QC-CALC SPC review
A Windows desktop SPC tool for charting, capability analysis, and manual Gage R&R.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
QC-CALC SPC is Prolink Software’s statistical process control reporting product for manufacturing quality teams. It is aimed at small, mid-market, and enterprise organizations that want desktop SPC charting, capability statistics, and manual Gage R&R workflows. The Windows desktop product works with QC-CALC data files and forms part of Prolink’s Control solution alongside QC-Mobile and QC-Alert for viewing charts, reports, and alerts.
Its focus is analysis and reporting rather than automated collection: data maintenance is manual, and the published features do not list integrations. Data View and Interactive Analysis support reviewing quality data, while the report designer lets teams create or edit report templates. Capability statistics include Cpk and Ppk, and users can set up and report on Gage R&R studies manually. This combination suits teams whose process can accommodate manual data handling; those seeking listed integrations or automated collection should consider alternatives.
The product is offered as QC-CALC SPC 4.3. Prolink says the previous QC-CALC SPC line was merged with Enterprise Report Scheduler, with higher-tier functionality now included in QC-CALC SPC Pro. The current product page directs buyers to contact Prolink for a quote, so published plan-by-plan pricing is not available. Prolink also lists a free download or trial, without specifying its duration or whether a card is required. Support channels include tickets and documentation. Choose QC-CALC SPC for desktop charting, analysis, and manual reporting; look elsewhere if automated data collection is central to your workflow.
