Life Expectancy Calculator (2026): How Long Will You Need Life Insurance?
Most life insurance calculators tell you how much coverage to buy. Almost none tell you how long to buy it for, or how likely it is that the policy ever pays a claim. This life expectancy calculator answers both questions using the official Social Security Administration 2023 period life table, the same mortality data that underpins the 2026 Trustees Report and that carriers use as the starting point for underwriting.
Enter your age, sex, tobacco status and health class. The calculator estimates your life expectancy, prices the monthly premium for your coverage, then measures your term against your real obligation window: the years until your youngest child is independent, the years your spouse would need your income, and the mortgage you want retired. You will see the honest probability that a term policy pays a death claim, and the honest probability that you simply outlive it.
Life Expectancy & Coverage Horizon Calculator
Built on the SSA 2023 period life table (2026 Trustees Report). Estimates are illustrative and not an underwriting decision.
| Years from now | Your age | Chance still alive | Cumulative chance a claim was paid | Premiums paid |
|---|---|---|---|---|
| 5 | 50 | 97.9% | 2.1% | $13,800 |
| 10 | 55 | 95.0% | 5.0% | $27,600 |
| 15 | 60 | 90.8% | 9.2% | $41,400 |
| 20 | 65 | 84.9% | 15.1% | $55,200 |
| 25 | 70 | 77.2% | 22.8% | $55,200 term expired |
| 30 | 75 | 67.4% | 32.6% | $55,200 term expired |
How the numbers are built: the tool applies the SSA 2023 period life table for your sex, then scales the annual mortality hazard by your underwriting class (excellent 0.75, good 1.00, average 1.35, below average 1.75) and by 2.0 if you use tobacco. Life expectancy is the sum of the adjusted survival curve, which reproduces the published SSA life expectancy column exactly. Premiums use the site’s standard term rate matrix for a level term plan and are not quotes.
How This Life Expectancy Calculator Works
Life expectancy is not a guess. It is a calculation performed on a mortality table, and the Social Security Administration publishes the one that sets the baseline for the entire United States life insurance market. The table lists, for every exact age, the probability that a person dies within the next year. Chain those probabilities together and you get a survival curve. Add up the area under that curve and you get life expectancy.
This calculator does something a generic longevity quiz cannot. It rebuilds the survival curve from the SSA 2023 period life table separately for men and women, then lets you bend it to your own risk profile. Excellent health shrinks the annual mortality hazard to 75% of the population average. Tobacco use doubles it. Everything in between is modeled as a straight scaling of the hazard rate, which is the same proportional-hazards approach underwriters use when they build rate classes.
Two outputs matter most. The first is your obligation window, the number of years your family would actually need your income. The second is the claim probability, the chance that a term policy of the length you picked pays out before it expires. Those two numbers, placed side by side, decide whether your term is correctly sized.
Life Expectancy by Age: What the SSA Table Says
The table below comes directly from the SSA 2023 period life table, the mortality basis for the 2026 Trustees Report. It shows remaining years of life at each exact age. Notice how the numbers behave. A 30-year-old man can expect 47.5 more years; a 45-year-old man expects 34.2. The decline is slow through the forties and accelerates sharply after 60, which is exactly why term insurance premiums rise faster in the last two decades of a 30-year contract than in the first two.
| Exact age | Male life expectancy (years remaining) | Female life expectancy (years remaining) |
|---|---|---|
| 30 | 47.50 | 52.08 |
| 35 | 43.02 | 47.34 |
| 40 | 38.59 | 42.64 |
| 45 | 34.21 | 38.01 |
| 50 | 29.90 | 33.45 |
| 55 | 25.73 | 29.01 |
| 60 | 21.79 | 24.73 |
| 65 | 18.12 | 20.66 |
| 70 | 14.66 | 16.76 |

What Are the Odds Your Term Policy Actually Pays?
Here is the number nobody puts on a sales page: the probability that a term policy pays a death claim. It is not small, but it is nowhere near certain, and it is the honest yardstick for how much protection a premium dollar buys.
