Frequently Asked Questions

What is the 50/30/20 rule?
The 50/30/20 rule is a simple budgeting framework popularized by Senator Elizabeth Warren: spend 50% of after-tax income on needs (housing, utilities, groceries, transport), 30% on wants (dining, entertainment, subscriptions), and put 20% toward savings and extra debt repayment. It's a starting guideline, not a law — many households adjust the ratios to fit their cost of living.
How do I calculate my 50/30/20 budget?
Take your monthly after-tax take-home pay and multiply by 0.50 for needs, 0.30 for wants, and 0.20 for savings. For example, on $4,000 a month: $2,000 for needs, $1,200 for wants, and $800 for savings. This calculator does that split instantly and lets you enter your actual spending to compare against it.
Is my financial data uploaded anywhere?
No. The entire calculation runs in your browser with plain JavaScript. Your income, spending, and budget are never uploaded, stored on a server, or transmitted anywhere. The calculator works offline after the page loads, and your entries auto-save locally so you don't lose them between visits.
What counts as a need vs. a want?
Needs are the essentials required to live and work: housing, utilities, groceries, transportation, insurance, and minimum debt payments. Wants are everything optional: dining out, entertainment, hobbies, subscriptions, and upgrades. When in doubt, ask whether you could live without it this month — if yes, it's a want.
What if my needs cost more than 50% of my income?
You're not alone — in high-cost areas, needs often run 60-70% of income. The calculator lets you adjust the ratios (try 60/20/20 or 70/20/10) to see a realistic target, then look for ways to trim the biggest need (housing is usually the lever). The goal is a plan you can actually stick to, not a perfect ratio.
Does the 20% savings include debt payments?
Yes. The 20% bucket is for building your financial future, which includes an emergency fund, retirement contributions, and any debt payments above the minimum. Minimum debt payments belong in the needs bucket since they're obligations — the extra payments are what count as savings.
