Example data table
| Scenario | Annual income | Replace | Years | Debts | Final | Education | Savings + investments | Existing coverage | Recommended |
|---|---|---|---|---|---|---|---|---|---|
| Sample household | $60,000 | 75% | 15 | $160,000 | $12,000 | $40,000 | $55,000 | $100,000 | $665,000 |
Formula used
PV = Payment × (1 − (1 + r)−n) ÷ r, where r is the real rate and n is years.
If r = 0, PV = Payment × n.
Total resources = existing coverage + savings + investments + accessible retirement + other resources.
Gap = max(0, needs − resources). Recommended = Gap × (1 + buffer%).

Coverage gap as a measurable number
This estimator converts your family’s obligations into one coverage target. It totals one‑time needs—final costs, debts, education, and emergency cash—then adds the present value of income support. From that figure it subtracts existing policies and liquid resources to show a gap. A 10% planning buffer and rounding help align results with common policy increments. Use it to compare scenarios when salary, debt balances, or savings change.
Income replacement using present value
Income replacement is modeled as an annuity, discounted to today’s value. You enter a replacement percentage, such as 75%, and the number of years support is needed. The calculator adjusts for other continuing income, like survivor benefits. It converts your nominal return and inflation assumptions into a real rate and applies PV = P × (1 − (1 + r)^−n) / r for predictable, level payments.
Debt, education, and final expense sizing
One‑time obligations often dominate early‑year risk. Paying off a 150,000 mortgage can eliminate monthly strain for survivors, while 10,000 in revolving debt avoids costly interest. Final expenses commonly range from 8,000 to 20,000 depending on location and services. Education goals vary widely; a 40,000 target can fund several years of tuition contributions. The emergency fund uses months × expenses unless overridden to match your cash reserve.
Resources and policy layering
Resources reduce the required coverage, but only if they are accessible. Existing life coverage from employers may be 1–2× salary and can change with job moves. Cash savings and brokerage assets usually count fully, while retirement funds may be partially available after taxes and penalties. This estimator lets you separate those buckets. If the gap is zero, you can still keep coverage for legacy goals too.
Practical ranges and review cadence
Results improve when assumptions are realistic. Many households choose a discount rate of 4%–6% and inflation near 2%–3%, but sensitivity testing is valuable. Try increasing replacement years to cover children until adulthood, then compare the new recommendation. Review the estimate annually, after major debt payments, or when savings jump. Use the CSV/PDF exports to document decisions and discuss options with advisors before you apply for coverage.
Frequently asked questions
What does “present value of income replacement” mean?
It estimates how much money today could fund future yearly support. The calculator discounts each year’s income need using the real rate, so your target reflects time value rather than simple income × years.
Should I include retirement accounts as resources?
Only include retirement amounts you expect survivors can access. Consider taxes, penalties, and account rules. If access is uncertain, enter a conservative portion or leave it out, then compare scenarios.
How do discount rate and inflation affect results?
Higher discount rates reduce the present value of future income needs, lowering recommended coverage. Higher inflation raises the real cost of future spending, which increases the present value unless offset by higher returns.
Why add a planning buffer?
A buffer helps cover uncertainty: investment returns, medical costs, timing gaps, and administrative expenses. Even small changes in assumptions can shift the gap, so a 5%–15% cushion can improve resilience.
How often should I update the estimate?
Update yearly, and after big changes like a new child, home purchase, job change, or major debt payoff. Refresh also when savings, coverage at work, or monthly expenses move materially.
Does a zero gap mean I need no coverage?
Not necessarily. A zero gap means current resources could cover listed needs. Many still maintain coverage for final expenses, legacy gifts, business continuity, or to protect against reduced savings during market downturns.
