How much rent can I afford?
The most common guideline is the 30% rule: spend no more than 30% of your gross (pre-tax) monthly income on rent. If you earn $5,000 per month, that's a $1,500 maximum. Many landlords use a related rule — requiring that your annual income be at least 40× the monthly rent (the "40x rule"), which works out to about the same 30% threshold.
The 30% rule is a starting point, not a hard limit. In high-cost cities many people spend 35–50% (becoming "rent-burdened"), while aggressive savers target 20–25%. A smarter check factors in your other debts: the 36% rule says total monthly debt payments, including rent, shouldn't exceed 36% of gross income. This calculator shows both the straight percentage recommendation and a debt-aware maximum so you can budget realistically.
Max rent = 30% of gross monthly income. A widely used affordability benchmark for budgeting and landlord screening.
Total debts plus rent should stay under 36% of gross income. The debt-aware figure subtracts your existing monthly debt payments.
In expensive metros, 30% may be unrealistic. Spending over ~30% makes you "rent-burdened" — fine short-term, but watch your savings rate.
Many landlords require annual income ≥ 40× monthly rent (e.g., $60,000/yr qualifies for $1,500 rent). That mirrors the 30% guideline.
The traditional guideline caps rent at 30% of gross income, a threshold that originated in US housing policy and is now the standard definition of being "cost-burdened". Many landlords apply a stricter test, requiring gross annual income of 40 times the monthly rent — which works out at 30% exactly, since 40 × monthly rent ÷ 12 months is 3.33 times annual rent. The guideline is increasingly unrealistic in expensive metros, where a majority of renters exceed it, and the more useful personal test is what remains after rent and taxes rather than the ratio itself.
Maximum rent = Gross monthly income × 30%Landlord test: Gross annual income ≥ 40 × monthly rentCost-burdened above 30%; severely cost-burdened above 50%where:
Assumptions: Uses gross income, so the share of take-home pay is considerably higher — often 40% or more of what actually lands in the account. Excludes utilities, renters insurance and parking, which many buildings charge separately.
Apply both the 30% rule and the landlord 40× test, then check against take-home pay.
Result$1,950 a month qualifies — but that is 40% of take-home pay
The gap between 30% of gross and 40% of net is the reason the guideline feels tighter in practice than it sounds. Someone in a high-tax state sees an even wider gap, which is why the ratio is better treated as a landlord screening threshold than a personal affordability test.
