What this calculator measures

This is a business estimate, not an accounting or legal calculation. It values unpaid extra hours using the project’s original effective hourly rate.

  • Original effective rate = project price ÷ planned hours.
  • Unbilled work value = extra unpaid hours × original effective rate.
  • Rate erosion compares the original rate with the rate after those extra hours are absorbed.
  • Annual exposure assumes the same pattern repeats across the number of similar projects you entered.
