How Does a Budget Calculator Work?
The calculator works on a simple principle:
Income – (Fixed Expenses + Variable Expenses + Savings Goal) = Surplus or Shortfall
Let’s break it down 👇
Understanding Income and Expenses
Income: This is your monthly take-home amount after tax (salary, freelance income, business profits, etc.).
Fixed Expenses: Bills that remain constant each month — rent, EMIs, utilities, subscriptions.
Variable Expenses: Expenses that change every month — groceries, dining out, entertainment, shopping.
Savings Goal: The amount you want to save each month.
How the Calculator Breaks Down Your Budget
Once you enter all the details, the calculator instantly:
Totals your monthly expenses.
Subtracts them from your income.
Calculates whether you have a surplus (extra money) or a shortfall (deficit).
Suggests how much you should save for emergencies.
Projects your savings for the selected number of months.
All of this happens within seconds — displayed clearly on screen with icons, pie charts, and even social share options!
Step-by-Step Guide to Using the Budget Calculator
Let’s walk through each step of using it — in plain English.
Step 1: Enter Your Monthly Income
In the first box, type your total take-home income per month.
👉 Example: ₹60,000.
This tells the calculator how much money you have available to manage all your expenses and savings.
Step 2: Add Fixed Expenses
Now enter all your regular monthly commitments, like:
Rent or home loan EMI
Utility bills (electricity, gas, water)
Internet or phone plans
Insurance premiums
Subscriptions (Netflix, gym, etc.)
👉 Example: ₹25,000.
Step 3: Add Variable Expenses
These are the costs that change month to month:
Groceries
Fuel or travel
Dining out
Shopping
Entertainment
👉 Example: ₹15,000.
Step 4: Enter Your Savings Goal
If you want to save a certain amount every month, enter it here.
It could be for investments, travel, or emergency savings.
👉 Example: ₹10,000.
Step 5: Choose Emergency Fund Duration
Enter the number of months of expenses you want in your emergency fund.
Financial experts recommend at least 6 months.
👉 Example: 6.
Step 6: Select Planning Period
This defines how many months you want to plan ahead.
For instance, a 12-month plan shows your yearly savings potential.

Step 7: Click “Calculate Budget”

You’ll see a progress bar fill up for 15 seconds — simulating a smart calculation process.
Once completed, your results and pie chart will appear instantly.
Understanding the Results
Once the calculation is done, the Budget Calculator displays a detailed breakdown:
Total Monthly Expenses
This is the sum of your fixed and variable costs.
👉 Example: ₹25,000 + ₹15,000 = ₹40,000.
Monthly Surplus or Shortfall
This shows how much money remains after expenses and savings.
👉 Example:
Income = ₹60,000
Total Expenses = ₹40,000
Savings = ₹10,000
Surplus = ₹10,000
If it’s negative, you’re overspending and need to cut back on variable costs.
Emergency Fund Target
The calculator also shows how much you should ideally keep aside as an emergency fund.
👉 Example: ₹40,000 (monthly expenses) × 6 months = ₹2,40,000.
Projected Savings
It calculates how much you’ll save over the chosen planning period.
👉 Example: ₹10,000 (monthly savings) × 12 months = ₹1,20,000.
Visual Insights: Budget Pie Chart
After the results appear, the calculator automatically creates a pie chart showing your expense distribution:
