Once you see the value of separating savings by purpose, the instinct is often to go too far the other way — a bucket for every category imaginable, until managing the buckets becomes its own chore. The useful version of this sits somewhere in between.

A reasonable starting point

Most people's savings goals fall into three broad types: a buffer for the unexpected, a near-term goal with a rough timeline (a trip, a purchase, a specific expense coming up), and a longer-term goal without a fixed date. Starting with one bucket for each of those, rather than one per individual want, tends to cover the actual need without turning savings into a spreadsheet project.

When it makes sense to add more

A new bucket earns its place when it represents a genuinely distinct goal with its own timeline or purpose — not just a subcategory of an existing one. If you find yourself unable to describe what a bucket is for in one short sentence, it's usually a sign it should be merged into a broader one instead of standing alone.

The test that tends to work well: could you explain, in one sentence, why this money is separate from your other savings? If yes, it's probably worth its own bucket. If the answer takes a paragraph, it probably isn't.
