Build a transparent starting estimate from the obligations you choose, then compare it with resources and existing coverage.
A $60,000 annual income replaced for 10 years is $600,000 before adding debts and other needs. Subtract usable assets and existing coverage to see an estimated gap.
Your estimated gap appears after calculation.
How to estimate a life insurance coverage gap
List the income survivors would need each year and choose how many years that need may last. Add debts, final expenses, and education costs you want covered. Then subtract assets available to survivors and current life insurance benefits. The remaining positive amount is a planning gap, not an amount you must purchase.
Review what each existing policy actually pays, its exclusions, ownership, beneficiaries, and whether employer coverage is portable. An insurance professional can help account for policy terms and household circumstances.
Coverage gap formula and assumptions
The model multiplies annual income to replace by the years entered, adds three lump-sum needs, and subtracts usable assets and existing death benefits. It floors a negative gap at zero. It does not discount future cash flows, model inflation or taxes, estimate premiums, or decide whether term or permanent insurance is suitable.
Use consistent units: annual income, years, and one-time dollar amounts. A mortgage included in debts should not also be embedded in a separate lump-sum goal.
Worked example: replacing income for 10 years
Replacing $60,000 a year for 10 years gives $600,000. Add $150,000 in debts and $15,000 in final expenses for $765,000 in modeled needs. Subtract $25,000 in usable assets and $100,000 in existing coverage. The resulting gap is $640,000. This example does not imply that $640,000 is suitable for another household.
What this estimate can miss
Childcare and unpaid household work may create needs even if the insured person has little wage income. Existing employer coverage may end with employment. Savings may be reserved for retirement rather than survivor costs. Inflation, investment returns, benefits, taxes, policy exclusions, and changing debts can alter the result. Revisit the assumptions after major family or income changes.
Life Insurance Needs FAQs
Is this a quote or recommendation?
No. It is an arithmetic scenario based on your inputs, not a policy quote or personalized advice.
Should I include employer coverage?
Only if you understand its benefit amount and whether it remains available under the circumstances being modeled.
Why can the result be zero?
Entered assets and existing coverage can meet or exceed the modeled needs. That does not assess policy suitability.
Does it include inflation?
No. The income replacement amount is held constant for the chosen number of years.
