Days On Market Formula

The following formula is used to calculate the days on market for a given property.

D = (E - S) / 86400000 - O

Variables:

  • D is the days on market
  • E is the end UTC calendar timestamp in milliseconds
  • S is the listing-start UTC calendar timestamp in milliseconds; O is the number of excluded off-market days

Subtract the listing-start UTC calendar timestamp from the end timestamp, divide by 86,400,000, and subtract the entered excluded days. The listing date is day zero. Actual MLS status, relisting and cumulative-DOM rules may differ.

What is Days On Market?

Days on market (DOM) is a metric used in the real estate industry to indicate the number of days a property has been listed for sale on the market. It is a key indicator of the property’s marketability and can influence the perceived value of the property. DOM needs local market and listing context; it does not by itself establish a property’s price, desirability or value. Real estate agents and sellers often use DOM to gauge the effectiveness of their pricing strategy and marketing efforts.
