The 50/30/20 Budget Rule — Customized for You

Enter your after-tax income and see how the 50/30/20 rule splits your money. Adjust the percentages to fit your life.

How the math works

The 50/30/20 split comes from "All Your Worth: The Ultimate Lifetime Money Plan" (2005) by Elizabeth Warren and Amelia Warren Tyagi — it's a heuristic, not a government or regulatory guideline. 50% of after-tax income goes to needs (housing, groceries, utilities, minimum debt payments, necessary transportation), 30% to wants (dining out, entertainment, subscriptions), and 20% to savings and extra debt paydown beyond minimums.

The simplicity is the point: three round-number categories are easy to track without detailed line-item budgeting, which is exactly why the framework has stuck around for two decades.

Where this doesn't apply

  • High-cost-of-living areas — housing alone can push "needs" well above 50% for many households; treat that as diagnostic, not a personal failure.
  • Variable or irregular income (freelance, commission) needs an income-smoothing framework, not a fixed monthly percentage split.
  • Very high earners often find 20% savings understates real capacity — consider an absolute dollar target instead.
