How this calculator works:

Each change order cost = (Labor Hours ร— Hourly Rate + Materials Cost) ร— (1 + Markup%) + Admin Overhead. The "money left on the table" figure uses the industry statistic that 65% of verbal change orders go unbilled (source). This is your real cost of not having a documentation system.
