What is ETC (estimate to complete)?

    Estimate to complete is the forecast cost of the remaining work, from the reporting date to the end.

    Also written as ETC

    ETC is what the project still needs to spend. Comparing it with the remaining budget shows whether the money left is enough.

    Formula

    ETC = EAC − AC

    Worked example

    A project has a $12 million budget (BAC). At the reporting date, $5.2 million of work was planned (PV), $4.8 million has been earned (EV) and $4.55 million has been spent (AC). ETC = $11.375m − $4.55m = $6.825 million.
