Rent Affordability Calculator

The short answer

• The 30% rule: rent up to 30% of gross monthly income. On $60,000 a year, $1,500 a month.
• The 40× rule: landlords want a yearly income of 40 times the monthly rent. That also allows $1,500.
• A 50/30/20 budget on take-home pay may allow less once other essentials are counted.
• For rent of $2,000, both income rules need $80,000 a year.

The 30% rule

The idea that housing should cost no more than 30% of income comes from federal housing policy. HUD counts households paying more than 30% of income on housing as cost-burdened, and more than 50% as severely cost-burdened. It uses gross income, before tax.

It is simple and widely used, but it ignores taxes, debts and the cost of living where you are. On a low income, 30% can still leave too little for everything else; on a high income, spending 30% may be easy.

The 40× rule landlords use

Many landlords and property managers, especially in big cities, ask that your yearly gross income be at least 40 times the monthly rent. For a $1,800 apartment, that is $72,000 a year. Some use 30× or 35×; others want 2.5 or 3 times the rent in monthly income, which is the same idea. Ask before you apply, because application fees are usually not refundable.

Why the two rules agree

30% of monthly income is 0.3 ÷ 12 = 2.5% of yearly income, and yearly income ÷ 40 is also 2.5%. So the 30% rule and the 40× rule always give the same rent. Landlords who use 3× monthly income allow a little more: about 33% of gross pay.

The 50/30/20 budget

The 50/30/20 budget splits take-home pay three ways:

Rent comes out of the 50% for needs, after your other essentials. Because it starts from take-home pay, it reflects taxes, and because it subtracts your other needs, it reflects your real costs.

Debts and the 36% line

Lenders treat 36% of gross income as a sensible ceiling for housing plus debt payments. The calculator uses the same line for renters: rent plus car, student loan and card payments up to 36% of gross pay. With $300 of debts on $60,000 a year, that leaves $1,500; with $600, only $1,200, and that becomes the limit. Our debt-to-income calculator shows your ratios in full.

A worked example

The 50/30/20 budget sets the limit here. A landlord would approve $1,500, but paying it would mean cutting wants or savings below their shares. The full split of $4,199: $2,100 for needs, $1,260 for wants and $840 for savings.

Rent by income

As income rises, taxes take a bigger share, so the gap between the gross-income rules and a take-home budget widens.

Income needed for a rent

Multiply the monthly rent by 40 to get the yearly income landlords usually look for:

Enter any rent in the calculator’s “Check a rent” box to see the income each rule needs and what share of your pay it would take.

Gross pay vs take-home pay

Gross pay is your salary before anything is taken out. Take-home pay is what reaches your bank account after federal income tax, Social Security (6.2%), Medicare (1.45%), state and local tax, and deductions such as 401(k) contributions and health insurance. The calculator estimates take-home pay from 2026 federal rules and your state, or you can enter the figure from your pay stub. Our paycheck calculator gives a full breakdown.

Where you live changes take-home pay

On $60,000 a year, single, with no pre-tax deductions, estimated monthly take-home pay in 2026 is:

Each figure uses that state’s 2026 brackets, deductions and exemptions. The difference is a few hundred dollars a month, which matters most in a tight budget. Some cities, such as New York City, add a local income tax too.

Costs beyond the rent

• Utilities: electricity, gas, water, trash and internet, unless included.
• Renters insurance, which many leases require.
• Parking, pet rent and amenity fees.
• Commuting: a cheaper apartment farther out can cost more once gas or transit is counted.

Put these in “other essentials” so the 50/30/20 figure reflects them.

Money up front

Moving in usually takes first month’s rent, a security deposit (often one month’s rent, sometimes more; many states cap it), application fees and sometimes a broker fee. Budget for two to three months’ rent in cash, plus moving costs.

Roommates and couples

When several people sign a lease, landlords usually add up the incomes, though some want each person to meet a share of the requirement. Enter the combined income to see the household budget, and agree how rent and utilities will be split before you sign. Everyone on the lease is usually responsible for the whole rent.

