    This paper presents a gas turbine engine parametric performance analysis. The aim of this work is to determine the influence of the compressor pressure ratio of the exergetic costs of all energy streams, assuming the exhaust gases as a waste or a residue. If the exhaust gases are considered as a waste, its exergetic cost is zero; and if it is treated as residue, the exergetic cost is no null. The highest exergetic cos t is associated to the exhaust gases stream of the exit of the combustion chamber. This cost is mainly affected by treating the exhaust gases as a waste or as a residue. For the optimum compressor pressure ratio related to the maximum thermal efficiency of 40.05, the exergetic cost of the stream at the exit of the combustion chamber is about 787618 kW, if the exhaust gases are assumed as a waste. If they are considered as a residue the mentioned exergetic cost presents an increment of 15.66% for the same compressor pressure ratio.
