Is your rent too high? Enter your income and expenses to see your rent-to-income ratio, debt-to-income ratio, 30% rule status, and exactly what income you'd need to afford your current rent comfortably.
The traditional guideline says rent should be no more than 30% of gross monthly income, but that rule was created decades ago and doesn't account for debt, utilities, or regional cost differences. This calculator gives you a more complete affordability picture using multiple financial benchmarks so you can see exactly where you stand.
Multiple benchmarks exist for determining whether rent is affordable. No single rule fits everyone, so it helps to check several at once:
The most well-known guideline: spend no more than 30% of gross monthly income on rent. This originated from the 1969 Brooke Amendment in U.S. public housing law. It's a useful starting point but doesn't account for debt, taxes, or regional cost differences. In high-cost cities, many renters spend 40–50% and still live comfortably if they earn high incomes.
Popularized by Senator Elizabeth Warren, this rule allocates: 50% of after-tax income to needs (rent, utilities, groceries, minimum debt payments), 30% to wants (dining, entertainment, subscriptions), and 20% to savings and extra debt payments. Rent plus utilities should ideally fall within the 50% "needs" bucket alongside other essentials.
Lenders use DTI to assess lending risk, but it's equally useful for renters. Front-end DTI is rent alone; back-end DTI includes all debts. A back-end DTI below 36% is generally considered healthy. Above 43% signals financial stress. Many landlords also check DTI when screening applicants, requiring gross income 3× rent.
The 30% rule assumes you live in an average-cost area. In San Francisco or New York, spending 35–40% on rent is often unavoidable even for well-paid professionals. In rural Midwest markets, 20–25% may be easily achievable. Regional context matters — compare your rent to local median rents, not just your income percentage.
The standard guideline is 30% of gross income. For a $5,000/month gross income, that's $1,500. However, if you have significant other debt, a lower ratio (20–25%) leaves more room for debt payments and savings. In high-cost cities, 35% is common and may be unavoidable.
The 30% rule traditionally uses gross (pre-tax) income. Some financial advisors prefer net income, which gives a clearer picture of what you actually take home. If you calculate based on net income, a reasonable target is 25–35% of take-home pay.
Using the 30% rule: $2,000 / 0.30 = $6,667/month gross, or about $80,000/year. If you have other debt payments, you'll need more. Many landlords require income of 3× rent, which also works out to $6,000/month or $72,000/year for $2,000 rent.
Yes, many people do — especially in expensive cities. The key is whether you can still cover other essentials, save for emergencies, and service debt. If rent is 35% but you have no car payment and minimal debt, you may be fine. If rent is 35% plus high debt payments, you're likely stretched thin.
Most landlords require gross monthly income to be at least 3 times the monthly rent (the "3x rule"), which implies rent is about 33% of income. They also typically run a credit check and verify income via pay stubs or bank statements. Some landlords in competitive markets require 40× monthly rent in annual income.
