How much life insurance do new parents need? A real-numbers breakdown

"10 times your salary" is the shorthand that gets passed around most often. It's not useless, but for new parents it misses too much of the picture. It doesn't account for your mortgage, your partner's earning potential, your childcare costs, or how long your children will actually be dependent on you.

This guide works through the calculation properly. The goal is a number you can actually use — not a vague multiplier, but a figure grounded in your family's specific financial exposure.

Start with what you're actually trying to cover

The purpose of life insurance is to ensure that if you die, the people who depend on you don't face financial ruin. That means the right amount covers:

• Your outstanding mortgage or rent liability
• The income your family would lose
• The childcare costs your partner would face without you
• Any other debts or financial obligations

These aren't theoretical — they're the actual costs your family would face within weeks of your death. Work through each one.

Component 1: The mortgage

If you have a repayment mortgage, the outstanding balance is the clearest number to start with. Your family needs somewhere to live; the immediate priority is ensuring they don't lose the house.

For a $280,000 outstanding balance, you need at least $280,000 of cover for this component alone. Some families opt for decreasing term cover specifically for the mortgage — the payout reduces in line with the balance — and a separate level term policy to cover everything else. Others prefer a single level term policy set high enough to cover both.

If you own jointly and have a joint mortgage, discuss whether each partner's policy needs to cover the full balance or just their share. An licensed insurance advisor will help you structure this correctly — it's a common point of confusion.

Component 2: Income replacement

How much of your take-home income would your family need to replace, and for how long? The standard approach is to estimate annual income replacement and multiply by the number of years your dependants will need it.

The simplest method: take your annual after-tax income and multiply by the number of years until your youngest child turns 18. That gives you a conservative income replacement figure.

Worked example:

• Annual take-home income: $42,000
• Child's current age: 1 year old
• Years to child's 18th birthday: 17 years
• Raw income replacement figure: $714,000
• Adjusted for investment return on lump sum (~4% discount): ~$510,000

The discount accounts for the fact that a large lump sum invested conservatively will generate returns over time — so you don't need the full undiscounted total. A rough shorthand is to take about 70–75% of the raw figure for a 15–20 year period.

For dual-income families, think about what income would be lost in the worst case — not what the surviving partner earns, but what they could sustain if also managing childcare alone. It's common for the survivor to reduce hours or pause their career in the first few years after bereavement.

Component 3: Childcare costs

This is the component most financial calculators omit, and for new parents it's the most consequential.

Full-time nursery for a child under 2 in the US currently averages around $14,000–$22,000 per year depending on region, with London at the upper end. If you have one child and your partner would need full-time childcare to continue working, that's a significant recurring annual cost for several years.

Childcare cost estimate — one child, aged 1:

• Full-time nursery (age 1–4), 3 years at $16,000/yr: $48,000
• Wraparound school care (age 4–11), 7 years at $4,000/yr: $28,000
• Total childcare provision estimate: $76,000

These are rough figures. Your actual costs depend heavily on where you live, whether you use the government's funded hours entitlement, and your working pattern. But as an order of magnitude, $50,000–$100,000 for childcare costs is realistic for a child under 2 today.

Putting the numbers together

Here are three worked examples for different household structures.

What these numbers cost in practice

These figures sound large, but the cost of the cover is not proportional to the sum assured in the way most people expect. Life insurance is actuarially priced — the insurer is covering an unlikely event, so the premiums are relatively modest for healthy adults in their 30s.

Indicative monthly premiums for a healthy, non-smoking 32-year-old:

• $300,000 level term, 20 years: approximately $8–$16/month
• $500,000 level term, 20 years: approximately $12–$24/month
• $750,000 level term, 20 years: approximately $18–$35/month

The range reflects differences in health, smoking status, family medical history, and insurer. Going from $300k to $600k of cover typically adds less than $300k-worth of proportional cost — the relationship is sub-linear.

Should both partners be covered?

Yes — even the partner who earns less, or who has taken time out of work. The domestic labour a stay-at-home parent provides has a real replacement cost: nursery, wraparound care, school runs, meal prep, household management. The cost of replacing all of that in the event of their death falls on the surviving working partner — often forcing them to reduce their hours or stop working entirely.

A separate policy for each partner is usually better value than a joint life policy, which pays out once (on the first death) and then terminates. Two individual policies mean two potential payouts.

How long should the term be?

The term should cover the period of financial dependency — usually until your youngest child reaches 18 or 21, or until your mortgage is repaid, whichever is longer. A 25-year term for a new parent in their early 30s is a common starting point.

You can increase cover later if circumstances change (new mortgage, second child), particularly if you include a Guaranteed Insurability Option in your policy — this allows you to increase your sum assured without new medical underwriting at specified life events.

One more thing: write your policy in trust

When you take out a policy, consider writing it in trust. This is free with most insurers, takes about 20 minutes, and means the payout goes directly to your chosen beneficiaries without going through your estate. Without a trust, the money can be held up in probate for months while your family waits. With one, it typically pays out within weeks.
