Elements of the Productivity Ratio. The labor productivity ratio, in its simplest form, looks like this: output/input. Simply divide the amount of output you're getting by the amount of work you're putting into it. This requires you to assign numbers to both input and output so that you get a meaningful figure.
When you calculate productivity using the labor productivity method, your outputs will change based on the industry. Sales: To measure sales productivity, you should measure a variety of additional outputs, like the number of new accounts opened, the number of calls made, and the volume of sales in dollars.
