About the 50/30/20 budget calculator
The 50/30/20 rule is the simplest budget there is. You split your take-home pay (after tax) into three parts:
- 50% for needs — what you must pay: rent or mortgage, utilities, groceries, insurance, transport, minimum debt payments
- 30% for wants — what makes life nice: eating out, streaming, hobbies, holidays, new clothes
- 20% for savings and debt — emergency fund, savings goals, retirement, paying off debt faster
Type your income and the calculator shows the three amounts for every month, with a chart. Enter what you spend now in each part to see where you are over or under.

- Type your income after tax and choose how often you are paid
- Pick a budget rule — 50/30/20 is the usual one

| 60 / 20 / 20 | 60% | 20% | 20% | High rent or cost of living |
| 70 / 20 / 10 | 70% | 20% | 10% | Tight budgets, starting out |
| 80 / 20 | 80% | — | 20% | "Pay yourself first": save 20%, spend the rest freely |
Is it a need or a want?
- Need: if you stopped paying, something important would break — a home, heating, food, getting to work, insurance, the minimum on a loan.
- Want: you would miss it, but life goes on — takeaway, the bigger TV package, a new phone before the old one breaks.
- Groceries are a need; eating out is a want. Basic phone plan is a need; the upgrade is a want.
Frequently asked questions
How does the 50/30/20 rule work?
You take your income after tax and spend at most 50% on needs, 30% on wants, and put at least 20% into savings or extra debt payments. With $4,000 a month: $2,000 needs, $1,200 wants, $800 savings.
Should I use my gross or net income?
Net — your take-home pay after tax. If your employer takes retirement savings straight from your pay, you can add that back and count it in the 20%.
What if my needs are more than 50%?
That is common where rent is high. Try 60/20/20 or 70/20/10, and look for the biggest need you can lower — housing, transport or insurance — over time.
Does paying off debt count as savings?
Minimum payments are a need. Anything above the minimum goes in the 20%, because it improves your money the same way saving does.
Is this financial advice?
No. It is a simple planning calculator. For your own situation — debt, investing, retirement — talk to a qualified adviser.
