What is the 3x Rent Calculator?

Check the income you need to meet a 3x rent requirement. To use the 3x Rent Calculator, enter monthly rent, your monthly gross income, multiplier; it returns required monthly income, required annual income, rent as share of your income, and shows them instantly as you type.

Measuring a rental property

Rental investors compare properties with a few standard ratios. Net operating income (NOI) is rent minus operating costs, before the mortgage. The cap rate divides NOI by price. Cash-on-cash return divides yearly cash flow by the cash you actually invested. Each answers a different question, so use more than one.

Costs that are easy to forget

Vacancy, repairs, property management, insurance, property tax and capital replacements (roof, furnace) reduce the rent you actually keep. Use conservative figures for each and test a bad year, not only a good one. The rental property calculator puts the whole picture in one place.

Rent from the tenant’s side

Landlords often ask for income of about three times the rent; check it with the 3x rent calculator. For moves, partial months and increases, use the prorated rent calculator and the rent increase calculator.

How to use the 3x Rent Calculator

  1. Enter your numbers. Start with Monthly rent ($), Your monthly gross income ($), Multiplier. Use figures from a lender quote or your tax bill where you have them, and keep the term and rate realistic. Fields marked optional can stay at zero.
  2. Read the result. The highlighted box gives the Required monthly income, and the cards below show Required annual income, Rent as share of your income. Tables and charts break it down further.
  3. Test other scenarios. Results update as you type. Change one value at a time to see what drives the answer, and press Reset to go back to the defaults.

Formula and how it works

Required income = monthly rent × 3 (per month) or × 36 (per year).

Example with real numbers

Here is the 3x Rent Calculator using the default values shown in the calculator above:

Your monthly gross income ($)5,200

Results

Required monthly income$5,400.00
Required annual income$64,800.00
Rent as share of your income34.62%

With these inputs the calculator returns Required monthly income: $5,400.00. Change any value in the calculator to see how the result moves.

What if you change one input?

Sensitivity check: raising Monthly rent ($) from 1,800 to 2,160 (about 20% higher) and leaving everything else as in the example above changes the results like this:

Required monthly income$5,400.00$6,480.00+20%
Required annual income$64,800.00$77,760.00+20%

The input that moves the result most is the one to check twice. Change it in the calculator above to test your own case.

Frequently asked questions

Why do landlords ask for 3x rent?

It ensures that rent is about one third of gross income.

What is included in a monthly mortgage payment?

Principal and interest, plus property tax, homeowners insurance, PMI if your down payment is under 20%, and HOA fees if they apply.

How much house can I afford?

A common rule is to keep housing costs under about 28% of gross income and total debt under 36%. The House Affordability Calculator applies those limits to your numbers.
