Formula Used
This tool estimates required coverage using a needs-based approach: income support (present value) plus one-time goals, then reduced by offsets.
Income Replacement Benchmarking
A practical starting point is replacing 60% to 80% of gross income for working years. For a $60,000 income and 70% target, year-one support is $42,000, or $3,500 monthly. This tool converts that target into a present-value funding need, so coverage reflects time value and not a simple income multiple.
Inflation and Horizon Sensitivity
Inflation grows the support stream, while the return assumption discounts it. With 3% inflation and 5% return over 25 years, the present value of a $42,000 first-year need is lower than the nominal sum of payments. If inflation rises to 4% with the same return, required coverage typically increases because future cash flows grow faster.
Debt and Education Load Mapping
One-time obligations are added at face value to the plan. A mortgage balance of $80,000 plus final expenses of $10,000 immediately lifts the funding target by $90,000. If there are two dependents and a $20,000 education goal each, education adds $40,000 to the requirement, helping you quantify goals that are often underestimated. Adding a six-month buffer equals 6 × $3,500 = $21,000, supporting bills during transition. A separate $25,000 legacy goal can fund charitable gifts or milestones without reducing the income support plan for survivors and dependent care.
Asset Offsets and Coverage Layering
Offsets reduce the gap: existing policies and liquid assets are subtracted from total needs. For example, $50,000 existing coverage and $25,000 assets reduce the required new coverage by $75,000. This encourages layering, where employer coverage, term insurance, and savings each play a defined role.
Scenario Discipline and Review Cadence
The calculator runs conservative and optimistic return cases by shifting the return assumption by 2 percentage points. If the base return is 5%, scenarios evaluate 3% and 7% to stress the coverage gap. Recheck assumptions after major events—marriage, a new loan, a child, or a pay change—so coverage remains aligned with the household balance sheet.
