PROBLEM TO BE SOLVED: To visually understand a calculator of mutual relationship of values of constituting factors used to calculate a labor rate by disposing a fill-in column of a value of a constituent and a calculation symbol of a first computing equation near a fill-in column of a value of a constituent of a second computing equation. SOLUTION: A fill-in column 6 is to fill in a laborage direct cost, and a fill-in column 7 is to fill in a laborage indirect cost. A value to be filled in the column 7 is calculated according to a computing equation indicating multiplication and division symbols with the values filled in fill-in columns 8 to 10. Thus, since symbols indicating to fill in the same values are printed near the columns 6, 11, a plurality of computing equations for calculating a labor rate and values of constituents used in the equations can be visually confirmed. Thus, in the case of its simulation, a standard of how the value of the constituent is altered can be decided.
