How much rent can you afford?
Start with your income, then subtract the commitments that will not disappear when you move: loan payments, money you set aside each month, and the ordinary costs of living. What remains is the rent you can pay without stretching every paycheck.
The common shortcut is the 30% rule, which caps housing at 30% of gross income. It is a useful starting point, but it ignores your actual obligations. This calculator applies the rule and then checks it against your take-home budget, so the number you see is the lower of the two.
How to use this calculator
- Pick your income type. Enter annual pre-tax pay, or switch to monthly take-home if you already know what lands in your account.
- Add monthly debts. Car, student, and personal loans plus minimum card payments.
- Set a savings goal. The amount you want to keep moving into savings or an emergency fund every month.
- List other expenses. Utilities, groceries, transport, subscriptions, and anything else that recurs.
Results update as you type. Open Assumptions if your tax rate or target rent percentage differs from the defaults, and use the copy link control to share the exact scenario.
What the 30% rule actually means
The guideline says rent should stay at or below 30% of gross monthly income, the amount before taxes. It is the ratio property managers most often look at when they review an application, so it is both a budget target and a rough approval signal.
| Annual income | Monthly gross | Rent at 30% |
|---|---|---|
| $40,000 | $3,333 | $1,000 |
| $60,000 | $5,000 | $1,500 |
| $80,000 | $6,667 | $2,000 |
| $100,000 | $8,333 | $2,500 |
| $150,000 | $12,500 | $3,750 |
Gross income is not the same as spendable income. Taxes and deductions take a chunk before rent is due, which is why a household earning $75,000 may find 30% comfortable in one city and tight in another.
When 30% does not fit your city
In markets like New York, San Francisco, or Boston, renters routinely pay 35% to 50% of gross income. Paying more is sometimes the only way to stay close to work, but it shifts risk onto the rest of your budget. If you go above the guideline, keep the rest of your fixed costs low and protect an emergency fund.
A landlord may also approve a rent that feels uncomfortable. Approval is based on their risk, not your savings plan, so treat the calculator result as your ceiling rather than a target.
Ways to keep rent inside your budget
- Share the unit - One roommate can cut both rent and utilities by 30% to 50%, which is usually the fastest way to move from stretched to comfortable.
- Negotiate the lease - Longer terms, a larger upfront payment, or moving in during a slower winter month can all justify a lower rate.
- Look one neighborhood out - A short commute extension often cuts rent meaningfully without changing your daily routine much.
- Trim recurring costs first - Subscriptions, delivery, and parking are easier to cut than rent, and they compound every month.
- Save before you sign - Three months of rent in reserve turns a surprise repair or a slow month into an inconvenience instead of a crisis.
Frequently asked questions
What is the 30% rule for rent?
It is a budgeting guideline that says housing should cost no more than 30% of your gross monthly income, before taxes. Landlords often use the same ratio when they screen applications, so it doubles as a rough approval benchmark as well as a personal budget target.
Is rent affordability based on gross or take-home pay?
The 30% rule uses gross pay, which is the number before taxes and deductions. Your actual budget is tighter because rent comes out of take-home pay. That is why this calculator shows both: the guideline, and what is left after your debts, savings, and living expenses.
What counts as monthly debt here?
Any recurring payment tied to money you borrowed: car loans, student loans, personal loans, and minimum credit card payments. Do not include utilities, groceries, or insurance that you already list under other expenses, otherwise you will count the same dollar twice.
Does the 30% rule include utilities?
No. The guideline covers rent only. Utilities, renters insurance, parking, and internet are separate costs, so enter them under other expenses. If your landlord bundles utilities into the rent, use the total bundled amount as your rent figure instead.
What if I live in an expensive city?
In high-cost markets many renters spend 35% to 50% of gross income on housing. It can be the only practical option, but it leaves less room for savings and emergencies. If you go above 30%, cut other categories first and keep a three-month cushion before signing.
How much should I save before signing a lease?
Plan for the first month, a security deposit, and often a broker or application fee, then keep at least three months of rent in reserve. Moving costs, furniture, and utility deposits add up quickly, and an emergency fund is what keeps a surprise repair from becoming a missed payment.
This calculator produces estimates for planning only. Actual affordability depends on your complete financial picture, local rental market, and the terms of the lease. Confirm numbers with a financial advisor before committing.
