100-YEAR HISTORICAL STRESS TEST
Would this plan have survived past markets?
Run the retirement part of your plan through every complete 40-year S&P 500 sequence across 100 calendar years, from 1926 to 2025. Returns include reinvested dividends and are adjusted by your inflation assumption.
0 of 61 complete historical retirement cohorts ran out of money before age 95.
Tested 61 complete sequences from 1926–2025. A “failure” means the invested balance reached zero before the end age. This simplified test treats the retirement pot as 100% invested in the S&P 500, deducts spending yearly, applies State Pension income, and excludes tax and fees.
