50/30/20 Budget Calculator
Split your monthly take-home pay into needs, wants, and savings using the 50/30/20 rule — or set your own percentages.
50% needs · 30% wants · 20% savings & debt
The 50/30/20 rule splits your monthly take-home pay into 50% needs, 30% wants, and 20% savings and debt. On $4,000 a month that is $2,000 for needs, $1,200 for wants, and $800 for savings and extra debt payments. Change the income and every share updates instantly.
What the 50/30/20 rule is
The 50/30/20 rule is a simple framework for dividing your after-tax income into three buckets. Needs are the essentials you can’t skip — housing, groceries, utilities, transport, insurance, and minimum debt payments. Wants are the lifestyle extras — dining out, streaming, hobbies, travel. Savings and debt covers building an emergency fund, investing, and paying down loans faster than the minimum. Because it works on percentages, the same split scales to any income.
Use your monthly take-home (net) pay. A custom split works the same way — just make sure the three percentages add up to 100%.
Worked example
Suppose your take-home pay is $4,000 a month.
- 1 Start from take-home pay. Use net income after tax and deductions — here $4,000 a month.
- 2 Multiply by 0.50 for needs. 4,000 × 0.50 = $2,000 for rent, food, utilities, and minimum payments.
- 3 Multiply by 0.30 for wants. 4,000 × 0.30 = $1,200 for dining out, subscriptions, and fun.
- 4 Multiply by 0.20 for savings and debt. 4,000 × 0.20 = $800 toward savings, investing, and extra debt payoff.
- 5 Check the parts add back up. 2,000 + 1,200 + 800 = $4,000, your full take-home pay.
What counts in each bucket
Borderline items depend on your situation — a car may be a need if you commute, a want if it’s a second vehicle.
| Bucket | Share | Typical items |
|---|---|---|
| Needs | 50% | Rent or mortgage, groceries, utilities, transport, insurance, minimum debt payments |
| Wants | 30% | Dining out, streaming and subscriptions, hobbies, travel, upgrades |
| Savings & debt | 20% | Emergency fund, retirement and investing, extra payments above the minimum |
Treat it as a guideline, not a rule
The 50/30/20 split is a starting point, not a law. In high-cost cities rent alone can push needs well past 50%, so you may run something closer to 60/20/20 or 70/20/10 for a while — that’s fine as long as it’s deliberate. If money is tight, trim wants before savings only as a last resort; even a small, steady 20% builds the habit and a cushion. Adjust the percentages to fit your income, goals, and stage of life.
