How Ratcheting Withdrawals Can Unlock More Retirement Income

The 4% Rule in Retirement Withdrawals

The traditional 4% rule has guided retirees for decades and remains one of the simplest ways to structure withdrawals without depleting savings too quickly. Under this rule, retirees withdraw 4% of their portfolio in the first year and then adjust that dollar amount each year for inflation. For example, a $40,000 withdrawal at 3% inflation becomes $41,200 the following year. Research shows that about 96% of retirees who follow this rule end up wealthier than when they started because the rule is intentionally conservative. The tradeoff is that many retirees spend far less than they could, undershooting their lifestyle potential.

Ratcheting Withdrawals Strategy Explained

Michael Kitces’ ratcheting withdrawals approach offers a more flexible path, allowing retirees to increase their income when markets perform well while preserving the safety of the 4% rule during downturns. The strategy begins with the same 4% withdrawal but adds one key enhancement: if the portfolio grows to 150% of its starting value, withdrawals increase by 10%. This ratchet can only occur once every three years to avoid emotional overreaction to short-term market swings. If markets do not reach the threshold, withdrawals default to the traditional rule. The method captures upside without exposing retirees to unnecessary risk.

Practical Example of Ratcheting Withdrawals

Consider a $1 million portfolio. The first-year withdrawal is $40,000. After inflation adjustments, withdrawals rise slowly—around $43,700 after four years. But if the portfolio grows beyond $1.5 million, the withdrawal jumps permanently to roughly $48,000. Over a 30-year retirement, this additional income can compound into tens or even hundreds of thousands of dollars extra spending compared to a retiree who sticks with the inflation-only adjustments.

Historical Performance of Ratcheting Withdrawals

When tested against historical market cycles, the ratcheting strategy performed especially well during strong return sequences. Retirees starting in years like 1982 would have seen multiple ratchets as portfolios boomed. In weak markets, the strategy simply never triggers the ratchet, reverting to the safety of the 4% rule. In every case, retirees maintained the security of not outliving their assets while gaining the chance to enjoy more lifestyle upgrades in good markets.

Pros and Cons of Ratcheting Withdrawals

Ratcheting withdrawals shine in their ability to deliver more income when markets support it. The strategy is straightforward and avoids complex models. But the 150% threshold is somewhat arbitrary, and increasing withdrawals permanently introduces the risk of higher spending just before a downturn. While rare historically, future markets might behave differently. Still, for many retirees, the cautious flexibility of ratcheting creates a more fulfilling retirement without compromising safety.

Dynamic Spending with Permanent Cuts Strategy

A contrasting approach begins with higher withdrawals, 5% or even 6%, but requires permanent cuts if markets decline. After a negative year, spending is reduced by about 3% and never increases again. This strategy front-loads lifestyle spending but demands discipline during difficult periods. Its success depends heavily on a retiree’s comfort with uncertainty and their willingness to adjust downward when necessary.

Comparison of Withdrawal Strategies

The 4% rule is simple, conservative, and consistent, but often leads to leaving too much money unspent. Ratcheting withdrawals strike a middle ground by preserving safety while rewarding strong market performance. Dynamic spending allows for higher initial income but risks lifestyle compression if markets struggle. Each method reflects a different risk tolerance, and retirees may blend elements from multiple models.

The Importance of Adaptability in Retirement Planning

Rigid withdrawal rules fail to capture the realities of modern markets and evolving retiree needs. Dynamic strategies, such as ratcheting or permanent cuts, reflect real-world volatility and offer retirees more control over their financial futures. The 4% rule remains a useful starting benchmark, but long-term security improves when retirees adapt rather than adhere to a single number forever.

Retirement Planning in Context

Discussions around retirement strategies often include misconceptions about needing a million-dollar portfolio or perfect timing. Understanding both historical data and personal objectives helps retirees make informed decisions that align with lifestyle, risk tolerance, and longevity expectations. Thoughtful planning, and a willingness to adjust, remains the strongest strategy of all.
