What is Budget Calculator?
A budget calculator helps you create a detailed monthly budget by tracking all your income sources and expenses across multiple categories.
How It Works
Enter your monthly income and all your expenses by category. The calculator sums everything up, shows your surplus or deficit, savings rate, and visualizes where your money goes.
The Formula
Total Income = Take-Home Pay + Spouse Income + Other Income
Total Expenses = Sum of All Expense Categories
Monthly Surplus = Total Income - Total Expenses
Savings Rate = Total Savings / Total Income x 100The budget calculator sums all your income sources and expense categories, then calculates your monthly surplus or deficit. It also computes your savings rate (percentage of income saved) and expense-to-income ratio.
Examples
