How to Use the Budget Calculator

This tool helps you understand how much of your income is being used, saved, or overspent each month. By comparing your earnings and expenses, you can identify opportunities to improve financial balance. Aim to keep your essential expenses under 50%, discretionary spending under 30%, and savings or debt repayment around 20% — the classic 50/30/20 rule.
