Formula Used
Total Turnaround = Completion Time − Order Received Time
Net Turnaround = Total Turnaround − Downtime Hours
Active Handling = Picking Time + Packing Time
Average Stage = Sum of Stage Durations ÷ Number of Measured Stages
Throughput Per Day = Batch Size ÷ (Total Turnaround ÷ 24)
Efficiency Ratio = Active Handling ÷ Net Turnaround × 100
Delay Cost = max(Total Turnaround − Promised Hours, 0) × Delay Cost Rate

FAQs
1. What is order turnaround time?
Order turnaround time is the elapsed time between order receipt and the selected completion point, usually shipment or delivery. It helps teams measure speed, identify bottlenecks, and improve service reliability.
2. Should I choose shipped or delivered?
Choose shipped when your workflow ends once the parcel leaves the facility. Choose delivered when you want the full customer-facing cycle, including transit time, in the turnaround result.
3. Why include downtime hours?
Downtime hours help remove known pauses, such as system outages, warehouse holds, or scheduled stops. This gives a cleaner net turnaround figure for operational review.
4. What does efficiency ratio mean here?
The efficiency ratio compares active handling time against net turnaround time. A higher percentage means more time was spent doing productive fulfillment work instead of waiting.
5. How is SLA status decided?
The calculator compares total turnaround hours with promised hours. It marks the order as on time, slightly late, or critically delayed based on the size of the overrun.
6. What is throughput per day?
Throughput per day estimates how many orders can move through the same cycle in twenty-four hours, based on batch size and total turnaround time.
7. Can I use this for warehouse teams?
Yes. The stage structure fits warehouse, fulfillment, courier, and logistics operations. You can adapt the timestamps to match your internal workflow checkpoints.
8. Why is my delivered field sometimes dimmed?
When the completion point is set to shipped, delivery is not required for calculation. The field stays available, but it becomes visually muted because it is optional.
