The Budget Calculator shows where your money goes each month and what is left over. Enter your take home pay and your spending across housing, food, transport, utilities, entertainment and other costs, and the tool calculates your total expenses, monthly leftover, savings rate and yearly leftover in one click.

Whether you are building your first budget or tightening an existing one, the calculator turns guesswork into clear numbers. It is free and needs no signup.

Frequently Asked Questions (FAQ)
Is the Budget Calculator free? Yes. It is completely free with no signup.
Should I use gross or take home pay? Use take home pay, the amount that actually lands in your account after taxes. That is the money you can spend and save.
What is a good savings rate? The 50/30/20 rule suggests 20 percent. Any positive rate is a start, and higher is better if your essentials allow it.
What if my expenses exceed my income? The calculator will show a negative leftover. That is your signal to trim wants first, then look for cheaper options on the biggest need categories.
Do I need an account? No. The calculator works instantly with no signup.
How often should I redo my budget? Revisit it monthly at first, then quarterly once your spending is stable. Redo it right away after any big income or rent change.
