What is the 30% rule for rent?

The 30% rule says you should spend no more than 30% of gross monthly income on rent. It is a widely used guideline that leaves enough room for other essentials, debt, and savings.

Should I use gross or net income?

The classic 30% rule uses gross (pre-tax) monthly income, and that is what this tool expects. Some landlords also require gross income to be at least three times the rent, which is the same threshold.

What is the median rent in Miami?

The median 1-bedroom rent in Miami is around $2,300 per month. The tool compares your affordable maximum against this and against cheaper and pricier neighborhood tiers.

Why does the calculator show neighborhood tiers?

Rents vary widely across Miami, so the tool maps your maximum affordable rent onto budget, median, and premium tiers to show realistically where you can live, not just a single yes or no.

What if a listing is above 30% of my income?

It flags the listing as a stretch. Spending 30% to 40% is possible if you have low debt and savings, but above 40% most budgeting frameworks consider you rent-burdened.

Can you afford that Miami apartment?

Miami rents are well above the national average, so a quick affordability check saves a lot of disappointment. This calculator applies the standard 30%-of-income rule: housing should consume no more than 30% of your gross monthly income. It compares your maximum affordable rent against Miami’s median 1-BR rent of about $2,300 and shows which neighborhood tiers are realistically within reach.

How it works

The 30% rule sets your affordable ceiling directly from income:

max_affordable_rent = gross_monthly_income * 0.30

For a specific listing, the tool computes the share of income it would take:

rent_to_income = listing_rent / gross_monthly_income

A ratio at or below 0.30 is comfortable, 0.30 to 0.40 is a stretch, and above 0.40 is rent-burdened. The tool also maps your ceiling onto Miami neighborhood tiers — budget, median, and premium — so you can see where you fit rather than just a pass or fail.

Tips and example

If you earn 6000 gross per month, your 30% ceiling is 1800. Miami’s 2300 median 1-BR exceeds that, so the median tier is a stretch at about 38% of income; a budget-tier listing would fit. To comfortably afford the median $2,300, you would need roughly 7667 gross per month. Many renters in expensive metros target the higher 3x-rent threshold landlords use, which is mathematically identical to the 30% rule.
