Private and public higher education institutions have had the problem of financial un-sustainability in recent years. United Kingdom and European Union have instituted programs to work on financial sustainability of higher education. To achieve financial sustainability of higher education, institutions need to maintain or increase internally-generated funds that are regular, without future compromises. The paper establishes the legitimacy for future work needed for the variables to pursue sustainable growth. The study was designed to explore theories behind financial sustainability and established possible correlation between the sustainable growth rate and contributing factors that are sustaining the financing of higher education institutions. Quantitative research methodology was use for the research design with instrument on higher educational institutions across the globe. Results opened an important opportunity for discussion on financial sustainability in higher educational institutions. The outcome states that the predictive model is key to financial sustainability for higher educational institutions.
