Saving for retirement

  • How likely your savings are to last — A probability, not a guess. Monte Carlo across 99 years of real market history — not a single average return.
  • Whether you're saving enough right now — Modeled from your actual paycheck: salary, taxes and FICA, spending, employer match, and what's left over invested each year.
  • Whether your rentals pull their weight — Rent, Schedule E operating costs, depreciation, and an eventual sale — taxed the way the IRS would.

Close to retirement

  • When to claim Social Security — Compare claiming ages side-by-side to see which strategy gives you the most lifetime income.
  • Whether Roth conversions make sense for you — And how much they could save in lifetime taxes.
  • How to bridge the years before 59½ — Model Roth conversion ladders, Rule of 55, and 72(t) withdrawals, with penalties priced in when a plan comes up short.

In retirement

  • How much you can safely spend each year — Without running out before you run out of time.
  • What healthcare costs before Medicare — ACA subsidies under the 2026 rules and IRMAA surcharges after 65, projected year by year.
