- Build a zero-based budget in which every euro has a job
- Explain how envelopes, pay yourself first and Kakeibo work
- Match a budgeting method to a person's habits and income
Ana, 27, has tried budgeting three times. Each time she built a spreadsheet with 40 categories, and each time she gave up by week three. Her brother Matej keeps one rule on a sticky note and has saved every month for two years. Which method is best? Usually, the one you will still be using in six months.
50/30/20: a simple starting split
The was made popular by Elizabeth Warren and Amelia Warren Tyagi in their 2005 book All Your Worth. It splits your , the money you receive after tax and contributions, into three parts:
- 50% for must-haves: housing, energy, basic food, transport to work, insurance and minimum debt payments.
- 30% for wants: eating out, hobbies, travel, the nicer version of things.
- 20% for saving and extra debt repayment.
It is a rule of thumb, not a law. Where rents are high, must-haves often take more than half. Then many people use 60/20/20 for a while and keep looking for ways to lower housing costs or raise income.
Zero-based: every euro gets a job
In a , you plan the whole month before it starts. Income minus everything you plan to spend, save or repay must equal zero. “Zero” does not mean an empty account. Saving is a job too, so the money still builds up in your savings. The idea came from company budgeting and works well with a steady income.
Envelopes, pay yourself first and Kakeibo
The puts cash for each category in its own envelope. When the envelope is empty, spending in that category stops, or you knowingly move money from another envelope. Many banking apps now offer digital “pots” that work the same way.
means an automatic transfer moves your saving out on payday, before you spend anything. Spending tends to grow to fill the money you can see, so this protects your saving. The simplest version is 80/20: save 20% automatically and spend the rest without tracking categories.
is a Japanese household ledger, first published in 1904 by the journalist Hani Motoko. You write by hand, which slows you down. Each month starts with four questions: How much money do I have? How much do I want to save? How much am I spending? How can I improve? Spending goes into four groups: essentials, wants, culture (books, museums, courses) and unexpected.
How to choose
| Method | Often suits people who… | Watch out for |
|---|---|---|
| 50/30/20 | want a quick check | high rent breaks the 50% |
| Zero-based | want full control and have a steady income | it takes time each month |
| Envelopes | overspend in a few categories | carrying a lot of cash |
| Pay yourself first, 80/20 | hate tracking | it does not show where money leaks |
| Kakeibo | like writing and thinking things over | it is slower than an app |
Methods can be combined: many people pay themselves first and use envelopes for food and fun.
