50/30/20 budget calculator
Split your monthly income by the 50/30/20 rule: needs, wants and savings/debt.
50% for needs (housing, bills, food), 30% for wants (leisure, subscriptions) and 20% to save and pay off debt. Adjust the percentages to your reality.
How the calculation works
The 50/30/20 rule is the simplest way to organize money without a spreadsheet: split your net income (take-home pay) into three buckets.
- 50% needs: housing, bills, food, transport, health.
- 30% wants: leisure, dining, subscriptions, travel.
- 20% future: saving, investing and paying off debt above the minimum.
Step-by-step example (income of R$4,000)
- Needs: 4,000 × 0.50 = R$2,000
- Wants: 4,000 × 0.30 = R$1,200
- Future: 4,000 × 0.20 = R$800
When it doesn't fit
If needs exceed 50%, cut fixed costs — housing is usually the biggest. If there's slack, raise the 20%.
Examples
- Income R$3,000: R$1,500 needs, R$900 wants, R$600 future.
- Income R$8,000: R$4,000 / R$2,400 / R$1,600 — higher earners can aim above 20%.
Frequently asked questions
Does the rule fit any income?
It is a guide. On lower incomes needs weigh more; on higher ones you can save well above 20%. Use it as a reference, not a law.
Which bucket is debt?
Minimum payments are needs; extra payoff effort is part of the 20% (building your future).
Gross or net income?
Net — what actually lands in your account, after taxes and deductions.
