Where the 30% comes from
The 30% figure is not a legal limit on rent. It is a measuring line used by federal agencies. HUD calls a household cost burdened when its monthly housing costs, including utilities, are more than 30% of its monthly income, and severely cost burdened above 50%. The Census Bureau uses the same lines when it reports on housing affordability.
The number has a long history. A report by the Congressional Research Service traces it to 19th century studies of household spending, which found that families typically spent 20% to 25% of their income on housing. That observation became a rule of thumb, and later federal policy:
- In 1969, the Brooke Amendment capped the rent families in public housing had to pay at 25% of adjusted family income.
- In 1981, a further law raised that share to 30% for all families in public housing and the Section 8 programs.
- After a 1990 law required local housing affordability strategies, HUD built its CHAS data on the same 30% standard.
So the 30% line comes from the rules for subsidized rent and is used to count households under strain. It was never a promise that 30% is comfortable for everyone, or that 31% is a problem. It is a useful first check, and a common one: in the Census Bureau's report on 2023 data, 46.3% of renter households paid more than 30% of their income for housing, and 23.9% paid more than half.
Rent at 25%, 30% and 35% of income
The basic math is short:
Here is the result at 25%, 30% and 35% for several yearly incomes. The amounts are for rent plus utilities together, the way HUD and the Census count housing costs.
| Yearly gross income | Per month | 25% | 30% | 35% |
|---|---|---|---|---|
| $30,000 | $2,500 | $625 | $750 | $875 |
| $45,000 | $3,750 | $938 | $1,125 | $1,313 |
| $60,000 | $5,000 | $1,250 | $1,500 | $1,750 |
| $75,000 | $6,250 | $1,563 | $1,875 | $2,188 |
| $100,000 | $8,333 | $2,083 | $2,500 | $2,917 |
| $150,000 | $12,500 | $3,125 | $3,750 | $4,375 |
If you are paid by the hour, turn your wage into a yearly figure first. The salary converter does that and also explains biweekly vs semimonthly paychecks.
Read the table as a range, not a verdict. Each step of 5 percentage points is a real difference in money: at $60,000 a year it is $250 a month, or $3,000 a year. Where you land inside that range depends on your other costs, which the next sections cover.
Gross pay vs take-home pay
When the Census Bureau applies HUD's cost burden definition, it divides housing costs by gross household income, the total before taxes. But rent is paid from take-home pay, after federal income tax, Social Security, Medicare, any state tax and any deductions for retirement or health insurance. That makes 30% of gross a noticeably bigger share of the money you actually receive.
The table below takes 30% of gross income and compares it with an estimate of monthly take-home pay for a single filer with no 401(k) or other deductions, using the 2026 figures from the paycheck calculator. Texas has no state income tax on wages; California has a state income tax and a state disability payroll tax.
| Yearly gross income | 30% of gross per month | Take-home per month, Texas | Share of take-home, Texas | Share of take-home, California |
|---|---|---|---|---|
| $30,000 | $750 | $2,190 | 34.2% | 35.1% |
| $45,000 | $1,125 | $3,195 | 35.2% | 36.5% |
| $60,000 | $1,500 | $4,199 | 35.7% | 37.5% |
| $75,000 | $1,875 | $5,133 | 36.5% | 38.9% |
| $100,000 | $2,500 | $6,598 | 37.9% | 41.2% |
| $150,000 | $3,750 | $9,483 | 39.5% | 44.1% |
At $30,000 a year, 30% of gross is about 34.2% of take-home pay in Texas. At $150,000, where income tax takes a bigger bite, it is 39.5% in Texas and 44.1% in California. Retirement contributions or health insurance through your paycheck push the share higher still. To see your own number, enter your pay, state and deductions in the paycheck calculator, then divide the rent you are considering by the monthly result.
Neither measure is wrong. Gross income is what the official statistics use. Take-home pay is what your budget runs on. Knowing both keeps you from being surprised when the first rent payment leaves your account.
What counts as housing cost
A listing shows the rent. The cost of living there is more than that. In the official measures, utilities are part of housing cost: the Census Bureau's gross rent is the rent plus the estimated monthly cost of electricity, gas, water and sewer and heating fuel when the renter pays them. Its stated purpose is to make a unit with utilities included comparable to one where you pay them on top.
