The Floor-and-Ceiling Retirement Income Strategy

Comments Off on The Floor-and-Ceiling Retirement Income Strategy

One of the hardest parts of retirement isn’t just leaving work — it’s replacing a steady paycheck with income that’s anything but steady. Markets fluctuate. Expenses come in waves. And the future is always uncertain. Retirees often find themselves stuck between two fears: spending too much and running out of money… or spending too little and missing out on the life they saved for.

The floor-and-ceiling retirement income strategy is a flexible retirement income system that sets a safety net to protect your essentials (the floor) and a cap to prevent overspending (the ceiling). Within those limits, your income can adjust based on market performance—giving you the ability to adapt without overreacting.

What is the Floor-and-Ceiling Strategy

The floor-and-ceiling strategy is a rules-based retirement withdrawal approach that sets two key boundaries:

  • The Floor: The minimum amount of income a retiree needs to cover a minimum desired level of spending. This could be non-negotiable, essential living expenses—such as housing, food, healthcare, and insurance or can include additional expenses that you want to be able to cover.
  • The Ceiling: The maximum amount a retiree will spend in a given year, even if market returns are strong.
  • The Adjustment: Annually, your spending is adjusted based on certain metrics such as spending a fixed percent of the current portfolio. 

In good years, spending can rise (but not above the ceiling).

In bad years, it may fall (but not below the floor).

How It Works in Practice

  • Determine the Floor
    • Calculate the minimum annual income needed to maintain a basic standard of living.
    • This strategy can include levels of income outside of just the portfolio like:
      • Social Security
      • Pensions
      • Annuities
    • The floor can be adjusted for inflation
  • Set the Ceiling
    • Establish a cap for discretionary spending. This figure should be high enough to allow enjoyment in good years, but not so high that it risks long-term depletion.
    • The ceiling can be adjusted for inflation.
  • Link Withdrawals to Portfolio Performance
    • Most implementations use rules such as:
      • If the portfolio grows more than X%, increase next year’s income by Y% up to a maximum of the ceiling value.
      • If it declines more than Y%, reduce income by Y% down to a minimum of the floor.
  • Reassess Regularly
    • Re-evaluate the floor and ceiling every few years to account for inflation, changes in lifestyle, and updated longevity projections.

How It Works in Practice

Let’s assume a retiree with a $1 million portfolio and the following setup:

  • Initial withdrawal target: $40,000 
  • Floor: $28,000 which represents a 30% reduction
  • Ceiling: $52,000 which represents a 30% increase
  • Adjustments: Annually, the spending rate is adjusted to match 4% of the current portfolio
    • If the portfolio value increases to $1,200,000, the new withdrawal is $48,000 per year. As this is below the ceiling, that would be the new withdrawal. If the portfolio value increases again to $1,500,000, 4% of the portfolio value is $60,000 which is above the ceiling. The retiree would set their withdrawals at $52,000. 
    • If the portfolio value decreases to $800,000, the new withdrawal would be $32,000. They are above the floor at this point. If it subsequently drops to $600,000, 4% of the current value is $24,000 which is below the floor. They would now take $28,000 as their withdrawal. 

It’s important to consider the implication of this over the course of a retirement.

This chart shows how a retiree’s annual spending could change over 30 years, depending on how well their investments perform. It uses 250 different retirement scenarios, grouped into percentiles (from the best to the worst outcomes).

What the lines mean:
  • Orange (95th percentile): The best-case retirements — people could spend the most, often hitting the top limit (ceiling) of what they allow themselves to spend.
  • Blue and Green (75th and 50th percentiles): Average retirements — spending stays steady or slowly declines over time.
  • Teal and Purple (25th and 5th percentiles): Tougher retirements — spending drops quickly and levels out at the minimum (the floor), especially in poor market conditions.
