Abstract
Many problems arising in the mathematics of finance involve identical money flows at regular time intervals and are solved by appropriate valuation at a focal date or by setting up an equation of value. This paper shows how such problems can be viewed as special cases of a certain class of first-order difference equations. To illustrate the annuity models, we draw tables to compare the reinvestment of benefit from a fixed deposit and the usual simple interest method. We also compare the cost efficiency between Amortisation and Sinking fund loan repayment as prevalent in financial institutions.
Keywords: Annuity, Amortisation, Sinking Fund, Present and Future Value Annuity, Maturity date and Redemption value.
