# Cost of poor quality calculator

Poor quality rarely shows up as a single line in the financials: it is spread across scrap, rework, inspection, complaints and expedited freight. Enter what you know, even roughly, and see how much it adds up to per year and which category concentrates it.

- About 6 minutes; leave blank what you do not know (it counts as 0).
- Calculations run in your browser. Amounts are not sent to our servers until you ask for the report.
- Reduction scenarios are illustrative, not promises. We use no industry benchmark figures.
- Currency only changes formatting; there is no exchange-rate conversion.

Inputs: annual amounts and hours in four categories, optional annual revenue, currency MXN or USD:

- Prevention
- Appraisal
- Internal failure
- External failure

Output: total annual cost, breakdown by category, illustrative reduction scenarios.
