How the calculator works
It multiplies your take-home pay by each percentage. With the standard split and $3,000 a month, that is $1,500 for needs, $900 for wants and $600 for savings and extra debt payments. Weekly amounts are the monthly figure × 12 ÷ 52.
If you enter what your needs cost today, the calculator shows them as a share of your pay and tells you whether they fit the split you picked.
What goes where
- Needs: rent or housing, utilities, basic groceries, transport to work, insurance, minimum loan payments, regular family support people depend on.
- Wants: eating out, delivery, subscriptions, hobbies, travel, upgrades.
- Savings: emergency fund, savings goals, retirement savings you make yourself, payments above the minimum on debt.
Choosing a split
50/30/20 is a starting point, not a law. If rent takes more than half your pay, try 60/20/20. If you support family, 70/20/10 may be realistic. If you are paying off expensive debt or saving for something soon, 50/20/30 moves money from wants to your future. Whatever you choose, move the savings part on payday.
Questions
Should I use gross or net pay?
Net, take-home pay: what actually reaches your account after tax and deductions.
My needs are above 50%. Am I doing it wrong?
Not necessarily. In many cities housing alone is close to half of take-home pay. Pick a split with a bigger needs share and protect savings first.
Where do debt payments go?
Minimum payments are needs. Anything above the minimum counts as savings, because it improves your future position.
Is my income stored?
No. The calculator runs in your browser only.
