27 Apr 2026 EAC (Estimate at Completion): The One Forecast Every Contractor Needs
Why EAC belongs at the center of job control
Every contractor has financial statements. Every contractor has job cost reports. But the number that often matters most in a Monthly Job Review is neither of those.
It is EAC — Estimate at Completion.
EAC tells leadership where a job is likely to finish if current conditions continue. In other words, it is the best current estimate of total job cost at the end of the project.
That makes it one of the most valuable early‑warning tools in construction.
EAC in plain English
The formula is simple:
EAC = Cost to Date + Forecast Cost to Complete
What teams struggle with is rarely the math. The struggle is discipline: keeping forecast assumptions up to date as field realities change.
At a minimum, EAC assumptions should reflect:
-
- Labor productivity trends
- Unresolved scope and change work
- Buyout gaps and commitments
- Subcontractor performance
- Schedule pressure and inefficiency
That is why EAC should never be treated as a static accounting number. It is a management number.
What a good EAC discussion looks like
A good EAC discussion is not complicated. It should answer three questions:
-
- What is the current EAC?
- What changed since last month (by how much)?
- Why did it change (name 1–3 drivers)?
If no one can explain the movement, leadership does not yet have a usable forecast.
Common EAC mistakes to avoid
-
- Treating EAC like a “plug” (backing into the number you want)
- Leaving old assumptions in place after production reality changes
- Ignoring commitments and known exposures
- Forecasting in the meeting instead of before it
Where EAC fits in the Monthly Job Review packet
EAC is best understood in context. In the Toolkit, EAC is supported by the Summary Sheet (job story) and Job Cost Review (forecast validation). It is also influenced by change orders, commitments, and productivity, where those are major drivers.
Take the next step
If your team cannot explain where a job is likely to land, it is very difficult to proactively manage margins. That is why EAC is not just an accounting concept—it is one of the clearest management tools in the Monthly Job Review process.
