Most households have never run this calculation. The question isn't how much life insurance you want — it's what happens to your spouse's monthly income and monthly expenses when one of you is gone. Those two numbers, subtracted from each other, produce the gap that life insurance is designed to fill.
The calculator below runs the Social Security survivor math and gives you a planning estimate specific to your situation. It is not a sales illustration. It is a planning tool.

The Survivor Income Drop — What Actually Changes
When one spouse dies, two things happen at once. Household income drops — sometimes significantly. Household expenses largely stay the same.
The Social Security survivor piece is the clearest example. Today your household may receive two checks. When one spouse dies, the survivor keeps only the higher of the two and loses the lower one permanently. If your household receives $2,200 and $1,400 per month, the $1,400 disappears on the day one spouse dies. That is a $16,800 per year income reduction before any other changes are counted.
Pension income may drop further. If a pension was elected as single-life only at retirement — which pays a higher monthly amount but stops at death — the surviving spouse loses that income stream entirely. That pension election, often made once and irrevocably at retirement, is one of the single biggest variables in how much life insurance a household actually needs.
The tax impact compounds the income drop. A surviving spouse files as a single taxpayer rather than married filing jointly. That raises effective tax rates, reduces the standard deduction, taxes a larger percentage of Social Security income, and can increase Medicare premiums through IRMAA. In practice, the income drop is usually larger in real terms than the raw numbers suggest.
The Debt and Obligation Layer
Beyond income replacement, life insurance addresses the financial obligations that survive the person. The mortgage is the most common: most Washington households with a mortgage have a surviving spouse who could not carry that payment alone on a reduced income. Life insurance provides the choice — pay off the mortgage entirely, or give the survivor financial flexibility to decide what serves them best.
Outstanding debts, car payments, and other obligations that assumed two incomes also warrant consideration. Life insurance does not have to cover every obligation, but knowing which ones create real vulnerability helps right-size the coverage rather than picking a round number.
The Employer Coverage Gap
Roughly 30 percent of workers rely primarily on employer-provided life insurance. That coverage typically ends when the job ends — frequently at exactly the moment a person is transitioning into retirement, when their health has changed and the underwriting window for private coverage may be narrowing.
Employer life insurance also rarely fills the full income gap. Group coverage is typically one to two times annual salary. For a household where one spouse's death would create a $2,000 per month income shortfall for 20 years, one to two times salary rarely covers the math.
What the Calculation Looks Like
The survivor income approach works like this:
- Identify what monthly income disappears. Social Security reduction plus any pension income that stops.
- Identify what monthly expenses remain. Mortgage or rent, utilities, insurance, food, transportation, healthcare.
- Calculate the monthly gap. Monthly expenses minus surviving income. If the result is positive, a gap exists.
- Size coverage to fill the gap for a meaningful period. A monthly gap of $1,500 for 20 years requires $360,000 of coverage to fill it completely — not accounting for investment returns on the death benefit.
This is a planning estimate, not a financial plan. It doesn't account for existing savings, investment accounts, other income sources, or how the death benefit might be invested. A 15-minute conversation with a licensed advisor can apply this framework to your actual numbers. You can also explore the rest of the life insurance section for the related planning topics.
