How much rent can you actually afford?
The 30% rule is the standard starting point: keep rent under 30% of gross monthly income. The 50/30/20 view is stricter in spirit - rent belongs inside the 50% "needs" half of your budget alongside debt minimums, groceries, and utilities, so this calculator shows your needs share minus debt payments as a rent-plus-essentials ceiling. The conservative 25% cap suits anyone prioritizing savings or carrying variable income.
Whichever rule you use, landlords run their own test: most require gross annual income of at least 40× the monthly rent, which is just the 30% rule inverted. The comfort-check figure applies mortgage-style logic to renting - 36% of monthly income minus your debt payments - and is worth respecting if your debts are high, since rent and loan payments come out of the same paycheck.
Frequently asked questions
What percent of my income should go to rent?
The classic guideline is 30% of gross income. If you carry meaningful debt payments or want to save aggressively, 25% is a safer cap; in expensive cities many renters run 35-40%, which works only if other spending is genuinely low.
What does "40x the rent" mean?
Many landlords require your annual gross income to be at least 40 times the monthly rent - for a $2,000 apartment, that's $80,000 a year. It's the same math as the 30% rule (1 ÷ 0.30 × 12 ≈ 40), just flipped into an income screen.
How can I afford rent in an expensive city?
Roommates are the biggest lever - splitting a two-bedroom often beats a studio by hundreds a month. Beyond that: offer a longer lease in exchange for a lower rate, negotiate at renewal with comparable listings in hand, look one neighborhood past the popular ones, and time your search for winter, when demand and prices dip.
