Comps price calculator

Enter the comparable sales from your CMA. You get each comp's price per square foot, the outliers flagged, the median, and a list price range with the math shown.

How the calculator prices from comps

1. Price per square foot for each comp: sale price ÷ square feet.
2. Outliers out. With four or more comps, a comp whose price per square foot is more than 20% away from the median of the other comps is left out, and the calculator says which one and why.
3. Median, not average. The median of the comps that remain. One odd sale can move an average a lot and the median barely at all.
4. Indicated value: the listing's square feet × the median, and × the lowest and highest price per square foot, so you see the whole band.
5. Suggested range: about 4% wide. It is centered on the median value for a home that is about the same as the comps, and moved halfway toward the low or high end if it is clearly worse or better. It never goes outside the low–high band.

List-to-sale ratio and days on market

If you add each comp's original list price, the calculator shows the median list-to-sale ratio (sale price ÷ list price) and where offers are likely to land for your range. Days on market shows how fast the comps sold.

Why there are no dollar adjustments

Adding or subtracting a fixed amount for a garage or a bathroom looks precise but is mostly guesswork. Here you only say which way the listing differs from the comps. Put numbers on specific features only when you have local paired-sales data or an appraiser's view.

When the seller wants more

If you enter the seller's target, you see how far above the median value and above the top of the range it sits, in dollars and percent. That number is easier to discuss than an opinion.

This calculator does arithmetic on the comps you enter. It is not an appraisal and not legal or financial advice. Choose comps that are truly comparable: recent, nearby, similar size, age and type.
