How to Use This Monthly Budget Calculator
This free monthly budget calculator helps you track your income, expenses, savings, and debt payments in one place. You can add custom budget categories, edit your spending, and instantly see how much money is left over each month.
Step 1: Enter Your Monthly Income
Add your paycheck, side income, freelance income, or any other money you receive during a typical month.

List your needs, wants, savings, and debt payments. You can use the default categories or create your own custom categories.
Step 3: Review Your Budget Breakdown
The calculator shows your total income, total expenses, money left over, and how your budget compares to the 50/30/20 rule.
What Is a Good Monthly Budget?
A common budget guideline is the 50/30/20 rule:
- 50% for needs, such as rent, groceries, utilities, insurance, and transportation.
- 30% for wants, such as dining out, entertainment, shopping, and subscriptions.
- 20% for savings or debt payoff, such as emergency savings, retirement, credit cards, or student loans.
Your budget does not need to match this rule perfectly. The goal is to understand where your money goes and make better decisions based on your own income, expenses, and goals.
Why Use a Budget Calculator With Custom Categories?
Most budgets are too generic. A custom category budget calculator lets you track the expenses that actually matter to your life, whether that means childcare, pet costs, medical bills, hobbies, subscriptions, or irregular monthly spending.
