Rent Calculator

What this rent calculator does

This calculator turns a gross income and a list of monthly debt payments into a rent range. It reports two ceilings — a comfortable rent and a maximum affordable rent — plus the one-third-of-income limit that many landlords apply when they screen applications.

The result is a planning number, not an approval. Landlords weigh credit history, rental history, savings, and the local market as well as income.

How to use this calculator

1. Enter your pre-tax income.
2. Choose whether that income is per year or per month.
3. Enter the total of your other monthly debt payments: car loans, student loans, credit cards, and similar obligations.
4. Click Calculate.

The default example is an $80,000 annual income with no other debt. The comfortable rent is $1,866.67 per month, the maximum affordable rent is $2,400 per month, and one third of gross income is $2,222.22.

Rent affordability formulas

Monthly gross income = Annual income / 12  (or the monthly income you enter)
Maximum affordable rent = 36% × Monthly gross income − Monthly debt
Comfortable rent = 28% × Monthly gross income − Monthly debt
One-third limit = Monthly gross income / 3

Every result is floored at zero, so a large debt load never produces a negative rent target.

What the results mean

• Maximum affordable rent: the rent that pushes housing costs to 36% of gross income. Above this level, lenders and landlords generally see the budget as stretched.
• Comfortable rent: the rent that holds housing at 28% of gross income and leaves room for savings and irregular costs.
• One-third limit: the ceiling many landlords use when they require rent to be no more than one third of gross income.
• Income shares: the percentage of gross monthly income each rent target consumes.

Assumptions and limitations

The calculator assumes income is stable and that the debt payments you enter are the full recurring obligation. It does not include utilities, renters insurance, parking, pet rent, application fees, or a security deposit, all of which raise the real cost of renting. The 28% and 36% thresholds are rules of thumb; a budget can support a higher or lower share depending on childcare, medical costs, commuting, and savings goals.

Frequently asked questions

Should I use gross or take-home income?

This calculator uses gross income because that is what landlords and lenders compare against. Budgeting from take-home pay is safer for your own planning, because taxes and payroll deductions are already removed.

What counts as monthly debt?

Recurring obligations with a minimum payment: auto loans, student loans, personal loans, credit card minimums, and child support. Do not include groceries, utilities, or subscriptions, which belong in the rent budget rather than the debt figure.

Why is the recommended rent lower than the maximum?

The maximum is a ceiling, not a target. At 36% of gross income, a single unexpected expense can tip a budget into deficit. The 28% figure leaves a buffer for savings and emergencies.

Does a higher income always mean I can afford more rent?

No. The ratio is a starting point. Someone with a high income but large medical costs or dependents may be better served by a lower share, while someone with few obligations can often carry a higher one.
