Runs 5,000 scenarios to show the real probability your savings last through retirement — with a full diagnostic dashboard showing exactly what's working and what needs attention.
Model the loss of one spouse during retirement — often the biggest real-world risk to a couple's plan.
When checked, some simulations include losing one spouse during your plan: Social Security drops to your "kept if widowed" % and your pension drops to its survivor % (set below).
This is an educational estimate, not financial advice or a green light to retire. The 5,000 simulations vary both market returns and inflation year to year, assume your fixed income keeps pace with only part of inflation (many pensions have no COLA), and — if you check "planning as a couple" — model the chance of losing one income stream later in life. It does not account for taxes or every real-world variable. Always confirm your plan with a licensed financial advisor before acting.
Most retirement tools give you one tidy "you'll have $X" number that assumes steady returns — which never actually happens. This one runs thousands of market scenarios, good years and bad, and reports the probability your savings last your full retirement. You get a realistic success rate instead of false certainty, so you can plan around real risk.
A low success rate is information, not a verdict — and you have levers. Try spending a little less, working or earning part-time a bit longer, delaying Social Security to raise your guaranteed income, or adjusting your investment mix. Change one input at a time to see what moves the number most; small shifts often help more than you'd expect.
Enter the expected net proceeds — what's left after selling costs and paying off any mortgage — as part of your savings, since that's money you'll have available for retirement. If you plan to buy another home, only count the leftover difference. Don't include a home's value if you intend to stay in it; this tool models spendable assets, not your residence.
It's named after the famous Monte Carlo casino. Like games of chance, the method runs a huge number of random trials to find the odds of an outcome. Rather than making one guess about future returns, it simulates thousands of possible market paths — booms, busts, and everything between — then reports how often your money lasts.
Your retirement simulation accounts for healthcare inflation — but the right Medicare plan can significantly reduce what you actually pay. These free resources help you compare plans before your enrollment window opens.
