🇺🇸 US Life Expectancy & Retirement Fund Calculator:
401(k), RMDs & Social Security
The only comprehensive US retirement calculator combining SSA actuarial longevity, Medicare & long-term care cost projection, SECURE 2.0 RMD tax analysis, Social Security claiming optimization, and Monte Carlo sequence-of-returns stress testing — 100% free.
Personalized US Life Expectancy Estimator (SSA Actuarial Data)
Uses health and lifestyle factors to project your personalized longevity — then shows survival probability at each age milestone.
401(k) & IRA Retirement Fund Longevity Model
Enter your savings, withdrawal rate, and income sources to see exactly how many years your fund will last — with a year-by-year depletion table.
Medicare & Long-Term Care (LTC) Cost Projector
Healthcare costs inflate at 7–9%/yr — far faster than general CPI. This module projects your total lifetime healthcare burden including Long-Term Care probability and costs.
Retirement Spending Phases (Go-Go, Slow-Go, No-Go)
Retirement spending is NOT linear. Research confirms three distinct phases: active early years (high spending), moderate middle years, and lower-but-healthcare-heavy late years.
IRS Required Minimum Distribution (RMD) & Tax Analyzer
IRS requires Required Minimum Distributions from 401(k)/Traditional IRA starting at age 73. This module shows the real after-tax fund longevity.
| Age | Balance | RMD Required | Tax on RMD | After-Tax Net |
|---|
Social Security (SSA) Claiming Age & COLA Optimizer
Claiming SS at 62 vs. 67 vs. 70 changes your monthly benefit by up to 76%. This module calculates the break-even age for each strategy.
Sequence of Returns Risk & Estate Legacy Planner
Test your retirement plan against pessimistic, base, and optimistic market conditions — including sequence-of-returns risk. Set a legacy goal and see what withdrawal rate preserves vs. depletes your estate.
A Comprehensive US Retirement
Planning Methodology
Most retirement calculators answer one question. This tool answers all seven — from how long you’ll live to exactly how much healthcare will cost, what taxes will take, and how sequence-of-returns risk could derail your plan. Start at Step 1 and follow the flow.
Generic life expectancy tables (US average: male 76.3, female 81.5) treat everyone the same. This module adjusts for BMI, smoking, physical activity, five chronic conditions, and family longevity history. The result: a personalized estimate that can swing ±10 years from the population average — and a Gompertz survival curve showing probability of being alive at every age from today to 110.
The core question every retiree asks: “Will I outlive my money?” Enter your savings, monthly expenses, Social Security income, pension, investment return, and inflation rate. The module runs a year-by-year simulation showing when — and if — your fund reaches zero. You get a depletion age, a fund runway chart, and a full table of annual balances.
Healthcare costs inflate at 7–9% per year — more than twice the general CPI rate. Most retirement calculators ignore this. Module 3 models your annual healthcare costs from retirement through your planning age using true medical inflation, adds long-term care probability (70% of Americans will need it), and calculates your grand total lifetime burden. This is the number that most often shocks users — and most often goes unplanned.
Retirement spending is not a flat line — yet almost every calculator models it that way. Research by David Blanchett (Morningstar) confirms a predictable three-phase pattern: a high-activity Go-Go phase (ages 65–74), a slower Slow-Go phase (75–84), and a lower-mobility but high-healthcare No-Go phase (85+). This module lets you set a different monthly spending for each phase and compares the result against a naive linear model — revealing how much you’ve been mis-estimating.
The IRS requires Required Minimum Distributions (RMDs) from traditional 401(k) and IRA accounts starting at age 73 (SECURE 2.0 Act, 2023). These forced withdrawals push retirees into higher tax brackets — often costing $50,000–$200,000 in avoidable taxes over a retirement. This module uses the actual IRS Uniform Lifetime Table to calculate your RMD at each age, applies your federal bracket and state tax rate, and shows the real after-tax fund longevity vs. pre-tax projections. Roth IRA and taxable brokerage accounts are also modeled.
Claiming Social Security at 62 gives you benefits immediately — but permanently reduces your monthly payment by up to 30%. Waiting to age 70 increases your benefit by 24% above your Full Retirement Age (FRA) amount. The total lifetime difference between claiming at 62 vs. 70 can exceed $200,000. This module calculates the break-even age for each strategy (62 vs. 67, 67 vs. 70), models your fund longevity under each claiming age, and identifies the mathematically optimal strategy for your specific inputs.
A retirement plan built only on average returns is built on a lie — markets don’t deliver average returns in a straight line. Sequence-of-returns risk means a major crash in the first 2–3 years of retirement can permanently deplete your portfolio even if average returns fully recover over the next 20 years. Module 7 runs your plan through three simultaneous scenarios (pessimistic / base / optimistic) plus a sequence risk scenario (2008-style -30% or -50% crash in Year 1) and calculates the probability you will not outlive your money in each case. You can also set a legacy goal — a specific dollar amount to leave to heirs — and see what withdrawal rate preserves vs. destroys that target.

Your Pre- and Post-Retirement Timeline (Ages 55 to 73+)
Module 1 takes 60 seconds and immediately tells you how many years your retirement fund needs to last. Every other module uses this number automatically.
Why This Beats Standard Fiduciary &
Brokerage Calculators
Most free retirement calculators give you a single “will I run out of money?” number. This tool goes further — combining 7 integrated modules that cover personalized longevity, healthcare inflation, RMD tax exposure, Social Security timing, spending psychology, and market stress testing in one place. All free, all US-specific.

Wealth Management Tips:
Asset Location, Withdrawal Rates & Cash Buffers
These tips come from how financial planners, tax pros, and advanced DIY investors actually use longevity, healthcare, and RMD models in real client plans.
- Healthy, active non-smokers with long-lived parents often see estimates in the late 80s or early 90s.
- If your probability of being alive at 90 is over 30%, treat 90 as your minimum planning age.
- Re-run your plan at 5%, 7%, and 9% to see how sensitive your fund is to medical cost surprises.
- If a 2-point change breaks your plan, consider LTC insurance or trimming other spending.
- Start from your current budget, subtract work-only costs, then add new retirement costs (travel, hobbies).
- Keep lifestyle cuts limited; unrealistic cuts make the plan look better than you’ll actually follow.
- Check that your Go-Go years don’t quietly push your withdrawal rate above ~4–5%.
- Use the “vs. linear model” card to see how much more realistic your plan has become.
- Run one scenario with your current state, and another with a zero-tax state to see relocation impact.
- If the total tax burden is six figures, explore Roth conversions before age 73.
- Compare fund longevity across claiming ages, not just lifetime SS dollars.
- Use the break-even ages to decide if your health realistically supports waiting.
