Our free Life Insurance Calculator is designed to provide you with a personalized estimate of how much life insurance coverage your family should own. This tool helps you move beyond rough rules of thumb and understand the real numbers behind protecting your loved ones.
Simply enter your details below — including your life stage, income, debts, and future goals — and the calculator will show you an estimated coverage amount along with guidance on which type of policy may fit your situation best
This uses the Human Life Value method — it treats your future income as an asset, replaces it for the years your family would depend on it, and subtracts what you've already built. That's a truer number than any "10× your income" rule of thumb.
Income that keeps coming in for your family reduces what you need to replace. Leave at 0 for a single-income household.
Include employer or group life insurance here too — it's easy to forget, and it lowers what you need to buy.
This is the "Primary Insurance Amount" — the full monthly benefit at full retirement age, found on the ssa.gov statement. Leave at 0 or skip this section if unknown — an advisor can help.
We model this the way Social Security actually pays it: the caregiving parent's own benefit stops the month the youngest child turns 16, each child's own benefit continues separately to 18 (19 if still in high school — not modeled, treat as an approximation), the household total is capped at Social Security's family maximum, and if the surviving spouse works, their own benefit share may be reduced under Social Security's earnings test.
These are the levers a good advisor sets by hand. The defaults are sensible starting points — adjust them to match a real situation.
What the payout would earn once invested. The higher this is, the less you need today.
The income you're replacing rises with inflation — so the higher this is, the more you need, because your return has to outpace it.
Social Security caps a family's total survivor benefits, typically between 150%–188% of the worker's PIA depending on their earnings level. We default to the conservative low end so this doesn't overstate Social Security's help — raise it if you have the family's precise figure.
Your need shrinks as you age, debts shrink, and savings grow. Layering means you stop paying for coverage once you no longer need it — instead of one big policy you overpay for in later years.

Many people either buy too little coverage or pay for more than they need. A proper needs analysis helps you:

This tool evaluates several important elements that affect your life insurance needs, including:
The result is a more accurate picture than generic online calculators.
Term, whole life, universal life: They are all life insurance possibilities to discuss with your agent when you are ready to buy. Generally speaking, this tool is used as a term life insurance calculator, as we have included a possible way to consider layering your term life insurance coverage. This way, as your term-life insurance needs decrease over time, you aren’t overpaying and can allocate your resources efficiently.

Life insurance is highly personal. Our goal is to help you make an informed decision with clear information.
We have designed this life insurance calculator to give you a strong starting point for understanding the amount and types of life insurance coverage you should own. The methodology behind the calculator is known as "Human Life Value," which is an industry standard for income replacement. If you include Social Security survivor benefits, the calculator models the actual timing of those benefits — not a flat estimate — so the coverage gap reflects when Social Security's help changes, not just an average of what it pays. This tool provides an educational estimate based on your input, which should be finalized with a licensed life insurance agent who will consider your full financial picture, lifestyle, and future plans.
If you enter your family's information, the calculator models how these benefits actually change over time, rather than assuming one flat number. A caregiving parent's own benefit — sometimes called the mother's or father's benefit — runs only until the youngest child turns 16, even though each child's own benefit continues separately until 18 (19 if still in high school, which this tool doesn't account for). The household total is also capped at Social Security's family maximum, which can mean an additional child doesn't always increase what a family receives — the existing benefit is simply divided differently. If a surviving spouse continues working, Social Security's earnings test may also reduce their own share.
The calculator asks for your Primary Insurance Amount (PIA) — the full monthly benefit at full retirement age. You can find it by creating a free account at ssa.gov and viewing your Social Security statement. If you don't have it on hand, you can skip that section and refine the number later with an advisor.
Not necessarily. Because of the family maximum, a household already receiving the capped amount often sees little or no change when a new child is added — the total stays the same, just split differently. This surprises most families, since it's rarely explained this way. We walk through exactly how this works, and why it can hit smaller families harder than larger ones, in how the age-16 Social Security cliff actually works.
It depends on your goals, time horizon, and budget. Our calculator provides guidance based on your inputs, but many people start with term coverage for pure protection during their working years.
It’s a good idea to review your coverage every 3–5 years or after major life events (marriage, having children, buying a home, significant income changes, etc.). You can use this tool as a starting point but ultimately a licensed life insurance agent is your best resource for determining not only your life insurance requirements, but also your overall insurance portoflio.
