How Much Life Insurance Do You Really Need?
7 min read
"How much life insurance do I need?" is usually answered with a rule of thumb - ten times your income, or a round million. Rules of thumb are a starting point, but they ignore the two things that matter most: the debts you would leave behind and the income your family would lose. A proper estimate takes five minutes and is far more accurate.
The DIME method
A widely used framework adds four numbers together:
- Debt. Mortgage balance, car loans, student loans and credit cards - everything that would need to be cleared.
- Income. The annual income you support, multiplied by the number of years your family would need it - often until the youngest child is independent.
- Mortgage. Some people list the mortgage separately and then size the income replacement on years rather than dollars.
- Education. The projected cost of schooling for each child, at today's prices.
Coverage ≈ debts + (income × years) + education + final expenses − existing savings
A worked example
Suppose you earn $60,000 a year, owe $220,000 on a mortgage and $15,000 in other debt, have one child and $30,000 in savings. Income replacement for 15 years is $900,000. Add debts ($235,000) and education ($60,000) and you get $1,195,000, minus savings leaves roughly $1,165,000. A 20-year term policy for that death benefit is often surprisingly affordable for a healthy applicant.
Term vs permanent for sizing
Most people need term insurance, because the need is temporary - it exists while children are dependent and the mortgage is outstanding. It buys the largest death benefit for the lowest premium. Permanent policies such as whole life cover you for life and build cash value, at several times the cost per dollar of coverage.
Do not forget the intangible costs
If a stay-at-home parent died, the family would have to pay for childcare, cleaning and transport that were previously free. That replacement value can easily exceed a salary and is routinely overlooked.
Frequently asked questions
Should I include my spouse's income? Yes, if the household relies on both incomes. Either death creates a gap that the survivor must fill.
Does coverage need to last forever? Rarely. Once the mortgage is paid and children are self-sufficient, the need usually drops sharply. Reassess at each major life stage.
