The 50/30/20 rule: how to split your income and set spending limits
A simple way to divide your salary between needs, wants and savings — and how to turn it into clear limits for each category. · 5 min read
What the rule says
The 50/30/20 rule is one of the simplest ways to plan your income. Everything you receive after taxes is split into three parts: half for essential expenses, thirty per cent for wants, and twenty per cent for savings and paying off debt.
The numbers are a guideline, and adjusting them to your situation is perfectly fine. If rent alone takes more than half of your income, the proportions will shift. The real value of the rule is that it makes you treat savings as a fixed item rather than whatever is left at the end of the month.
What counts as a need and what as a want
The line is sometimes blurry, so it helps to agree with yourself in advance.
- Needs (50%): housing and utilities, basic groceries, commuting, phone and internet, medicine, minimum loan payments.
- Wants (30%): cafés and delivery, entertainment, clothes beyond the essentials, hobbies, travel, streaming subscriptions.
- Savings (20%): an emergency fund, saving for goals, paying off debt early.
An example with a 15,000 lei salary
Say you earn 15,000 lei a month. By the rule that is 7,500 lei for needs, 4,500 for wants and 3,000 for savings. If rent costs 5,000 and groceries plus transport another 3,500, your needs already total 8,500 — more than half. So you either cut wants to 3,500 or look for savings among the essentials, while still putting aside at least 10–15%.
Turning percentages into limits
Percentages are good for planning, but day to day it is easier to work with concrete amounts per category. Take your actual spending from last month and set limits on two or three categories that most often get out of hand — usually cafés, shopping and entertainment.
A good limit is a little below your usual spending, but not draconian. If you normally spend 1,500 lei a month in cafés, a 1,200 limit is realistic; 300 is not — you will break it in the second week and give up altogether.
Watch the pace, not only the total
The most useful thing is to see how you are doing against a limit during the month. If halfway through you have already used 80% of your entertainment budget, that is the signal to slow down now rather than be disappointed on the 30th. Moldonyan Finance warns you as you approach a limit and has a “Pace” chart that compares this month with the previous one up to the same day.
