What this sequence teaches

Over the first five years of this retirement (2006–2010), a 60/40 portfolio's cumulative real return was +13%. The single worst year in the tested window was 2022, when the 60/40 blend returned −22% in real terms.

Under the 4% withdrawal plan, the real portfolio balance bottomed out at $834,000 in 2008, before recovering in later years.

With a moderate first five years, this plan's outcome hinged more on the middle and later years of the sequence than on the start — a reminder that sequence risk is about the whole path, not just the opening years.

What RetireOdds actually simulates

The table above is the transparent skeleton: one portfolio, one withdrawal rule, one sequence of real historical returns, before taxes. It's meant to be checkable by hand.

Inside RetireOdds, the same year-by-year loop runs against your plan and adds what a real retirement actually has to deal with: federal and state taxes with account buckets (taxable, tax-deferred, Roth) drawn in order, Social Security claiming and its partial taxability, Required Minimum Distributions, healthcare costs (ACA subsidies before 65, Medicare and IRMAA after), Roth conversions, and one-time life events.

It also runs three engines instead of one: Monte Carlo (1,000 lognormal real-return paths calibrated to this same 1928–2023 dataset), a block bootstrap of this history, and the historical replay shown on this page. A plan fails if any year is unfunded — including the last one.

Read the full method on /methodology, walk through the product in the user guide, or try your own numbers in the free calculator.

Returns are approximate, rounded, planning-grade real (inflation-adjusted) totals for US large-cap stocks and 10-year Treasuries — this is educational modeling, not financial advice.
