How it is calculated: Cost to complete = outstanding commitments plus the uncommitted forecast allowance. Forecast final cost = costs recognised to date plus cost to complete.

Use the result as a commercial check, not a substitute for the project records.

The quality of the result depends on the figures entered. Keep actual costs, outstanding commitments, variation values and remaining allowances current so the forecast reflects the job as it stands today.
