What is a GRM calculator?
A GRM (gross rent multiplier) calculator gives you a one-number screen for rental properties. It is deliberately simple — price relative to rent — which makes it perfect for quickly ranking a list of deals before deeper analysis.
How to calculate GRM
- GRM = property price ÷ annual gross rent
- Price = GRM × annual gross rent
- Rent = property price ÷ GRM
Use GRM as a first filter
Because GRM ignores costs, always follow up with expense-aware tools: the cap rate calculator for return on value, the rental yield calculator for gross and net yield, and the rental property ROI calculator for the full deal.
Frequently asked questions
What is the gross rent multiplier (GRM)?
GRM is a property's price divided by its annual gross rent. A GRM of 12.5 means the price is 12.5 times the yearly rent. It is a fast screening ratio for comparing rental properties.
What is a good GRM?
Lower is generally better because you pay less per dollar of rent, but a good GRM depends entirely on the local market. Typical ranges run from roughly 4 to 12; compare only within the same area and property type.
What are the limitations of GRM?
GRM ignores operating expenses, vacancy, taxes and financing, so two properties with the same GRM can have very different profitability. Use it to shortlist, then analyse with cap rate and cash flow.
How do I estimate price from GRM?
Switch to price mode: price = GRM × annual gross rent. At a GRM of 12.5 and $40,000 annual rent, the implied price is $500,000.
