Estimate defect exposure
Use product-specific sample findings, supplier history, or a clearly labeled planning range instead of a generic defect assumption.
Quick Answer
What does this calculator do?
A quality cost calculator estimates the expected financial effect of defects and a proposed inspection or control. Enter quantity, unit cost, expected defect rate, rework or refund cost, replacement logistics, inspection cost, and expected defect-cost reduction. The model compares quality loss before and after the control and shows the effective unit cost.
Primary outputExpected quality loss and effective unit cost
Control testInspection cost versus avoided loss
Best evidenceSamples, prior orders, defect severity
Important limitExpected value cannot predict one order

Methodology
How to use the china sourcing quality cost calculator
The calculator is deliberately transparent: it organizes buyer inputs, shows the resulting logic, and identifies where professional confirmation is still required.
Build cost per defect
Include the product value, rework or refund handling, replacement logistics, and any other direct cost that follows a defective unit.
Describe the control
Enter the inspection or prevention cost and a conservative estimate of how much expected defect cost it can prevent or contain.
Compare scenarios
Run low, base, and high defect-rate cases. Inspecting a safety-critical product is not only an expected-value decision, so consider severity separately.
Interpretation
How to read the result
Use the output to compare scenarios and prepare better questions, not to turn uncertain assumptions into false precision.
Quality changes the real unit cost
Expected defects, rework, replacement, returns, delays, and customer support can turn a low factory price into a higher effective cost per saleable unit.
Inspection has a break-even threshold
The model estimates the defect-cost reduction required to recover the entered inspection cost. A result below that threshold does not capture brand, safety, or compliance risk.
Prevention and detection differ
Inspection can detect or contain issues; it does not automatically correct process capability. Clear specifications, approved samples, supplier controls, and corrective action address different parts of the risk.
Evidence Checklist
Improve the inputs before making a decision
Stronger inputs make the tool more useful. Replace placeholders with dated documents, comparable quotations, test results, and provider confirmations.
Define defects before calculating
Separate critical, major, and minor defects, and describe objective checks. A single blended defect rate may hide a low-frequency problem with high severity.
Use total failure cost
Add replacement freight, refunds, marketplace penalties, rework labor, disposal, customer support, and lost product value when those costs are reasonably estimable.
Update after every evidence point
Replace planning assumptions with sample findings, inspection reports, corrective-action results, and actual post-sale data as the product moves from launch to repeat orders.

Frequently Asked Questions
China Sourcing Quality Cost Calculator questions
Concise answers to the questions buyers should settle before relying on a planning result.
It is the cost associated with failures, rework, replacements, refunds, complaints, delays, and controls. The relevant components depend on the product and sales channel.
Use sample findings, comparable product history, supplier process evidence, and a scenario range. Clearly label the result as uncertain until production evidence exists.
No. Sampling inspection can detect some problems and support shipment decisions, but it cannot inspect every characteristic of every unit or replace process control.
Consider replacement freight, customer handling, return shipping, disposal, repacking, and channel-specific service costs that occur because a defective unit reached the buyer.
Yes. Safety, compliance, customer harm, platform penalties, and brand damage may justify controls even when a narrow expected-cost calculation does not.
This tool models financial exposure. The AQL tool helps plan a sample-size reference and detection probability. They answer different questions and can be used together.
