How the calculator works
Add your monthly salary, then your fixed costs and everyday spending. The calculator adds them up, shows the money left, and compares the split with the 50, 30 and 20 guide. It is a quick estimate, not a bank statement.
Turn the estimate into a plan
When the numbers look right, start a real monthly plan in budgetbaba. Your figures stay in your own account, and you can track each bill and expense as it happens.
