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.
The Calculation. Once you have your non-productive time figure, divide it by the total hours you pay for and multiply by 100. The result is a percentage. For example, if you pay for 100,000 hours but determine that 20,000 hours are spent unproductively, divide 20,000 by 100,000. The result is .2.Multiply by 100 and you see that 20 percent of your employee's time is spent away from productive activities.You could also say you have 80 percent manpower utilization.he result is .2.
