Can I Afford This Rent? Introducing the Housing Affordability Calculator
If you just want to check a number, skip this post: open the Housing Affordability Calculator, type in your pay and a rent amount, and it does the rest. Everything below is just the story of why we built it.
“Can I afford this?” is one of the hardest questions to answer when you are trying to get back into housing — and one of the easiest to get wrong under pressure. A rent that looks fine on a listing can quietly eat most of a paycheck once utilities, the bus, and food are in the picture. We built a calculator that puts those numbers in front of you in a few seconds, privately, with no judgment attached.
What the tool does
The Housing Affordability Calculator takes three things — your pay, a rent amount, and (optionally) your other must-pay costs — and answers four questions at once:
What share of my pay goes to rent? It shows the percentage against the standard most agencies, landlords, and assistance programs use: rent plus utilities should stay at or below 30% of income. Above 30% is “cost-burdened,” above 50% is “severely cost-burdened.” The page names where you land in plain words and a simple bar — not to grade you, but so you know the same number a caseworker or landlord is looking at.
What is left after rent? The 30% rule is a blunt instrument — it does not see the bus pass, the phone bill, or the kids. So right next to the percentage, the tool shows the money left after rent and the costs you entered. Two apartments at the same rent can leave very different amounts to live on, and that is often the number that actually matters.
What rent can I afford, and what income does this rent need? It works the math both directions: 30% of your pay (a rent target to aim for) and the income this particular rent would require to sit at 30% — plus the gap between that and what you make now. If a place is a stretch, you can see exactly how big the stretch is.
Built for real budgets
Most affordability calculators assume you know your gross, before-tax salary. Many people only know their take-home pay, or get paid by the hour, every two weeks, or in amounts that change. So this one lets you enter pay per hour, per week, every two weeks, or per month, and tell it whether the number is take-home or before taxes. If you use take-home, the tool is a little more cautious — which is usually the safer side to be on.
Like every Common Ladder tool, it collects no personal information and requires no account. The math runs entirely in your browser. Your entries stay on your own device so the page remembers them if you come back, and a Clear button wipes them instantly. Nothing is ever sent to us or anyone else. It loads fast on a low-end phone and works at 375 pixels wide.
When the number is hard
Plenty of people pay well over 30% of their income on rent, because rents are high and wages have not kept up. That is not a personal failure, and the tool does not treat it like one. When a rent comes back as cost-burdened, the page points to real help instead of leaving you with bad news: the Stay-Housed Navigator for rent and utility assistance in Maricopa County, 2-1-1 for rental help anywhere in the country, the Benefit Screener for income you may be leaving on the table, and our guide to emergency utility assistance for lowering the bills around the rent.
When to use it
Use the calculator before you sign a lease, when you are weighing two places, or when you are figuring out what you would need to earn to make a move work. Case managers: it is built to be handed across a desk or texted as a single link, and it pairs with My Ladder for clients building a budget and a plan.

A budgeting guide, not financial advice. The 30% standard is a widely used rule of thumb, not a promise from any landlord or program. Affordability depends on your whole picture. If the numbers are tight, free help is a call away at 2-1-1.
