Monthly Expenses

What is Budget Calculator?

The Budget Calculator helps you build a simple monthly budget by listing your after-tax income and all your expenses. It instantly shows your remaining balance, total spending, and savings rate so you can see where your money is going each month.

How to use

  1. 1 Enter your monthly take-home income (after taxes) in the income field.
  2. 2 Review the pre-filled expense categories and update each amount to match your actual spending.
  3. 3 Click Add expense to add any categories not already listed.
  4. 4 Remove any irrelevant rows using the X button next to each expense.
  5. 5 Check the remaining balance and savings rate to see how your budget stands.

Formula

Remaining Balance = Total Income − Total Expenses Savings Rate = (Remaining Balance ÷ Total Income) × 100 Spending Rate = (Total Expenses ÷ Total Income) × 100

Example calculation

With $5,000 monthly income and $3,750 in total expenses (rent, food, transport, utilities, entertainment), the calculator shows a $1,250 remaining balance and a 25% savings rate.

Frequently asked questions

What is a good savings rate?

Financial experts commonly recommend saving at least 20% of your take-home pay. Even 10% is a solid starting point if you are paying off debt. This calculator shows your current savings rate so you can track progress.

Should I use gross or net income?

Use your net (after-tax) income — the amount that actually lands in your bank account. Gross income before taxes would make your budget look larger than it really is.

What is the 50/30/20 budgeting rule?

The 50/30/20 rule suggests spending 50% of net income on needs, 30% on wants, and saving or paying down debt with the remaining 20%. This calculator helps you see how your spending aligns with that framework.

What if my expenses exceed my income?

The remaining balance will turn negative and display as over budget. This is a clear signal to reduce discretionary spending or find ways to increase income.

Can I save this budget?

The calculator runs entirely in your browser and does not save data between sessions. Copy your numbers to a spreadsheet or take a screenshot to keep a record.
