What's in it

Instant targets

Your three numbers, computed from take-home pay. No percentages to fiddle with.

Target vs actual

The column that matters: where your real spending sits against the rule, per bucket.

Honest fine print

The sheet says what the rule's fans won't: if needs alone eat 60-70%, that's a cost-of-living reality, not a personal failure.

How to use it

  1. Download the file: the button above grabs the .xlsx.
  2. Google Sheets: drive.google.com → New → File upload → open it → File → Save as Google Sheets. Excel: just open it.
  3. Enter monthly take-home pay: what actually hits your account.
  4. Fill in your actuals for needs, wants, and savings/debt (estimates are fine).
  5. Read the difference column. Positive = under target, negative = over. Now you know which lever to look at.
  6. The one rule: shaded cells are yours to type in. Everything else computes itself.

Questions

Where does 50/30/20 come from?

Senator Elizabeth Warren and Amelia Warren Tyagi popularized it in "All Your Worth" (2005) as a sanity check, not a law. Our guide covers when it works and when it honestly doesn't.

My needs are way over 50%. Broken?

No. High rent or low income breaks the ratio for millions of people. The useful move is switching from percentage targets to paycheck-timing: making sure each check covers its own bills. That's what our paycheck method does.

Is a minimum debt payment a need or the 20%?

Minimums are needs (they keep you current). Extra payments beyond minimums count toward the 20%.

Percentages diagnose. Paychecks fix.

The 50/30/20 rule tells you roughly where you stand. The Payday System tells you what this week's check needs to do. $29 once.
