Basis
After-Tax Income
The 50/30/20 rule divides after-tax income into three buckets: 50% for needs, 30% for wants, and 20% for savings and debt repayment. Popularized by Elizabeth Warren and Amelia Warren Tyagi in All Your Worth (2005), it provides structure without requiring line-item expense tracking.
Example at Median Income
Based on U.S. median after-tax household income of ~$72,330/year ($6,028/month):
| Category | Allocation | Monthly | Annual |
|---|---|---|---|
| Needs | 50% | $3,014 | $36,165 |
| Wants | 30% | $1,808 | $21,699 |
| Savings | 20% | $1,206 | $14,466 |
Common Variations
The 50/30/20 split is a starting point. These variations adjust for different financial situations:
| Situation | Needs | Wants | Savings |
|---|---|---|---|
| Standard | 50% | 30% | 20% |
| High cost-of-living | 60% | 20% | 20% |
| Aggressive debt payoff | 50% | 20% | 30% |
| FIRE (early retirement) | 30% | 20% | 50% |
| Low income / starting out | 70% | 20% | 10% |
Use after-tax income: Calculate from your take-home pay — what lands in your bank account after all taxes. Pre-tax 401(k) and health insurance deductions count toward “Savings” and “Needs” respectively.
50% Needs
Needs are essential expenses required for survival and basic functioning — things you must pay to live and work. The goal is to keep these at or below 50% of after-tax income.
| Category | Examples | Typical % of Income |
|---|---|---|
| Housing | Rent/mortgage, property taxes, homeowner’s/renter’s insurance | 25–35% |
| Utilities | Electric, gas, water, basic internet, phone | 5–10% |
| Groceries | Basic food and household supplies (not dining out) | 5–15% |
| Transportation | Car payment, insurance, gas, public transit | 5–15% |
| Insurance | Health, life, disability premiums | 5–10% |
| Minimum debt payments | Minimum payments on credit cards, student loans | Varies |
| Childcare | Daycare, after-school care required for work | Varies |
Housing Cost Reality
Housing alone often makes the 50% target challenging. More than half of all renters are “cost-burdened” (spending more than 30% of income on housing).
| Housing Situation | Median % of Income | % Cost-Burdened |
|---|---|---|
| Renters | 31.0% | 50.3% |
| Homeowners (with mortgage) | 21.4% | 24.3% |
| Homeowners (no mortgage) | 11.5% | ~15% |

High-cost areas: In cities like Miami, San Francisco, or New York, housing alone may consume most of the 50% allocation. See the Common Variations table in the overview for adjusted splits.
30% Wants
Wants are non-essential expenses that enhance quality of life but aren’t required for survival. The 30% allocation provides room for enjoyment — the key is intentionality about what genuinely adds value.
| Category | Examples |
|---|---|
| Dining & drinks | Restaurants, coffee shops, bars, takeout, food delivery |
| Entertainment | Streaming services, concerts, movies, sports tickets, hobbies |
| Shopping | Clothing beyond basics, electronics, home décor, gadgets |
| Travel & vacations | Flights, hotels, vacation rentals, weekend getaways |
| Personal care | Salon visits, spa treatments, premium skincare |
| Memberships | Premium gym, clubs, subscription boxes |
| Upgrades | Nicer car than needed, premium phone plan, faster internet tier |
Sample Wants Budget ($1,800/mo)
One way to allocate 30% of median after-tax income (~$1,800/month):
| Category | Monthly | % of Wants |
|---|---|---|
| Dining out & coffee | $400 | 22% |
| Entertainment & subscriptions | $200 | 11% |
| Shopping & clothing | $300 | 17% |
| Vacation savings | $400 | 22% |
| Hobbies & fitness | $250 | 14% |
| Personal care & grooming | $150 | 8% |
| Flex / buffer | $100 | 6% |
Need vs. want test: Ask “Can I survive without this?” If yes, it’s a want. Basic groceries are a need; organic premium brands are partly a want. A reliable commute car is a need; a luxury upgrade is a want.
20% Savings
The 20% savings allocation covers emergency funds, retirement contributions, extra debt payments beyond minimums, and major goal savings. A common approach is to prioritize in the order shown below.
| Priority | Category | Details |
|---|---|---|
| 1 | Starter emergency fund | $1,000–$2,000 for immediate emergencies |
| 2 | Employer 401(k) match | Contribute enough to capture the full match |
| 3 | High-interest debt | Extra payments on balances above ~7% APR |
| 4 | Full emergency fund | Build to 3–6 months of expenses in HYSA |
| 5 | Max tax-advantaged accounts | IRA ($7,000/$8,000 catch-up), HSA, additional 401(k) |
| 6 | Goal savings & taxable investing | Down payment, education, brokerage accounts |
Where to Keep It
Short-Term (0–5 years)
High-yield savings accounts (4–5% APY), money market accounts, CDs for fixed timelines, Treasury bills (state tax-free).
Long-Term (5+ years)
401(k)/403(b) with employer match, Traditional or Roth IRA, HSA for healthcare, taxable brokerage after maxing tax-advantaged accounts.
Automate first: Set up automatic transfers on payday so savings happens before you see the money. If 20% isn’t feasible now, start at 5% and increase by 1% every few months — consistency matters more than the exact percentage.
