PROBLEM TO BE SOLVED: To provide the commission calculation system of an investment trust capable of easily preparing the calculation formula of a commission based on an explanation sentence for describing the calculation method of the commission of the investment trust. SOLUTION: A calculation formula pattern retrieval part 101 retrieves a calculation formula pattern composed of a word for featuring the commission calculation method from the explanation sentence of the commission calculation method accompanying the investment trust and extracts the word present in front or at the back of the retrieved word in the explanation sentence. When the word extracted by the calculation formula pattern retrieval part 101 belongs to a variable pattern composed of the word used in front or at the back of a part where the word included in the calculation formula pattern is used in the explanation sentence of the commission calculation method accompanying the investment trust, a variable pattern retrieval part 102 registers the word. A commission calculation part 103 reads the data of the possessed property of the investment trust pertinent to the word registered by the variable pattern retrieval part 102 from a possessed property storage device 115, substitutes them in the calculation formula corresponding to the calculation formula pattern and calculates the commission. |
