New 'Bucket Strategy' Millions Are Using To Make Their Retirement Savings Last Longer

For years, retirement advice revolved around a single number: withdraw 4% of your savings each year, and your money should last about 30 years. It was simple, easy to explain, and widely adopted by planners and retirees alike. 

But retirement planning has become more complicated. People are living longer, and interest rates don't always behave the way they did when the rule was first developed.

That's one reason more retirees are exploring a newer approach known as the bucket strategy, which may help households avoid wasting money in retirement by organizing investments based on when the money will actually be needed.

Why the 4% rule is being reconsidered

The 4% rule traces back to research by financial planner William Bengen, who analyzed historical market data and found that withdrawing roughly 4% of a diversified portfolio annually had a strong chance of lasting three decades.

It worked well as a planning shortcut, but retirement today doesn't look exactly like it did in the 1990s. A few things have changed:

• Many people now spend 30+ years in retirement
• Market volatility has increased in certain periods
• Interest rates and bond returns can fluctuate significantly

Because of these shifts, some analysts now suggest retirees might start closer to 3.3% to 4% withdrawals, depending on their situation.

That doesn't mean the 4% rule is obsolete. However, many retirees today are looking for a system that feels more flexible and less tied to a single number.

What the retirement bucket strategy actually is

The bucket strategy takes a different approach. Instead of viewing your retirement savings as one big pool of money, the strategy separates your savings into several "buckets," each meant for a different stage of retirement spending.

The idea is simple: money you'll spend soon should be kept somewhere stable, while money you won't need for many years can stay invested for growth.

Most versions of this strategy use three buckets:

• Short-term spending
• Mid-term spending
• Long-term growth

Organizing savings this way may help retirees avoid selling investments during a market downturn just to cover everyday expenses.

Bucket 1: Money you'll need soon (0–3 years)

The first bucket is designed to cover near-term living expenses, which are typically one to three years' worth of spending.

This money is usually kept somewhere very stable because the goal isn't growth. The goal is access and reliability. Common places retirees store these short-term funds include:

• Checking account
• High-yield savings accounts
• Money market accounts
• Treasury bills or short-term government securities

For example, a retiree expecting to spend about $60,000 a year might keep $120,000 to $180,000 in this bucket.

That cushion can make a big difference emotionally. If the stock market dips, retirees know their next few years of expenses are already covered.

Bucket 2: Money for the next stage of retirement (3–10 years)

The second bucket sits in the middle. It's meant to fund expenses that will likely come up several years down the road.

Because the timeline is longer, retirees often place this money in investments that offer moderate growth with relatively lower volatility. Examples include:

• Bond funds
• Certificates of deposits
• Treasury notes
• Conservative balanced funds

Over time, funds from this bucket are moved into the short-term bucket as it gets used up. Think of it as a refill system that keeps the first bucket stocked.

Bucket 3: Long-term growth (10+ years)

The final bucket focuses on growth. This money may not be needed for a decade or longer, which gives it more time to ride out market ups and downs.

Because of that longer timeline, retirees often place this portion of their portfolio in investments such as:

• Stock index funds
• Dividend-paying stocks
• Real estate investments
• Growth-oriented mutual funds

Historically, stocks have delivered higher long-term returns than many other asset classes. Keeping part of a portfolio invested for growth can help offset inflation and extend how long retirement savings last.

Eventually, gains from this bucket are used to replenish the middle bucket.

Why many retirees like the bucket approach

One of the biggest advantages of the bucket strategy is psychological. When markets fall, it can be stressful to withdraw money from investments that are temporarily down. Some retirees panic and sell at the wrong time.

Having several years of expenses set aside can help reduce that pressure.

Potential downsides to keep in mind

Like any retirement strategy, the bucket approach isn't perfect.

Holding too much cash in the short-term bucket can expose retirees to inflation risk, since cash tends to grow slowly. You can miss out on significant market gains, leading to a "cash drag" over a 30+ year retirement.

Another challenge is that the strategy requires occasional adjustments. Over time, buckets need to be refilled and rebalanced based on spending and market performance.

Bottom line

The bucket strategy is gaining attention because it organizes retirement savings around when money will be needed, rather than relying entirely on a fixed withdrawal rate like the traditional 4% rule. By separating funds into short-, medium-, and long-term buckets, retirees may create a clearer plan for spending while keeping part of their portfolio invested for future growth.

Many retirees also overlook how guaranteed income sources fit into the strategy. Payments from programs like Social Security (one of the most valuable senior benefits available) can reduce the amount of savings needed in the short-term bucket, potentially allowing more money to remain invested for longer-term needs.
