Budget Calculator
Split income into needs, wants and savings by percentage.
How it works
Savings = income − needs − wants
The classic 50/30/20 rule: needs 50%, wants 30%, savings 20%. Adjust as needed.
Worked example
Monthly income 10,000 on 50/30/20:
- Needs (rent, food, transport, insurance) = 5,000
- Wants (entertainment, travel, subscriptions) = 3,000
- Savings and debt = 2,000
If rent alone is 40%, shift to 60/20/20 and protect savings first.
Notes and limitations
50/30/20 is a starting point, not a rule. High-cost cities push the "needs" share up; at lower incomes, build an emergency fund (3–6 months of expenses) before optimising investment ratios.
