This method uses the Percent Over Last Year formula to multiply each forecast period by the specified percentage increase or decrease.
To forecast demand, this method requires the number of periods for the best fit plus one year of sales history.
Most of the women's fashions during the 1940s were designed with the same squared shoulders, small waist, and skirt above the knee.
Do-it-yourself home fashions were encouraged, and women were educated on how to conserve material or update older dresses to the latest fashions.
This method might be useful in budgeting to simulate the affect of a specified growth rate or when sales history has a significant seasonal component. For example, specify 110 in the processing option to increase the previous year's sales history data by 10 percent.
Required sales history: One year for calculating the forecast, plus the number of time periods that are required for evaluating the forecast performance (periods of best fit) that you specify.
The forecasts include detail information at the item level and higher level information about a branch or the company as a whole.
Depending on the selection of processing options and on trends and patterns in the sales data, some forecasting methods perform better than others for a given historical data set.
The Calculated Percent Over Last Year formula multiplies sales data from the previous year by a factor that is calculated by the system, and then it projects that result for the next year.
This method might be useful in projecting the affect of extending the recent growth rate for a product into the next year while preserving a seasonal pattern that is present in sales history.
A forecasting method that is appropriate for one product might not be appropriate for another product.
