How to Use This Calculator
Enter your annual gross income to get your maximum affordable rent under the classic 30% rule, plus a comfortable 25% target. Add your monthly take-home pay to see the same limits against the money you actually receive, which is the stricter and more honest budget. If you have a specific apartment in mind, enter its rent (plus utilities and renters insurance) and the calculator checks it against your income and tells you what income a landlord would require.
Enter your Annual Gross Income (before taxes). This drives the standard 30% rule number that landlords use.
Optionally enter your Monthly Take-Home Pay to see your budget against real spendable dollars, the number that matters for your own planning.
If you are apartment hunting, enter the Target Rent and your estimated Utilities + Insurance to check whether it fits and what income the landlord will want to see.
The 30% Rule, Explained
The 30% rule traces back to the 1969 Brooke Amendment, a federal law that capped public housing rent at 25 percent of income (later raised to 30 percent). It stuck because it is simple and roughly right: at 30 percent for housing, most households can still cover food, transport, savings, and debt on the remaining 70 percent. Spend 40 percent or more and something has to give, usually savings first, then everything else. The rule uses gross income because that is what landlords and lenders can verify, but your personal budget should be built on take-home pay.
Worked Example
Earning $80,000 a year: gross monthly income is $80,000 / 12 = $6,666.67. The 30% rule gives a maximum rent of $6,666.67 x 0.30 = $2,000 a month. The comfortable 25% target is $1,666.67 a month. If your take-home pay is $5,000 a month, 30% of net is $1,500, which is the tighter budget to actually live by. Now flip it around: a $2,200 apartment needs $2,200 x 3 = $6,600 a month in gross income, or $79,200 a year, to satisfy a landlord using the 3x rule. Add $180 in utilities and $25 in renters insurance and the true cost is $2,405 a month, which needs $86,580 a year of income.
What Landlords Actually Require
The 3x rent income requirement is the 30% rule in disguise: rent x 3 in monthly income means rent is exactly 30% of income. Most corporate landlords apply it rigidly and verify with recent pay stubs, W-2s, or bank statements. Independent landlords are often more flexible, especially if you offer a larger deposit, show strong savings, or have a guarantor. They also run credit checks: a score above 650 with no recent collections keeps most doors open, while weak credit may push the income bar to 3.5x or require a co-signer. Students and new graduates without income history typically need a guarantor earning 80x the monthly rent annually in expensive markets, or 40x in standard ones.
When 30% Does Not Work
In high-cost metros, insisting on 30% can mean an unsafe neighborhood or a brutal commute. Spending 35% on rent to live near work and skip a car payment can be the better financial move, because housing plus transportation is the number that really matters. The playbook for stretched markets: get a roommate (the single biggest lever), look one transit stop farther out, negotiate with a longer lease or upfront payment, and keep every other fixed cost lean. Whatever you spend on rent, protect two things first: a small emergency fund and retirement contributions, because a cheap apartment that stops you from saving is not actually cheap.

Frequently Asked Questions
What is the 30% rule for rent?
The 30% rule says your rent should cost no more than 30 percent of your gross (pre-tax) monthly income. On an $80,000 salary, that is $6,666.67 a month in gross pay, and 30 percent of it is $2,000 in rent. The rule comes from a 1969 federal housing law that defined affordable housing as costing under 30 percent of income, and landlords and lenders still use it as the standard benchmark.
Is spending 30% of my income on rent too much?
Thirty percent is the ceiling, not the target. Many financial planners suggest 25 percent as a comfortable level that leaves room for saving, and going above 30 percent makes you "rent burdened," a term housing researchers use for households stretched by housing costs. If you are early in your career with rising pay ahead, stretching toward 30 percent for a good location can make sense. If you are carrying debt, aim under 25 percent instead.
How do landlords decide whether I can afford the rent?
Most landlords require your gross monthly income to be at least 3 times the monthly rent, which is exactly the 30% rule flipped around. For a $2,000 apartment they want to see $6,000 a month in income, or $72,000 a year. Some landlords and property managers use 3.5x or even 4x in expensive markets, and they verify it with pay stubs, bank statements, or an employment letter during the application.
Should I use gross income or take-home pay for the 30% rule?
The classic rule uses gross income (before taxes and deductions), and that is what landlords check. But your real spending power is your take-home pay, so running the numbers on net income is the safer move for your own budget. On an $80,000 salary with typical taxes and deductions, take-home might be around $60,000, making 30 percent of net about $1,500 a month. This calculator shows both so you can see the difference.
Does the 30% rule include utilities and renters insurance?
Strictly, the rule covers rent alone, but a smart budget counts the full cost of the roof over your head: rent plus utilities, renters insurance, parking, and any mandatory fees. A $1,800 apartment with $200 in utilities and $25 in insurance really costs $2,025 a month. Enter your target rent below along with those extras to see the true monthly housing cost against your income.
What if rents in my city make 30% impossible?
In high-cost cities like New York, San Francisco, or Los Angeles, many renters spend 35 to 45 percent of income on housing. If that is your reality, the rule becomes damage control: get a roommate, live farther out near transit, negotiate, or trade space for location. Compensate elsewhere by keeping other fixed costs low, especially car payments, since housing plus transportation is the real budget killer.
