How Much Rent Can You Afford? The 30% Rule and Better Alternatives
October 21, 2026
The best-known guideline for housing affordability is the 30% rule: spend no more than 30% of your gross income on housing. For someone earning $72,000 a year ($6,000 a month), that is $1,800 a month. Many landlords apply a related test: the monthly rent should be no more than one-third of gross monthly income, or equivalently annual income of at least 40 times the monthly rent. A rent of $1,800 would require an annual income of $72,000.
The rule is simple, but it has well-known limitations. It ignores your debts, your location, your savings goals, and whether you are paying taxes at a high rate. It is a starting point, not a verdict.

The 28% rule, used in mortgage underwriting, caps housing at 28% of gross income: $1,680 for a $6,000 monthly income. The 50/30/20 budget allows needs, including housing, utilities, groceries, and transport, to take 50% of after-tax income. With after-tax income of $4,800, needs total $2,400, so rent might be $1,300 to $1,500 once other needs are subtracted. Some advisers suggest a 25% cap for high-cost areas where saving for the future is difficult.
The landlord's 40x rule uses annual income of 40 times the rent: for $1,800 rent, income of $72,000. Some landlords use 3x monthly rent.
| Gross annual income | 30% rule (monthly) | 28% rule (monthly) | 40x income test (max rent) |
|---|---|---|---|
| $48,000 | $1,200 | $1,120 | $1,200 |
| $72,000 | $1,800 | $1,680 | $1,800 |
| $100,000 | $2,500 | $2,333 | $2,500 |
| $150,000 | $3,750 | $3,500 | $3,750 |
Adjust for Your Real Situation
The percentage should shift with your circumstances. If you have student loans or other debt payments, you may need to keep housing closer to 25%. If you live in an expensive city, you might have to pay more than 30% but can offset it with lower transportation costs by living near work. People with high incomes can afford a lower percentage and save more, while those with low incomes may find that 30% leaves too little for food, healthcare, and transport. Government housing programs often consider households 'cost-burdened' above 30% and 'severely cost-burdened' above 50%.
Calculate your take-home pay and test your budget: with $4,800 after tax and $1,800 rent, you have $3,000 left for everything else, 62.5% of take-home.
The Full Cost of Renting
Monthly rent is not the whole bill. Add utilities, renters insurance ($10 to $30 a month), internet, parking, pet fees, and laundry. Initial costs include a security deposit (often one to two months of rent), first month's rent, application fees, and moving costs. A $1,800 apartment could easily cost $2,200 a month all in. Annual rent increases of 3% to 8% are common, so a rent that fits today may stretch you in two years. Compare total costs when choosing between apartments, including commute costs. A cheaper place far from work may cost more once transport and time are included.
Roommates reduce cost: splitting a $2,400 two-bedroom costs each $1,200.
Use the Rules as a Guide, Then Budget
Start with 30% of gross income as a ceiling, 25% as a more comfortable target if you want to save aggressively. Then build a full budget to see if your goals fit: emergency fund, retirement savings, debt payments, and fun. If rent crowds out savings, consider roommates, a smaller place, or a different neighborhood. If you plan to buy a home, remember that the money you spend on rent could instead build savings for a down payment, so a lower rent can speed up that goal.
