The budget calculator brings your income, expenses and savings into one view, organised by category. It shows your monthly cash flow at a glance and helps you see how much is left to save after costs.
How the calculator works and what it’s for▾
How a budget is built
A budget comes from subtracting your expenses from your income. The difference tells you whether the month ends in the black or the red and how much you can put toward savings.
Splitting expenses into categories shows immediately which costs eat up the largest share of your income.
What you enter and get
You add your income and expenses by category, and the calculator totals your spending, the amount left over and your savings potential. You can also scan receipts to speed up tracking.
Who budgeting suits
The calculator works for anyone who wants to take control of their finances: students, families, savers and people paying down debt. It makes spending visible and makes setting goals easier.
Tips for a budget that works
Start by logging your real expenses over a few weeks so the budget is based on facts rather than guesses. Separate fixed costs like rent from variable ones like food and leisure, and you'll spot the easiest places to cut.