A 35-year-old man with average health has about a 7.9% chance of dying during a 20-year term. A 45-year-old man faces 15.1%. Stretch the same 45-year-old to a 30-year term and the claim probability roughly doubles to 32.6%, because the policy now runs through ages 45 to 75, where mortality compounds quickly. Women face materially lower mortality at every age, so the identical term carries a smaller claim probability, which is why female rates sit below male rates in every carrier's table.
| Age at issue | Chance a 20-year term pays a claim (male) | Chance a 20-year term pays a claim (female) |
|---|---|---|
| 30 | 6.2% | 3.3% |
| 35 | 7.9% | 4.5% |
| 40 | 10.8% | 6.4% |
| 45 | 15.1% | 9.4% |
| 50 | 21.1% | 13.5% |
| 55 | 29.0% | 19.6% |
| 60 | 39.9% | 29.1% |
Term length changes the answer as much as age does. For a man in average health, the claim probability across terms looks like this:
| Age at issue (male) | 10-year term | 20-year term | 30-year term |
|---|---|---|---|
| 35 | 3.1% | 7.9% | 17.7% |
| 45 | 5.0% | 15.1% | 32.6% |
| 55 | 10.6% | 29.0% | 59.8% |
Why "I'll Probably Outlive My Term" Is the Wrong Question
Most people who look at these numbers notice the same thing: in every row, the chance of outliving the policy is larger than the chance of claiming on it. That observation is true and it is also irrelevant to whether you should own coverage.
Insurance is not a bet you are trying to win. It is a transfer of a loss you cannot absorb. If the 84.9% outcome happens, you have paid premiums for two decades and received nothing, and your family never needed the money because you were alive. That is a good outcome, not a failed investment. The alternative framing, in which a policy is judged solely on whether it pays, quietly assumes your family could absorb the loss without it. For a household with a mortgage and dependent children, they could not.
The same logic explains why the claim probability rises steeply with term length. A 30-year term is not "better value" because it is more likely to pay. It is a different product covering a longer slice of life, and it costs more for exactly that reason. The right question is not which policy pays most often, but which term matches the years your family is actually exposed.

How Long Your Coverage Needs to Last
Your obligation window is the longest period during which your death would create a financial crisis. It has three common components: the years until your youngest child is financially independent, the years your spouse would need your income to maintain the household, and the remaining balance on a mortgage you want retired rather than inherited.
| Youngest child | Years until age 18 | Term length that covers it |
|---|---|---|
| Newborn | 18 | 20-year term |
| Age 3 | 15 | 15 or 20-year term |
| Age 6 | 12 | 15-year term |
| Age 10 | 8 | 10 or 15-year term |
| Age 14 | 4 | 10-year term |
| No children | 0 | Match to your spouse's income-replacement years |
If a child is your only obligation, a term that ends the year they turn 18 is enough. If your spouse is younger, earns less, or would lose retirement savings, their income-replacement years extend the window well past your children's independence. Coverage should end when the last of these exposures closes, not before.
Choosing a Term That Matches Your Obligations
- Write down your youngest dependent's age and count the years until they reach independence. That is your floor, not your ceiling.
- Estimate your spouse's income-replacement years. Twenty years is typical when a spouse is in their forties and would need support to retirement.
- Add mortgage years only if you want the loan retired outright rather than paid from the death benefit over time.
- Take the longest number and round up to the nearest available term, 10, 15, 20, 25 or 30 years.
- Check the price curve before stretching. Going from 20 to 30 years often costs 30% more per month; laddering a second smaller policy that starts later is frequently cheaper.
Smoking, Health Classes, and Life Expectancy Adjustments
Tobacco is the single largest lifestyle adjustment in both mortality and pricing. Public health research consistently places smoking-related mortality at roughly double the non-smoker rate, a hazard ratio that costs about a decade of life expectancy. The calculator applies a 2.0 hazard multiplier for tobacco, which moves a 45-year-old man's estimated life expectancy from 34.2 remaining years to about 27.2.
