In this study, the Monte Carlo Simulation method is used in mortgage-backed security asset pool calculations. By simulating different combinations of input variables affecting the mortgage-backed securities asset pool, the future earnings, the total amount of interest, and the minimum and maximum values of the amount of total interest to be distributed are estimated. Six different scenarios were used in the assessment of the asset pool. At the end of the simulation obtained for the scenarios, the minimum, and maximum earnings, total amount of interest and total amounts to be distributed obtained from the asset pool that have been estimated. In conclusion, the Monte Carlo Simulation method is effective in evaluating the mortgage-backed securities asset pool.
