A method of analyzing and comparing changes in costs between a first and a second time period includes a first step of receiving cost data for the first time period and cost data for the second time period, a second step of calculating data representing a change in cost from the first time period to the second time period, based on a difference between the cost data for the first time period and the cost data for the second time period, and a third step of outputting the data representing the change in cost from the first time period to the second time period. The cost data represents a cost of a commodity purchased or to be purchased during a given time period. The cost data may also be compared with comparative data.
