Use the 50/30/20 rule to build a budget that works. Enter your monthly take-home income and see how to split it.
What is a budget calculator?
A budget calculator helps you divide your income into spending categories so you don't run out of money before the month ends. The 50/30/20 rule is one of the most popular methods — it's simple enough to remember and flexible enough to adapt to different income levels.
How to use this budget calculator
Enter your monthly after-tax (take-home) income. The calculator instantly shows:
- Needs (50%) — Your hard limit for essentials
- Wants (30%) — Guilt-free spending on things you enjoy
- Savings (20%) — What to set aside every month
Tips for sticking to your budget
- Automate savings transfers on payday — pay yourself first
- Review spending weekly, not monthly, to catch drift early
- Use a separate account for wants to make the limit physical
- Track actual vs. budgeted by category using an app like Finlingo
Frequently Asked Questions
What is the 50/30/20 rule?+
The 50/30/20 rule splits your after-tax income into needs (50%), wants (30%), and savings or debt repayment (20%). It's a simple framework that works for most income levels.
How do I calculate my monthly budget?+
Take your monthly take-home pay and multiply by 0.5 for needs, 0.3 for wants, and 0.2 for savings. Our calculator does this automatically.
Is the 50/30/20 rule realistic?+
In high cost-of-living cities, needs may consume 60-70% of income. Adjust the ratios to what works for your situation — the important thing is spending less than you earn.
What counts as a 'need' vs a 'want'?+
Needs are unavoidable: rent, utilities, groceries, minimum debt payments, insurance. Wants are everything else — dining out, streaming, gym memberships, vacations.
What if I can't save 20%?+
Start with 1-5% and increase by 1% each month. Automating savings the day after payday makes it painless.
