Budget Calculator
Organize income and monthly expenses to see what's left over and where your money actually goes.
How this calculator works
- Enter your monthly income from salary, freelance work and other sources.
- Enter your monthly expenses across common categories: rent, food, transportation, utilities, insurance, entertainment and other.
- The calculator totals both sides and shows your remaining money, savings percentage, and a category breakdown chart.
This calculator totals your income sources and expense categories, then shows what's left over, your savings rate, and a visual breakdown of where your money goes each month. Nothing is saved or sent anywhere — it's a quick snapshot you can rerun any time your numbers change.
Example
With $5,000 total monthly income and $3,800 in total expenses, you have $1,200 remaining — a 24% savings rate.
Limitations
Categories here are simplified for a quick monthly snapshot — irregular or annual expenses (insurance premiums, gifts, car maintenance) may need to be averaged into a monthly figure yourself for an accurate picture.
Frequently asked questions
How is my savings percentage calculated?
Remaining money (income minus expenses) divided by total income, shown as a percentage.
What if my expenses are higher than my income?
The calculator will show a negative remaining amount in red — a signal to review categories where spending might be reduced.
Does this save my budget?
No — everything is calculated locally in your browser and nothing is stored or sent anywhere. Rerun it any time with updated numbers.
What if I have expense categories not listed here?
Add them to “other” — or use the Monthly Expense Calculator for a fully flexible, custom list of expense line items.
