A concrete example
Fictional example: a USD 6,000 project with 9 extra hours × USD 100/hour adds USD 900: a 15% project value increase and USD 6,900 revised project value. This excludes tax, expenses, and any risk allowance.
Free tool vs. paid workflow
The free calculator provides numerical estimates only: additional work value, project value increase, and revised project value. AddBriefly adds your chosen schedule impact, fixed English message tones, and a proposed change summary with copy/print.

You already know what the extra work is worth and need to turn that figure into a fee, deadline impact, and client-ready change note.
