The 50/30/20 rule: how to split your pay simply
What the 50/30/20 rule is, how to apply it to your take-home pay with a real example and what to do if your fixed costs don't fit in 50%.
Making a budget sounds like a spreadsheet with fifty rows. The 50/30/20 rule is the opposite: three boxes and a percentage for each. It isn’t perfect, but it’s a good starting point if you’ve never organised your money.
The three parts
- 50% for needs: what you have to pay no matter what. Rent or mortgage, utilities, internet, groceries, getting to work, insurance and the minimum on any debt.
- 30% for wants: what you enjoy but could cut. Eating out, going out, trips, clothes you don’t need, subscriptions.
- 20% for savings: your safety net, your goals and anything extra you pay to clear debt sooner.
The percentages apply to your take-home pay, what actually lands in your account each month.
An example with numbers
With a take-home pay of €1,850 a month:
| Part | % | Per month |
|---|---|---|
| Needs | 50% | €925 |
| Wants | 30% | €555 |
| Savings | 20% | €370 |
If you get bonus payments, you can split them the same way or put them all into savings.
What if my needs go over 50%?
It’s very common, especially with high rents. That’s fine: the rule is a reference, not a law. Some options:
- Start with 60/30/10 or 60/20/20 and adjust over time.
- Review the fixed costs you can change: energy, phone or insurance plans you haven’t compared in years.
- Trim wants before you trim savings.
The budgeting guide from Finanzas para todos (Spain’s securities regulator and central bank) recommends exactly that: treat savings as one more fixed cost, to build an emergency fund and reach your goals.
The trick that works
Set savings aside as soon as you’re paid, not whatever’s left at the end of the month. There’s rarely anything left. If you move it to another account or a goal the day your pay comes in, you spend the rest of the month with what remains without thinking about it.
And to avoid overspending on wants without noticing, a daily number helps: what’s left this month divided by the days to go.
