Employee commuting – using the distance based method

*Note that this is related to employees traveling from/to the office, not employees traveling to customers/conferences. The latter would be deemed ‘business travel’.

What is most straightforward here is to think about:

  • Share of folks working in-office (eg out of organisations' 352 headcount, is it a 100% or 50%)

  • Avg days of those people in, actually going into office. Eg perhaps Organisation AZ has an office attendance policy that stipulates 3 office days.

    • We’ve had users cross-reference badge-ins, but not sure if such advanced insights are available to your organisation

  • Avg round trip distance people have to the office (you would normally ask that in a survey), but you can probably make an estimated guess based on asking the HR colleague, eg do people live within 5/10/20/50 mile radius on avg

  • In the US on average 95% of cars are gasoline with only 5% diesel (source EIA), so would assume all cars use gasoline/petrol (same word!)

  • Example: 50% of headcount goes in (176#), 3 days per week office policy, assuming 48 work weeks per year hence 144 trips, average round trip distance is 15 miles, hence inserting the below:

Home working - using the average-based method

This should be aligned to your assumptions for commuting, i.e. if you assume 3-day per week office policy, then you would take 2-days WFH as the average for your calculations here. How to get to the total hours of working from home (the final input our calculator would ask for):

  • 50% of company have WFH 2 days per week, 50% 5 days.

  • Assuming average work day is 8 hours, 48 work weeks per year

  • So, the total number of hours WFH are:

    • 50%*352*2*8*48 = 135,168

    • 50%*352*5*8*48 = 337,920

    • Total = 473088 hours
