As a pioneer in the microfinance (MF) area, Bangladesh is experiencing a high rate of diffusion. This growth phenomenon of the MF industry is indicating the urgency of conducting a customer satisfaction survey. This study attempted to investigate the satisfaction level of MF customers through cluster random sampling in Bangladesh. While analysing more than 550 respondent’s data, this study found that 68% were satisfied with the services of MFIs. Fifteen major factors had been identified as significant from the regression result. Some of them are faith on recording, mobile money transfer, interest on loan and interest on savings. This study also applied structural equation modelling (SEM) to develop a path diagram which revealed that product category influenced customer satisfaction more than human resource capabilities and physical category.
