A rent listing shows the price of the space. Your household needs to see what remains after that price joins the bills you already have. Write down the whole monthly picture before treating a rental as workable.
The free Rent Affordability Estimator combines proposed rent, utilities, existing payments, and other essentials. It also shows a housing percentage. Read the remaining dollars alongside that percentage, because a broad ratio cannot describe every household's obligations.
Build the month that would follow the move
Start with household take-home pay, using money actually available after payroll deductions. Then list payments that will continue: transport, debts, care needs, food, insurance, and other regular commitments. Avoid putting the same car payment in both the debt field and another category.
Check what each rental quote includes. Water, electricity, parking, internet, or other charges may be billed separately. Mark uncertain amounts as estimates. If the new location changes commuting costs, update those in a separate scenario so you can see both the housing and travel effect.
The CFPB's spending-review guidance recommends checking several months of records and including less frequent expenses. Although that page supports homebuying preparation, its record-review method is also useful for assembling this monthly spending list. The rent calculator itself does not determine rental eligibility.
Compare two fictional rents
Assume take-home income of $4,200. The first rental costs $1,400, with $250 in utilities paid separately. Existing loan, card, and car payments total $450, and other essential spending totals $1,300.
Housing costs $1,650: $1,400 plus $250. Divide $1,650 by $4,200 and housing uses about 39.29% of take-home pay, displayed as 39%. After all entered expenses, the remainder is $800: $4,200 minus $1,650 minus $450 minus $1,300.
Now change only the rent to $1,650. Housing rises to $1,900. The housing share is about 45.24%, displayed as 45%, and the monthly remainder is $550. The $250 rent increase reduces the remainder by exactly $250 because every other input stayed fixed.
Neither result tells you whether a landlord will approve an application or whether the rental fits your needs. It tells you what those two prices do to this particular list of monthly numbers.
Put proposed rent into the rest of your month
Start with take-home income and the bills that will continue after a move. Record deposits and moving costs on a separate cash checklist.
Your numbers
What that means
Rent and utilities come to $1,470 a month, which is 41% of your take-home pay. After housing, your existing payments and everything else, $810 is left over each month. A rent of about $860 would put housing at the 30 percent guideline.
Over 40 percent of take-home on housing leaves very little room for anything going wrong. It is doable, but it is tight, and there is no cushion in it.

What this assumed
- Uses take-home pay. Letting agents usually assess against gross income, so their figure will be higher.

How to run it, step by step
- 1Enter Household take-home per month. Use $4,200 for the fictional example. Do not substitute gross salary for the money available after payroll deductions.
- 2Add Rent per month and utilities. Enter $1,400 rent and $250 for Utilities not included in rent. Confirm what the quoted rent actually includes.
- 3Add existing payments and essentials. Enter $450 for Loan, card and car payments per month and $1,300 for Everything else you must pay. Count each obligation once.
- 4Compare a second rent. Change only Rent per month to $1,650. Keep the first result so you can see exactly what the $250 increase changes.
How to read what it gives you
- At $1,400 rent, housing plus utilities totals $1,650 and leaves $800 after all entered costs. Housing share is about 39.29%, displayed as 39%.
- At $1,650 rent, housing totals $1,900 and the remainder is $550. The housing share rounds to 45%.
- The tool's 30% reference uses take-home income. It is not a landlord's screening standard, legal eligibility rule, or universal affordability decision.
The tool is free, it does not expire, and you can put it on your own website if you want it there. Nothing on this page is locked.

Understand the percentage reference
The tool includes a 30% housing reference calculated from take-home pay. In the example, $4,200 times 30% equals $1,260 for housing including utilities. Subtract the entered $250 utilities and the reference rent is $1,010.
That is the source of the displayed reference, not a statement that an appropriate $1,010 rental exists. It is not a universal standard, a required approval rule, or a substitute for considering the remaining dollars. A household with different care, transport, or medical obligations may experience the same rent very differently.
The colors and labels are prompts to inspect the numbers. They cannot see missing bills, unstable income, access needs, or a commitment you forgot to enter. Avoid calling the $800 or $550 available spending until those omissions have been reviewed.
Put move-in cash on a separate page
The monthly subtraction does not include everything needed before keys are handed over. Make a separate list using actual quotes and lease terms. Include the first rent payment, required deposits, application costs, moving arrangements, utility setup, and any overlap with the previous home.
For a fictional cash example, suppose first-month rent is $1,400, the deposit is $1,000, the move costs $350, and utility setup costs $150. Those items require $2,900 up front. If $4,000 is available for the move, $1,100 remains after those listed items. This separate arithmetic does not establish which charges are permitted or refundable; check the actual terms and applicable rules.

- Monthly remainder after listed obligations:
- Savings commitments still to include:
- Deposits, fees, and first payment due dates:

- Unanswered question and who can confirm it:
Keep each option on the same basis. A lower rent with a longer commute needs a revised transport line, while a larger deposit belongs on the move-in page. Finish by resolving the largest unknowns and rerunning the comparison. The result should be a clearer decision sheet, not an unexplained green light.
Questions people actually ask
Does a favorable color mean I will qualify for the rental?
No. The tool does not assess landlord screening, credit, deposits, eligibility, or a particular lease. It compares the numbers you enter.
Are deposits included in the monthly result?
No. Keep deposits, application costs, moving expenses, and any overlapping rent on a separate move-in cash sheet.
Is 30% of take-home pay the right housing amount for everyone?
No. It is a reference built into this tool. Actual obligations, local costs, household needs, and savings commitments require their own review.
