Introduction to GRM
The Gross Rent Multiplier is a simple and effective way to evaluate a property's potential return based on rental income. This metric allows investors to compare multiple properties quickly and easily without complex calculations.
GRM focuses only on the property's purchase price and gross rental income, making it a lightweight tool for preliminary analysis. It's particularly useful when you want to filter potential investment opportunities before doing a deeper dive.
By using this calculator, you can save time and make informed decisions about your property investments. Understanding the Gross Rent Multiplier can significantly improve your real estate strategy.
GRM Formula
The formula for Gross Rent Multiplier is straightforward. You only need two numbers: purchase price and annual gross rental income.
GRM = Property Purchase Price ÷ Annual Gross Rental Income
For example, if a property costs $200,000 and the annual rent is $20,000, then the GRM is:
GRM = 200,000 ÷ 20,000 = 10
This means the property costs 10 times its annual rental income. Lower GRM values generally indicate better investment potential.
Examples of GRM Calculation
Here are some real-world examples showing how to calculate GRM:
- Example 1: Purchase Price $150,000, Annual Rent $15,000 → GRM = 10
- Example 2: Purchase Price $300,000, Annual Rent $25,000 → GRM = 12
- Example 3: Purchase Price $500,000, Annual Rent $50,000 → GRM = 10
- Example 4: Purchase Price $250,000, Annual Rent $20,000 → GRM = 12.5
- Example 5: Purchase Price $100,000, Annual Rent $12,000 → GRM = 8.33

| Property | Purchase Price ($) | Annual Rent ($) | GRM | Location | Property Type | Notes |
|---|---|---|---|---|---|---|
| Property A | 150,000 | 15,000 | 10 | NYC | Residential | High demand area |
| Property B | 200,000 | 20,000 | 10 | LA | Residential | Close to school |
| Property C | 300,000 | 25,000 | 12 | Chicago | Condo | Downtown |

| Property G | 180,000 | 18,000 | 10 | Seattle | Residential | Urban core |
The first table helps you visualize how GRM varies with property price and rental income. Investors can quickly spot opportunities with lower GRM for better cash flow potential.

Investment Tips for GRM
When using Gross Rent Multiplier, consider combining it with cash flow analysis and cap rate for a complete picture. GRM alone doesn't account for expenses like maintenance, taxes, or insurance, so treat it as a first step.
Look for properties with lower GRM in growing markets. A low GRM often indicates potential for better return relative to price. Always check local rental demand and vacancy rates before making a decision.
Use this calculator to run multiple scenarios quickly. Compare properties in the same city, different cities, or neighborhoods to determine where your investment will perform best.
