Valuation Details

The firm Business Brokerage used a cash flow Valuation methodology to determine the Purchase Price of the business.

Cash flow is the sum of business net income plus any owner perks and any non-onward expenses. For this valuation, we used the 2-year cash flow average making the business price much more favorable to the buyer.

The formula used is as follows:


2-Yr. Avg. Cash Flow    x  Prescribed Multiple   =   Fair Market Value


With this information, the computation is as follows:

 $1,705,827                   x                3.55              =      $6,055,686

Growth Opportunities

Growth opportunities include pursuing more projects in the mechanical side and especially general contracting, structural and steel erection, which currently accounts for only 9% of the business. There are also opportunities to scale business through marketing and advertising as less than 20% of their current business is new work.
