Retire Runway

Will the money last? Enter a household's ages, savings and contributions, spending, Social Security, pensions, mortgage and college goals, and your browser projects the plan year by year in today's dollars: a 1,000-path Monte Carlo probability of success against an 85% target, the retirement spending that hits it, the stress test (retire two years early, a 20% market drop, spending +20%, a longer life, long-term care), Social Security at 62, 67 or 70, and education funding, with checks for optimistic returns, a high withdrawal rate, old wills and missing life cover. A metered run turns first-meeting notes into the plan sheet without inventing a number, or writes the plan review - verdict, drivers, every stress test read, prioritised options to discuss - quoting only the page's figures. A planning model, not financial advice. Built on the SkillSafe skill @anthropics/financial-plan.
