How to Budget a $30,000 Salary
$30,000 a year is about $2,187 a month after tax. On the 50/30/20 rule that is $1,094 for needs, $656 for wants and $437 for savings and debt.
A $30,000 salary is not a $2,500 monthly budget. After federal tax, Social Security and Medicare, a single filer in a state with no income tax keeps about $2,187 a month — 13% of the headline number goes before you see it. Budget the $2,187, because that is the money that actually arrives.
The 50/30/20 rule splits that take-home three ways: half for the things you must pay, 30% for the things you choose, and 20% for the future. On $2,187 that comes to $1,094, $656 and $437 a month. Below, that is broken into every category and loaded into the calculator so you can move the numbers to fit your actual rent — the rule is a starting point, not a verdict.

Splitting this with someone?
Divide the shared expenses by income, or down the middle — and see what each of you is left with.
| Person | Pays | Share | Left over |
|---|---|---|---|
| Person 1 | $5,000 | 100% | $0 |
| Person 2 | $0 | 0% | $0 |
Splitting down the middle instead would move $2,500 a month between you.
Neither split is the correct one. Proportional keeps the burden equal relative to what each person earns; down the middle keeps the amounts equal. The "left over" column is usually what settles it.

Frequently Asked Questions
- About $2,187 a month for a single filer in a state with no income tax, taking the standard deduction and contributing nothing to a 401(k). A state income tax takes roughly another 3–6%, and every dollar into a traditional 401(k) lowers the tax but also the cash in hand. The Paycheck Calculator handles both.
- Half of take-home pay for needs — housing, food, transport, utilities, insurance, minimum debt payments. 30% for wants, which is everything you would drop in a bad month. 20% for savings, investing and paying debt down faster. It is popular because it is coarse: three numbers to check against, instead of forty categories nobody maintains.
- It depends almost entirely on rent. The 50% bucket has to cover housing, food, transport, utilities and insurance together, so a $547 housing budget is what makes the rest work. In an expensive city that is the binding constraint, and the honest fix is to borrow from the wants bucket rather than from savings — the rule is a target, and the savings line is the one worth defending.
- Then the numbers are telling you something the rule cannot. Look at the three largest categories first: housing, transport and food are where almost all recoverable money is, and small categories rarely add up to a fix. If needs alone exceed take-home, the problem is structural — a cheaper housing or transport decision — and no amount of trimming the wants bucket will close it.
- Net, always. Budgeting the gross salary builds a plan around money that was withheld before payday, and the gap is large: on $30,000 it is $3,759 a year. The one exception is retirement contributions taken from gross pay — those are real savings, so count them towards the 20% even though they never reach your account.
