Creating Your Budget
Step 1: Calculate Net Income
| Source | Amount |
|---|---|
| Salary (after EPFEmployees' Provident Fund — mandatory retirement savings fund for private-sector workers, APITAdvance Personal Income Tax — income tax withheld on employment income) | Rs. ______ |
| Side income | Rs. ______ |
| Rental income | Rs. ______ |
| Other | Rs. ______ |
| Total Net Income | Rs. ______ |
If you want to check the APITAdvance Personal Income Tax — income tax withheld on employment income and EPFEmployees' Provident Fund — mandatory retirement savings fund for private-sector workers deductions behind "net" salary, the income tax calculator shows your exact take-home pay from your gross salary.
Step 2: List All Expenses
Track for one month everything you spend.
Step 3: Categorize (Needs vs Wants)
Needs = Must have to survive and work Wants = Nice to have but can live without
Step 4: Calculate Percentages
Needs % = (Total Needs / Net Income) × 100
Wants % = (Total Wants / Net Income) × 100
Savings % = (Total Savings / Net Income) × 100Step 5: Adjust to Match 50/30/20
If needs > 50%: Find ways to reduce (cheaper rent, less transport) If wants > 30%: Cut discretionary spending If savings < 20%: Reduce wants first, then needs

"Should I budget weekly or monthly?"
Monthly works best for most Sri Lankans since salaries are monthly. However, track spending weekly to stay on course.
