    The aim of this study is to evaluate the economic and engineering layout carried out on a factory scale LiFePO4 production using the hydrothermal synthesis method. The method used is economic evaluation by calculating gross profit margin (GPM), payback period (PBP), break-even point (BEP), internal rate return (IRR), cumulative net present value (CNPV), return on investment (ROI). , and the profitability index (PI). LiFePO4 was synthesized using precursors FeSO4.H2O, ascorbic acid and H3PO4 and then reacted with LiOH2.2H2O by maintaining the Li: Fe: P molar ratio of 3: 1: 1. The results of GPM and CNPV calculations from the manufacture of industrial scale LiFePO4 show that the payback period (PBP) has increased in the fourth year. LiFePO4 applications on an industrial scale can be used for lithium ion batteries
