This study investigates the technical and profit efficiency of commercial banks in Pakistan. Data Envelopment Analysis is used as a preferred methodology to accurately determine profit and technical efficiency. The constant return to scale model is employed and Excel Solver is used to give scores which highlights the efficiency differences across three ownership categories. The study identifies loans and interest income as outputs and deposits and interest expense as the inputs to measure the technical efficiency. It identifies loan loss provision as a factor causing deviation in profit efficiency from the technical efficiency. Our study suggests that the profit efficiency improves over the years and technical efficiency is also rising in 2009. Large banks are relatively more efficient than small banks and private banks have better efficiency scores. The results can be generalized for commercial banks across different ownership structures and size but this generalization doesn’t spread across the Islamic banking sector due to the choice of DMUs which include no Islamic bank. According to the policy maker’s perspective, the study establishes the economic importance of banking industry in the country.
