What the 50/30/20 rule is

The 50/30/20 rule is a simple way to split your monthly take-home pay (what lands in your bank account after taxes) into three buckets: 50% for needs, 30% for wants, and 20% for savings. Needs are the bills you can't skip β€” rent or mortgage, groceries, utilities, insurance, transportation, and minimum debt payments. Wants are everything that makes life fun but optional: dining out, streaming, hobbies, and travel. The savings bucket covers your emergency fund, retirement contributions, and any debt payments beyond the minimums.

Why it works

Detailed line-item budgets fail because they take too much upkeep. Three buckets are easy to remember and easy to check. On $4,500 of monthly take-home pay, the rule gives you $2,250 for needs, $1,350 for wants, and $900 for savings. If your needs eat more than half your income β€” common in high-rent cities β€” treat the targets as a direction to move toward, not a pass/fail test. Everything runs in your browser; your numbers never leave your device.

How to use it

  1. Enter your monthly take-home income β€” your pay after taxes and deductions, not your gross salary.
  2. Read your three targets, which update instantly as you type.
  3. Optionally enter what you actually spent last month on needs, wants, and savings to see whether you're over or under each target.
  4. Check the fourth card for unallocated income β€” money you haven't assigned a job yet.

These figures are estimates for planning only, not financial, tax, insurance, or legal advice.

FAQ

Should I use gross or take-home pay?
Take-home (net) pay. The rule is designed around the money you can actually spend, so use your paycheck amount after taxes, health insurance, and 401(k) deductions. If you contribute to a 401(k) at work, you can count that toward your 20% savings bucket.
Do minimum debt payments count as needs or savings?
Minimum payments are needs β€” skipping them has real consequences. Anything you pay above the minimum counts toward the 20% savings bucket, since it builds your net worth.
What if my needs are more than 50%?
That's very common. Use the gap the tool shows as a signal: trim wants first, then look at bigger levers like housing, car costs, or income. Even 45/35/20 or 60/25/15 beats no plan at all.
Is 20% savings enough?
It's a solid baseline. If you're behind on retirement or building an emergency fund from zero, aim higher when you can β€” the rule is a floor, not a ceiling.
