Estimate how many completed survey records a team can validate or process in a workday. The calculation combines handling speed, staff count, productive hours, utilization, and the share of submitted records that remain usable. It reports usable daily output, gross records processed, time per record, and a 20-workday projection for practical staffing and backlog planning.
Gross daily records = rate × staff × hours × utilization. Usable daily records = gross daily records × usable rate.
The primary result is conditional on the values and statistical assumptions entered. Read the secondary results to understand uncertainty, workload, or design sensitivity before making a decision.
This planning estimate is not a substitute for a study protocol, domain review, or a method chosen for the final data distribution.
At 35 records per hour, six staff, 7.5 hours, 80% utilization, and a 92% usable rate, gross capacity is 1,260 records and usable capacity is 1,159.2 records per day.
The calculator uses a standard statistical approximation. Small samples, highly skewed outcomes, or model misspecification can make the estimate less accurate.
Yes. A 90% setting gives a narrower interval or lower sample requirement, while a 95% setting provides more conservative coverage.
Use zero only where the input allows it. A rate calculation still needs a positive total or a defined prior so that division by zero is avoided.
No. It summarizes uncertainty or planning assumptions; study design, randomization, measurement quality, and confounding still matter.
Keep rates and intervals at the shown precision, but round required counts upward because a fraction of a sample or processing unit is not usable.
| Item | How it is used |
|---|---|
| Observed or planned sample | Sets the available evidence or workload. |
| Uncertainty setting | Controls interval width or rejection threshold. |
| Variability or rate | Translates the sample into uncertainty, power, or capacity. |
