The Retirement Runway Method

Manage retirement like a project.

Retirement Runway applies project-management disciplines—scope, baseline, risk, contingencies and change control—to the transition from earning income to managing a retirement plan.

Manage Review actuals, reforecast and make deliberate changes as conditions evolve.
The framework

Four stages. One retirement control system.

The method is intentionally sequential. Define what the retirement project must accomplish, establish and diagnose the baseline, protect the vulnerable years, then manage the plan as reality changes.

1

Define the project

Before testing the numbers, establish what retirement is expected to deliver.

  • Target retirement date and planning horizon
  • Essential, discretionary and irregular lifestyle costs
  • Reserve objective and major known obligations
  • Decision authority and backup plan manager
2

Establish the baseline

Translate the retirement scope into a year-by-year funding model, then identify where the current plan is strong and where it is exposed.

  • Reliable income and start dates
  • Portfolio resources and savings
  • Annual spending requirements
  • Planning assumptions and timing conventions
Long-Term Funding Do modeled resources extend through the planning horizon?
Retirement Runway Is the vulnerable retirement window supported?
Liquidity Bridge How much of the transition depends on market-exposed assets?
3

Protect the vulnerable years

Use the Baseline to focus protection where withdrawals, remaining horizon and portfolio exposure combine.

  • Identify the vulnerable retirement window
  • Separate near-term runway from long-term growth capital
  • Test practical adverse scenarios
  • Define contingency levers before they are needed
4

Manage the plan

Retirement is not completed on the first day of retirement. The baseline becomes the control reference.

  • Compare actual spending and income against the plan
  • Monitor portfolio and runway conditions
  • Reforecast when assumptions materially change
  • Apply deliberate change control rather than reactive decisions
Decision gates

Do not advance the plan until the previous question is answered.

Gate 1 — Scope defined The retirement lifestyle, timing, horizon, reserve objective and major obligations are sufficiently clear to model.
Gate 2 — Baseline understood Long-Term Funding, Retirement Runway and Liquidity Bridge have been evaluated and the important vulnerabilities are visible.
Gate 3 — Protection established The vulnerable years have a defined funding approach and practical contingency responses rather than relying on a single average-return assumption.
Gate 4 — Operating rules established Review cadence, thresholds and change-control actions are defined before they are needed.
Three operating principles

The method is designed for decisions, not prediction.

Scope before numbers

A calculation is only useful when the lifestyle, dates and objectives it is testing are defined.

Pressure before prescription

Identify what actually constrains the plan before changing investments, spending or timing.

Control before certainty

The goal is not to predict every future year. It is to create a plan that can be monitored and adjusted.

Put the method to work

Start with definition. Then establish the baseline.

Retirement Runway is designed as a progression. Each step adds only the level of analysis needed for the next decision.
