Comparing estimated and actual labor is useful only when both describe the same scope and operations.

Comparing estimated and actual labor is useful only when both describe the same scope and operations. Preserve the original estimate, then identify approved changes, rework, and missing entries before interpreting the variance. A larger total is a starting point for investigation.

## Build a fair comparison

- Compare the same job, phase, and labor-hour definition.
- Separate approved additional scope from original work.
- Check incomplete, overlapping, or misassigned time entries.
- Review material readiness and instructions alongside the recorded effort.

## Worked example

A hypothetical assembly estimate is 80 hours and recorded effort is 92. The variance is 12 hours, or 15% of the estimate. If eight hours belong to an approved addition, the unexplained original-scope difference is four hours, not twelve.

## Improve the next estimate

Record what caused the remaining difference and whether it is likely to recur. Change an estimating assumption only when the evidence supports it.

## How Millbase can help your shop

### Bring job-cost reviews back to the recorded work

Use [Millbase project tracking](https://millbase.ca/#projects) to keep a cabinet job and its sub-projects together, then compare estimates with recorded labour and material costs. [Insights and reports](https://millbase.ca/#insights) help the team inspect the people and workstations behind a total and export supported results for the next review.

Ask the [Millbase AI agent](https://millbase.ca/#how-it-works) a question grounded in your workspace records. For example: *“Compare this project’s estimated and actual labour, then break the logged hours down by workstation.”* You can select a project or worker, ask follow-up questions, and request [supported reports and CSV exports](https://millbase.ca/#insights).

Check the date range, job scope, and recorded inputs before changing a quote. Keep the accounting treatment of overhead, tax, and revenue in the appropriate financial process; a shop-floor cost breakdown is only as complete as the inputs recorded.

## Frequently asked questions

### Should estimates be updated during production?

Maintain a current forecast, but preserve the original baseline. Otherwise the final review cannot show what changed.

### Does a labor overrun prove low productivity?

No. Scope, missing material, rework, training, and inaccurate estimates can all contribute. Review the context before drawing that conclusion.
