What is Estimate to Complete (ETC)?
Estimate to Complete answers the forward-looking question: "from this point, how much more money do we need to finish?" It's simply the full forecast (EAC) minus what's already spent (AC).
Sponsors care about ETC more than any other EVM number — sunk costs are gone; ETC is the check they still have to write.
Formula
ETC = EAC − AC
Worked example
EAC = $120,500 and you\'ve spent $42,000 so far. ETC = 120,500 − 42,000 = $78,500 — the money still needed to finish from today.
