The most common way people pick a coverage amount is to multiply their salary by some number. The Insurance Information Institute cautions against exactly that, noting that many people end up underinsured because they take the shortcut instead of working through what their survivors would actually need.
The alternative is a needs analysis, and it is arithmetic rather than judgment.
The needs-based method
The structure is simple: add up what your survivors would need, subtract what they would already have, and the difference is the gap life insurance is there to fill.
The III groups the needs into three categories.
Final expenses. Funeral and burial or cremation costs, any outstanding medical bills, taxes, and the administrative costs of settling an estate. These arrive immediately and are the least flexible item on the list. Coverage aimed specifically at this need is covered in what is final expense insurance.
Debts. A mortgage balance, car loans, credit card balances, private student loans and any co-signed obligations. Not all debts survive you in the same way, and treatment depends on the type of debt and on state law, particularly in community property states. Ask a licensed professional about your own situation rather than assuming.
Income needs. The ongoing money your household needs after you are gone, for as many years as they need it. This is the largest and least obvious component.
Getting income needs right
Two things get missed most often.
Hidden income. Your paycheck is not the whole of what you contribute financially. The III uses the term for compensation that never appears in gross wages: an employer's share of health insurance premiums, retirement plan matching contributions and other benefits. Replacing health coverage alone can be a substantial ongoing cost for a surviving household.
Unpaid work. A household member who does not earn a wage still provides services with a real replacement cost. Childcare, eldercare and household management are all things survivors may need to pay for. This is why the question "does a stay-at-home parent need life insurance" has a straightforward answer: it depends on what replacing their contribution would cost.
Also plan for changes rather than only continuity. Survivors may relocate, a spouse may return to school or re-enter the workforce, and children's costs change as they grow.
Subtracting existing resources
Most households have post-death resources besides insurance, and counting them keeps you from buying more coverage than you need.
- Social Security survivor benefits, which the III describes as the most common resource. They are payable to a surviving spouse caring for dependent children; otherwise a surviving spouse generally waits until a later age, or an earlier one with a disability. Eligibility rules are specific and the Social Security Administration is the authority.
- Existing life insurance, including group coverage through an employer. Note that employer coverage usually ends with employment, so it is a resource with a condition attached. See group life through work vs an individual policy.
- Retirement accounts, savings and investments, adjusted for how accessible they are and how they are taxed on distribution.
- Pension survivor benefits, if any, and their election terms.
- Other household income that continues.
- Veterans benefits, where applicable.
The gap between total needs and total resources is your coverage target.
Why the income multiple shortcut fails
A multiple of salary ignores everything that makes households different: how many years of support are needed, what debts exist, what resources are already in place, and what the survivors' costs would actually be.
Two households with identical incomes can have very different answers. One with a paid-off home, adult children and a large retirement balance may need very little. One with a new mortgage, young children and no savings may need a great deal.
The shortcut is not useless as a sanity check on a number you arrived at some other way. It is a poor substitute for arriving at the number.
Deciding the term as well as the amount
Amount and duration are one decision, not two. A useful way to frame it: how many years would the money need to last?
- Until the youngest child finishes their education
- Until the mortgage is paid
- Until a spouse reaches an age where retirement resources become available
- For life, where the obligation is permanent, such as providing for a dependent with a lifelong disability or covering estate costs
The answer points at term or permanent coverage as much as at a dollar amount. See term vs permanent life insurance.
Some households use a layered approach: a longer-term policy for the obligations that persist, plus a shorter one covering the years of highest need, so coverage steps down as obligations do.
Revisit the number after life events
A coverage amount that was right once quietly stops being right. Reasons to recalculate:
- Marriage, divorce or remarriage
- A birth or adoption
- Buying a home or refinancing
- A significant change in income, for you or a spouse
- A child becoming financially independent
- Taking on or paying off major debt
- A business ownership change
- A dependent's long-term care needs becoming clear
Each of these also changes who should be receiving the money, which is a separate decision covered in naming a life insurance beneficiary.
Also revisit who owns the policy and whether the amount fits your estate plan. Depending on ownership and the size of the estate, proceeds may be included in the taxable estate even though they are generally not taxable income to the beneficiary. That is a question for an estate attorney or tax professional, not a general article.
Where to get help with the calculation
The inputs are personal: your household's expenses, your debts, your survivors' likely choices, and the resources already in place. A licensed agent can run a needs analysis with you, and a fee-only financial planner can do the same without a product attached. Social Security survivor benefit estimates come from the Social Security Administration.
Coverage availability, underwriting and pricing vary by insurer and by state, and the policy documents control. To get connected with licensed carriers and agents who write life insurance in your state, you can request life insurance quotes.
