Budget Calculator

The 50/30/20 budget rule is a simple framework for managing your money. Proposed by Senator Elizabeth Warren, it divides your after-tax income into three categories: 50% for needs (housing, food, utilities, minimum debt payments), 30% for wants (dining out, entertainment, hobbies), and 20% for savings and debt repayment. This calculator shows you where you stand.

The Formula

The 50/30/20 Rule: Needs = 50% of income, Wants = 30% of income, Savings & Debt Repayment = 20% of income. If your needs exceed 50%, look for ways to reduce fixed costs or increase income. If your wants exceed 30%, identify discretionary spending to cut.

Why It Matters

You earn $5,000/month after taxes. Your fixed expenses total $2,500 (exactly 50%). Your variable expenses are $1,000 (20% of income, well under the 30% wants limit). This means you have $1,500 left — enough to save $1,000 (20%) and still spend $500 on wants. You're in a strong financial position.

Frequently Asked Questions

What if my needs exceed 50% of my income?

High-cost areas often make the 50% target unrealistic. If your needs are above 50%, shift the ratio — try 60/20/20 or 65/15/20. The key is to keep the savings target intact and reduce discretionary spending instead. Over time, look for ways to lower fixed costs: refinancing your mortgage, downsizing, or finding a cheaper housing option.

Does the 50/30/20 rule include student loan payments?

Minimum student loan payments count as needs (the 50% category). Any extra payments you make toward paying off student loans faster go into the savings/debt repayment bucket (the 20%). This distinction rewards proactive debt repayment while ensuring basic needs are covered first.

Should I use gross or net income?

Use your after-tax income (take-home pay) for the 50/30/20 rule. This is the money you actually have available to spend. If your paycheck doesn't reflect all deductions (like a 401k contribution), subtract those from your gross income first.
