Price divided by annual gross rent. Read it as years of gross rent, because that is literally what it is.

The figures
The asking price, the contract price, or the value being tested.
Scheduled rent at full occupancy, before any deduction. Say whether other income is in this figure; the market does not agree, and a multiplier quoted on a different gross is a different number.
Computed from the other two. Pick a different figure above to type this one.
What the multiplier cannot see
Vacancy, credit loss and operating expenses, net of other income. This is measured against gross rent, which makes it larger than an operating expense ratio quoted against effective gross income. It is used only for the comparison below; it does not touch the multiplier.

At this load the same rent produces $600,000 of NOI, so the screen that reads 10x is a 6.00% going-in cap rate. Change the load and watch the cap rate move while the multiplier does not.

The same multiplier, different buildings

Every row below is the same price and the same gross rent. Only the share of that rent which survives vacancy and expenses changes, and the going-in yield moves 3.00 points across the range. That is the whole case against pricing anything on a multiplier: it cannot see the column that decides the answer.

$10,000,000 against $1,000,000 of annual gross rent, a 10x multiplier held constant.

A gross rent multiplier ignores expenses, vacancy, capital structure, lease terms and capital needs completely. Two buildings can trade at the same multiplier and produce completely different net operating income, which is what the table above shows in dollars. Use it to sort a list quickly and to notice an outlier; do not use it to price a building, and never compare one across property types or lease structures.

Everything above is computed in your browser. Nothing you type is sent to Altyst or to the site hosting this calculator, and this frame sets no cookie. It is arithmetic on the figures you entered, not investment or lending advice.

A multiplier sorts a list. Pricing a building takes the expense stack behind it, the debt it can carry, and every year of the hold. Altyst reads the documents and builds that.
