Rent Affordability Calculator
Find out how much rent you can comfortably afford based on your gross income — at the 30% rule of thumb or any other threshold.
Standard (30%)
At 30% of gross income, max recommended rent is $1,500.00/month
The 30% rule of thumb — long the standard guidance for healthy household budgeting. Most renters at this level can also save and cover normal expenses.
Rent at standard thresholds
Results update as you type. Figures are based on gross income; net (after-tax) affordability is lower. The thresholds are population-level rules of thumb, not a substitute for your full budget.
Formula
One multiplication:
max_rent = monthly_gross_income × threshold_pct / 100.
The classic threshold is 30% — popularised by US HUD in the 1980s and adopted across global
tenant-referencing convention. The four named bands (25 / 30 / 35 / 40%) are common waypoints,
not a sharp clinical threshold; pick whichever fits the rest of your fixed costs.
When to use this calculator
Apartment hunting in the US almost always runs into a hard income test, so it pays to know your number before you tour. Enter your gross income and this calculator shows the rent you can comfortably carry at the classic 30% rule — which lines up closely with the 3x rent rule most landlords use when they screen applicants. Run it first and you can filter listings to the ones you would actually qualify for, instead of falling for a place your application can't clear.
It is most useful when you are setting a search budget, weighing one neighborhood against another, or checking whether your paycheck meets a building's 3x gross income requirement. Because the threshold is adjustable, you can also test a stretch: see what 35% buys you in a pricier zip code, then decide whether the squeeze on the rest of your budget is worth it.
Reading your result
The headline number is the monthly rent that keeps you at or under your chosen share of income. At 30% of gross it mirrors the 3x rent rule landlords apply, so it doubles as a quick read on whether you would pass screening. The 25% band is the comfortable, save-more choice; the 35% and 40% bands are flashing lights that the rest of your budget — groceries, car, student loans — is going to feel the pinch.
Keep in mind the figure is built on gross pay, before federal, state and FICA taxes come out. Your take-home is meaningfully lower, so a rent that is 30% of gross can be closer to 40% of net in a high-tax state like California or New York. Landlords screen on gross, but your actual budget runs on what hits your bank account — so check the rent against your net pay too.
A worked example
Say you earn $60,000 a year, or $5,000 a month gross. At the 30% rule, your comfortable rent ceiling is $1,500 a month — and since most landlords want gross monthly income at 3x the rent, $5,000 divided by 3 is about $1,667, so you would qualify for that $1,500 unit with room to spare. Pull back to the cautious 25% band and the figure is $1,250; stretch to 35% and it climbs to $1,750, but that extra $250 a month is money pulled away from savings, retirement and everything else.
Common mistakes to avoid
Your affordability figure is only as reliable as the inputs, and a handful of slip-ups catch renters out.
- Budgeting on gross income when you actually live on take-home pay — always re-run the rent against your net monthly figure, especially in high-tax states.
- Forgetting add-ons like utilities, internet and renter's insurance, which can run $150–$300 a month on top of the rent.
- Overlooking move-in costs: a security deposit (often one month's rent), first month, and sometimes last month due up front can mean two to three months' rent before you have the keys.
- Assuming you'll clear screening on income alone — most landlords also run a credit check, and a thin or low score can mean a co-signer or a larger deposit.
Renting in the US: screening and deposits
Most American landlords screen applicants on two things: income and credit. The income side is usually the 3x rent rule — gross monthly income at least three times the monthly rent — and the credit side is a hard pull on your report, with many properties looking for a score in the high 600s or above. If your income or credit falls short, a co-signer or guarantor whose income typically clears 4x–5x the rent can often get you approved.
Security deposits and their handling are governed at the state level, not federally, so the rules vary widely. Many states cap the deposit at one or two months' rent and require it to be returned within 14–30 days of move-out, sometimes in a separate or interest-bearing account. Check your state's specific limits and timelines, and get the apartment's condition documented in writing at move-in so your deposit is easier to recover later.

Frequently asked questions
What's the 30% rule?▾
A US Department of Housing and Urban Development convention from the 1980s: a household is 'rent-burdened' if rent + utilities exceeds 30% of gross income, 'severely rent-burdened' above 50%. The 30% threshold has been the default rental-affordability rule for 40+ years, even though housing-cost growth has pushed huge swaths of US renters above it (especially in coastal markets).
Should I use gross or net (take-home) pay?▾
Affordability rules of thumb quote gross. Most US landlords use a 3× rent rule — they want to see gross monthly income at 3× the rent, which is the 33% threshold. For your own budgeting, the relevant question is what % of *net* pay rent represents — at federal + state tax brackets, that figure is typically ~10 percentage points higher than the gross figure. A 30% gross rent burden is more like 40% of take-home in California or New York.
Does this include utilities?▾
HUD's official rent-burden definition includes utilities; many calculators (this one included) work on rent alone for clarity. Add ~$150–$300/month for utilities, internet, and renter's insurance on top of rent for a fuller picture. In states with high heating or AC costs, that figure runs higher.
What is the 3x rent rule?▾
Most US landlords require gross monthly income at least 3× the monthly rent — equivalent to a 33% rent-to-income ratio. Some markets and luxury buildings use 3.5× or 4×. If your individual income doesn't pass, a co-signer or guarantor can typically substitute (their income usually has to clear 4–5× the rent).
What's the difference between rent burden and 'cost burden'?▾
Rent burden specifically refers to renters; cost burden includes both renters and homeowners (mortgage + property tax + insurance + utilities). HUD reports both. The 30% threshold is the same; only the cost composition differs.
Is 30% achievable in expensive cities?▾
Often not. In Manhattan, San Francisco, San Jose, and several other markets, median renter rent burden is 40%+. The honest interpretation is that the 30% rule has become aspirational rather than typical in coastal metros, and households in those markets accept higher rent burdens by economic necessity. The calculator gives you the math — your local market dictates what's actually rentable.
