Here are detailed step-by-step instructions on how to use the Agricultural Trade Multiplier (ATM) calculator to generate open model multipliers.

Step 1-Select your commodities of interest using either the predefined ERS commodity groupings or the commodity selection tree. Note that you cannot make concurrent selections from both the predefined groupings and the
selection tree.

To select from among the predefined groupings (all agricultural exports, farm commodities, all crops, livestock, nonfarm commodities, bulk commodities, and high-value commodities) click the radio button to the left of the grouping of interest. Only one group from the ERS predefined list can be selected.

To instead select from the commodity selection tree, click on the box next to each commodity or commodity group. A check mark (√) will appear next to each selection. At any time, you can click checked boxes to undo selections from the list, thus enabling you to tailor your analysis to a single commodity or any combination thereof.

Once selections have been made from either the predefined groupings or the tree list, click the Next button to proceed to the next step.

Step 2-Select the type of multiplier by clicking the radio buttons corresponding to either the producer or port level of the export process. The producer level includes the activity embodied in the commodity as it leaves the farm gate or manufacturer's door before shipping and handling charges have been added. By definition, both the ERS and user margins for a producer-value multiplier are set to 100 percent for producer and zero for both transportation and wholesale/retail trade. You cannot select new margins for the producer level. If producer-level multipliers suit your needs, select Producer and proceed to step 3.

If you want to input your own trade margins, select Port. Port-value multipliers reflect the value of the commodity as it leaves the farm gate or manufacturer's door and shipping, handling, and storage charges between the farm or manufacturer and the port. The ATM calculator allows you to adjust the producer, transportation, and wholesale/retail margins to your liking. Once you select Port, the calculator will generate a table. Input your margins in the table. The three margins can range from 0 to 100 and must be a whole-integer value. The sum of the three margins must equal 100. Click the Save Margins button to confirm your margins sum to 100, save them for analysis, and proceed to step 3. If your margins do not sum to 100, a warning box will pop up and ask you to correct your entries.

Step 3-Click the Review Results button to create and display your model results table. If you selected more than 10 commodities, the table will be displayed over multiple pages. The number of pages will be noted in the blue bar at the bottom of the table. Click on a page number to display that page in the table.

All tables can be printed and/or downloaded in Microsoft Excel Excel icon (16x16) format.
