What Is the DIME Method?
The DIME method is a systematic formula used by financial planners and insurance professionals to calculate how much life insurance a person needs. It is considered more accurate than simple rules of thumb because it accounts for your specific financial obligations rather than just your income.
DIME is an acronym for four components: Debt, Income, Mortgage, and Education. Each component adds up what your family would need if you were no longer there to provide for them.
Formula: (Debt + Income replacement + Mortgage + Education) − (Savings + Existing insurance + Spouse's income) = Recommended coverage
Breaking Down Each Component

D — Debt
This covers all outstanding debts that your family would need to repay, excluding the mortgage (which has its own category). Include:
- Car loans and personal loans
- Credit card balances
- Student loans (even if in your name)
- Any co-signed loans
- Business debts you have personally guaranteed
These debts do not disappear when you die. In most countries, they become claims against your estate — which means your family's inheritance shrinks to cover them, or worse, they inherit the obligation directly.
I — Income
This is typically the largest component. The question is: how many years of income does your family need to maintain their lifestyle after you are gone?
The DIME formula uses: annual income (or expenses) × number of years needed. Most advisors recommend 10–15 years, but you should consider your youngest child's age — you want coverage until all children are financially independent, typically around age 22–25.
M — Mortgage
The outstanding balance on your home loan. This is kept separate from other debts because it is usually the largest single obligation and has unique importance — your family's home is at stake.
If your family could not make mortgage payments after your death, they would eventually lose the home. Life insurance coverage equal to the mortgage balance ensures that does not happen.
E — Education
The estimated cost of higher education for each of your dependent children. Multiply your per-child estimate by the number of children.
Education costs vary enormously by country — from near-zero in some Nordic countries to $200,000+ for a US private university. Use a realistic estimate for your country and your aspirations for your children's education.
Worked Example
| Component | Description | Amount |
|---|
| D — Debt | Car loan + credit cards | $35,000 |
| I — Income | $55,000 expenses × 12 years | $660,000 |
| M — Mortgage | Remaining balance | $320,000 |
| E — Education | 2 children × $65,000 | $130,000 |
| + Funeral costs | Estimated final expenses | $15,000 |
| Total Needs | $1,160,000 |
| − Savings | Existing investments | –$50,000 |
| − Existing policy | Employer coverage | –$100,000 |
| − Spouse PV | Partner's income (discounted) | –$280,000 |
| Recommended Coverage | $730,000 |
Why DIME Is Better Than Rules of Thumb
Simple rules like "10× your salary" ignore critical factors. Consider two people both earning $80,000 per year:
- Person A — no children, no mortgage, $200,000 in savings. Needs perhaps $200,000–$300,000.
- Person B — three young children, $400,000 mortgage, minimal savings. Needs $1.2 million or more.
Both would get the same "10× rule" result of $800,000. Person A would be massively over-insured, paying unnecessarily high premiums. Person B would be dangerously under-insured, leaving their family exposed.
