Two ways to find your number
Quick estimate takes 30% of your monthly income before tax, then subtracts any housing bills you add. Hourly pay assumes your weekly hours continue for 52 weeks. The 25% figure is a lower comparison point.
My actual budget starts with take-home pay and subtracts your other spending, savings, and housing bills. What remains is available for rent. Include all your costs: an omitted bill makes the result too high.
These are planning estimates, not rental approval criteria. Sources: HUD's affordability definition and CFPB's monthly budget worksheet.
