The increase in formal financial access is recognized as vital for improving household income and driving economic growth. However, despite the rise in formal financial access from 75.5% in 2019 to 83.7% in 2021 in Kenya, household income generation remained low, suggesting that financial access alone may not be the primary issue. To delve deeper into the factors influencing this adverse trend, this research focused on the role of saving literacy among SACCO members in Machakos County, Kenya, drawing on the lifecycle saving theory. Employing a descriptive research design, the study targeted 3,050 registered SACCO members from which a sample of 217 respondents was selected through stratified sampling and purposive sampling. The study data was collected using self-administered structured questionnaire and analyzed through descriptive statistics (percentages and means) as well as inferential statistics (regression and correlation). The findings revealed that saving literacy had a significant positive role ((β = 0.46, p < 0.05), on household income generation, underscoring its importance in boosting income among SACCO members. As a result, the study recommends the implementation of comprehensive saving literacy programs by SACCOs and relevant stakeholders to maximize their impact on income generation. This should be coupled with efforts to promote access to financial resources and provide ongoing support and guidance to members, ultimately fostering improved household income.
