About This Tool
What Is a Budget Calculator?
A budget calculator organises monthly cash flow into income, essential expenses, flexible spending, debt payments and savings.
A monthly budget is more useful when it reflects the money you actually receive and spend. This calculator totals your after-tax income, subtracts fixed and variable expenses, then accounts for planned savings and investments. The result is the amount left over at the end of the month.
The tool also shows three useful percentages: your expense ratio, savings rate and debt-to-income ratio. These figures help you understand whether most of your income is going toward living costs, future goals or debt obligations.
For a realistic plan, use average monthly figures from recent bank statements instead of guessing from a particularly expensive or unusually quiet month.

Popular Budget Framework
The 50/30/20 Budget Rule
A common starting point is to direct approximately 50% of after-tax income toward needs, 30% toward wants and 20% toward savings or debt reduction. It is a guideline rather than a rule, so adjust it to suit your income, location and priorities.

How to Improve Your Monthly Budget
Separate Needs from Wants

Plan for Irregular Costs
Divide annual insurance, maintenance, subscriptions and other occasional bills into monthly amounts.
Track Progress Monthly
Compare your planned budget with real spending and adjust categories that are consistently too low or too high.
