Rent Affordability Calculator

A common starting point is the 30% rule: try to keep rent at or below 30% of your monthly take-home pay. Real life is messier though. Debt payments, transportation, and savings goals all eat into that number. Our calculator factors in your actual bills so the answer reflects your situation, not just a rule of thumb.

Many landlords ask that your gross monthly income be at least three times the monthly rent. So for $1,500 rent, they want to see at least $4,500 in monthly income. Some landlords use 2.5x, some use 3.5x, and some count co-signers. It varies. The rule is about approval odds, not affordability.

For affordability planning, use take-home (after taxes and deductions). That's the money you actually have to spend. Landlords usually look at gross income for the 3x rule. The calculator uses take-home by default and lets you add gross income as an optional input for the 3x check.

A safe target is the upfront move-out cost plus 3 months of essential expenses. Upfront costs typically include security deposit, first month's rent (sometimes last month's too), moving, furniture, and basic supplies. Three months of expenses is your buffer if income takes a hit early on.

It's a reasonable ceiling in most U.S. markets, but it isn't universal. In high-cost cities, people routinely spend 35 to 50% on rent. That can be manageable if other bills are low and there's no debt. In lower-cost areas, 20 to 25% leaves much more breathing room. Treat 30% as a starting line, not a finish line.

Plan for: security deposit (commonly 1 month's rent, though state laws and landlord practices vary, with some states allowing up to 2 to 3 months), first month's rent, sometimes last month's rent, application fees, moving truck or movers, basic furniture, kitchen and cleaning supplies, an initial grocery run, and utility setup deposits. For a modest first apartment in a mid-cost market, $3,000 to $6,000 is a common total.

Maybe. It depends on the size of the payments, not just the existence of the debt. A $400/month student loan changes your rent budget meaningfully. The calculator includes debt payments in your monthly bills, so the leftover number tells you whether the math works after debt is served.

Aim for at least 20% of take-home left over after rent and recurring bills. That cushion covers savings, irregular expenses (car repairs, medical), and small emergencies. Less than 10% left over is a sign the budget is too tight.

No. This is a planning tool to help you estimate affordability and move-out costs. It isn't a substitute for advice from a financial planner, and it can't guarantee a landlord will approve you. Real-world deposits, fees, and approval rules vary.