For your own budget, a few more monthly costs come with the home even though the official figure leaves them out:
- Renters insurance. The landlord's policy covers the building, not your belongings. The NAIC, the association of state insurance regulators, says on its consumer page that an average renters policy costs $15 to $30 a month.
- Parking. A garage space or permit can be a separate monthly charge.
- Internet, if the building does not include it.
- Pet rent or other monthly fees named in the lease.
The way to use this: start from your housing budget, subtract the monthly extras, and what is left is the most you would pay in rent. The figures below are examples for a $60,000 income; your own bills will differ.
| Item | Per month |
|---|---|
| Housing budget, 30% of $60,000 a year | $1,500 |
| Minus electricity and gas (example) | −$140 |
| Minus water, sewer and trash (example) | −$60 |
| Minus internet (example) | −$65 |
| Minus renters insurance (example) | −$20 |
| Minus parking space (example) | −$75 |
| Rent that keeps the total at 30% | $1,140 |
Counting only the utilities, as the official measure does, the rent could be $1,300. Counting everything tied to the home, it is $1,140. When you compare two apartments, ask each landlord which utilities are included and what the average bills have been, and compare the totals rather than the rents. For the electricity part, the electricity cost calculator shows what heaters, air conditioners and other appliances add.
What is left after rent
A percentage of income says nothing about what remains for everything else, and that is where the 30% rule is weakest. The Congressional Research Service report notes that the ratio may understate affordability problems for lower-income households and overstate them for higher-income ones. The reason is simple. At $30,000 a year, 70% of income left after housing still has to cover food, transportation, health care and debt payments out of a small amount. At $150,000, the same 70% is far more money.
Researchers call the alternative a residual income approach: housing is affordable if what is left after housing covers a basic budget. You can do a personal version of that check:
- Take your monthly take-home pay. For the $60,000 single filer in Texas above, about $4,199.
- Subtract the full housing cost you are considering. At $1,500, about $2,699 is left.
- List everything else you pay each month: groceries, transportation, insurance, phone, debt payments, savings, and the costs that come only a few times a year, divided by 12.
- If the list does not fit into what is left, the rent is too high for you, whatever percentage it is.
The budget planner sorts that list into needs, wants and savings and shows where the money goes, so this guide does not repeat how the 50/30/20 split works. If you prefer paper or a spreadsheet, the free monthly budget spreadsheet adds up income, bills and spending for you, and the bill tracker lists due dates for rent, utilities and insurance so none slips after the move.
The cash you need before you move in
The monthly rent is one question. The other is how much cash you need on the day you sign. That can include:
- First month's rent, paid before or at move-in.
- A security deposit. It is refundable when you move out, minus allowed charges, but it has to be paid now. How much a landlord may ask for is set by state law. California, for example, limits it to one month's rent for most landlords since July 1, 2024, with up to two months allowed for some small landlords. New York limits the deposit or advance payment to one month's rent, which also means a landlord there cannot ask for the last month's rent on top of a deposit. Other states have other rules or none, so check your state attorney general's tenant guide.
- Application fees. According to the CFPB, landlords often use the fee to buy a tenant screening report. Fees are paid per application, so applying for several apartments multiplies them. State law can limit them: New York, for example, limits the charge for a credit and background check to $20.
- Moving costs: a truck or movers, boxes, and possibly utility setup fees.
Here is an example for a $1,400 apartment in a state with a one-month deposit limit. The fee and moving amounts are made up for the example.
| Up-front cost | Amount |
|---|---|
| First month's rent | $1,400 |
| Security deposit, one month's rent | $1,400 |
| Application fees, 3 applications at $40 | $120 |
| Renters insurance, first month | $20 |
| Truck rental, boxes and tape | $450 |
| Total before the first night | $3,390 |
That is about 2.4 times the monthly rent, before furniture or a gap month where you pay rent on the old and the new place at the same time. The moving checklist lays out the weeks before a move, including the moving budget, so the timing of these payments is easier to plan.
