The 50/30/20 rule: a simple budget that works

The 50/30/20 rule is a simple but effective way to divide your net income into three groups — so you finally know how much you can spend and how much to put aside.

How the 50/30/20 rule works

Fifty percent of your income goes to essentials — housing, food, utilities and transport. Thirty percent to the things you want: entertainment, hobbies or travel. The remaining twenty percent goes to paying off debt and saving. It is based on your net income, the amount that actually lands in your account.

How to adapt it

The percentages are not set in stone. Where housing is expensive, essentials may easily take 60% and wants less. What matters is the principle: consciously separate needs from wants and always keep part of your income for saving. Don't be afraid to adjust the rule to your needs and priorities.

Common mistakes

The most common mistake is hiding wants among needs — subscriptions, food delivery or impulse buys. It helps to split expenses into categories and, after a month, look at where the money actually went. Only real numbers show whether you are sticking to the rule.

In Výdaje online you can set monthly limits (goals) for your needs and wants groups, and the app keeps track of how much is left in each.
