How to Calculate Your Budget by Income and Expenses

What is Budget Calculator?

A budget calculator is a digital tool designed to help you allocate your income across essential expenses, wants, and savings with clarity. By entering your earnings and expense categories, it instantly displays where your money goes each month. This approach empowers families, students, and professionals to manage personal finances and avoid overspending.


Using a budget calculator reduces money anxiety and brings visibility to spending patterns. It simplifies complex calculations and provides a snapshot of your finances—making financial planning much easier. With Vedantu’s online interface, updating values and testing scenario changes is seamless, even on mobile devices.


Formula Behind Budget Calculator

The most common budget formula compares your income to the sum of all expenses: Savings = Monthly Income − Total Expenses. Additionally, popular budgeting methods such as the 50/30/20 rule allocate 50% of income to needs, 30% to wants, and 20% to savings. The calculator displays a percent breakdown for each expense and instantly identifies overspending.