If you do not meet the income rule

• Ask for a guarantor or co-signer, often a parent, with a higher income.
• Offer a larger deposit or prepaid rent, where state law allows.
• Show savings, a job offer letter or other income such as benefits.
• Look at smaller landlords, who may be more flexible than large management companies.

When rent takes too much

Many renters do pay more than 30%, especially in expensive cities. Paying more is sometimes worth it for a shorter commute, but go in knowing the trade-off.

Renting and saving to buy

If you plan to buy, a rent below your comfortable figure leaves room to save a down payment. When you are ready, our home affordability calculator shows the price your income supports, and the mortgage calculator shows the monthly payment on a specific home.

Using the calculator well

1. Enter your yearly income before tax, for everyone on the lease.
2. Add your other essential costs and monthly debt payments.
3. Under More options, pick your state and filing status, or enter take-home pay from your pay stub.
4. Type a rent you are considering into “Check a rent”.

What landlords check

Income is only one part of a rental application. Most landlords also run a credit check, look at your rental history and call past landlords, and many run a background check. They usually ask for recent pay stubs, an offer letter or bank statements, and for the self-employed, tax returns or 1099s.

Before you apply, check your credit reports for free at the official site, AnnualCreditReport.com, and fix any errors. Have your documents ready in one file, because good apartments in busy markets often go to the first complete application.

Rent increases and renewals

Your rent is fixed only for the length of the lease. At renewal, the landlord can usually raise it, subject to notice rules and, in a few states and cities, rent control or stabilization rules. A rent that only just fits today may not fit after a rise of several percent next year, while your pay may not rise as fast.

Leaving some room below your comfortable figure gives you a buffer. When a renewal offer arrives, compare it with similar apartments nearby; moving has its own costs, but so does accepting a large increase without asking whether there is room to negotiate.

Comparing two apartments

Compare the total monthly cost, not just the rent. An apartment that costs $100more but includes utilities, parking or a much shorter commute can be the cheaper choice. Add up rent, expected utilities, renters insurance, parking, fees and commuting for each, then run the larger total through the calculator’s “Check a rent” box.

Think about time too. A long commute costs hours each week that you might otherwise spend working extra shifts, resting or with family, and that has real value even if it does not show up in a budget.

An emergency fund comes first

Rent is due every month whether or not you have a surprise car repair or a gap between jobs. A cushion of even one month’s rent in savings makes a late payment much less likely, and a late payment can bring fees and, in the worst case, an eviction filing that follows you to future applications.

The 20% savings share of a 50/30/20 budget is meant for this. If your rent leaves no room to build a cushion, that is a sign it is too high for now.

Help with rent

If rent takes more than you can manage, help may be available. HUD’s Housing Choice Voucher program, run by local public housing agencies, helps eligible lower-income households pay rent in the private market, though waiting lists are often long. Many cities, counties and charities run emergency rental help for a short-term crisis. Calling 211 connects you with local programs.

If your income varies

Freelancers, gig workers, people paid on commission and anyone with seasonal hours should budget on a cautious income figure, not a good month. A simple approach is to use your lowest-earning three months of the past year, multiplied by four, as the yearly income in the calculator. If you are self-employed, remember that no tax is withheld: set aside money for quarterly estimated taxes and self-employment tax before working out what is left for rent.

Landlords will usually want two years of tax returns or several months of bank statements to show steady income, so expect to provide more paperwork than someone with a W-2 job.

Students and first jobs

If you are moving for a first job, many landlords accept a signed offer letter as proof of income. Your first paycheck may arrive two to four weeks after you start, so plan for the deposit and the first month’s rent from savings. Students without income usually need a guarantor. Starting with a roommate or a smaller place for a year lets you build a rental history and savings before taking on more.

Estimating utilities

Utilities vary with the size and age of the building, the climate and whether heating is gas or electric. Ask the landlord or current tenant what bills usually run in summer and winter, and check whether water, sewer and trash are included. Older buildings with poor insulation can mean high heating or cooling bills that wipe out a lower rent. If the landlord pays some utilities, the rent may look high but the total cost can be lower.

Internet and phone plans are easy to forget. Add them to other essentials too, so the budget reflects the full cost of living in each place.
