Savings mobilization is important for rural households in Uganda. This study looked at household net savings deposits in Savings and credit cooperatives (SACCO's) from individual's passbooks. Net savings were then measured as the difference between deposits and withdrawals. Weighted least squares were used to determine the factors influencing net deposits. Results indicate that deposits decreased with increase in distance to the SACCO, education levels, wealth, trade activities, and having secondary school dependants. Deposits increased with income, access to credit. SACCO's are well suited for poor households in terms of products and services offered. There was a higher propensity to save out of transitory income.
