Where Your Money Goes

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 100

The 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

Example: Average household budget

$9,500 monthly income with balanced expenses

Total income: $9,500. Total expenses: $6,100. Monthly surplus: $3,400. Savings rate: 10.5%. You're saving $1,000/month across emergency, retirement, and general savings.

Frequently Asked Questions

What's the 50/30/20 budget rule?
The 50/30/20 rule suggests spending 50% of your after-tax income on needs (housing, food, utilities), 30% on wants (entertainment, travel, dining), and 20% on savings and debt payments. It's a simple framework for balanced budgeting.
How much should I save each month?
Financial experts recommend saving at least 20% of your income. This includes retirement contributions (15% for most people) plus emergency fund and other savings goals. If you can't save 20%, start with what you can and increase over time.
What's a healthy expense-to-income ratio?
Your total housing costs should ideally be under 28% of gross income, and total debt payments under 36% (the 28/36 rule). For overall expenses, keeping them under 80% of income (saving 20%+) is a good target.
How can I reduce my expenses?
Track every dollar for a month to find spending leaks. Common areas to cut: dining out, subscriptions you don't use, impulse shopping, and premium brands. Even small changes like brewing coffee at home can save $100+/month.
