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.
How to Calculate Productivity. The economic health of a country is most often determined by their labor productivity. Labor productivity is a per-hour measurement of generated output on a per-worker basis.In layman's terms, how much work a worker completes in an average hour. In the case of $100,000 produced over 1 month with a combined total man hours of 5,000, the calculation would be: $100,000 / 5,000 = 20$ per hour productivity.
