The Zero-Based Budget Calculator estimates a cost estimation estimate for your scenario from the quantities, rates, period, units and other assumptions requested on the page. Replace the example values with your own zero based budget figures and recalculate after changing an assumption. Use it to compare scenarios, then verify any current rate or fee before acting.
Fill in each income and expense category. The system will show the balance and the ratio to income, adjusted until the balance = 0.

Zero-based budgeting is a budgeting system where every baht of income is allocated to a specific purpose. Total income - expenditure for all categories (including savings) = 0, so no money floats around without a purpose.
How is Zero-based budgeting different from 50/30/20?
The formula 50/30/20 divides the budget broadly into 3 groups, but Zero-based budgeting specifies details for every subcategory, making it clearer where money goes.
What does a negative balance mean?
A negative balance means you're planning to spend more than you earn in that month, so you're going to have to cut some expenses or find ways to increase your earnings before the month starts.
Should we do zero-based budgeting every month?
It's recommended to do this every month because monthly expenses vary. For example, if you have a long holiday, a wedding, or have to pay your annual bill, you should plan at least 1 weeks in advance.
Disclaimer: The result is a preliminary budget plan. Actual expenditure may differ from the plan.

How to use the Zero-Based Budget Calculator
Use this page to test a specific zero based budget scenario. Enter your own values in the calculator above, review the units beside each field, and recalculate after changing an assumption. The result updates the zero-based budget estimate instead of relying on a generic example.
Build a baseline zero based budget case with figures that match your situation.
Run a second zero based budget case after changing the rate, period, quantity or other key assumption.
Record the difference between the two zero based budget results and the input responsible for it.
Inputs for the zero based budget estimate
For this zero based budget calculation, check the quantities, rates, period, units and other assumptions requested on the page. The result is designed to show a cost estimation estimate for your scenario, not a guaranteed provider price or official decision.
How the zero based budget result is calculated
The calculator combines the entered quantities, rates and fixed costs to produce the displayed estimate. Reusing the same zero based budget inputs will produce the same estimate, which makes the page suitable for controlled scenario comparisons.
Checks for a zero based budget decision
Confirm any current rate, threshold or provider rule that could change the final amount. For zero based budget, Use the result as a planning estimate and confirm any rate, rule or threshold that may have changed before acting. Recheck the entered values and units if the result looks unexpected.
