Budget Calculator: 50/30/20 Rule

Enter your monthly take-home pay to see exactly how much should go toward needs, wants, and savings — using the classic 50/30/20 split, or your own custom percentages.

Total: 100% (default 50/30/20 rule)
Needs
rent, food, utilities, minimum debt payments
Wants
dining out, entertainment, subscriptions
Savings / Debt
emergency fund, extra debt payoff, investing

What typically fits in each category

Needs: rent or mortgage, utilities, groceries, insurance, minimum debt payments, transportation to work.

Wants: dining out, streaming subscriptions, hobbies, travel, non-essential shopping.

Savings/Debt: emergency fund contributions, retirement savings, extra (above-minimum) debt payments.

Percentages are automatically scaled to add up to 100% of your income, even if your entered percentages don't total exactly 100. This is a general framework, not a rule that fits every situation — high cost-of-living areas, for example, often need a larger "needs" share. Not financial advice.

How the 50/30/20 Rule Works

The 50/30/20 rule splits your after-tax income into three buckets: 50% needs (the bills you can't skip), 30% wants (the spending that makes life enjoyable), and 20% savings and debt payoff (building your future and reducing what you owe). It's a starting framework, not a rigid law — you can adjust the percentages above to fit your own situation, whether that's a higher needs share in an expensive city or a bigger savings push while you're debt-free and motivated.
