Understanding life insurance needs estimate — two-scenario comparison
Everyday editorial team · GEOINNOVATION CO., LTD · Published · Updated
What this calculation is for
A life-insurance needs estimate organizes the obligations a household might face after losing an income. It combines income support with debts and care or education goals, then recognizes existing liquid resources and coverage.
How the method works
The model discounts end-of-year income support over the selected period, adds debts and other named goals, and subtracts liquid assets and existing cover. At a zero discount rate, income support is simply annual income times years; there is no artificial reduction.
A worked example
Replacing $50,000 for ten years requires $500,000 before discounting. A 0% discount assumption keeps that full amount. Debts and education goals increase the estimate, while available assets reduce the modeled gap.
Assumptions and real-world differences
Survivor benefits, future earnings, taxes, inflation, policy ownership and the timing of obligations can materially change needs. The result does not establish insurability, premiums or a recommended insurance product. Avoid subtracting assets that dependents cannot realistically access.
Building two independent scenarios
Scenario A and Scenario B each have a complete set of inputs for this life insurance needs estimate calculation. Change several inputs in B when comparing genuinely different plans, then inspect the B-minus-A headline difference and the detailed rows. When multiple inputs change, the total difference cannot be attributed to just one of them.

Frequently asked questions
- Does existing coverage include employer insurance?
- It may, but consider portability and whether the benefit would still be in force in the scenario.
- Is the gap a policy recommendation?
- No. It is a simplified planning estimate to discuss with a qualified adviser.
- Why is this different from the one-factor comparison?
- The one-factor tool changes only annual household income to replace. This version lets all model inputs differ, so it is more flexible but does not isolate the effect of any single change.
