This paper is dealing with a business plan for opening a sports hall consisting of six multi functional indoor playgrounds for hiring, located in the western part of the City of Zagreb.

The business idea is to build a venue on this plot that consists of two football fields, two basketball courts and two playgrounds for different sports such as badminton or volleyball. Initial investment is estimated at 819.198 HRK, of which 790.00 HRK will be invested into long term assets, and 29.198 HRK into working capital. Sources of finance consists of the entrepreneur’s equity as high as 369.198 HRK and a bank loan as high as 450.000 HRK. Secondary research involves data and information collected from books, scientific papers, and internet sources, as well as from supporting literature on various school courses. Primary research was carried on using a short questionnaire survey aimed at examining the habits, needs, expectations and financial opportunities of the potential users of the new sports hall.

Based on the business analysis and the assessment of the key performance indicators it was concluded that the project is profitable. Net present value is positive and amounts to 463.102 HRK, profitability index is higher than 1 and amounts 1.57. The payback period, i.e. the length of time required to recover the cost of the investment is 3.85 years. The internal rate of return of 23 % is higher than the average cost of capital of 8.7 %.
