The classic rule: 30% of your gross income on rent.

It's a guideline, not a law. The honest modern range:

  • 25-30% — comfortable in most cities
  • 30-35% — common in mid-cost cities
  • 35-40% — high-cost cities (NYC, SF, LA, Seattle)
  • 40%+ — house-poor; tradeoffs elsewhere required

The math

Gross monthly income = annual salary / 12. Max rent at 30% = gross monthly × 0.30.

Example: $60,000/year → $5,000/month gross → $1,500 max rent.

Why 30% as the rule

Originated from HUD definitions of "affordable" housing. The idea: leaving 70% for everything else (food, transport, savings, debt, fun, retirement) is the threshold for not being "cost-burdened."

When 30% doesn't work

In SF, NYC, LA, and Seattle, average rents push many residents to 40%+. Choices:

  • Live further out / longer commute
  • Roommates
  • Smaller / older units
  • Different neighborhood
  • Accept higher % of income

There's no shame in being above 30% in a high-cost city. There is risk in being above 50% — minor financial events become emergencies.

Adjustments for context

  • Student loans: subtract from available income before computing rent budget.
  • Single income vs dual income: dual incomes can absorb higher rent ratios per individual.
  • Stage of life: early career often spends more % on rent (low base salary). Later career, lower %.
  • Saving for a down payment: reduce rent budget to free up savings.

Other budget guidelines

  • 20% to savings and investments
  • 50% to needs (rent, food, transport, healthcare, debt minimums)
  • 30% to wants (entertainment, dining, hobbies, travel)

The 50/30/20 rule. Rent is usually the biggest "needs" line.

What recruiters and managers know that you might not

If you're moving for a job:

  • Ask about cost-of-living adjustments.
  • Negotiate relocation.
  • Ask about housing stipends if remote-friendly companies offer them.

The bigger pattern

Rent budget is a function of total compensation, not just base salary. Higher comp + lower-cost city is leverage. Lower comp + higher-cost city is constraint.
