A CMA Calculator helps real estate agents, buyers, and sellers determine a property’s fair market value by comparing it to recently sold similar homes in the same area. Short for Comparative Market Analysis, a CMA is the most widely used method in residential real estate to estimate what a property should sell or list for without waiting on a formal appraisal.
Our free comparative market analysis calculator takes your subject property details such as size, bedrooms, bathrooms, and age, along with up to three comparable sales, and instantly calculates an estimated CMA value, suggested list price, and average price per square foot.

What Is a CMA in Real Estate?
A Comparative Market Analysis (CMA) is a method used to estimate the current market value of a residential property. It works by analyzing the sale prices of similar homes, known as comparable properties or “comps,” that have recently sold near the subject property.
Unlike an appraisal, which is a formal valuation conducted by a licensed professional, a CMA is typically prepared by a real estate agent as part of a listing presentation or purchase negotiation.
- Square footage: Larger homes generally sell for more, but price per sq ft varies
- Bedrooms and bathrooms: Strong influence on buyer demand
- Property age: May require condition-based adjustments
- Distance: Closer comps give more reliable results
- Market trend: Reflects whether the market is rising or falling
How to Use This CMA Calculator
- Enter subject property details including size, beds, baths, and age
- Add up to three comparable sales (price, size, distance, features)
- Apply market trend adjustment if needed
- Click calculate to get estimated CMA value and suggested price
How Is CMA Value Calculated?
The calculator uses an adjusted comparable sales method:
Price Per Square Foot (per comp):
Comp Sale Price ÷ Comp Square Footage
Adjusted Comparable Value:
Price Per Sq Ft × Subject Property Square Footage
Estimated CMA Value:
Average of all adjusted comparable values
Example Calculation
- Comparable 1: $410,000 ÷ 2,000 sq ft = $205.00/sq ft → Adjusted: $444,500
- Comparable 2: $438,000 ÷ 2,200 sq ft = $199.09/sq ft → Adjusted: $409,791
- Comparable 3: $452,000 ÷ 2,300 sq ft = $196.52/sq ft → Adjusted: $388,846
Average Adjusted Comparable Value: $414,379
