50/30/20 budget

What is the 50/30/20 rule

A simple way to manage your salary: 50% to needs, 30% to wants and fun, 20% to savings or paying off debt.

Tip

It's a flexible starting point: adapt the percentages to your situation, but try never to skip the savings share.

Where the line between «need» and «want» falls

This is the part that sinks almost every budget, because most spending sits in the middle. The most useful test is not «could I do without it», but what would happen if you stopped paying it tomorrow: rent, utilities, basic groceries, the commute, compulsory insurance and instalments already signed cannot be stopped, and they belong to the 50%.

Everything else belongs to the 30%, even the things you are attached to: streaming subscriptions, the gym, restaurants, a new phone. The textbook case is the supermarket, which is both necessary and discretionary: the practical rule is to put in needs what eating simply would cost, and in wants the difference.

The 20% is not only saving

The third slice also covers paying off debt, and that changes the priorities. If you have a loan at 10% interest, every euro used to clear it returns 10% with certainty, a return no safe investment gives you. First you kill the expensive debt (revolving credit cards, small consumer loans), then you accumulate.

The one exception to keep ahead of everything else is the emergency fund: three to six months of necessary spending, in an account you can reach in a day. It is not an investment and it does not need to earn: it exists so a broken boiler does not become new debt.

Why percentages work better than a list

A line-by-line budget is abandoned in two weeks, because it requires recording everything. Three slices, instead, are checked with three numbers a month, and that is why the rule survives where spreadsheets die. The simplest way to make it actually work is to automate it: the day after payday, a standing transfer moves 20% to another account. What you do not see, you do not spend.

When the numbers do not add up

On a low salary or in an expensive city, 50% is not enough for the essentials, and that is not a personal failure: it is arithmetic. In that case the slice to defend is still the 20%, perhaps cut to 10%, because it is the only one that builds something; what shrinks is the 30%. On a high income the opposite happens, and 30% of wants becomes a sum there is no sense in spending every month: there the rule should be used the other way round, as a ceiling rather than a target.

And it applies to take-home pay, that is what actually lands in your account. Working from the gross figure throws everything off by a third.
