What is the 30% rule?

The widely used affordability guideline says housing should consume no more than 30% of gross income. Many Phoenix landlords go further and require income of at least three times the monthly rent, which is the same 33% threshold.

What is Phoenix's median rent?

The median one-bedroom rent in Phoenix is around $1,300 per month. The tool compares your target rent to this benchmark so you can see whether you are looking above or below the local norm.

Should I use gross or net income?

Use gross, before-tax income. The 30% rule and most landlord screening are based on gross income, so that keeps the calculation consistent with how rental applications are evaluated.

What if my ratio is above 30%?

A ratio above 30% means rent is straining your budget. It is not always disqualifying, especially in high-cost markets, but it leaves less room for savings and other expenses, so consider a cheaper unit or a roommate.

Does this include utilities?

No. The 30% rule traditionally covers rent only. Phoenix utilities, especially summer cooling, can add a meaningful amount, so budget those separately on top of the rent figure shown.

Phoenix Rent Affordability Calculator

Before you sign a Phoenix lease, it helps to know whether the rent actually fits your income. This calculator applies the standard 30%-of-income affordability rule, compares your target rent to Phoenix’s median, and tells you the maximum rent you can comfortably carry.

How it works

Affordability hinges on the share of gross income spent on rent and the maximum rent at the 30% threshold:

monthly income  = annual income / 12  (or entered directly)
ratio           = target rent / monthly income
max affordable  = monthly income × 0.30
verdict         = ratio ≤ 0.30 → affordable

Landlords often phrase the same rule as needing income of at least three times the monthly rent, which is exactly the 30% threshold expressed the other way around.

Example and tips

On a $4,500 monthly gross income, the 30% ceiling is $1,350 — just above Phoenix’s median one-bedroom rent of about $1,300, so a median apartment is affordable with a little room to spare. If your target rent pushes the ratio above 30%, look at a roommate, a smaller unit, or a neighborhood further from the core, and remember to set aside extra for Phoenix’s high summer electricity bills.
