The 50/30/20 rule is a simple budgeting framework popularized by Senator Elizabeth Warren in her book "All Your Worth." Instead of tracking every dollar, you divide your after-tax income into three broad categories:
- 50% for Needs — Essential expenses required to live and work
- 30% for Wants — Discretionary spending that makes life enjoyable
- 20% for Savings & Debt — Building your financial future
Step-by-Step: How to Set Up Your 50/30/20 Budget
Step 1: Calculate Your After-Tax Income
Start with your take-home pay — what hits your bank account after taxes, but before pre-tax deductions like 401(k) contributions. If your income varies, use an average of the last 3-6 months.
Example: $60,000 salary ÷ 12 months = $5,000/month gross
After taxes (est. 22%): ~$3,900/month take-home
Step 2: Identify Your Needs (50%)
Needs are expenses you must pay to survive and maintain employment. If you lost your job tomorrow, these would still be required.
Common needs include:
- Rent or mortgage
- Utilities (electricity, water, gas, trash)
- Basic groceries (not dining out)
- Health insurance and prescriptions
- Minimum debt payments (credit cards, student loans)
- Transportation (car payment, gas, public transit)
- Phone (basic plan)
- Childcare (if required for work)
NOT needs: Netflix, dining out, gym memberships, shopping, subscriptions you could cancel.
50% of $3,900 = $1,950 for needs
Step 3: Budget for Wants (30%)
Wants are non-essential expenses that make life more enjoyable. These are flexible and can be reduced if needed.
Common wants include:
- Dining out and takeout
- Entertainment (movies, concerts, gaming)
- Streaming subscriptions (Netflix, Spotify, Disney+)
- Hobbies and recreation
- Gym memberships
- Shopping for non-essentials
- Vacations and travel
- Upgraded phone plans or devices
30% of $3,900 = $1,170 for wants
Step 4: Prioritize Savings & Debt (20%)
This bucket builds your future. It's not optional — it's how you create financial security.
What goes here:
- Emergency fund contributions
- Retirement accounts (401k, IRA, Roth IRA)
- Extra debt payments (above minimums)
- Investing (index funds, stocks)
- Saving for goals (down payment, car, wedding)
Note: Minimum debt payments go in "Needs." Extra payments go in "Savings & Debt."
20% of $3,900 = $780 for savings & debt

What If My Numbers Don't Fit?
Reality check: 50/30/20 is a starting point, not a strict rule. Many people can't hit these exact percentages, especially in high cost-of-living areas.
Common Adjustments
| Situation | Suggested Adjustment |
|---|---|
| High rent city (SF, NYC) | Needs 60%, Wants 20%, Savings 20% |
| Low income | Needs 70%, Wants 20%, Savings 10% (focus on income growth) |
| Aggressive debt payoff | Needs 50%, Wants 15%, Savings 35% |
| High earner | Needs 40%, Wants 20%, Savings 40% |
Pros and Cons
Pros ✅
- Simple to understand and implement
- Flexible framework, not rigid categories
- Automatically prioritizes savings
- Works as a starting point for most incomes
- Easy to explain and stick to
Cons ❌
- May not work for very low or very high incomes
- Doesn't account for cost-of-living differences
- "Needs" vs "wants" can be subjective
- Not detailed enough for complex financial situations
- 20% savings may not be enough for early retirement goals
Tips to Make It Work
- Track your actual spending first — Before changing anything, see where your money currently goes
- Adjust gradually — Don't overhaul everything at once. Change one category per month
- Automate savings — Set up automatic transfers so the 20% happens without thinking
- Review monthly — Compare actual vs planned spending and adjust
- Be honest about wants vs needs — That $15 cocktail? Definitely a want
Frequently Asked Questions
What if I live in an expensive city?
Your needs might be 60-70%. That's okay. Reduce wants accordingly, try to keep savings at 20%, but if you can't, 10-15% is still better than 0%.
Does this work for irregular income?
Yes, but calculate based on your average monthly income over 3-6 months. In high months, save the extra. In low months, draw from savings or cut wants.
Should I include my partner's income?
If you share finances, yes. Calculate the combined take-home and split accordingly. If finances are separate, each person does their own.
What about unexpected expenses?
That's what the emergency fund is for (part of the 20%). Build it up to 3-6 months of expenses so you don't derail your budget when life happens.
