How to Make a Budget: The 50/30/20 Rule Explained
A budget is simply a plan for your money before the month starts. The 50/30/20 rule is one of the easiest ways to build one because it uses just three buckets. Here is how it works, with a real example you can copy into the [Budget Calculator](/calculators/budget-calculator).

What the 50/30/20 rule is
The 50/30/20 rule divides your take-home pay — what lands in your bank account after taxes — into three groups:
- 50% Needs: things you must pay to live and work, like rent or mortgage, utilities, groceries, insurance, transportation and minimum debt payments.
- 30% Wants: things you enjoy but could cut, like dining out, streaming, hobbies, travel and shopping.
- 20% Savings and debt: emergency fund, retirement, investing and any debt payments above the minimum.
Needs = Take-home × 0.50 Wants = Take-home × 0.30 Savings = Take-home × 0.20

Worked example: $4,000 a month take-home
Worked example
Splitting $4,000 with 50/30/20
- Needs: $4,000 × 50% = $2,000
- Wants: $4,000 × 30% = $1,200
- Savings and extra debt payments: $4,000 × 20% = $800
- Check: $2,000 + $1,200 + $800 = $4,000
Over a year, the 20% bucket adds up to $9,600 for savings and debt payoff.
Sample budget split table
| Bucket | Share | Monthly amount | Example spending |
|---|---|---|---|
| Needs | 50% | $2,000 | Rent $1,300 · Utilities $150 · Groceries $350 · Car and gas $200 |
| Wants | 30% | $1,200 | Dining out $300 · Subscriptions $50 · Shopping $350 · Fun and travel $500 |
| Savings & debt | 20% | $800 | Emergency fund $300 · 401(k) or IRA $300 · Extra card payment $200 |
| Total | 100% | $4,000 |
How to make your budget in 5 steps
- Find your monthly take-home pay. If your income varies, use a low, typical month.
- List your fixed needs first: housing, utilities, insurance, minimum loan payments.
- Add up your wants from the last two or three months of bank and card statements.
- Set your savings amount and move it automatically on payday so you don't spend it.
- Compare your real numbers to 50/30/20 in the Budget Calculator and adjust.
When to change the split
High rent or cost of living
If needs take 60% or more, try 60/20/20 or 60/30/10 for now, and look for ways to lower big costs like housing or car payments.
Paying off high-interest debt
Moving money from wants into the 20% bucket speeds up payoff. Compare strategies in Debt Snowball vs Avalanche.
No emergency fund yet
Put most of the 20% into an emergency fund first. Find a target with the Emergency Fund Calculator.
The 50/30/20 rule is a guideline, not a rule you must follow exactly. The best budget is one you actually stick to.
