Backtest detail
How this is calculated
This is a real historical backtest. We run your plan through every retirement-length window in US market history (1871โ2022): a 75% stock / 25% bond portfolio, rebalanced annually, with withdrawals raised each year for that period's actual inflation. The success rate is the share of those historical start years in which the money lasted the full length without running out.
Your confidence level sets the bar: at Balanced (90%), a survival rate of 90% or more reads "You can retire here", within 10 points below is "Close โ worth a closer look", and lower is "Not quite yet". The same level sizes the "Needed to retire here" target. Retirement length also drives it โ early retirees planning 40โ50+ years see lower survival than the 30-year baseline.
