3x Rent Calculator: How Much Do You Need to Earn to Rent?
The 3x rent calculator helps you apply the 3x monthly rent rule — a guideline that landlords and property managers use to decide whether a tenant can comfortably afford an apartment. The rule says that your total monthly income should be at least three times the monthly rent. The income that counts is your gross income, before taxes and deductions.
The idea behind the rule is simple: if rent takes no more than about a third of what you earn, there is enough left for taxes, utilities, food, transport, debt payments and savings. Use the calculator to find out what 3 times the rent is for any apartment — for example, what 3 times a rent of $1,500 is — or turn the question around and see the highest rent your salary allows.
⚠️ Not every landlord asks for 3x the rent, and the requirement is a screening policy, not a law. Even if your landlord does not check it, the 3x rule is a good way to understand how much income you need to rent comfortably.
What the calculator can do
- Income needed for a rent — enter the monthly rent and get the minimum gross income per year, month, two weeks, week and hour.
- Maximum rent for your income — enter hourly, weekly, biweekly, monthly or annual pay and get the highest rent that passes the rule.
- Do I qualify? — enter both, and see whether you meet the rule, by how much you exceed it or fall short, and what rent your income would allow.
- Other rules — 2.5x, 3.5x, 4x, the New York 40x rule (annual income of 40 times the monthly rent) or your own multiplier, all compared side by side.
- Net pay — if you only know your take-home pay, enter it with your tax rate and the calculator estimates the gross income landlords look at.
- Roommates — the combined income required and each tenant's share when the rent is split equally.
- Price per square foot or square meter — enter the size of the apartment in sq ft (American units) or m² (metric units) to see the rent per unit of area in both systems.
- 20 currencies — US dollar, Russian ruble, euro, pound, yen, yuan and more.
How to calculate 3 times the rent
The formula for the 3 times rent rule is:
where:
- three times rent is the 3x rent — the gross monthly income a tenant is required to have;
- monthly rent is the total monthly rent.
To get the annual figure, multiply by 12: an annual gross income of 36 × monthly rent satisfies the 3x rule. The New York 40x rule is written in annual terms directly: annual income ≥ 40 × monthly rent, which is the same as about 3.33 times the rent per month, or rent of no more than 30% of gross income.
It is that simple! The reverse is just as easy — the highest rent you can afford under the rule is your gross monthly income divided by 3.
How much is 3x the rent?
Here is what 3 times the rent is for some typical monthly rents:
| Monthly rent | 3x rent (monthly income) | Annual income | Hourly, 40 h/week |
|---|---|---|---|
| $1,000 | $3,000 | $36,000 | $17.31 |
| $1,200 | $3,600 | $43,200 | $20.77 |
| $1,500 | $4,500 | $54,000 | $25.97 |
| $2,000 | $6,000 | $72,000 | $34.62 |
| $2,500 | $7,500 | $90,000 | $43.27 |
| $3,000 | $9,000 | $108,000 | $51.93 |
So 3 times a rent of $1,500 is $4,500 per month, or $54,000 per year. The hourly figure assumes 52 weeks of 40 hours (2,080 hours a year) and is rounded up to the cent, because the rule sets a minimum.
Example in reverse: if you earn $60,000 a year, your gross monthly income is $5,000 and the 3x rule allows a rent of up to $5,000 ÷ 3 = $1,666.66 a month (rounded down, because it is a maximum).
Can landlords ask for 3x the rent?
In most places, yes. Landlords may set income requirements as part of tenant screening, as long as they apply the same criteria to every applicant. The 3x rule is the most common one; some landlords ask for 2.5x, others for 3.5x or 4x, and in New York City the usual requirement is the 40x rule. To prove your income you are usually asked for recent pay stubs, a tax return or W-2, an employment offer letter or bank statements.
Some cities and states limit how income can be used. For example, source of income laws in many places forbid refusing tenants because part of their rent is paid by a housing voucher, and some jurisdictions restrict how high the income requirement can be for voucher holders. Check the rules where you rent.
If you do not meet the requirement, you may still be approved with a guarantor or co-signer (in New York guarantors are often asked to earn 80 times the monthly rent per year), a larger security deposit, several months of rent paid upfront, proof of savings, or a roommate whose income is added to yours.
Is the income gross or taxed in the 3x rent calculator?
🔎 So, is 3x rent gross or net? From the formula above, the rule uses gross income — your income before taxes, social security, health insurance and other deductions. That is the number on your offer letter or at the top of your pay stub, not what lands in your bank account.
If you only know your take-home pay, choose Net (take-home) in the calculator and enter your approximate total tax rate. The calculator estimates the gross income as net ÷ (1 − tax rate). For example, a take-home pay of $3,900 a month at a 22% tax rate corresponds to about $3,900 ÷ 0.78 = $5,000 gross.
FAQs
How do I calculate 3 times the rent?
Multiply the monthly rent by 3. For a rent of $1,800 you need a gross monthly income of 3 × $1,800 = $5,400, which is $64,800 a year.
What is 3x the rent of $1,500?
3 × $1,500 = $4,500 per month, or $54,000 per year before taxes.
How much rent can I afford with a $50,000 salary?
$50,000 ÷ 12 = $4,166.67 per month. Divided by 3, the rule allows a rent of up to $1,388.89 a month.
Does the 3x rent rule use gross or net income?
Gross income — the amount before taxes and deductions.
How does the 3x rule work with roommates?
Most landlords add the incomes of all tenants together and compare the total with 3 times the full rent. Some instead ask each roommate to earn 3 times their own share of the rent. The calculator shows both figures.
What is the 40x rent rule?
It is the New York version of the rule: your annual gross income must be at least 40 times the monthly rent. For a $2,500 apartment you need $100,000 a year. It is a little stricter than the 3x rule (36 times the rent per year).
Is the 3x rule the same as the 30% rule?
Almost. The 3x rule means rent is at most one third (33.3%) of gross income; the 30% rule means rent is at most 30% of gross income, which equals about 3.33 times the rent — the same as the 40x rule.
What if I do not make 3 times the rent?
Look for a cheaper apartment, add a roommate, offer a guarantor or co-signer, show savings, or offer a larger deposit or prepaid rent. Some landlords also accept a lower multiple from tenants with an excellent credit history.
