A discount system for installment of trade articles and its method is proposed in the present invention. The discount system provides at least a first trade article and a second trade article. When the second consuming end purchases the second trade article after the first consuming end purchases t he first trade article, an accumulative value is added by one to record the number of people who purchase the second trade articles. After that, a processing unit calculates a discount price according to the accumulative value so that the installment payment of the first consuming end is reduced correspondingly. Thereby, the profit of marketing the trade articles for the second consuming end is transferred partially to the first consuming end. In this way, the presen t invention can attract more consumers to purchase the articles.
