Gross rent multiplier calculator.

GRM is the quick-and-dirty screen: price divided by gross annual rent. It ignores expenses, so it’s no substitute for a cap rate — but it’s a fast first filter to compare listings. Enter any two; get the third.

Gross rent multiplier
GRM = price ÷ gross annual rental income. It uses gross rent, not NOI, so it ignores vacancy and operating expenses — two properties with the same GRM can have very different true returns. Use it to screen and rank quickly, then confirm the winners with a cap rate and full underwriting.
