How Much Life Insurance Do You Need? The DIME Method

Why rules of thumb fall short

"Ten times your salary" is easy to remember and better than nothing, but it treats everyone the same. A single renter with no dependants and a parent of three with a mortgage need wildly different amounts, yet the rule hands them the same multiplier. It ignores what the money is actually for: keeping a family financially whole if the income earner is gone.

The better approach starts from the obligations you would leave behind and the income your household would lose. That is what DIME does: it builds the number from four concrete buckets you can look up or estimate, rather than a single multiplier pulled from the air. The result is a figure you can explain and defend, and one you can update as your debts shrink and your children grow up.

Working through DIME step by step

Start with D for Debt: total everything except the mortgage — credit cards, car loans, student loans and any balance you co-signed. Then I for Income: decide how many years your family would need your income and multiply. Ten years of a $30,000 net contribution is $300,000. Some families extend this until the youngest child is independent, which lengthens the horizon.

M is the Mortgage: add the outstanding balance so the home is paid off and no one has to move under pressure. E is Education: estimate the cost of schooling or university for each child, adjusted for the kind of education you intend to fund. Add the four buckets, then subtract what you already have — savings, investments and any existing policy. A calculator keeps the running total straight and lets you test different year counts in seconds.

Term vs whole, and how to keep it right-sized

For most families, term life insurance covers the DIME need cheaply because it lasts exactly as long as your obligations do — the years while the mortgage runs and the children are dependent. Whole-life and permanent policies cost far more for the same death benefit because they bundle an investment component, which is rarely the most efficient way to invest. Match the term length to the year your biggest obligations end.

Revisit the number every few years or after any major life change — a new child, a bigger mortgage, a pay rise or paying off a loan. As debts fall and savings grow, your required cover usually drops, and you may be able to reduce premiums. Life insurance is not a set-and-forget purchase; it is a moving target that shrinks as your financial obligations do.

Frequently asked questions

Does everyone need life insurance?

No. Life insurance mainly protects people who financially depend on you. If no one relies on your income and you have no shared debts, you may need little or none. The need rises sharply once you have a partner, children or a mortgage.

Should I include my mortgage in the coverage?

Yes, if you want your family to keep the home without the monthly payment. The M in DIME is the outstanding mortgage balance. If you already hold separate mortgage-protection cover, count that as existing coverage and do not double up.

Is term or whole life better for the DIME need?

Term life is usually the efficient choice, because the DIME need is temporary — it fades as debts clear and children grow up. Term gives you a large death benefit for a low premium over exactly the years you need it. Whole life costs much more for the same benefit.

How often should I recalculate my coverage?

Review it every two or three years and after any big change: a new child, a house move, a large raise or clearing a debt. Coverage needs usually fall over time, so recalculating can let you reduce cover and premiums rather than overpay.
