Which number should you use?

The 30% rule ("spend no more than 30% of gross income on rent") is the classic budgeting guideline for tenants. The 3× rent rule ("monthly income at least three times the rent") is the flip side most landlords use to screen applicants — they're the same math viewed from opposite ends.

The conservative figure subtracts your existing monthly debts first, then caps total debt + rent near 36% of income (a common debt-to-income benchmark). If you carry car or student-loan payments, this is the more realistic ceiling.

These are guidelines, not rules — high earners can comfortably spend more, and expensive metros often push past 30%. Use the number that fits your full budget.
