OCR Human Review Staffing Calculator
Touchless rate is the number everyone quotes, but headcount depends on what happens to the rest. This calculator converts your volume, touchless rate and handling times into reviewer hours and FTE.
Your numbers
All invoices or records entering capture.
Share that posts with no human touch.
Average time to check and correct.
Share of exceptions needing research.
Your results
Planning estimate only. Real workloads vary with document mix, seasonality and supplier behavior. Use measured minutes from your own queue.
Reviewers needed vs touchless rate
Sweeps Touchless rate from 40 to 98, holding your other inputs fixed.
Reduce reviewer hours
Optional: see which exceptions an on-prem agent could resolve automatically in your ERP.

How to use the calculator
Enter monthly document volume and your current or target touchless rate. Add the average review time for a standard exception and the share of hard exceptions that need research, such as missing PO or dispute. Set productive hours per FTE and utilisation to reflect breaks, meetings and training. The result is reviewer hours, FTE and monthly cost. Move the touchless slider to see the chart of staff needed at each rate.
The formula
Exceptions equal volume times one minus touchless rate. Hours equal standard exceptions times review minutes divided by sixty, plus hard exceptions times their minutes divided by sixty. FTE equals total hours divided by hours per FTE times utilisation. Cost equals hours times loaded hourly rate. The calculation is deliberately simple so you can check it against your own data.
Reading the chart
The curve is steep at low touchless rates and flattens as you improve. Going from 50 to 70 percent saves far more reviewer time than going from 90 to 95. That is why fixing the biggest root causes first pays back faster than chasing the last few percent. Compare the saving with the cost of the capture software before deciding on a target.
Common mistakes
Do not use the vendor's headline accuracy as a touchless rate, since they measure different things. Do not forget hard exceptions, which are few but use a large share of time. Include peak periods such as month end, when volume spikes and reviewers have less spare capacity.
Frequently Asked Questions
What is touchless rate?
It is the percent of documents that go from receipt to posting with no human intervention. It differs from field accuracy, because one wrong field is enough to make a document non-touchless.
What utilisation should I use?
Seventy to eighty percent is a common planning range for reviewers after breaks, meetings and context switching. Use your own time data if you have it, and lower the value for roles with many interruptions.
Does this include the software cost?
No. It covers human review labor only. Add license, hosting and support costs to compare total cost per document under different scenarios.
Why separate hard exceptions?
Hard exceptions, such as unmatched POs or price disputes, take several times longer than a simple correction. Averaging them hides where the time goes and makes staffing estimates too low.
Netray builds private agents that resolve common exceptions, like missing PO lookup, before a person sees them. We can size the effect for your volume.
