A budget is the most powerful financial tool available to everyone — regardless of income. Our monthly budget calculator helps you track your income against all expenses to instantly reveal how much you have left to save and invest each month.
What is a Monthly Budget Calculator?
A monthly budget calculator is a personal finance tool that compares your monthly income against your categorised expenses to show your net surplus or deficit. It helps you identify where money is being spent, find areas to cut costs, and build a structured savings habit — the foundation of all financial progress.
Formula
Total Expenses = Housing + Food + Transport + Utilities + Miscellaneous
Monthly Savings = Monthly Income − Total Expenses
Savings Rate (%) = (Monthly Savings / Monthly Income) × 100
Example Calculation
Monthly Income: ₹60,000. Rent: ₹15,000. Groceries: ₹8,000. Transport: ₹3,000. Utilities: ₹2,500. Misc: ₹6,000.
- Total Expenses = ₹15,000 + ₹8,000 + ₹3,000 + ₹2,500 + ₹6,000 = ₹34,500
- Monthly Savings = ₹60,000 − ₹34,500 = ₹25,500
- Savings Rate = (₹25,500 / ₹60,000) × 100 = 42.5%

FAQs
How much should I save from my salary in India?
Financial planners recommend saving at least 20% of your income. If you have loans, aim for 30%. Automate savings through SIPs, PPF, and RD at the start of the month before spending.
What is the 50/30/20 budgeting rule?
Allocate 50% of after-tax income to necessities (rent, food, EMIs), 30% to wants (dining, entertainment, shopping), and 20% to savings and investments.
What should I do if my expenses exceed income?
Audit discretionary spending first (eating out, subscriptions, shopping). If that's not enough, consider income-boosting options like freelancing, and review high fixed costs like rent.
