Estimate Accepted Units From an Observed Production Yield — Free
A run starts with inputs, but the job ships accepted units. Apply the yield percentage you actually observed to the planned input count and see whether each batch reaches the required output.
The proof surface
Inventory variance audits compare counts and unexplained losses. This register starts from a process yield rate and estimates good units; it does not identify where defects or shrinkage occurred.
Why the flat version breaks
Entering a defect percent as yield
If 8 percent are rejected, the yield is 92 percent.
Using a rate from a different process
Materials, machines and inspection criteria can change the observed yield.
Treating an estimate as inspected stock
Only the actual count and quality check establishes accepted units.
How to work the finished-unit yield register
Enter whole input units such as pieces or assemblies, not weight in one row and count in another.
Use a documented rate from a comparable run. The example percentages are invented and are not a quality benchmark.
The tool floors input units × yield percent ÷ 100 to a whole unit. A thousand units at 92 percent gives an estimate of 920 accepted units.
A row flags below the minimum accepted quantity. Investigate actual quality and process causes separately; do not increase output assumptions to mask defects.
What the finished-unit yield register replaces
| Question | Before | Visible working |
|---|---|---|
| Entering a defect percent as yield | If 8 percent are rejected, the yield is 92 percent. | Choose an observed yield rate |
| Using a rate from a different process | Materials, machines and inspection criteria can change the observed yield. | Estimate finished accepted units |
| Treating an estimate as inspected stock | Only the actual count and quality check establishes accepted units. | Compare with the work order target |
A local arithmetic aid replaces hand calculation, not expert review. No paid AI service is needed.

FIRST-LOAD
Input is processed locally and a draft is saved automatically in this browser profile when storage is available. Reset to sample clears that draft; Pro history has its own clear button. A state link encodes your inputs in its URL: share only non-sensitive rows. Browser history, clipboard and anyone receiving the link may retain it. Optional AI use below leaves this device; it is not required.
Production-planning arithmetic only, not quality assurance, manufacturing safety, product certification or customer acceptance. Follow the work instructions, quality system and safety procedures, and inspect finished goods before shipment. It does not inspect or certify any finished unit.
Data note: Everything runs in this browser tab on the finished-unit yield register: your batch | input units | observed yield percent stays on this device, nothing is uploaded, and the reading is rebuilt only when you press run.
Go deeper: the companion app files the same reading as a bound register page
The article demo above runs without limits. The companion app keeps a local history, exports the rows as CSV, prints the finished-unit yield register reading, and holds your drafts on this device — one free run, then $ 4 one-time for the layer that keeps filing.
The finished-unit yield register reading is complete for free. The optional $4 layer adds print, row CSV and the last five local reading summaries; it does not add hidden answers. Checkout is not configured yet; the article demo remains unlimited.

What this is built on
- Method: the equation is stated next to the result and uses only quantities entered by the reader.
- All sample records are invented examples. No standard, tariff, product rate, schedule or policy is fetched or represented as verified.
- For any threshold or rule, use the current value from the provider, handbook or qualified professional responsible for it.
Before: If 8 percent are rejected, the yield is 92 percent. After: the finished-unit yield register shows the working beside each named row so the reader can change the assumption and inspect the consequence.
Optional AI formatting, not calculation
For this finished-unit yield register, an external AI text tool may help format non-sensitive notes if you already use one. No AI service or account is required: manual entry completes the same free core calculation. Do not paste private or sensitive data. Review every value against the source before using it.
Format my non-sensitive notes for a finished-unit yield register. Return plain rows only: batch | input units | observed yield percent. Preserve supplied quantities exactly. Do not guess missing values; list questions separately. Do not calculate or add advice. I will check every row before pasting into the local tool.
Accepted schema: batch | input units | observed yield percent. No AI response is executed as code.
Walk three labelled examples
First reading. The invented sample Morning run | 1000 | 92 uses minimum accepted units required = 930. The displayed lowest accepted batch estimate is 920.00000 accepted units. Follow the row note back to the measurements and conversion rather than treating the headline number as a recommendation. The sample is deliberately concrete so the reader can reproduce the arithmetic by hand.
Changed assumption. The alternate input Second run | 1000 | 95 produces 950.00000 accepted units for the displayed summary. Compare it with the first reading to see which entered quantity moves the result. In a real plan, change only the assumption that has a traceable source; do not tune a value just to make a row pass.
Boundary case. With Exact target run | 1000 | 93 and the same setting, the worked result is 930.00000 accepted units. This case shows how the arithmetic behaves at a useful edge, not that the underlying process has been measured or verified. Check the boundary statement beside the result and confirm any consequential input with the responsible person before acting.
