The additional expense is the crucial issue in the implementation of a now legislated K to12 educational reforms. The cost of education especially in the additional two (2) years of Senior High School was a valid concern and entails a serious study. The Department of Education admitted that there are additional indirect costs, but they argued that government agencies are collaborating to provide programs that will enable everyone to access quality education, especially to those with lesser means. Despite such developments, the “how much” is the cost of education remains to be a problematic situation. Tis quantitative study provided such answers utilizing cost estimate, descriptive survey, with cost analysis in education as its framework. Southeastern Mindanao, Philippines is the location of the study where students, parents, and administrators of both the private and public schools were the respondents. The Filipino family income whose expense primarily intended for food and other basic needs is not enough if another two years is added to the educational system. Correct estimated government subsidy for the cost of additional two years is imperative to augment the potential family income deficit.
