Quarterly Studies in Banking Management and Islamic Banking

Abstract In recent years, the banking industry has undergone drastic changes. Banks are trying to be more cost-effective and profitable to stay competitive.  Achieving profit requires banking services to be produced and provided at a minimum cost, and revenues to be maximized.  The purpose of this study is to simulate the bank cost model to improve, control, and adjust costs and increase profitability Dynamic simulation of research using Vensim software has been performed in a period of twenty years, from 2011 to 2031 in an Iranian commercial bank. To do that, first, the main indices influencing the cost model based on the real operation were extracted; then the indices were applied to the final research model. The model simulated based on bank performance can be used as a decision tool for bank managers to reduce costs and examine the impact of relevant variables in this area.
