How much of your income should go to rent?
The classic answer is 30%. The honest answer is: it depends on your debts, your city, and how close you are to a real emergency fund. Here is the plain-English version, with the numbers that matter and a free tool to check your own situation.
The 30/40/50 rule in one paragraph
Under 30% of take-home pay on rent is the comfortable zone, you keep room for saving and surprises. Between 30% and 40% is workable if your debts are low. Above 50% is what HUD calls "severely cost-burdened," and it's where most budgets start to break.
You can check your exact zone in the rent share calculator.
Green · ≤ 30%
Room for savings and a real cushion.
Yellow · 30–40%
Workable, but thin margins.
Red · 50%+
Cost-burdened. One bad month hurts.
Rent by salary: quick benchmarks
These use take-home pay (roughly 80% of gross) and the 30% guideline. Your actual numbers will vary with state taxes and benefits.
- $40,000/yr → ~$2,650 take-home → comfortable rent around $800
- $60,000/yr → ~$4,000 take-home → comfortable rent around $1,200
- $80,000/yr → ~$5,300 take-home → comfortable rent around $1,600
- $100,000/yr → ~$6,600 take-home → comfortable rent around $2,000
If your city pushes you into the yellow zone, the fix usually isn't "earn more", it's cutting one other fixed cost or splitting rent with a roommate.
When the 30% rule doesn't fit
The rule was written for stable, single-income households with modest debt. It stops working in three cases:
- High-cost cities. In NYC, SF, or Boston, 40% is often the realistic floor. Tighten the rest of the budget instead of pretending 30% is possible.
- Heavy debt. If loans eat 15%+ of your income, aim for rent closer to 25%. Use the debt payoff calculator to see how fast you can free that up.
- No emergency fund yet. Cheap rent buys time to build one. The emergency fund calculator gives you a real target.
Should you rent or buy?
Rent is a ceiling on your monthly housing cost. A mortgage is a floor, taxes, insurance, and repairs stack on top. If you're weighing the two, run your numbers through the home affordability calculator first, then compare it to a rent you'd actually sign for.
The one-minute check
- Take your monthly take-home pay.
- Multiply by 0.30, that's your comfortable rent ceiling.
- Multiply by 0.40, that's your stretch limit.
- If the rent you're eyeing is above the stretch limit, something else in the budget has to give.
Or skip the math and use the rent share calculator , it does all four steps and shows your green/yellow/red zone.
Two related questions people ask next: how much rent can I afford? and, if you're weighing a first home instead, rent vs buy, which can I actually afford? On a six-figure income, start with how much house can I afford on $100k?
FAQ
Is the 30% rule based on gross or net income?
The original rule uses gross income, but for a realistic budget most planners apply it to take-home pay after taxes and retirement contributions.
How much rent can I afford on $60,000 a year?
Take-home is roughly $4,000/month, so the 30% guideline puts comfortable rent near $1,200 and the stretch ceiling near $1,600.
What if rent in my city is over 40% of my income?
You're cost-burdened by HUD's definition. Options: a roommate, a smaller unit, a cheaper neighborhood, or raising income before signing a longer lease.
