Frequently asked questions
What is a change order?
A change order is a written amendment to the original construction contract that documents added scope, deleted scope, time impacts, and the resulting price change.
Can a change order reduce the contract amount?
Yes. Enter negative labor hours or a negative material value to issue a credit or remove work from the original agreement.
Should the owner sign every change order?
Yes. Signed approval prevents scope disputes and keeps your billing trail clean if the client questions price or schedule later.
How are overhead and profit applied here?
This calculator applies overhead to direct costs first, then applies profit to the direct-cost-plus-overhead subtotal. That mirrors a common contractor markup method.
Can I save this as a PDF?
Yes. Click the Print / Save PDF button and choose your browser's Save as PDF option to create a shareable document instantly.
