FAQs

What is the 50/30/20 budget rule?

The 50/30/20 rule allocates 50% of your income to needs (housing, food, transport, utilities), 30% to wants (entertainment, dining, shopping), and 20% to savings and debt repayment. It is a popular guideline for building a balanced budget.

How do I calculate my net budget surplus or deficit?

Net = Total Income - Total Expenses. A positive net means you have a surplus you can put toward savings or investments. A negative net indicates a deficit, meaning your expenses exceed your income and you need to cut spending or increase earnings.
