As international development partners reduce funding for family planning (FP) programs, the need to estimate the financial resources devoted to FP is becoming increasingly important both at all levels. This cross-sectional assessment examined the FP financing sources, agents, and expenditures in two counties of Kenya for fiscal years 2010/2011 and 2011/2012 to guide local decision-making on financial allocations. Data were collected through a participatory process. This involved stakeholder interviews, review of financial records and service statistics, and a survey of facilities offering FP services. Financing sources and agents were identified, and source amounts calculated. Types of FP provider organizations and the amounts spent by expenditure categories were identified. Overall, five financing sources and seven agents for FP were identified. Total two-year expenditures were KSh 307.8 M (US$ 3.62 M). The government's share of funding rose from 12% to 21% over the two years (p=0.029). In 2010/2011, the largest expense categories were administration, commodities, and labor; however, spending on commodities increased by 47% (p=0.042). This study provides local managers with FP financing and expenditure information for use in budget allocation decision-making. These analyses can be done routinely and replicated in other local counties or countries in a context of devolution. (Afr J Reprod Health 2017; 21[4]: 24-32).
