Annual gross rent-

Show the math

GRM relates price to the rent a property produces:

GRM = price ÷ annual gross rent

implied value = market GRM × annual gross rent

A lower GRM means more rent per dollar of price. It ignores expenses and vacancy, so it's a fast first screen, pair it with cap rate and cash flow for a fuller picture. All math runs locally in your browser.

What this does

A gross rent multiplier calculator finds the GRM (price divided by annual gross rent) to screen income properties quickly, and estimate value from a market GRM.

How it works

A lower GRM means more rent per dollar of price. Multiplying a market GRM by a property’s annual gross rent estimates its value.

GRM = price ÷ annual gross rent

How to use it

  1. Enter the price and annual gross rent.
  2. Read the GRM.
  3. Enter a market GRM to estimate value.
  4. Compare against similar properties.

Understanding your result

GRM ignores operating expenses, vacancy, and financing, so two properties with the same GRM can perform very differently. Pair it with cap rate and cash flow.

Example

A $240,000 property renting for $24,000 a year has a GRM of 10.
