How do I figure out the expected market value to open a store to compete against Macy's? Here is the data I have?

trade area population 851,490, trade area households 284,807, and average annual household income $91,938. The estimated value for all the Macys organization as of July 2022 is $4.8B. There are 570 Macys in the whole United States, 42 stores in the state of Florida. Apologies I submitted this question twice by mistake.
