The 50/30/20 rule (popularised by Senator Elizabeth Warren) splits after-tax income into 50% needs, 30% wants and 20% savings and debt repayment — a simple starting framework, not a strict rule. High-cost-of-living areas often can’t hit 50% needs; adjust the split to your situation and prioritise an emergency fund and any high-interest debt.

How the 50/30/20 budget calculator works
The 50/30/20 rule is a simple budgeting framework: of your after-tax income, put 50% toward needs (essentials you can't skip), 30% toward wants (lifestyle and discretionary spending) and 20% toward savings and extra debt repayment. The tool splits your take-home pay across the three buckets and shows what belongs in each.
It's a starting framework, not a strict rule — high housing costs make hitting 50% needs hard in expensive areas, and if you have high-interest debt or no emergency fund, weighting more toward the savings bucket makes sense. Adjust the proportions to your situation. Popularised by Senator Elizabeth Warren. Educational information, not financial advice.
Frequently asked questions
What is the 50/30/20 rule?
A budgeting guideline that splits after-tax income into 50% needs, 30% wants and 20% savings and debt repayment. It's an easy framework for balancing essentials, lifestyle and financial goals without tracking every category.
What counts as a "need" versus a "want"?
Needs are essentials you can't easily go without: housing, utilities, groceries, insurance, transport and minimum debt payments. Wants are discretionary: dining out, subscriptions, hobbies, travel and shopping. The line can blur, so judge by necessity.
Should the 20% go to savings or debt?
Both — the 20% bucket covers building an emergency fund, retirement and investing, plus any extra debt repayment beyond the minimums (which sit in "needs"). If you have high-interest debt, prioritise it within this bucket.
What if I can't stick to 50% for needs?
That's common in high-cost areas. Treat 50/30/20 as a target to move toward, not a pass/fail — trimming wants, boosting income, or temporarily accepting a higher needs share are all valid. The framework is meant to be adapted.
Is take-home pay before or after retirement contributions?
Use your actual after-tax pay. If retirement contributions are deducted from your paycheck, you can either count them inside the 20% savings bucket or budget your post-deduction take-home — just be consistent so savings aren't double-counted.