How landlords judge what you can afford
Landlords set their own criteria for which applicants they accept, and those criteria vary. Many use a tenant screening report, often paid for with the application fee. The CFPB lists what such a report can contain: credit reports, rental history including eviction cases, employment verification, criminal history and a score or recommendation based on criteria the landlord picks. It also notes that landlords use these reports to decide how much to charge for a security deposit.
Because the rules differ, ask before you pay an application fee:
- What income do you require, and is it measured before or after taxes?
- Do you count roommates' or a co-signer's income?
- Which screening company do you use, and what do you check?
- Which utilities and fees come on top of the rent?
If you are turned down because of a screening report, the CFPB explains that the landlord has to tell you, name the company that made the report and tell you about your right to a free copy within 60 days and to dispute anything that is wrong. Passing a landlord's income check is not the same as being able to afford the place comfortably; the budget check above is the one that matters to you.
Splitting rent with roommates or a partner
Sharing a place changes the math: what matters is your share of the housing cost compared with your own income. Take two made-up roommates sharing a $2,200 rent. Ana earns $52,000 a year and Ben $38,000. On their own, 30% of income would allow $1,300 and $950 a month.
| Person | Equal split | Share of gross income | Split by income | Share of gross income |
|---|---|---|---|---|
| Ana | $1,100 | 25.4% | $1,271 | 29.3% |
| Ben | $1,100 | 34.7% | $929 | 29.3% |
With an equal split, the same apartment is affordable by the 30% line for Ana and above it for Ben. Split in proportion to income, both pay the same 29.3%. Neither rule is the right one; it is something to agree on before signing. The guide on how to split household costs fairly compares equal, by-room and by-income splits for rent and bills, and the rent split calculator divides a rent by bedroom size.
Renting vs buying
If you are deciding between renting and buying rather than between two apartments, the questions change: down payment, mortgage rates, property taxes, upkeep and how long you plan to stay. The rent vs buy calculator compares the two over time, including the costs you never get back on either side. If buying is on the table, the home affordability calculator works out a price from income and debts the way mortgage lenders do, which uses different ratios from the rent measures on this page.
A quick way to set your rent limit
- Find your yearly gross income and multiply by 25%, 30% and 35%, then divide by 12. That is your range for rent plus utilities.
- Subtract the utilities, renters insurance, parking and other monthly costs the apartment would add.
- Compare the result with your take-home pay and check that everything else in your budget still fits.
- Add up the cash you need to move in, and make sure you have it without emptying your savings.
- Pick the lower of the numbers from steps 2 and 3. That is the rent you search with.
The 30% line is a good starting point because it is simple and widely used. Your own budget is the better finish line.
Frequently asked questions
Is the 30% rent rule based on gross or take-home pay?
On gross pay, in the official statistics. The Census Bureau applies HUD's cost burden definition to household income measured before taxes. Because taxes come out first, 30% of gross pay is a bigger share of what reaches your account: for a single filer earning $60,000 a year in Texas, $1,500 is about 35.7% of estimated monthly take-home pay.
How much rent can I afford on $60,000 a year?
At 30% of gross income, $1,500 a month for rent plus utilities, the line HUD uses for cost burden. At 25% it is $1,250, at 35% $1,750. If you pay utilities separately, subtract them first, and check what is left after rent against your other monthly costs.
Do utilities count toward the 30%?
Yes, in the official measures. HUD defines cost burden as monthly housing costs including utilities above 30% of monthly income, and the Census Bureau's gross rent adds electricity, gas, water, sewer and heating fuel to the rent when the renter pays them. A unit with utilities included can therefore be cheaper than a lower rent with utilities on top.
What does cost burdened mean?
HUD calls a household cost burdened when its monthly housing costs, including utilities, are more than 30% of monthly income, and severely cost burdened above 50%. In the Census Bureau's report on 2023 American Community Survey data, 46.3% of renter households were cost burdened and 23.9% severely cost burdened.
How much money do I need to move into an apartment?
Plan for the first month's rent, a security deposit, application fees and moving costs. In the example on this page, a $1,400 apartment needs about $3,390 up front, roughly 2.4 months of rent. Deposit limits come from state law: California and New York, for example, cap most deposits at one month's rent, while other states have other rules.
