Performance measurement in banking sector is not straight forward because it is difficult to define and measure both inputs and outputs. Further, banks may not be homogenous with respect to the types of output actually produced. In present study 23 financial ratios are computed on which performance is measured. Average composite scores of most of the foreign banks are positive depicting above average performance. In the case of private sector banks some have positive composite scores and some have negative scores. This reveals, some have above average performance and others are not up to the mark. Majority of the public sector banks have negative composite scores resulting in poor performance.
