How Much Life Insurance Do You Need? A Simple Way to Estimate – feature image
Educational, not advice. This article uses simple models and illustrative numbers. It is not financial, tax, insurance or medical advice. Rules and prices vary; check your own situation.
Key takeaways
  • Estimate the need from your own numbers, not just a multiple of income.
  • Include debts, mortgage, education and final expenses.
  • Subtract savings and existing cover to find the gap.
  • Review after big life events.

Life insurance exists to replace what your family would lose if you died. A rule of thumb like “ten times your income” is a starting point, but it ignores your debts, your children’s future costs and what you already have. A needs-based estimate is more personal, and it is easy to do with our <a href="/tools/life-insurance-calculator">life insurance needs calculator</a>.

The needs-based method

Add up what the family would need, then subtract what is already covered:

  • Income to replace for a number of years (until the youngest child is independent, for example).
  • Debts other than the mortgage.
  • Mortgage balance.
  • Education costs for children.
  • Final expenses.

Then subtract savings and investments, and existing life insurance (including any through work).

A worked example

Annual income $60,000 replaced for 10 years is $600,000. Add $15,000 of other debts, a $200,000 mortgage, $80,000 for education and $15,000 of final expenses: the total need is $910,000. With $50,000 of savings and $100,000 of existing cover, the gap is $760,000. That is the amount to discuss with a licensed adviser, not a decision by itself.

What the estimate leaves out

  • Inflation and investment returns on the payout.
  • A surviving partner’s income and any benefits.
  • Employer cover that ends if you change jobs.
  • Special needs, such as long-term care for a dependant.

Do stay-at-home parents need cover?

Often yes, because childcare, cooking and household management would need to be paid for. Include an estimate of that cost as the “income” to replace.

Types of cover

Term insurance covers a set period, such as 20 years, and is usually simpler and cheaper. Permanent (whole or universal) insurance lasts for life and includes a savings component with higher premiums. Which fits depends on your goals and budget, so compare quotes from more than one insurer.

When to review

Revisit the number after marriage, a new child, a home purchase, a large new debt, a change in income or when debts are paid off. As the mortgage and children’s costs shrink, your need often does too.

A note of caution

This article is educational and is not insurance or financial advice. Talk to a licensed professional about policy types, health underwriting and pricing.

Frequently asked questions

What is a good rule of thumb?

Some advisers suggest several times your annual income, but a needs-based estimate is usually more accurate for your circumstances.

Does work-based insurance count?

Yes, but it may end if you leave the job. Consider whether you need personal cover.

How long should the cover last?

Often until debts are paid off and children are independent.

How do I compare quotes?

Compare the same amount and term from more than one insurer, and check the insurer’s financial strength.
