Abstract

The study examines commercial banks profitability in Tanzania for the period of ten years (2000-2009).The
study used National Microfinance Bank (NMB), National Bank of Commerce (NBC) and CRDB as the case

terms of profitability was established based on return on average asset, net interest income to average bearing
assets and non-interest expenses to average assets. The paper utilized panel secondary data from National bank
of commerce, CRDB and National Microfinance bank in Tanzania for the period of ten years, and the hypothesis
was tested to know whether there is a significant difference in terms of profitability by using ANOVA test.
Finally the regression model was run to see the effects of capital adequacy, liquidity and asset quality on the
profitability of commercial banks. The findings revealed that there is no significant difference on profitability
among the commercial banks, in the context of regression model it has been noted that liquidity and asset quality
has positive impact in profitability with exception to the level of nonperforming loans which has a negative
influence on profitability. Also capital adequacy has shown negative impact on profitability. The study
