Contractor Change Order Calculator
Calculate labor, materials, markup, rush fees, deposit, and total price for added contractor work.
Calculate added workPrice more than materials
Added work often affects schedule, setup, procurement, cleanup, and coordination. Include labor and markup, not only material cost.
Use deposits for risk
A deposit can protect cash flow when added work requires materials or schedule disruption. Keep the terms clear and written.
