How to calculate construction schedule variance
This calculator finds construction schedule variance by comparing planned progress against actual progress.
How the calculation works
Schedule variance = Actual progress − Planned progress. A positive result means ahead of schedule; negative means behind.
Example
Planned to be 60% complete by this point, but actually 52% complete: Schedule variance = 52 − 60 = −8 percentage points, meaning the project is behind schedule.

Pro Tips for Construction Schedule Variance
- Track schedule variance regularly (weekly or biweekly) to catch schedule slippage early enough to take corrective action.
- Consider tracking variance by phase or trade in addition to overall project variance, to pinpoint exactly where delays are occurring.
Common Construction Schedule Variance Mistakes to Avoid
- Only checking schedule variance at major milestones rather than regularly, which can let a small delay compound into a serious one before it's caught.
