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 as reported by Browne et al.

To achieve financial sustainability of higher education, institution needs to increase its internally-generated income or funds, which needs to be flowing on a regular basis for its operation, without compromising the future of its sustainability.
