How This Personal Budget Calculator Helps
This calculator helps you organize your monthly money by grouping common expenses into simple sections. Instead of guessing how much money may be left after bills, you can add income, regular bills, groceries, subscriptions, savings, transportation, and other expenses in one place.
Only monthly income is required to calculate. The expense sections are there to help you build a more complete estimate, but you can skip any optional section that does not apply to you.
Personal Budget Example
For example, if your monthly income is $5,000 and your bills, groceries, subscriptions, savings, transportation, and other expenses total $4,100, the calculator would estimate that you may have $900 left over for the month.
If you do not have subscriptions, savings goals, transportation costs, or other extra expenses, you can leave those sections empty. Empty optional sections count as $0.
What to Include in Your Monthly Budget
Income
Enter your estimated monthly take-home income or the income amount you want to compare against your expenses.
Bills
Include regular bills such as rent, mortgage, utilities, phone, insurance, car payments, loan payments, and other fixed costs.
Optional Expenses
Add groceries, subscriptions, savings, transportation, and other expenses only if you want them included in your estimate.
Savings
If you are setting money aside, you can add savings as an optional planned monthly amount.
How to Use the Budget Results
The result shows an estimated total for each expense category, your total monthly expenses, and your estimated leftover money. A positive leftover amount means the income entered is higher than the expenses entered. A negative leftover amount means the expenses entered are higher than the income entered.
This calculator is for general planning only. Actual monthly results may vary because of bills that change, late fees, taxes, interest, unexpected expenses, income changes, or other real-world factors.
