Your take-home pay after tax, per month
Needs 50%
—
The essentials you can’t skip: rent or mortgage, groceries, utilities, insurance, transport, minimum debt payments.
Wants 30%
—
The fun stuff: dining out, subscriptions, hobbies, travel, shopping — everything that makes life nicer but isn’t essential.
Savings & Debt 20%
—
Your future: emergency fund, investing, retirement, and extra debt payments beyond the minimums.
A guideline, not a law — adjust the percentages to your own situation. Nothing is stored or tracked. Not financial advice.

Start from net income
The rule works with your take-home pay — what actually lands in your account after tax. That’s the number you can genuinely divide, and it keeps the budget honest from day one.
Three buckets, zero spreadsheet stress
50% covers needs, 30% covers wants, 20% goes to savings and extra debt repayment. Popularised by senator Elizabeth Warren, it’s deliberately simple: three numbers you can remember, not thirty categories to maintain.
A starting point, not a straitjacket
High rent? Aggressive savings goal? Shift the split — 60/20/20 or 50/20/30 are fine too. The point is that every euro (or dollar) gets a job before the month starts.
Good to know before you calculate.
