About BudgetCalculator.lat
BudgetCalculator.lat is a free tool that helps anyone plan a monthly budget in under a minute — no signup, no spreadsheet, no financial jargon.
Why we built it
Most people know they should budget, but existing tools are either overwhelming, locked behind subscriptions, or ask you to hand over bank logins. We wanted the opposite: something you can open, fill in, and understand instantly — while keeping your numbers completely private.
How it works
You enter your monthly income sources and expenses. The calculator instantly shows:
- What's left over — income minus expenses, at a glance.
- How much of your income you spend — a visual gauge so you can spot when things get tight.
- The 50/30/20 breakdown — a simple, widely recommended guideline that suggests spending about 50% of after-tax income on needs, 30% on wants, and 20% on savings and debt repayment.
Your privacy comes first
Everything is calculated in your browser. Your income and expense figures never touch our servers — they're saved only on your own device. Read the full Privacy Policy.
How it stays free
The site is supported by unobtrusive ads. That lets us keep the calculator 100% free for everyone, forever.
A note on financial advice
BudgetCalculator.lat is an educational tool, not a licensed financial advisor. The results are informational and shouldn't replace advice from a qualified professional for your specific situation.
