Rent Affordability Calculator
Compare a housing-cost benchmark with the cash left in your monthly budget, then use the lower rent estimate as a conservative planning ceiling.
Conservative monthly rent ceiling
Budget summary
How to estimate an affordable rent
Enter annual income before taxes, monthly income after taxes and payroll deductions, recurring debt payments, estimated utilities, essential monthly spending, and a savings goal. The example starts with a 30% housing share. Choose Calculate rent limit to compare the two planning views.
The conservative rent ceiling is the lower result. It is a starting point for reviewing listings, not a target you must spend. Leave room for deposits, application fees, moving costs, renter insurance, irregular expenses, and emergencies before committing to a lease.
Gross-income benchmark
The housing-cost benchmark is annual gross income ÷ 12 × target housing percentage. Because HUD housing-cost measures include rent and utilities, the rent-only benchmark subtracts the entered monthly utilities once: housing-cost benchmark − utilities, with a minimum of zero.
HUD commonly describes households spending more than 30% of income on housing costs as cost burdened and more than 50% as severely cost burdened. The percentages are policy measures, not a lease qualification rule, lender standard, local market forecast, or individualized financial advice.
Take-home budget view
The budget ceiling is monthly take-home income − debt − utilities − essential spending − savings goal, with a minimum of zero. This follows the practical structure of a monthly budget: start with income that reaches the household, then reserve cash for recurring obligations and priorities.
Utilities are counted once in this view. The result shows the rent ceiling before utility bills, while the housing share adds rent and utilities together. If the take-home budget is tighter than the gross-income benchmark, the page uses the take-home amount as the conservative ceiling.
What this estimate does not decide
This browser-only V1 accepts one household income and one monthly budget. It does not predict landlord approval, verify income, check credit, search listings, quote utility rates, recommend a property, calculate a security deposit, determine assistance eligibility, or apply local occupancy and screening rules.
Use current bills and realistic spending rather than treating the default example as a recommendation. If monthly obligations exceed take-home income before rent, the budget view returns zero so the shortfall stays visible instead of becoming a negative rent amount.

Frequently asked questions
How much rent can I afford?
This calculator shows two planning views. The gross-income benchmark reserves the selected share of gross income for rent plus utilities. The take-home budget subtracts debt, utilities, essential spending, and a savings goal from monthly take-home income. The lower rent amount is shown as the conservative ceiling.
Why does the calculator ask for both gross and take-home income?
Gross income supports a common housing-cost ratio, while take-home income shows the cash actually available after taxes and payroll deductions. Looking at both can reveal a rent amount that fits one rule but not the rest of the monthly budget.
Are utilities included in the 30% rent rule?
HUD housing-cost measures include rent and utilities. This calculator treats the entered utilities as part of housing cost and subtracts them once when converting a housing-cost benchmark into a rent-only ceiling.
Is 30% a required rent limit?
No. HUD uses more than 30% of income for housing costs as a cost-burden measure and more than 50% as a severe cost-burden measure. Those are general measures, not lease approval rules or a personalized recommendation.
Does this estimate include moving costs, deposits, or renter insurance?
No. Add those costs to your own planning before signing a lease. The calculator models monthly rent, utilities, debt, essential spending, and savings; it does not model deposits, application fees, moving costs, renter insurance, taxes, or local assistance eligibility.
Are my income and budget values saved or uploaded?
No. The calculation runs in this browser. Entered and derived financial values are not placed in the URL, browser storage, cookies, application requests, structured data, or analytics parameters.
