58 THE MODEL STOCK PLAN in each department we determine in advance the percentage of our total stock that should be carried in staples, novelties, extra-large and extra-small sizes, related lines, and so on. Now we come to the mechanics of making our plan. How long a time should be covered in the plan must vary with the type of merchandise. If we were selling old-fashioned base- burner stoves, our principal selling period would be merely a couple of months in late autumn, and we should plan to have our stock practically cleared out by, say, the middle of December. On the other hand, we may expect to sell men’s white broadcloth shirts the year round, with a peak of volume beginning in the late spring. Since, however, the principle is the same in either event and an attempt to differentiate may be confusing, let us assume throughout the following explanation that we make our general plans twice yearly, to cover the usual department store periods of six months each, August through January, and February through July. The usual large store’s mer- chandising plans cover, in general, the following forecast figures: 1. Stock, first of period. 2. Purchases for period. 3. Mark-downs. 4. Stock, end of period. 5. Sales for period. 6. Gross profit. 7. Expenses. 8. Merchandise profit. 9. Earned discounts. In the usual practice of the past—mnot in the Model Stock Plan—the six months’ stock and sales plan started with an allotment of capital to each department. This was clearly not the best way. The most profitable way is to build up the stock of the department to the requirements of the Model Stock Plan, which is the way to the greatest total profits. If, then, this stock is too large for the sales that our department can be reasonably sure of, we study still more carefully the amount of stock. Once we are sure of our
