Quality Assurance Statistical Sampling Plan Calculator

Streamline Quality Control with Statistical Sampling

Quality assurance doesn't mean inspecting every single unit—it means inspecting the right number with statistical confidence. This Quality Assurance Statistical Sampling Plan Calculator helps manufacturing teams, quality control managers, and production supervisors determine optimal sample sizes for batch inspections without oversampling or risking quality issues.

Built for Manufacturing Workflows

Whether you're running incoming material inspections, in-process quality checks, or final product audits, this calculator gives you a defensible sampling plan based on established statistical principles. Input your batch size, select your desired confidence level (90%, 95%, or 99%), define your acceptable margin of error, and get instant sample size recommendations.

From Calculation to Action

Paperform's calculation engine handles the statistical formulas automatically, so your QA team can focus on the inspection itself rather than spreadsheet work. Use conditional logic to show different inspection protocols based on calculated risk levels, and embed the form directly into your quality management system or intranet.

Once you've determined your sampling plan, use Stepper to automate what happens next—create inspection work orders, assign tasks to QA technicians, update your ERP or quality management software, and trigger non-conformance workflows when defects exceed acceptable levels. Everything stays connected without manual handoffs.

Secure, Compliant and Scalable

Paperform is SOC 2 Type II certified and trusted by manufacturers worldwide for sensitive production data. Set up role-based access so only authorized quality personnel can generate sampling plans, and keep audit trails of every calculation for compliance and continuous improvement initiatives.
