The purpose of this paper is to obtain basic data and a calculation method of the Life Cycle Cost for the rental office building management. At first, a cash out flow model for 20 years, which is drawn up based on the data obtained from the maintenance records at a certain rental office building, is presented. Then a new idea of LCC definition is derived. The necessory expenses for the tax calculation of the construction cost is the depriciation cost and that of the sustaining costs is themselves. The difference of the tax reduction effect of these are taken into consederation. Therefore, such LCC is in proportion with a minus coefficient to the profit which is the difference between the Net Present Value and the initial investment. Using the cash out flow model, the relationship between LCC and the expected profit, and the influence of the LCC estimation margin to the risk which is brought by the uncertainty of the income and expenditures estimation is analyzed.
