Pension funding program is a system which provides money or fund for employees when they are retired on pension. There are many factors that caused an employee is being retired on pension. They are work stoppage, disability, normal retirement, and mortality. The calculation of pension funding program needs an assumption which can be used to predict the amount of salary when somebody is retired. This is commonly called salary function. A salary function was influenced by some factors such as inflation and merit. This study discussed the declining of salary function model based on exponential function. The salary function model was differentiated by age (age-based model) and service (service-based model). Both of these models had been estimated using Levenberg Marquardt method. After that, the model had been used to calculate the amount of Actuarial Liability (AL) and also to calculate the amount of gains and losses used Projected Unit Credit (PUC) and Entry Age Normal (EAN). The result of this case study showed that the most suitable of salary function model was a model based on age (age-based model) that had been applied using Entry Age Normal (EAN) method.
