Life Insurance Coverage Needs Estimator
What this detailed household model adds: Use this estimator when a quick salary multiple is not enough. It calculates the annual household shortfall, converts that stream to present value, and keeps one-time obligations separate.
Build a detailed life insurance coverage gap using survivor income, replacement care, present value, debts, goals and resources already available.

Complete the detailed assumptions and press Calculate the household gap.
Run the model at zero and at a conservative positive rate. The result should not depend on one optimistic forecast.
How the annual gap becomes a current target
Income and replacement care are added, survivor income and benefits are subtracted, and the growing annual gap is converted to present value. Immediate obligations are added, resources are subtracted and the selected safety margin is applied last.
Model sequence
Annual household gap × growing present-value factor + immediate obligations - available resources + safety margin = modeled coverage gap.
Worked household cash-flow scenario
If income and replacement care total $78,000 and survivor income and benefits total $32,000, the annual gap is $46,000. The estimator converts that growing stream to present value before adding obligations, subtracting resources and applying the selected margin.
Is this the right calculator for a detailed estimate?
Use the detailed model when
Use this page when survivor earnings, paid replacement care and a return after inflation must be modeled as separate assumptions.
Use a simpler starting point when
It requires more judgment than a quick estimate. Use the basic calculator when you need an initial target before collecting detailed household figures.
Open the quick life insurance calculatorAssumptions worth stress-testing
- The selected return after inflation is an assumption, not a guaranteed policy return.
- Benefits, survivor earnings and care costs can change during the support period.
- Run lower and higher cases instead of relying on one precise result.
Questions about present value
Why does this estimator use present value?
Present value converts a stream of future household shortfalls into one amount today using the return after inflation that you enter.
What return after inflation should I use?
There is no universal rate. Test a conservative case, a middle case and a zero-return case so the decision does not depend on one forecast.
