50/30/20 Rule

From *All Your Worth* (Warren & Tyagi, 2005). A single rule of thumb that makes allocation decisions tractable without spreadsheet overhead.

**The three buckets:**

• **50% to NEEDS** — rent/mortgage, utilities, groceries, insurance premiums, minimum debt payments, transport, healthcare, childcare. Things you couldn't eliminate without changing your life.
• **30% to WANTS** — restaurants, streaming, travel, hobbies, non-essential clothing, gifts. Discretionary by definition.
• **20% to SAVINGS + DEBT** — emergency fund, 401(k) above match, Roth IRA, taxable brokerage, HSA, **plus above-minimum debt paydown** (credit cards, student loans beyond minimum).

**Percentages are on after-tax / take-home income**, not gross. So someone with $70k gross / ~$55k take-home works with: $2,292 needs + $1,375 wants + $917 savings per month.

**When 50/30/20 works well:**

• First-time budgeter wanting a simple frame.
• Moderate cost-of-living area + moderate lifestyle.
• Income high enough that 50% actually covers needs (below ~$50k gross in a high-COL area, needs will blow past 50% regardless).

**When 50/30/20 breaks:**

• **High-COL area** (NYC / SF / Boston / DC): rent alone eats 35–40%, "needs" hit 60–70%. Modify to 70/20/10 or accept the needs overage and compensate by trimming wants.
• **Aggressive savers / FIRE**: inverts to 50/20/30 or 40/10/50.
• **Debt emergency** (Ramsey Baby Step 2 territory): temporarily 50/20/30 with the extra 10 going to debt avalanche.

**Compared to alternatives on this page:**

• **vs. Profit First Personal** — Profit First uses multi-account routing (separate bank buckets). 50/30/20 can run in a single account with light tracking. Profit First is stronger for irregular 1099 income.
• **vs. YNAB (zero-based)** — YNAB demands every dollar have a job. 50/30/20 is coarser. YNAB wins on tracking granularity; 50/30/20 wins on cognitive load.
• **vs. Ramsey Baby Steps** — Baby Steps are sequenced (debt first, then emergency fund, then retirement). 50/30/20 is concurrent (save + spend + pay debt in parallel).

**The honest simplification:** for most Americans whose problem is "I don't know where my money goes," 50/30/20 is the smallest intervention that produces discipline. After 6 months of running it, the user has enough self-knowledge to graduate to a more tailored framework.
