Budget Planner for Sri Lanka
A budget is a plan for your money before the month starts. Done well, it shows you where the money goes and leaves room for savings. Here is a simple way to plan a monthly budget in rupees.
How to plan a monthly budget
- Add up your take-home income for the month.
- List your fixed costs: rent or housing loan, school fees, insurance, phone and internet, vehicle instalments.
- Estimate variable costs from the last two or three months: groceries, fuel or bus fares, electricity and water, eating out.
- Set a savings amount first, not with whatever is left over.
- Make sure the total is not above your income. If it is, trim variable costs before touching savings.
The 50/30/20 rule
A common starting point is to split take-home income into needs, wants and savings. It is a guide, not a law, and many families adjust it.
| Share | Goes to | Example on LKR 150,000 |
|---|---|---|
| 50% | Needs: housing, food, transport, bills | LKR 75,000 |
| 30% | Wants: eating out, hobbies, outings | LKR 45,000 |
| 20% | Savings and debt repayment | LKR 30,000 |
The figures above are an illustration only. If your needs already take more than half of your income, start with the needs you can reduce and a smaller, steady savings amount.
Common budgeting mistakes
- Forgetting yearly costs such as insurance, school registration, festival spending and vehicle revenue licences. Divide them by 12 and set that money aside monthly.
- Leaving out small daily spending, which adds up.
- Making the budget so tight it is abandoned in week two.
- Never comparing the plan with what actually happened.
