Free longevity risk calculator. Estimate survival probabilities by age using SSA actuarial tables, then see portfolio survival rates at each longevity milestone.
The Longevity Risk Calculator estimates your probability of living to various ages based on Social Security Administration actuarial life tables, then shows how those probabilities interact with your portfolio's sustainability. Longevity risk — the danger of outliving your savings — is the biggest financial threat retirees face.
A 65-year-old man has roughly a 35% chance of reaching 90 and a 15% chance of reaching 95. For women, those odds are even higher. Joint survival probability for couples is higher still. This calculator helps you understand what "planning to age X" really means in terms of probability.
By combining longevity probabilities with portfolio depletion modeling, you can see the true risk profile of your retirement plan. If your portfolio is projected to last 25 years but you have a 40% chance of living 30 years, the mismatch becomes obvious — and actionable. This calculator transforms abstract probabilities into concrete planning scenarios so you can decide whether to save more, spend less, annuitize a portion of your assets, or accept the calculated risk.
Most people underestimate their life expectancy. The average is just an average — half of retirees will live longer. Planning only to the average leaves a 50% chance of running out of money. This calculator shows the probability spectrum so you can decide how much risk to accept. It turns an abstract statistical concept into a practical planning tool tied directly to your money.
Survival Probability = Product of (1 - mortality rate) for each year from current age to target age Mortality rates from SSA Period Life Tables Portfolio Duration: years until balance = 0 given starting balance, withdrawal rate, and return Joint Survival = 1 - (1 - P_male) × (1 - P_female)
Result: Probability of reaching: 80: 70%, 85: 53%, 90: 35%, 95: 15%, 100: 4%
A 65-year-old male has approximately a 70% chance of living to 80, 53% to 85, 35% to 90, 15% to 95, and 4% to 100. If your portfolio only lasts to age 87, there's about a 45% chance you'll outlive it.
Longer life is a blessing but creates a financial challenge: the longer you live, the more money you need, but the money you have must last longer too. A retiree who lives to 95 needs 50% more savings than one who lives to 85, but most planning tools use a single life expectancy number.
Rather than planning to a single age, probability-based planning considers the full spectrum. A 10% survival probability at age 97 means 1 in 10 retirees will still be alive then. Whether to plan for that depends on your risk tolerance and resources. A secure baseline (Social Security + annuity) covering essential expenses, plus a portfolio for discretionary spending, is a robust strategy.
Joint planning is especially important. Even if each partner expects to live to about 85, the probability that at least one lives to 92 is quite high. The surviving spouse often faces higher per-person costs (loss of one Social Security check, higher tax bracket as single filer). Always plan for the survivor scenario.
Longevity risk is the possibility of outliving your retirement savings. It's considered the single greatest financial risk in retirement because it interacts with every other risk: market downturns, inflation, healthcare costs, and spending decisions all become worse problems the longer you live.
SSA period life tables represent average mortality for the U.S. population. Individual life expectancy can vary significantly based on health, genetics, lifestyle, and socioeconomic factors. Healthier, wealthier individuals typically live longer than tables suggest. Consider adjusting upward if you're in good health.
Joint survival is the probability that at least one member of a couple is alive at a given age. It's always higher than individual survival. For a 65-year-old couple (male + female), the probability of at least one living to 90 is approximately 72%, even though individual probabilities are 35% and 45%.
Financial planners typically recommend planning to at least age 90-95. More conservative planning targets age 95-100. The right answer depends on your risk tolerance and available resources. Planning to age 95 covers roughly 85-90% of the population.
Key strategies: (1) Delay Social Security to age 70 for the highest guaranteed income; (2) Purchase a lifetime annuity with a portion of savings; (3) Maintain a conservative withdrawal rate in early retirement; (4) Keep a reserve fund for extended longevity; (5) Ensure adequate healthcare coverage. Combining several of these approaches creates a layered defense that protects you even if one strategy underperforms.
Historical trends show steady improvement in longevity, though gains slowed in recent years. Medical advances, improved nutrition, and reduced smoking have extended life expectancy significantly. A child born today has a reasonable chance of living past 100. For retirement planning, it's prudent to assume continued improvement.
