Does your paycheck split 50 / 30 / 20? The ledger checks.
The rule is three numbers: 50% of take-home pay for needs, 30% for wants, 20% kept. Most budgets fail it quietly — the needs line runs heavy and the 20% absorbs the difference. Post your real month below and the slip stamps which bucket is breaking the rule, by how many dollars, and what that costs you a year.
Prefilled at $5,200 take-home: needs post $300 over the line, savings $390 short — $4,680 a year. Verdict: NEEDS OVER.
The allocation ledger, Form BG-16. Top line: what actually lands in your account each month. Below it: what you currently spend on needs, on wants, and what you keep. The slip posts the 50 / 30 / 20 targets beside your real numbers and stamps which bucket is breaking the rule.
Targets are your take-home pay multiplied by 50%, 30%, and 20% — nothing fancier. The rule was popularised by Senator Elizabeth Warren's All Your Worth (2005); this slip posts it honestly, including when your city's rent makes 50% a wish rather than a plan.

How the ledger splits a paycheck
The 50/30/20 rule does one thing most budgets refuse to do: it gives savings a line of its own. Fifty percent of take-home pay for needs, thirty for wants, twenty kept — savings, investing, and debt payoff above the minimum. On the prefilled ledger, $5,200 lands each month, so the targets post at $2,600, $1,560, and $1,040. Everything this slip stamps follows from comparing your real numbers to those three multiplications.
The prefilled month is deliberately ordinary, and it fails the way most months fail. Needs post at $2,900 — 55.8% of pay, $300 over the line — because rent and transport do not care about a rule written in 2005. Wants are fine at $1,400. So the overage comes out of the only bucket with no bill collector: savings keeps $650 instead of $1,040, a $390 monthly shortfall that compounds to $4,680 a year. Nobody overspent on lattes. The needs line is heavy, and the 20% absorbed it silently, the way it does every month it is not assigned on payday.
That diagnosis is the tool's actual output. Each stamp names a different fix. NEEDS OVER means willpower is not the lever — the big fixed bills or the income line are. WANTS OVER is the fixable budget: the savings gap is sitting in the wants bucket, itemised and cuttable. SAVINGS SHORT with both spending lines inside target means nothing is wrong except assignment — the 20% needs a payday transfer, not a spending cut. And ON THE RULE means the frame is working and the only remaining job is aiming the 20% well: buffer first, expensive debt second, investing third.
Two honest limits. The rule splits take-home pay, so it says nothing about the tax line above it. And 50% needs is a 2005 national frame — in high-rent cities the same ledger stamps NEEDS OVER on careful households, which is information about the city, not the household. The adjusted split for that case is posted on the high-rent page in this set.
Disclaimer: the figures here are arithmetic, not financial advice. The 50/30/20 frame is a reference split, not a law — your rent, dependants, and debts move your version of it.

Questions from the budgeting desk
What is the 50/30/20 rule?
A budgeting frame from Elizabeth Warren's All Your Worth (2005): split after-tax income into 50% needs, 30% wants, and 20% savings and extra debt payoff. On $5,200 of monthly take-home pay that posts as $2,600 for needs, $1,560 for wants, and $1,040 kept. The point is not the exact split — it is that savings gets a line of its own instead of whatever survives the month.
What are my targets on $5,200 a month?
Needs $2,600, wants $1,560, savings $1,040. The prefilled ledger spends $2,900 on needs (55.8% — $300 over), $1,400 on wants (26.9%, inside the line), and keeps $650 (12.5% — $390 short, which is $4,680 a year). That is the commonest shape this slip sees: the budget is not reckless, the needs line is simply heavy, and the 20% quietly absorbs the difference.
Is the rule still realistic with today's rent?
In high-cost cities, often not at 50% — and the slip says so rather than pretending. When rent alone takes 35–40% of take-home pay, needs land at 60–65% no matter how frugal the rest of the month is. The working adjustment is to flip the order: hold the 20% savings line if you possibly can, let needs run over, and let wants take what is left (a 65/20/15 shape). The high-rent page in this set posts that version in full.
Does the 20% include retirement contributions?
Yes — 401(k) contributions, IRA funding, emergency-fund deposits, investing, and debt payments above the minimum all count in the 20%. A common miscount: employer retirement contributions do not come out of your take-home pay, so do not double-count them; count what your own paycheck assigns. Minimum debt payments are needs (the bill arrives regardless); everything above the minimum is the 20% attacking the balance.
What if my buckets add up to more than my pay?
Then the difference is being borrowed — from a credit card, a savings account, or next month. The slip flags that case plainly instead of stamping a polite verdict. Fix order: stop the over-assignment first (usually the wants line), then rebuild the buckets so spent plus kept equals pay, then chase the 50/30/20 shape. A balanced 60/25/15 beats an imaginary 50/30/20 funded by a card.
Is this financial advice?
No — it is arithmetic on numbers you type, with the standard 50/30/20 frame as the reference. It does not know your debts, your city, or your dependants. A fiduciary adviser who knows your whole ledger has the final word; this slip just makes sure the percentages are honest.
