Key takeaways
04 · ideas- DIME method adds Debt, Income replacement, Mortgage, and Education
- Human Life Value estimates the present value of future earnings
- The multiple-of-income approach is a simplified rule of thumb
- Different methods reflect different assumptions about what insurance should accomplish

Three main methods are used to estimate life insurance coverage needs.
1. DIME Method:- Debt: All non-mortgage debt
- Income: Annual income x years of replacement needed (typically 10-20)
- Mortgage: Outstanding balance
- Education: Projected college costs for children
2. Multiple of Income: 10-12x annual income. A rough rule of thumb for quick estimates.
3. Human Life Value: Estimates the present value of all future earnings, accounting for taxes and personal consumption.

DIME example
| Component | Amount |
|---|---|
| Debt (car + student + credit card) | $28,000 |
| Income ($80,000 x 15 years) | $1,200,000 |
| Mortgage balance | $310,000 |
| Education (2 children x $90,000) | $180,000 |
| Total (DIME) | $1,718,000 |
| Minus existing coverage | -$100,000 |
| Additional coverage needed | $1,618,000 |
Comparing methods
| Method | Result | Focus |
|---|---|---|
| DIME | $1,618,000 | Specific financial obligations |
| 12x income | $1,080,000 | Simple rule of thumb |
| Human Life Value | ~$700,000 | Income replacement only |
The DIME method generally produces higher figures than the others because it includes specific obligations like mortgage payoff and education funding. The method appropriate for a given situation depends on the specific financial goals involved.

Present value of income streams
The Human Life Value uses a present value calculation:
For an annual contribution of C = \49,000, discount rate r = 5\%, and n = 27$ years remaining to work:
The choice of discount rate significantly affects the result. Higher rates lower the present value; lower rates raise it.
