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

  1. Take your monthly take-home pay.
  2. Multiply by 0.30, that's your comfortable rent ceiling.
  3. Multiply by 0.40, that's your stretch limit.
  4. 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.

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.
