Business Survey Index (BSI) is a business indicator indexed by observing companies' judgments, forecasts, and plans for economic trends. By using a three-point scale of positive, normal, and negative, the formula is based on the difference between the number of positive and negative respondents.
BSI = ((Number of positive respondents- number of negative respondents)/total respondents)*100)+100
