The list price of a real estate property represents the seller's asking price. This is the figure the sellers hope to get for the sale of their property. Most buyers will attempt to achieve a lower price. Through negotiation, a final sale price is achieved, which is likely lower than the original asking price. The difference between the asking price and the sale price is expressed as a ratio, which represents the percentage of the asking price at which the property actually sold.

Get the original asking price, or list price, and the final sale price for the property.

Divide the sale price by the asking price. As an example, if a property was listed at $200,000, but sold for $180,000, then the result of the calculation would be 0.90.

Multiply this figure by 100 to convert it into percentage format. In the example, the sale price to list price ratio would be 90 percent.
