What the rent calculator compares
The result separates gross-income ratio, take-home cash flow and the additional costs that may not appear in advertised base rent.
Rent affordability formulas
The chosen percentage applies to gross monthly income. Other recurring costs are subtracted to show the base rent that fits inside that total.
gross monthly income=annual gross÷12target housing=gross monthly×target%target base rent=target housing−other housing costsWorked $120,000 example
Gross monthly income is $10,000. A 30% target allows $3,000 for total housing; $400 for utilities and other recurring costs leaves $2,600 for base rent.
Understanding the 30% benchmark
HUD explains the historical 30-percent housing-cost burden standard and its limits. It is a broad indicator, not a complete household budget.
Gross ratio versus take-home cash
Landlord screening often references gross income, while bills are paid from take-home income. The calculator shows both views so payroll deductions are not hidden.
Costs to verify before signing
Check utilities, deposits, move-in charges, insurance, parking, pet fees, commuting and renewal terms. Review the lease and local rules directly.
Recurring housing-cost checklist
| Cost | Examples |
|---|---|
| Utilities | Electricity, gas, water, internet |
| Insurance | Renters policy premium |
| Parking and fees | Required space, amenity or service fees |
| Other | Pet rent or recurring building charges |
Frequently asked questions
Should I use gross or take-home income?
The target uses gross income; the cash-flow comparison uses take-home income.
Is 30% a universal rule?
No. It is a broad benchmark with important household and market limitations.
Are utilities part of rent?
They are included as separate recurring housing costs here.
Does this guarantee landlord approval?
No. Screening criteria vary by landlord and jurisdiction.
What if target base rent is negative?
Entered non-rent housing costs already exceed the chosen total target.
Are deposits included?
No. This calculator focuses on recurring monthly costs.
What to keep in mind
The target percentage is a planning input, not an approval rule. Landlords use their own screening, and an affordable budget also depends on taxes, debt, transportation, childcare, savings and local costs.
