Yalnızca tahmin. Pratik kural: brüt gelirin maksimum %30'u kira; daha sıkı %25 daha fazla marj bırakır. Ev sahipleri genellikle %36'nın altında DTI ve %30'un altında kira-gelir oranı ister.
The classic “30% rule” for rent affordability — spend no more than 30% of gross monthly income on rent — has its origins in the 1969 Brooke Amendment to US public housing law, which capped public- housing tenants' rent at 25% of income (later raised to 30%). The number stuck and became consumer-finance conventional wisdom for all renters, not just public housing. Modern reality: it's a useful sanity check but increasingly stretched. In high- cost cities (NYC, SF, LA, Boston, Seattle, DC), 40-50% of renters spend over 30% of income on rent — “rent burdened” in HUD terminology. The 30% rule remains the right TARGET; it's often not the achievable reality.
The calculator takes your gross monthly income (pre-tax) and adds debt-to-income (DTI) sanity checks: total debt payments (rent + minimum credit card payments + auto loans + student loans) should be under 36% of gross income for healthy financial margin. So if you make $5,000/month gross and have $400/month student loans + $300/ month car payment = $700 in non-rent debt, your maximum healthy rent is 36% × $5,000 - $700 = $1,100. The 30% standalone rule would suggest $1,500. The DTI-adjusted calculation gives you the lower (safer) number. Most landlords actually require gross income of 3× monthly rent ($1,500 rent → $4,500/month gross required), which maps to the 30% rule from the landlord's perspective.
Beyond the headline rent, real housing costs include: utilities ($100-300/month typically; varies wildly by region and season), renters insurance ($15-30/month), internet ($50-90/month), parking ($50-300/ month in urban areas), pet fees ($25-100/ month + deposits), commuting costs (if you chose a cheaper apartment further from work, the commute cost partially offsets rent savings). The sticker rent is rarely the all-in cost. Add 10-20% on top of listed rent to estimate true monthly housing budget. For high-cost cities or luxury buildings, can hit 25%+ on top (concierge fees, gym fees, package fees, luxury tax for premium amenities).

Sık Sorulan Sorular
Where does the 30% rule come from?
1969 Brooke Amendment to US Housing Act, which capped public housing tenants' rent at 25% of income (raised to 30% in 1981). The figure became consumer-finance conventional wisdom for ALL renters. Recent research (Harvard Joint Center for Housing Studies, NLIHC) suggests in high-cost cities, the 30% threshold is unrealistic for many income levels — the metric stays useful as an aspirational target.
Why do landlords require 3x rent in income?
Same math from landlord's perspective. 3× rent = rent at 33% of gross income, close to the 30% rule. Landlords screen for tenants who can comfortably afford rent without being rent-burdened (rent-burdened tenants have higher eviction risk). Some landlords flex to 2.5× for strong credit or guarantor situations; some require 4× in high-end / luxury buildings.
What if I'm rent-burdened?
Spending over 30% of income on rent is “rent-burdened” (HUD terminology); over 50% is “severely rent-burdened.” Roughly half of US renters are rent-burdened, mostly in high-cost cities. Strategies: roommate to halve your share, longer commute for cheaper rent (factor in transit costs), employer relocation negotiation, government rent assistance programs, geographic flexibility (move to lower-cost city). Don't accept rent-burden as permanent if avoidable.
What about the 50/30/20 budgeting rule?
Different rule, applies to overall budget. 50% needs (rent + utilities + groceries + insurance + minimum debt), 30% wants (entertainment, dining out, hobbies), 20% savings (emergency fund + retirement). Within the 50% needs allocation, rent typically takes 25-35% of total income. So 30% rent within 50% needs leaves room for utilities, food, etc. The two rules are complementary.
Should I include utilities in the 30%?
Conventionally no — the 30% rule is rent only. Utilities are separate ($100-300/month for typical apartment). Some lease structures bundle utilities (heat, water, internet) into rent, which can shift the math. When comparing apartments, normalize by adding utilities to bundled-utility rent vs separate to get apples-to-apples comparison.
What's the “36% DTI” rule?
Mortgage industry standard: total monthly debt obligations (rent or mortgage + credit card minimums + auto loans + student loans) should not exceed 36% of gross monthly income. Above 36%, lenders consider you over-leveraged. The 30% rent rule is a subset — leaves 6% for other debts. If you have substantial other debt, your safe rent number drops below 30% to keep total DTI under 36%.
