How Much Life Insurance Cover Does a Family Need?

Arjun has a policy and no idea whether it is enough

Arjun has life cover, taken out at some point because it seemed like the responsible thing, in an amount somebody suggested. He has a young child and a home loan a few years into its term.

If you asked him whether the cover was sufficient he would say he assumed so. He has never checked, and the reason is that checking sounds like it requires expertise it does not require. The calculation is subtraction, and the reason to do it rather than accept a rule of thumb is that rules of thumb cannot know about his loan, his child's age, or what his wife earns — which are precisely the things that determine the answer.

Why the salary multiple is not the answer

The common shortcut is some multiple of annual income. Its appeal is that it needs no work, and its problem is that income is not what has to be replaced.

Two people earning identically can need wildly different cover. One has a large outstanding loan, two young children and a spouse who does not earn. The other has no debt, no dependants and a spouse earning as much again. The first needs a great deal; the second may need very little. A multiple applied to both is not a calculation — it is a way of avoiding one.

The multiple is useful for exactly one thing: as a rough sanity check afterwards. If the proper calculation lands in a wildly different place, that is worth investigating. It is not the method.

What has to be replaced

The first half is the size of the hole. Five components, and the largest is usually the first.

The income the family loses, for as long as they would need it. Not Arjun's whole salary — the part of it that supports the household after removing what he himself consumes. And not forever: the period runs until the youngest child is independent, or until his wife's own income and the remaining assets would carry things. This is the component where a lump sum has to stand in for a stream, and it is why the sum is large.

Debts the family should not have to carry. The home loan is the obvious one. Whether it should be cleared entirely or serviced from the replaced income is a real choice — clearing it removes the instalment from every future month, which usually simplifies everything at a difficult time.

Goals that must survive. A child's education is the main one. This is a dated schedule of amounts rather than a single figure, and the method is the staged education estimate.

Immediate costs. Medical bills preceding a death, the funeral, and the practical costs of a family reorganising itself — which can include a move, or a period during which a surviving spouse cannot work.

Support given to others. Anything Arjun currently provides to parents or other dependants that would otherwise stop.

What to subtract

The second half is what the family would already have, and there are three traps in it.

Subtract assets genuinely available to survivors — investments, deposits, existing life cover from any source including an employer's, and any dependable income a surviving spouse would have.

Do not subtract the emergency reserve. It is already committed to its own job, and counting it here means it does two things at once, which it cannot. This is the same double-counting error that inflates every property-heavy plan.

Do not subtract the home the family lives in. They have to keep living somewhere, and a house that would have to be sold to release its value is not available to fund anything. It counts only if they would genuinely move to something smaller.

And be careful with employer cover. It ends when the employment does, which means it is exactly the cover that disappears in the scenarios where a household is already under strain. Counting it as permanent is a mistake covered in why employer insurance is not enough.

What remains after the subtraction is the cover needed. If it is negative, Arjun does not need life cover, which is a legitimate and under-reported outcome — a household with no dependants and no debt frequently does not.

The assumptions, and how to keep them honest

Two numbers enter the calculation that nobody knows, and both should be handled conservatively rather than optimistically.

Whatever return is assumed on the lump sum while the family draws on it should be modest. This money will be held by someone dealing with a bereavement, and it belongs somewhere stable; assuming an equity-like return means assuming a grieving household manages a volatile portfolio successfully at the worst moment of their lives.

And the spending being replaced rises with prices over the support period, so the sum has to account for that. This page carries no figure for either, because both are assumptions rather than sourced values, and the whole point of the exercise is that Arjun uses his own. The measured range Indian inflation has actually run at is in choosing an inflation assumption, and it is wide.

Because both assumptions are uncertain, the sensible practice is to compute the answer twice — once optimistically, once conservatively — and take the higher, since the cost of over-insuring is a somewhat larger premium and the cost of under-insuring falls on people who cannot do anything about it.

The amount is only half of it

A correct sum insured on a policy that does not pay is worth nothing, so the structure deserves as much attention as the number.

The term has to cover the period of need, which usually means until the youngest child is independent and the loan is repaid. Cover that expires before then leaves exactly the gap it was bought to fill.

The premium has to be affordable indefinitely. A policy lapsed in year seven because the premium became uncomfortable provided no protection at all. This is the strongest practical argument for buying protection as protection rather than bundled with an investment, which is dealt with in evaluating insurance-investment products.

The disclosures have to be complete and accurate. Non-disclosure is a leading reason claims are contested, and the moment of application is the only opportunity to get it right.

The nomination has to be current, and the family has to know the policy exists, which insurer holds it, and how to claim. A policy nobody can find is a policy that does not pay.

Recalculate it after anything changes

The requirement is not fixed. It rises with a marriage, a child, a new loan or a higher standard of living, and it falls as the loan amortises, as assets accumulate and as children become independent.

Most households are under-covered in their thirties and over-covered in their late fifties, and both are the same error: a number set once at a moment that has passed. The review is quick once the first calculation exists, because only the inputs that changed need revisiting.

What to take away

Add up the income your family would need replaced and for how long, the debts they should not carry, the goals that must survive, the immediate costs and any support you provide. Subtract what they would genuinely have — but not the emergency reserve, not the home they will keep living in, and not employer cover you might not still hold.

The difference is the cover you need, and it may be nil. Use conservative assumptions for return and inflation, and compute it twice. Then check the term covers the period of need, that the premium is affordable for the whole of it, that the disclosures are complete and the nomination current — and recalculate after anything in your life changes.
