Free Monthly Budget Calculator (50/30/20 Rule)

How it works

Enter your monthly take-home pay below. The calculator splits it using the popular 50/30/20 rule:

• 50% — Needs: rent, bills, groceries, transport
• 30% — Wants: dining out, hobbies, subscriptions
• 20% — Savings: emergency fund, debt payoff, investing

Why the 50/30/20 rule works for beginners

It’s simple enough to remember and flexible enough to adjust. If your rent alone eats 50% of your income (common in big US and UK cities), treat the percentages as targets, not laws — the real win is spending less than you earn and automating the savings part.