Insurers go further than the mortality gap alone. Carriers commonly price tobacco at about 2.8 times a non-smoker rate, because they also cover the years of chronic disease, higher treatment costs and the elevated mortality in the decade after diagnosis. That gap between a 2.0 mortality effect and a 2.8 price effect is not a trick; it is underwriting margin against uncertainty.
Health class works the same way. An excellent rating scales the population hazard down to 75%, roughly the mortality of someone a few years younger. A substandard rating scales it up to 175%. Those adjustments are the reason two people of the same age can be quoted premiums that differ by more than double, and why a medical exam or a review of prescription history matters more than the headline rate table.
Estimated Term Premiums by Age
The premiums below come from the same rate matrix the calculator uses, for a $500,000 level term policy over 20 years in the Good (preferred) health class. They are illustrative and designed to show the shape of the curve rather than to quote a specific carrier.
| Age at issue | Male, $500,000 / 20-year | Female, $500,000 / 20-year |
|---|---|---|
| 30 | $105 | $85 |
| 35 | $120 | $95 |
| 40 | $160 | $130 |
| 45 | $230 | $185 |
| 50 | $335 | $260 |
| 55 | $505 | $380 |
Compare those figures with the claim probabilities in the earlier table. A 45-year-old man paying $230 a month for 20 years commits $55,200 of premium against a $500,000 death benefit and a 15.1% chance the policy pays. That trade is the entire case for term insurance: a certain, affordable cost against a low-probability, catastrophic one.
Frequently Asked Questions
How long do I need life insurance?
Cover your obligation window, not your whole life. Add up the years until your youngest child turns 18, the years your spouse would need your income, and any mortgage you want retired. The longest of those numbers is your obligation window. A term policy that runs at least that long keeps coverage in force exactly as long as somebody depends on your paycheck.
What is the chance my term life insurance policy pays a claim?
It depends on your age and the length of the term. Using the SSA 2023 period life table, a 35-year-old man has roughly a 7.9% chance of dying during a 20-year term and a 45-year-old man about 15.1%. Over a 30-year term those figures rise to 17.7% and 32.6%. Women face materially lower mortality at every age, so the same term carries a smaller claim probability.
Does life expectancy affect my life insurance rates?
Yes. Carriers build their underwriting classes from the same mortality tables actuaries use to publish life expectancy, then add margin, expenses and commission. That is why tobacco use, a body mass index outside the build chart, or a chronic condition moves you into a more expensive class even when your personal life expectancy feels normal.
Is it a waste of money to outlive my term policy?
No. Term insurance is a bet on a low-probability, high-consequence event, and the most likely outcome is that you never file a claim. If your 20-year term expires unused you bought 20 years of protection for a family that would have lost your income, and you were alive to see your children grow up. That outcome is the point of insurance, not a failure of it.
How much does smoking shorten life expectancy and raise premiums?
Public health research puts smoking-related mortality at roughly double the non-smoker rate, which costs about ten years of life expectancy. Insurers price tobacco far more aggressively than the raw mortality gap, often at 2.8 times a non-smoker rate, because they also cover the years of chronic disease. Quitting restores preferred rates at most carriers after 12 to 24 months of documented tobacco-free time.
What term length should I choose if I have young children?
Match the term to the years until your youngest child finishes school. A newborn points to a 20 or 25-year term, a six-year-old to a 15-year term, and a teenager to a 10-year term. If a spouse would also lose retirement savings, stack a second longer policy instead of stretching one term past the point where the price climbs steeply.
Watch: How Much Life Insurance Do You Need?
Key Takeaways
- Life expectancy is a calculation on a mortality table, and the SSA 2023 period table is the baseline for the US market.
- Size the term, not just the amount: coverage should run until your last dependent obligation closes.
- A 45-year-old man in average health has about a 15.1% chance of dying during a 20-year term and 32.6% over 30 years.
- Outliving a term policy is the most likely outcome and still a good one; insurance transfers a loss you cannot absorb.
- Tobacco roughly doubles mortality but carriers price it nearer 2.8 times, and quitting can restore preferred rates in 12 to 24 months.
