Rent Affordability Calculator
Find the rent you can afford from yearly income using the 30 percent rule.
What it does
Rent is usually the largest single line in a household budget, so knowing what fits before you sign a lease matters. The common planning rule holds rent at no more than 30 percent of gross income, leaving the rest for food, transport, debts, savings, and everything else.
The tool above turns your yearly income into a safe monthly rent ceiling, plus the yearly rent total and the cash left after rent each month. Enter your gross income before tax and read the result.
Thirty percent is a ceiling, not a target. If you carry student loans, car payments, or credit card debt, your real affordable rent sits lower. Lenders and landlords also look at total debt alongside income when they screen applications.
Hot rental markets push many households past 30 percent, while calm markets let you aim near 25 percent. The math stays the same either way; only your comfort and local prices change.
How to use
- Enter your gross yearly income before tax.
- Read the max monthly rent first: that is 30 percent of income divided by 12.
- Read annual rent to see the yearly housing cost at that ceiling.
- Read leftover monthly to see what remains after rent for all other costs.
- Lower the income figure to test a smaller budget, or raise it to see a higher ceiling.
Formula
- yearly income
- Gross pay before tax, in dollars per year.
- max monthly rent
- Ceiling rent payment in dollars per month.
- annual rent
- Total rent paid in a year at the ceiling.
- leftover
- Monthly income after rent, in dollars.
The tool uses gross income, not take home pay. Taxes, insurance, and retirement contributions come out before rent, so your real room for rent is smaller than the gross number suggests.
Worked example
Example: $60,000 yearly income
Yearly gross income 60,000, 30 percent rent rule.
- Monthly income: 60,000 / 12 = $5,000.00.
- Max rent: 5,000 x 0.30 = $1,500.00 per month.
- Annual rent: 1,500 x 12 = $18,000.00 per year.
- Leftover: 5,000 - 1,500 = $3,500.00 per month.
- Tool shows max rent $1,500.00/mo, annual rent $18,000.00/yr, leftover $3,500.00/mo.
Reference table
| Yearly income | Max monthly rent | Annual rent |
|---|---|---|
| $30,000 | $750.00 | $9,000.00 |
| $45,000 | $1,125.00 | $13,500.00 |
| $60,000 | $1,500.00 | $18,000.00 |
| $75,000 | $1,875.00 | $22,500.00 |
| $90,000 | $2,250.00 | $27,000.00 |
Limits
- The 30 percent rule is a planning guide, not a legal limit or a guarantee.
- Gross income is used; taxes and deductions lower what you actually receive.
- Debts such as student loans and car payments shrink the rent that fits.
- Local rental markets can force higher shares or make lower shares easy.
Common mistakes
- Using take home pay instead of gross income, which overstates what fits.
- Forgetting utilities, renter's insurance, and parking that sit outside rent.
- Ignoring debts that compete with rent for the same income.
- Treating the ceiling as a target rather than an upper limit.
- Not checking lease rules and local price levels before applying.

Questions
What is the 30 percent rent rule?
Spend no more than 30 percent of gross yearly income on rent. On $60,000 that is $1,500.00 a month.
Does 30 percent include utilities?
No. The rule covers base rent only; utilities, insurance, and parking are extra.
Can I afford more than 30 percent?
Some do in expensive markets, but it leaves less for savings, debt, and emergencies. Treat 30 percent as a ceiling.
Should I use gross or net income?
Gross income before tax, since the rule is framed on gross pay. Your take home is what actually lands in your account.
What if I have debts?
Subtract debt payments first. The rent that fits is lower when student loans, car loans, or credit cards already claim income.
Do landlords use this rule?
Many screen with income-to-rent ratios near 30 percent, though each landlord sets their own standard.
