How to use it
- Enter your monthly take-home pay, the amount that actually lands in your account.
- Add a second income if you will share the lease with a partner or roommate.
- Choose the share of income you want to spend on housing. The 30% rule is the usual starting point.
- Open the extra section to subtract debt payments and utilities you pay on top of rent.
The 30% rule and where it comes from
The common advice is to keep rent at or below 30% of gross income. The figure comes from US housing policy: households spending more than 30% of income on housing are officially counted as cost burdened, and above 50% as severely cost burdened. It is a screening number, not a law, and it says nothing about your debts or your city.
Housing budget = Monthly income × Share ÷ 100
Rent you can afford = Housing budget − Debt payments − Utilities
This calculator applies the share to take-home pay rather than gross pay, which is stricter and closer to what you can really spend.
Worked example
You take home $4,500 a month and pick 30%. That gives a housing budget of $1,350. You pay $350 a month on a car loan and expect $150 of utilities, so the rent you can afford is 1,350 − 350 − 150 = $850. After rent, the car loan and utilities, you still have $3,150 for everything else.
What landlords check
Your budget is one thing; qualifying is another. Many US landlords ask for gross monthly income of at least three times the rent, or annual income of 40 times the monthly rent. On a $1,500 apartment that means roughly $4,500 a month or $60,000 a year before tax. Expect a credit check, proof of income such as pay stubs or an offer letter, and sometimes a guarantor if you are a student or new to the country.
Costs that come with the lease
- Security deposit: often one month's rent, refundable, with state limits on the maximum and on how fast it must be returned.
- First and last month: some markets ask for both up front.
- Application and broker fees: common in tight markets like New York.
- Renters insurance: frequently required, and usually inexpensive.
- Utilities: ask which ones are included. Heat and water are sometimes bundled, electricity rarely is.
- Parking, pets and storage: monthly add-ons that quietly change the real rent.
When a different share makes sense
In expensive metros, many renters spend 35% to 40% and cut elsewhere. That can work if you have no debt, stable income and low commuting costs, but it leaves less room for emergencies. If you carry student loans or a car payment, dropping to 25% is safer. The 50/30/20 approach is a useful cross-check: about half your take-home pay for needs including rent, 30% for wants and 20% for saving and extra debt payments.
Before you sign
Add up the first month's total cash: deposit, first month's rent, any broker fee and moving costs. Check whether rent increases are capped in your city, how much notice the landlord must give, and what the lease says about breaking it early. Then compare the leftover figure from this calculator with your actual spending for a month. If the number feels tight on paper, it will be tighter in practice.

Frequently asked questions
How much rent can I afford on a $50,000 salary?
At roughly $3,400 take-home a month and a 30% share, about $1,000 a month before debts and utilities. Your own tax rate and debts change this.
Is the 30% rule based on gross or net income?
The official measure uses gross income. This calculator uses take-home pay, which gives a more cautious figure.
What is the 3x rent rule?
Many landlords require gross monthly income of at least three times the rent, or 40 times the monthly rent per year.
Should utilities count toward the 30%?
Many budgeting guides include them in housing costs. Enter them here so they come out of the same budget.
What if I spend more than 30% on rent?
It is common in expensive cities. Keep an emergency fund and watch debt payments, since less room is left for surprises.
