Part seven: What is the “three Bucket Strategy” for Retirement Corpus?

Learn how to build your retirement corpus with the simple, intuitive, and easy to implement three Bucket Strategy.

Key takeaways.

The three Bucket Strategy offers a simple, intuitive framework for building a retirement corpus.

It is easy to implement, even for investors with limited expertise or time.

The three buckets are designed to balance growth, stability, and liquidity across your retirement portfolio.

In the previous articles of this retirement series, we covered how to estimate your retirement corpus and express it using the R factor.
The next step is understanding how to systematically build that corpus over time.

The three Bucket Strategy offers a simple yet effective framework to do exactly that.
It is easy to understand and implement, even for investors with limited time or experience, while still being robust enough to perform well across different market conditions.
The strategy has been tested through simulations covering a wide range of market scenarios.

The Framework: three Buckets, three Distinct Purposes.

Instead of treating your retirement savings as a single pool, the three Bucket Strategy divides it into three virtual buckets.
Each bucket serves a distinct purpose and is funded up to a certain level of R, your estimated annual retirement expense.
Together, these buckets are designed to balance growth, stability, and liquidity for your retirement corpus.

Below is a high level overview of the three buckets.
The next section explains how to fund each bucket, and the types of investments typically suited to them.
Detailed investment selection will be covered in a subsequent article.

The Three Buckets:.

Bucket one The Spending Bucket.

Target Level: 1R.

This bucket should hold one year of your retirement expenses.

Purpose:.

To fund your day to day living expenses during retirement.

Priority:.

Safety and liquidity are the primary priorities, as this bucket is used for regular spending.

Investments:.

This bucket should be invested in highly liquid, cash like instruments that are insulated from market volatility.
Suitable investment options will be discussed in the next article.

Bucket two The Income Protection Bucket.

Target Level: 5R.

This bucket should hold five years of retirement expenses.

Purpose:.

To act as a safety net by shielding five years of expenses from market volatility.
Combined with Bucket one, it creates a six year buffer that allows long term investments time to recover without forcing you to sell growth assets at depressed prices during market downturns.

Priority:.

Stability and protection from market volatility take precedence, followed by reasonable returns.

Investments:.

Conservative investments insulated from market swings, such as high quality medium duration bond funds, are well suited for this bucket.

Bucket three The Wealth Building Bucket.

Target Level:.

The remainder of your retirement corpus after allocating 6R to Buckets one and two.
For example, if your target corpus is 30R, then target 24R in Bucket three.

Purpose:.

This is the primary growth engine of your retirement portfolio and typically holds the largest share of your assets.

Priority:.

Long term growth is the key objective.

Investments:.

This bucket should be invested in high growth, high risk assets such as well diversified equity investments.

How to Fill Your Buckets.

Once you understand the role of each bucket, the next step is funding them.
The most effective approach is to fill the buckets in reverse order.
Start with long term growth (the Wealth Building Bucket or Bucket three) and gradually move toward near term needs (the Spending Bucket or Bucket one) as retirement approaches.
Below is a suggested timeline.

Phase one: More Than ten Years from Retirement.

Focus: Bucket three The Wealth Building Bucket.

When retirement is more than a decade away, time is your greatest advantage.
At this stage, it is generally appropriate to allocate all retirement savings to Bucket three, which forms the foundation of your portfolio.

Since the objective is long term growth, focus on a carefully selected and well diversified portfolio of equity mutual funds.
While equities can be volatile in the short term, they have historically delivered strong returns over long periods.

Phase two: Around ten Years from Retirement.

Focus: Bucket two The Income Protection Bucket.

As you enter your 50s, it becomes important to start building Bucket two.
While Bucket three (the Wealth Building Bucket) continues to drive growth, it is also subject to market volatility.
Greater certainty is needed to ensure your retirement expenses can be met regardless of market conditions.

A market downturn close to or during retirement primarily impacts Bucket three.
Without a properly funded Bucket two, you may be forced to withdraw from Bucket three at an unfavorable time, limiting its ability to recover.
A five year buffer of stable assets prevents this and provides peace of mind.

At this stage, begin shifting funds into Bucket two and aim to build it up to 5R, i.
e.
, five times your estimated annual retirement expenses.
Investment grade, medium duration bond funds are typically suitable for this purpose.

Phase three: two three Years from Retirement.

Focus: Bucket one The Spending Bucket.

As retirement approaches, ensure that Bucket one is fully funded with at least one year of expenses.
These assets should be completely insulated from market fluctuations.

This bucket should hold extremely safe and highly liquid investments such as liquid funds, short duration bond funds, or savings bank balances.
If required, funds can be gradually shifted from Bucket three to build this reserve, thereby reducing exposure to market volatility as retirement nears.

Real Life Adjustments.

The three Bucket Strategy is designed to be flexible.
The timelines and bucket sizes discussed above are guidelines and can be adjusted based on individual circumstances such as risk tolerance, pension income, or other financial goals.

To keep this discussion focused, personal customizations and withdrawal strategies during retirement will be covered in separate articles.
Detailed investment options for each bucket will also be discussed in an upcoming article.

Final Thoughts.

The strength of the three Bucket Strategy lies in its simplicity and ease of implementation.
It requires minimal rebalancing until you are about ten years away from retirement.
The framework is intuitive, and using the R factor as a benchmark for each bucket provides clear visibility into how many years of expenses each bucket can support.
This clarity helps motivate disciplined saving during the accumulation phase and offers a practical way to assess how many years of retirement your corpus can fund once you retire.
