Retirement planning often focuses on projected returns.
But the more important variable may be structural withdrawal pressure.
Most retirement plans appear stable during strong markets. Few are evaluated under realistic stress.
The Simple Math Many People Overlook
If a portfolio may reasonably earn 5–6% over time, withdrawing 4% may allow sustainability to remain intact.
If withdrawals rise to 7–8%, particularly during volatile periods, structural pressure increases — and the math can begin working against you.
That difference compounds over time.
Retirement sustainability is not determined by a single return assumption. It is shaped by the relationship between earning capacity and withdrawal demand.
Why Sequence Matters
Returns rarely arrive evenly.
A negative year early in retirement, combined with ongoing withdrawals, can permanently reduce the capital base in ways that are difficult to recover later.
This is known as sequence-of-returns risk.
Even portfolios with strong long-term averages can experience early stress that alters long-term durability.
Longevity Extends the Equation
Retirement today may last 25–35 years — sometimes longer.
Small differences in withdrawal rates, inflation assumptions, or volatility exposure can compound significantly over that horizon.
Durability must be evaluated across decades — not short-term projections.
Learn More About the RSI™ Framework
The Retirement Sustainability Index™ (RSI™) is a structured analytical framework designed to evaluate these structural pressures through disciplined, scenario-based analysis.
It is not a calculator or downloadable form. It is a guided engagement process focused on understanding how withdrawal rates, hypothetical return assumptions, volatility exposure, longevity horizon, and portfolio structure interact over time.
