Fixture, Gauge & Workholding Management calculator
Fixture Inventory Accuracy Calculator
Fixture inventory accuracy is the percentage of audited fixtures whose recorded location, status and identity match physical reality. Tool crib managers and quality engineers use it to gauge whether the fixture tracking system can be trusted for scheduling, recertification due dates and audits. Low accuracy quietly causes lost production time hunting for fixtures, missed recert dates, and scrap from using the wrong workholding. A cycle-count audit turns that risk into a single number you can manage against a target, the same way warehouses manage SKU accuracy.
What this calculator does
- Calculate fixture inventory accuracy by comparing correctly located, identified, and usable fixtures with the audited fixture population.
- Use it when auditing toolroom records, barcode systems, crib locations, obsolete tooling, missing fixtures, or incorrect storage status.
- It divides correctly recorded fixtures by fixtures audited and multiplies by 100 to get an accuracy rate, then reports the point gap between that rate and your target.
Formula used
- Fixture Inventory Accuracy rate = correctly recorded fixtures ÷ fixtures audited × 100
- Fixture Inventory Accuracy gap to target = fixture inventory accuracy rate - target fixture inventory accuracy
Inputs explained
- Correctly recorded fixtures:
- Fixtures audited:
- Target fixture inventory accuracy:
How to use the result
- Use it after a cycle count or annual tool crib audit to score data integrity and decide whether corrective action is needed.
- Accuracy depends entirely on a representative sample; auditing only easy-to-find fixtures inflates the number and hides the records that are actually wrong.
Current U.S. benchmarks
- The U.S. has 14,378 furniture and related products establishments employing about 355,594 workers (Census County Business Patterns, 2023).
Common questions
- How do you calculate fixture inventory accuracy? Divide correctly recorded fixtures by fixtures audited and multiply by 100. With 286 correct out of 310 audited, accuracy is 92.26%.
- What is a good fixture inventory accuracy? World-class tool crib and inventory operations target 97-99%. The default target of 98% is a reasonable goal; 92.26% leaves a 5.74-point gap that warrants corrective action.
- What does the gap to target mean? It is the difference in percentage points between your measured accuracy and your target. A gap of 5.74 points means you are short of the 98% target and have roughly 18 of 310 records to fix to close it.
- What counts as a correctly recorded fixture? One where the physical fixture matches the system on identity, location and status. If location, calibration status or quantity is wrong, it counts as an error even if the fixture physically exists.
- Fixture inventory accuracy vs cycle count accuracy? They are the same idea applied to fixtures rather than parts. Both measure record-to-reality match from an audit sample; fixture accuracy additionally cares about recert status, which generic part counts ignore.
