Estimating coverage with the DIME method

Life insurance exists to replace what your income would have provided. DIME breaks that into four measurable pieces — Debt, Income, Mortgage, Education — which turns a difficult emotional question into an arithmetic one.

Why income replacement dominates

At $600,000, income replacement is 70% of the total. The number of years you choose therefore matters more than any other input — dropping from 10 years to 5 lowers the total need to about $545,000, a $300,000 swing.

The right figure depends on what you're trying to fund. Until children are independent is one common anchor; until a surviving partner could return to full earning capacity is another. Longer isn't automatically better — it's a trade against the premium you'll pay for decades.

What each piece is doing

• Debt clears obligations that would otherwise fall to your family — car loans, credit cards, personal loans, and final expenses.
• Income replaces the earnings your household depends on.
• Mortgage is separated out because paying off the home eliminates the largest recurring cost and provides housing security.
• Education covers what you intended to fund for children.

Note a possible double-count: if your income replacement years were meant to cover mortgage payments too, counting both the full mortgage balance and ten years of income overlaps somewhat. DIME is deliberately conservative here, which is defensible — but worth knowing if the resulting number feels high.

What DIME leaves out

The method omits things that can matter significantly. A stay-at-home parent provides childcare and household work with real replacement cost, often substantial, despite no salary to replace. Ongoing costs like childcare, healthcare premiums that were employer-provided, and general living expenses beyond the mortgage aren't captured either.

On the other side, DIME ignores resources that reduce the need: a surviving partner's income and earning capacity, Social Security survivor benefits for eligible children, and existing retirement savings. This is why the result is a starting estimate rather than a precise figure.

Term versus permanent coverage

Term life covers a fixed period — commonly 10, 20, or 30 years — and pays only if you die within it. It's substantially cheaper, which is why large coverage amounts are usually affordable through term.

Permanent policies (whole or universal life) last for life and accumulate cash value, at considerably higher cost for the same death benefit.

The common guidance is matching the term to the need: coverage until the mortgage is retired and children are independent, after which the need largely disappears. That's precisely the window DIME measures. Permanent coverage tends to fit narrower situations — certain estate planning needs or dependents requiring lifelong support.

If your existing coverage already exceeds the need

Employer-provided life insurance is worth checking, though it typically covers only one to two times salary and usually ends when the job does — which makes it a supplement rather than a plan. If the calculator shows you're already covered, it's still worth revisiting after major changes: a new mortgage, another child, a significant income change, or a divorce.

What this calculator doesn't include

It's a rule-of-thumb estimate, not an underwriting assessment. It doesn't account for a surviving partner's income, Social Security survivor benefits, inflation over the replacement period, taxes, the value of unpaid household labor, or investment growth on a lump-sum payout — which could extend how long the money lasts.

Other methods exist, including human life value and detailed needs analysis, and they can produce meaningfully different figures. A licensed insurance professional can run a full analysis; this is a way to arrive at that conversation with a number in mind.
