Model Two Scenarios: What Happens if Each Spouse Dies?
Step 1: Model Spouse A’s death. Step 2: Model Spouse B’s death separately. The needs are often asymmetric: the higher earner may need more income replacement but the surviving lower-earning spouse may have adequate income for some expenses. Don’t average or combine the calculation — each spouse’s death creates a different financial scenario.
Sample Calculation: Dual-Income Family
Dual-income family life insurance calculation: two separate scenarios
| Scenario | Spouse A dies ($95K earner) | Spouse B dies ($60K earner) |
|---|---|---|
| Income loss | $95,000/year | $60,000/year |
| Surviving income | $60,000/year (Spouse B) | $95,000/year (Spouse A) |
| Income gap (20 yrs) | $35,000 × 20 = $700,000 | $0 gap (Spouse A can cover) |
| Add: mortgage | +$280,000 | +$280,000 (still shared) |
| Add: education | +$200,000 | +$200,000 |
| Less: existing savings | -$80,000 | -$80,000 |
| Net coverage need | ~$1,100,000 | ~$400,000 |
Even if both spouses earn similar incomes ($80K and $70K), each still needs coverage. The loss of either income would not be fully absorbed by the survivor — mortgage payment, childcare, and lifestyle costs assume both incomes. Both spouses should carry coverage proportional to their individual income contribution to shared expenses.
Childcare Costs in Dual-Income Coverage Calculations
When both parents work, childcare arrangements may depend on both incomes. If Spouse A dies and Spouse B’s income alone can’t support existing childcare costs plus reduced household income, additional coverage need exists. Factor in the cost of childcare changes the surviving spouse might need to make: can they continue working? Do they need more childcare (working longer hours to compensate)? Less childcare (reducing hours)?
Model Each Spouse’s Coverage Need Separately
Run the calculation for each spouse independently to find the right coverage for each scenario.
