The Three-Bucket Strategy: How to Divide Your Portfolio by Time Horizon
Key takeaways
- The three-bucket strategy separates money into three time layers: short-term, medium-term, and long-term.
- The short-term bucket holds cash and savings accounts — liquidity comes first.
- The medium-term bucket can carry higher risk because you have time to recover from a downturn.
- The long-term bucket is for equity ETFs and compounding over decades.
- Separating the layers protects you from selling stocks at the wrong time due to an urgent cash need.
The three-bucket strategy divides an entire portfolio into three separate layers based on when and how quickly you need the money — and thereby reduces the risk of selling equities at the worst possible moment.
Why three buckets at all?
The most common investor mistake occurs when an unexpected expense arises in the middle of a market downturn. Without a clear separation you reach for whatever you have and sell an ETF at a loss simply because you have no cash on hand. Three buckets eliminate this trap by assigning each layer a distinct purpose.
First bucket: liquidity and calm in a crisis
The first bucket holds money you need within two years. This includes an emergency reserve of three to six months of expenses, funds for planned larger purchases, and a cash cushion for unforeseen events. Suitable instruments are savings accounts, term deposits, and money-market funds. Return is secondary — the priority is that the money is available quickly and without loss.
Second bucket: moderate risk, 3–7 year horizon
The medium-term bucket serves goals that are neither immediate nor distant — a flat renovation, a car replacement, a mortgage down-payment. A mixed allocation makes sense here: bonds, more conservative ETFs, or a combination of both. Volatility is tolerated because you have time to respond to a temporary decline.
Third bucket: compounding works for you
The long-term bucket is purely for investing — you do not need the money for at least 10 years. This is where global equity ETFs belong, such as funds tracking MSCI World or All-World. Time is the greatest advantage: compounding works in full here and short-term fluctuations cease to matter.
How to get started
- Map your expenses 12 months ahead — what will be needed?
- Set the size of each bucket based on your own plan, not generic tables.
- Reassess the allocation once a year or after a major life change.
- Use regular investing (DCA) for the third bucket.
The three-bucket strategy is not complicated, but it requires the discipline to keep separate "mental accounts" as real numbers too.
FAQ
What are the three buckets in investing?
It is a way of dividing a portfolio into three layers: short-term (cash, liquidity), medium-term (more conservative investments), and long-term (equity ETFs). Each layer carries different risk and serves a different purpose depending on when you need the money.
How much money should go into each bucket?
It depends on your personal situation. A general rule: the short-term bucket should hold three to six months of expenses, the medium-term bucket is sized according to planned goals, and the long-term bucket holds the rest of available investment funds. There is no universal ratio.
Do I need three physically separate accounts?
Physical separation helps — a savings account for the short-term bucket, an investment account for the long-term one. The middle bucket can sit in a separate portfolio. Without this separation, the temptation to mix the layers in a crisis is high.
