What is the 30% rule?

The 30% rule is a widely used budgeting guideline that recommends spending no more than 30% of your gross monthly income on rent. Spending more is often called being rent-burdened, and above 50% is severely rent-burdened.

What is the median rent in Tucson?

Tucson's median one-bedroom rent sits around $1,000 per month, which is below the US average. This tool compares your target rent to that local benchmark so you can see whether a listing is priced typically for the city.

Should I use gross or net income?

The classic 30% rule uses gross income, meaning your pay before taxes and deductions. This tool follows that convention. If you prefer to budget on take-home pay, enter your net monthly income instead and treat the ceiling as more conservative.

Does this include utilities?

No. The calculator looks at base rent only. Tucson summers drive high cooling costs, so budget an extra cushion for electricity and water on top of the rent figure shown here.

Is the affordable rent a hard limit?

It is a guideline, not a rule. Landlords in Tucson often want income of about three times the monthly rent, which aligns with the 30% threshold. Lower debt or savings can justify going slightly higher, but the ratio warnings still apply.

Tucson Rent Affordability Calculator

How much rent can you actually afford in Tucson, and is that listing you found a fair deal? This calculator applies the standard 30%-of-income budgeting rule to your income and compares any rent you are weighing against Tucson’s roughly $1,000 median one-bedroom rent.

How it works

The affordable rent ceiling is simply 30% of your gross monthly income. For a specific listing, the rent-to-income ratio is the listing rent divided by your monthly income:

affordable rent ceiling = monthly income × 0.30
rent-to-income ratio    = listing rent ÷ monthly income

Housing guidelines classify a ratio at or below 0.30 as affordable, between 0.30 and 0.50 as rent-burdened, and above 0.50 as severely rent-burdened. The tool also compares the listing to the local median so you can tell whether the price is typical for Tucson.

Example and notes

If you earn $3,500 per month, your 30%-rule ceiling is $1,050, which comfortably covers a typical Tucson one-bedroom near the $1,000 median. A $1,400 listing would push your ratio to 40%, flagging you as rent-burdened. Remember that this counts base rent only. Tucson’s hot summers can add a substantial cooling bill, so leave headroom for utilities on top of the figures shown here.
