How much rent can I afford? The 30% rule vs your take-home

By the 30% rule, rent should stay under 30% of your gross monthly income: $1,000 on a $40,000 salary, $1,625 on $65,000. The typical U.S. asking rent was $1,962 in July 2026, and half of all renters are already over the line.¹ The rule is a useful start and a bad final answer; what decides it is the leftover after rent, dated bills, and minimums.

What does the 30% rule say at my salary?

The table below runs the rule at six salaries next to the number the rule ignores: what you take home. Take-home here is a single filer with the standard deduction, federal income tax and FICA only, using the 2026 brackets.³ It is before state income tax and before anything you put into a 401(k), so in a state with income tax, subtract another 3 to 6 percent.

Read the last column. The rule that sounds like "spend 30 percent" is really "spend 35 to 39 percent of what you can actually spend," and the gap widens as you earn more, because more of each extra dollar goes to tax. That is why $2,500 rent on $100,000 feels tighter than the rule implies.

Is the 30% rule gross or net?

Gross. The rule descends from a federal housing law: in 1969 the Brooke Amendment capped public-housing rent at 25% of a tenant's income, and Congress raised the cap to 30% in 1981.⁴ It was written to set rent in subsidized housing, using income before taxes, and it later drifted into general advice with the gross-income assumption still attached.

That history explains two things. First, the rule never claimed 30% was comfortable; it was a ceiling for households with little else to spend. Second, the 25% version you sometimes hear is not a stricter modern take. It is the older law, and it lands much closer to 30% of take-home, which is why some people find it more honest.

What do landlords actually check?

Not the 30% rule. Most landlords and property managers screen on a multiple of rent, usually gross income of at least 3x the monthly rent, sometimes 2.5x in expensive cities. Divide your salary by 36 and you have the most rent a typical application clears.

The two rules answer different questions. The screen tells you whether you get the keys. The budget rule was supposed to tell you whether you can live there, and it does that badly, because it never looks at the rest of your month.

What is the number that actually decides it?

The leftover. Start from take-home, then subtract in this order:

1. Rent at the amount on the lease, plus renter's insurance if the lease requires it.
2. Every bill with a due date: utilities, phone, internet, car payment and insurance, transit pass, the subscriptions that bill whether you use them or not.
3. Debt minimums: student loans, cards, buy-now-pay-later plans.

What is left has to cover groceries, gas or rides, the things that come up, and one savings goal with a name and an amount. On $65,000 with $1,800 rent, $520 of dated bills, and $310 of minimums, the leftover is about $1,900 a month. For most people that clears groceries and transport with room for a goal, so $1,800 works even though it fails the 30% rule. Swap in a $450 car payment and a $900 loan minimum and the same rent leaves about $1,400, which is where the month starts to lie to you.

The rule cannot see any of that, which is the whole reason a rent that "passes" can still feel impossible, and a rent that "fails" can be fine.

How much rent can I afford on $60k, $70k, or $80k?

The same three numbers at the salaries people search for most:

Then run the leftover. If the rent you want is between the 30% figure and the 3x screen, the leftover is what settles it. If it is above the screen, the decision is usually made for you by the application.

When is rent above 30% fine, and when is it not?

Fine, usually: the rent includes utilities or a commute you would otherwise pay for; you have no car payment and little debt; the lease is short and your income is about to change; or you are in a market where every option is over the line and the choice is between over-the-line rents.

Not fine, usually: the leftover after rent, dated bills, and minimums cannot cover groceries and transport without a card; you are counting on a raise or a roommate that has not happened yet; or the only way it works is by skipping the emergency fund entirely, which is the thing that turns one car repair into debt. If you are not sure what your fixed costs add up to, how big an emergency fund needs to be starts from that exact number.

The order to decide in

1. Divide the rent by your gross monthly income. Under 30%, over 30%, it is a fact, not a verdict.
2. Check the landlord's screen: salary divided by 36 (or 30 for a 2.5x landlord).
3. Compute the leftover from take-home, with the bills read off a 90-day statement, not guessed.
4. Name the savings goal that has to survive the rent. If the leftover clears it, sign. If not, the rent is too much for this year, whatever the rule says.

For the order your paycheck should go in once the lease is signed, read where your paycheck should go before you see it. For the salary side of the question, is $100k a good salary runs the same take-home math city by city.
