This study investigated the growth status of SACCOS before and during the implementation of the JK Billions in Tanzania mainland. Linear regression models using enter method predicted varying relationships. Before the fund came into effect i.e. 2005, the study results showed that saving was well predicted by women than did their counterpart men. However, as the fund got underway, neither women nor men were significant predictors of savings. In both models i.e. before and after the implementation of the fund, savings amount appeared to predict well the level of loans issued to members. This study concluded that men and women have different saving preferences as members of savings and credit cooperative societies. Moreover, loans are also determined by the levels of savings. The government must limit its efforts to technical development and facility development of member-based financial institutions instead of pumping credit.
