Rent Affordability Calculator

Check whether a rent fits your budget using gross income, monthly expenses, and the common 30% housing guideline. This is an estimate for planning—not financial or rental advice.

Rent Affordability Calculator

Calculate how much rent you can comfortably afford based on your income and expenses

Income Information

The 30% rule in practice

Many housing counselors suggest spending roughly 30% or less of gross income on rent. At 25% or below, you may have more room for savings and unexpected bills. Above 35%, rent can strain day-to-day finances unless other costs are very low or income is stable and rising.

Location matters: market rents in some cities push households above 30% without other options. Use this calculator to see your numbers, then weigh commute costs, utilities, debt payments, and emergency savings—not the headline rent alone.

How This Calculator Works

1

Enter income and rent

Provide gross monthly income and the rent amount you want to check.

2

Subtract other bills

Add monthly expenses outside of rent to see what is left after housing.

3

Compare to the guideline

See recommended max rent, percent of income, and a simple status label.

About Rent Affordability Calculator

Compare your desired rent to a percentage-based cap and to what is left after other monthly expenses. Status labels use rent as a share of income: up to 30% comfortable, 31–40% moderate, above 40% stretched.

Comfortable

Rent is about 30% of gross income or less in this tool’s labels.

Moderate

Rent is roughly 31–40% of income— workable but tighter.

Stretched

Rent exceeds about 40% of income— consider lower housing or higher income.

3

5

Review results

Pro Tips

  • In expensive cities, many renters exceed 30%—know the trade-off to savings and emergencies
  • Include utilities, parking, and renters insurance in your housing number when they are separate
  • Roommates or a longer commute can lower rent without changing income
  • Aim to keep an emergency fund even if rent fits the guideline
  • Re-run the calculator when income or expenses change

Frequently Asked Questions

How does this calculator work?
Enter your gross monthly income, desired rent, other monthly expenses, and a rent guideline percentage (30% by default). The tool shows a recommended maximum rent (income × percentage), rent as a share of income, money left after rent and expenses, and a simple comfortable / moderate / stretched status.
What is the 30% rule?
A common rule of thumb says housing costs should stay at or below about 30% of gross monthly income. It is a starting point, not a law—high-cost cities, debt loads, and savings goals may mean you need a lower share or a different budget split.
Should I use gross or net income?
This tool uses gross (pre-tax) income for the percentage guideline, which matches how many housing counselors describe the 30% rule. For a tighter view, include taxes and other deductions inside your “total monthly expenses” field.
What expenses should I include besides rent?
Include recurring non-housing costs: loan payments, insurance, groceries, transportation, subscriptions, childcare, and savings you commit to each month. The more complete your expense total, the more realistic your “remaining income” figure.
Does this include utilities or renters insurance?
Only if you add them to your desired rent figure or monthly expenses. Some leases bundle utilities; others do not. Factor parking, pet fees, and renters insurance into your housing budget separately if needed.
Is this financial advice?
No. This is a simple budgeting estimate. Landlords, lenders, and local programs may use different criteria. Speak with a housing counselor or financial advisor for decisions that affect your lease or long-term finances.
