How to Split Your Income: the Bucket System
Money without a plan spends itself. The bucket system decides in advance where each paycheck goes, so you do not decide it from scratch every time.
The idea
You divide every income into a few parts with a clear purpose and move them on the day the money arrives. Allocate first, spend after — not the other way round.
“Pay yourself first” works because saving what is left almost never happens: nothing is left.
Four buckets
- Living. Essentials: housing, food, transport, phone, health.
- Investments. Money that works for the future and stays untouched for years.
- Emergency fund. A reserve for the unexpected: job loss, illness, urgent repairs.
- Fun. Guilt-free spending. This bucket is what keeps the system from falling apart after a month.
Which percentages to choose
There are no uniquely correct numbers. A well-known starting point is the 50/30/20 rule: half for needs, 30% for wants, 20% for savings. Our splitter defaults to a more savings-heavy version: 55% living, 25% investing, 10% emergency fund and 10% fun.
If those shares are out of reach right now, start small: even 5–10% into savings beats nothing. Raise the share every time your income grows.
Enter your income and tune the percentages.
Income Splitter →Emergency fund first
An emergency fund is three to six months of expenses in an account you can access quickly and where the money does not lose value. Its job is not returns but making sure a hard moment does not force you to sell investments at a loss or take on debt.
Once the fund is full, its percentage moves to investing.
What about debt
Expensive debt — credit cards, consumer loans — is usually better paid off before investing. Its interest rate is typically higher than the return you can expect from investments. A small emergency fund is still worth keeping meanwhile.
How to stick with it
- Automate. Transfers to each bucket on payday, with no manual decisions.
- Separate the money physically. Different accounts or cards for each bucket.
- Review twice a year. Income and life change, and the percentages can too.
