Review delivery performance for a week or month
A quick on-time rate can make it easier to compare service performance across time periods.
Work Tools
On-Time Delivery Rate Calculator
Estimate on-time delivery rate from total deliveries and the number completed on time.
Why this page exists
Delivery performance is easier to review when completed shipments turn into one on-time percentage instead of two separate counts in a report. This calculator helps visitors estimate on-time delivery rate, late-delivery count, and a simple service snapshot from the totals entered.

On-time delivery rate calculator
Estimate the percentage of deliveries completed on time from total deliveries and on-time deliveries.

92.98%
Estimated on-time delivery rate based on on-time deliveries divided by total deliveries.
On-time delivery rate92.98%
Late deliveries59
On-time deliveries781
Total deliveries840
- 781 on-time deliveries out of 840 total deliveries gives an on-time delivery rate near 92.98%.
- 59 deliveries fall outside the on-time count in this simple estimate.
- Use this as a straightforward service metric only, because different teams can define on-time performance differently.
This is a basic operations metric. The result depends on how on-time performance is defined and whether early deliveries, partial shipments, or reattempts are counted.

FAQ
Common questions
How is on-time delivery rate calculated?
The calculator divides on-time deliveries by total deliveries to estimate the percentage completed on time.
Why show late deliveries too?
The late-delivery count can make the percentage easier to understand in practical operational terms.
Can delivery teams define on-time differently?
Yes. Some teams count early deliveries, split shipments, or special exceptions differently, so the result should be treated as a basic planning metric.
