The 3 Bucket Framework
Sort a physician household's money by time horizon into the Safety Net, the Wealth Engine, and the Accelerator.
What it is
The 3 Bucket Framework is Financial Fellowship's method for sorting a physician household's money by time horizon into three buckets: the Safety Net, the Wealth Engine, and the Accelerator.
The sorting question is when the money is needed, not what it is wanted for. That distinction is the entire framework. Sorting by desire produces a budget. Sorting by time horizon produces an allocation, because how long a dollar can sit untouched is what determines where that dollar can live.
Physician cash flow arrives as a step, not a curve. Income multiplies in a single July, and the household is asked to make horizon decisions about a quantity of money it has never handled, in a year when the horizons themselves are all changing at once.
The three buckets
-
1
The Safety Net
Holds money the household may need soon, or without warning. Its job is availability, not return. It is the bucket that lets a household absorb a bad month, a broken contract, or a sudden change without selling anything or borrowing anything. Erosion is the price of admission and it is worth paying, because safety is what the household is buying.
-
2
The Wealth Engine
Holds money with a horizon long enough that short term movement genuinely does not matter. Its job is compounding, and it is the only bucket where time is doing most of the work.
-
3
The Accelerator
Holds money for the middle horizon, the named and dated things between now and the long term. A down payment, a practice buy in, a sabbatical, education funding. Its job is to arrive on schedule, which makes it the bucket most often filled with the wrong kind of asset.
Where it shows on the show
It applies any time a household is holding money and does not know where it belongs. That is more common in physician households than in almost any other, because a large cash balance sitting in a checking account is the default outcome of a sudden income increase.
It applies at the attending transition, when a household holds cash for the first time and has no rule for it. It applies when a household is arguing about a purchase. Most money arguments are horizon arguments in disguise.
It applies when a household is holding too much cash and knows it. Cash past the job of the Safety Net is not safety anymore. It applies before every large purchase, because the question "which bucket does this come from" prevents a household from funding a middle horizon goal by quietly draining the one bucket that keeps it stable.
Financial Health Assessment episodes built on the 3 Bucket Framework are listed here as they publish. Physician households can submit their own finances at financialfellowship.com/submit.
What it is not
It is not a portfolio, an asset allocation, or a recommendation to hold any specific investment. It is a sorting rule that gets applied before any of those questions get asked.
Not to be confused with the retirement "bucket strategy," which segments a retiree's portfolio by the years they will spend it. The 3 Bucket Framework sorts a working physician household's money during the earning years and is not a withdrawal or decumulation strategy.
Takeaways
- The sorting question is when the money is needed, not what it is wanted for.
- Safety Net: availability, not return.
- Wealth Engine: compounding. Time does most of the work.
- Accelerator: named and dated goals. Arrive on schedule.
- Not a portfolio, an asset allocation, or a withdrawal strategy.
Common questions
What are the three buckets?
The Safety Net, for money needed soon or unpredictably. The Wealth Engine, for money with a long horizon. The Accelerator, for the named and dated goals in between.
Is the 3 Bucket Framework a budget?
No. A budget sorts spending by category. The 3 Bucket Framework sorts money by when it is needed, which is a different question and produces a different answer.
How much belongs in the Safety Net?
Financial Fellowship does not publish a universal number, because the right size depends on how the household earns. Income stability, whether the household is employed or self-employed, and how many earners there are all change the answer.
Does the 3 Bucket Framework tell me what to invest in?
No. It tells a household what horizon each dollar has. What to hold for a given horizon is an investment question and belongs with a licensed professional who knows the household.
