The real margin on a bid priced for 15 percent, when the crew cleans the building at 2,200 square feet an hour and the bid assumed 2,500. On the guide’s example, an 8,000-square-foot dental office cleaned five nights a week, the price drops from $3,675 to $3,380 a month while the crew works the same hours, and about $3,500 a year goes with it. That’s why the calculator starts from production rates you time on your own crews, and why the guide shows you how to run the time study.
From the Lakeside Dental Group example in the guide: a fictional office priced at the calculator’s default costs. Your own numbers will differ.
