Construction Job Cost & Margin Calculator

Why this matters
Many contractors underprice jobs, fail to recover overhead, or lose margin through weak change-order discipline. A job can look profitable until hidden labor burden, equipment usage, callbacks, or overhead are included.
What you'll figure out
