About our Calculators

We maintain a proprietary database of over 4,000 case studies, research papers, government reports, books, and anything we put our eyeballs on that has to do with workplace strategies that impact human and organizational agility and performance. Specifically, we focus on strategies that promote:

  • Flexible work (mobile work, telecommuting, telework)
  • Activity-based working
  • Wellness and well-being
  • Employee Engagement

We have worked with some of the nation’s largest and smallest agile work employers and their employees, the advocates and the naysayers, the top researchers, leaders of successful programs, and even venture capitalists who have invested in companies that use the agile work model.

One of the things we found missing in the research, was any real analysis of what companies, employees, and communities could save, in real dollars, through agile work and other strategies, so we set out to fix that.

Using the latest Census data, and assumptions from dozens of government and private sector sources, we developed a number of models to quantify how various workplace changes can impact the economy, the environment, and society in general. They have been used by hundreds of company and community leaders throughout the U.S. and Canada and cited in a wide variety of publications.

Some of our calculators include:

Our Mobile Work Savings Calculator™—developed to estimate the people, planet, and profit impact of telework—was chosen by the U.S. General Accountability Office for use throughout government stating it was comprehensive and based on solid research.

Details about the 125 customizable assumptions and 600 calculations that power it are provided below to demonstrate the rigor that goes into the development of all of our models.

Mobile Work Savings Calculator™: The Assumptions

As skeptics at heart and our approach has been to base our assumptions on highly credible research and to err on the side of being too conservative, rather than too aggressive. A list of the primary sources behind the assumptions in our Mobile Work Savings Calculator™™ is provided below. Additional details about our methodology is available in our white papers.

A few of the assumptions behind our model are worth mentioning specifically because they tend to draw the most questions:

1)  Our standard remote work model assumes half-time remote work – which is roughly the national average for those who work remotely on a regular basis. It seems to represent the ‘sweet spot’ that mitigates the employer and employee concerns about issues such as company culture and employee loneliness yet still offers substantial employee, employer, and environmental benefits.

2) Regarding who can work remotely, we assume 45% of the population hold jobs that are compatible. That’s based on an update we did of a very thorough study conducted by Mathews & Williams, a couple of PhDs, who went through the Bureau of Labor (BLS) Statistics data and evaluated the jobs that met their criteria for remote work compatibility. Only 4 categories of jobs made the cut: professional, technical support, administrative support and a fraction of sales jobs. Management level jobs, even within those categories, were not considered eligible.

Unfortunately, that study was done more than 5 years ago – ancient in terms of the current state of technology, so we revised Matthews & Williams assumptions to reflect the existing rate of participation among those categories that they excluded.

3) Recognizing that you can’t take the kids to school on just the days you head to the office, we relied on a synthesis of a number of respected studies by groups including the Reason Foundation, the Air Quality Board, and private company surveys to estimate how much driving is reduced on remote work days. We used BLS data to estimate how much extra utility use might cost while working at home.

4) Not everyone wants to, can, or should work remotely. Our estimate for those who want to is based on a synthesis of studies by WorldatWork, the federal government, and private company surveys and actual experiences.
