So what is this thing? #
The 50/30/20 rule splits your after-tax income into three buckets:

100%] --> B[NEEDS
50%]
A --> C[WANTS
30%]
A --> D[SAVINGS
20%]
B --> E[Housing, Utilities
Groceries, Transport]
C --> F[Dining, Entertainment
Shopping, Travel]
D --> G[Emergency Fund
Retirement, Investments]

That’s it. Three categories. One formula.
You’re not tracking every coffee purchase. You’re not feeling guilty about buying that book. You’re just making sure your money flows into the right places.
This uses your after-tax income - the money that actually hits your account, not what you see on paper before taxes get taken out.
Breaking down the buckets #
The 50%: Needs (stuff you actually need) #
These are your essentials. The the stuff you need to survive and function:
| Category | Examples |
|---|---|
| Housing | Rent or mortgage, property taxes, home insurance |
| Utilities | Electricity, water, internet |
| Groceries | Food you cook at home |
| Transportation | Car payments, gas, insurance, public transit |
| Healthcare | Insurance, prescriptions, basic medical care |
| Minimum Debt | The absolute minimum you have to pay |
Key word: minimum. You’re not paying extra on loans here - that goes in the 20% bucket.
If your needs eat up more than 50%? You’ve got two options: make more money or spend less. Maybe that means getting a roommate. Moving somewhere cheaper. Downsizing your car.
Doesn’t sound like fun but it keeps you stable.
The 30%: Wants #
Everything that isn’t essential but makes life enjoyable:
| Category | Examples |
|---|---|
| Dining Out | Restaurants, takeout, etc. |
| Entertainment | Movies, concerts, hobbies. |
| Shopping | New clothes (beyond basics), gadgets, home stuff, accessories |
| Travel | Vacations, weekend trips, experiences, staycations. |
| Personal Care | Gym (You don’t need a gym for keeping yourself fit) , subscriptions, grooming |
You don’t need to justify every purchase. As long as you’re in this 30%, you’re fine. Enjoy it.
The trap? Convincing yourself wants are needs.
Membership? Want. The $250 sneakers? Want. New phone every year? Definitely a want.
Be honest with yourself.
The 20%: Savings & debts #
This bucket sets you free. It’s your escape plan, safety net, and ticket to financial independence.
| Category | What Goes In |
|---|---|
| Emergency Fund | 3-6 months of expenses in a savings account |
| Retirement | Whatever tax-advantaged accounts your country offers |
| Debt Payoff | Anything beyond minimum payments |
| Investments | Stocks, bonds, index funds |
| Big Purchases | Down payment for a house, car replacement fund |
Not hitting 20% yet? Start where you can. Even 10% or 15% beats nothing.
Make it automatic. Set up direct deposit so money goes to savings before you see it. Out of sight, out of mind.
Why this actually works #
It’s simple #
You’re not tracking multiple categories. You’re not logging every transaction. You’re dividing your income into three piles.
That’s it. Keep it simple. And simple means you’ll stick with it.
It’s flexible #
Your life doesn’t fit a one-size-fits-all budget.
| Your Situation | Adjustment |
|---|---|
| Expensive city | Housing might push the limits - that’s okay |
| Work from home | Transportation lower - shift money elsewhere |
| You have kids | Needs category will be larger |
| Aggressive saver | Flip to 50/20/30 or 40/20/40 |
You decide what counts as a need based on YOUR life.
It forces you to save #
You’re not saving “whatever’s left over” at the end of the month. Lock those 20% for savings and debts.
You’re paying yourself first.
It gives you permission to enjoy life #
The 30% bucket gives you breathing room. You can enjoy life AND build wealth.
How to actually use this #
Step 1: Figure out your after-tax income #
Look at your bank account. What goes in? That’s your number.
Step 2: Do the math #
| Bucket | Formula | Example ($5000/month) |
|---|---|---|
| Needs | Income × 0.50 | $2,500 |
| Wants | Income × 0.30 | $1,500 |
| Savings | Income × 0.20 | $1000 |
Step 3: Track your spending (just for a month) #
You don’t have to do this forever. But track everything for one month.
Use a spreadsheet, an app, or pen and paper. Categorize every expense into needs, wants, or savings.
And be brutally honest. It doesn’t work otherwise.
Step 4: Adjust as needed #
Needs eating up 60% of your income? Look for cuts - cheaper phone plan, meal prep instead of takeout, downgrade the car.
Wants creeping into savings? Pull back!
Step 5: Automate everything #
Set up automatic transfers on payday:
- 20% straight to savings/investments
- Bills paid automatically
- What’s left is yours to spend
Set it and forget it.
When this rule doesn’t work #
The 50/30/20 rule is a starting point, not a law. Tweak it to fit your life. See below
| Situation | Why It Struggles | Alternative |
|---|---|---|
| High cost-of-living | Needs hit 70%+ | Try 60/20/20 or 70/10/20 |
| Drowning in debt | Need aggressive payoff | Debt avalanche/snowball first |
| Irregular income | Can’t predict monthly | Zero-based budget |
| Aggressive FIRE goals | 20% isn’t enough | 50/10/40 or higher savings |
Is this right for you? #
The best budget is the one you’ll actually follow.
If 50/30/20 feels right and you can stick with it? Perfect.
If it feels too loose? Change it. Make it 60/20/20 or 50/20/30. Whatever works.
The point is being intentional with your money.
The real magic of this rule isn’t the exact percentages. It’s the mindset shift.
It forces you to:
- Separate needs from wants
- Prioritize your future
- Still enjoy the present
You’re not depriving yourself. You’re not ignoring your goals. You’re finding balance.
The Bottom Line #
50/30/20 In a Nutshell
| Bucket | % | Purpose |
|---|---|---|
| Needs | 50% | Survival - housing, food, transport, healthcare |
| Wants | 30% | Enjoyment - spending on life |
| Savings | 20% | Freedom - your future |
