component, a healthy person in their thirties can often buy a large amount of cover for a strikingly small monthly premium. The job of term insurance is to bridge the years when other people depend on your income — while the mortgage is large and the children are young — and to disappear once those responsibilities are behind you and your own assets have grown.

What whole life adds — and charges for

Whole life (and its cousins, universal and endowment policies) never expires and bundles a savings or investment account, the "cash value", alongside the death benefit. That permanence and the built-in account are why the premiums are many times higher than term for the same cover. Salespeople emphasise that the cash value grows and can be borrowed against; what they emphasise less is how much of your early premiums are consumed by fees and commission before the account meaningfully grows.

For the vast majority of families, the honest verdict is "buy term and invest the difference": take the large premium gap between whole and term, and direct it into a low-cost investment account you control. The narrow cases where whole life genuinely fits are specific — certain estate-planning needs, a lifelong dependent with a disability, or business-succession arrangements — and they are the exception, not the default.

How much cover, for how long

A common rule of thumb is 10 to 15 times your annual income, plus any large debts (especially the mortgage) and major future costs such as children's education. The point is to replace the income your family loses and clear the obligations that would otherwise crush them. Set the term to cover the years of dependence — often until the mortgage is gone and the youngest child is financially independent.

Whatever you choose, answer every medical question on the application truthfully. Concealed information is the leading reason claims are rejected, and a rejected claim at the worst possible moment defeats the entire purpose of insurance. The cheapest policy is worthless if it does not pay out.
