On-Time Delivery Rate
The percentage of deliveries completed by the promised or agreed delivery time.
Business question
What share of deliveries reached completion by the promised time?
Formula
On-time delivery rate = (deliveries completed by the promised time ÷ deliveries due in the reporting period) × 100.
Calculation notes
Define the promised or agreed delivery timestamp, grace period if any, and which deliveries are due in the period.
Edge-case guidance
If no deliveries are due, report the measure as not available. Keep customer-requested changes and business-caused delays distinguishable.

Interpretation
Use the measure to monitor delivery reliability and investigate demand, capacity, scheduling, supplier, and handoff constraints.
Caution
An on-time result can look strong if promised dates are extended or if completed deliveries are counted without the full due population.
Implementation recommendation
Capture the promised timestamp at commitment and record delay reasons so improvement work addresses the actual constraint.
Target guidance
Set the first target from a comparable historical baseline for on-time delivery rate, then adjust it for strategy, capacity, seasonality, data quality, and relevant market or regulatory context. Review the direction with the accountable business owner rather than treating any external benchmark as universal.
