50/30/20 Calculator
This 50/30/20 budget calculator splits your take-home pay into 50% needs, 30% wants, and 20% savings. Enter the pay you actually receive, not your gross salary.
Already after tax. Use the take-home pay calculator if you only know your gross salary.
A worked 50/30/20 budget
On $5,000 of monthly take-home pay, this 50/30/20 calculator assigns $2,500 to needs, $1,500 to wants, and $1,000 to savings. Those are monthly ceilings. They are not a list of bills, and they do not change because a category feels fixed.
| Monthly take-home | Needs (50%) | Wants (30%) | Savings (20%) |
|---|---|---|---|
| $3,000 | $1,500 | $900 | $600 |
| $4,000 | $2,000 | $1,200 | $800 |
| $5,000 | $2,500 | $1,500 | $1,000 |
| $6,500 | $3,250 | $1,950 | $1,300 |
| $8,000 | $4,000 | $2,400 | $1,600 |
How to use the result
Start with the last three months of pay that actually hit your account, then average them.
Put rent or the mortgage, utilities, groceries, insurance, childcare you need in order to work, transportation to work, and minimum loan payments inside the needs number. Restaurants, subscriptions, hobbies, vacations, and upgrades go in wants. The savings number covers the emergency fund, retirement, and every debt payment above the minimum.
If you are paid every two weeks, there are 26 paychecks in a year, not 24. Enter one paycheck and choose “Every 2 weeks” so the monthly budget is not short by two checks.
What this calculator does not do
It does not estimate taxes. A flat tax guess is wrong for most households, so the input is take-home pay. It also does not know your city, your rent, or which purchases are needs for your household. In a high-cost area, housing alone can pass 50%. The useful next step is to name the dollars that do not fit, not to force the percentages.
Irregular income works if you average several months. A single large check will overstate every category.
Common questions
Should a 50/30/20 calculator use gross income or take-home pay?
Use take-home pay, the amount deposited after taxes and payroll deductions. The 50/30/20 rule was designed for after-tax income. Running it on gross pay makes every category look larger than the cash you can actually spend.
Where do debt payments belong in a 50/30/20 budget?
Minimum debt payments are needs. Any payment above the minimum belongs in the 20% savings category, alongside the emergency fund and retirement contributions.
What if my needs are already more than 50%?
The split is a target, not a verdict. Housing is usually the reason needs run over. Keep the 20% savings contribution if you can, and treat the gap as a specific problem to reduce rather than a reason to abandon the budget.
Is a 50/30/20 budget the same as a zero-based budget?
No. A 50/30/20 budget sets three ceilings. A zero-based budget assigns every dollar to a specific category until income minus assignments equals zero. The three ceilings are a useful starting point for those category limits.
