Understanding On-Time Delivery Rate
How we calculate. OTD % = on-time deliveries ÷ total deliveries × 100. The form uses the same arithmetic as the worked examples on this page. See our methodology and accuracy policy.
Real-world scenario: A typical On-Time Delivery Rate case uses on-time shipments 920 and total shipments 1000. Enter the same figures below to reproduce the worked path.
What is On-Time Delivery Rate?
A core customer-service logistics KPI. Define “on time” as arrival by appointment, by requested date, or by carrier SLA—and keep that rule stable.
- Same shipment set in numerator and denominator
- Define the delivery window clearly
- Segment by lane or mode for diagnosis
The Formula
Worked Example
Common Use Cases
- Carrier scorecards: OTD by partner
- Customer SLAs: promised vs actual
- Network reviews: lane reliability
Pro Tips
- Exclude cancelled orders if policy says so
- Separate early vs late when analyzing root cause
- Pair with OTIF for completeness
Limitations: On-Time Delivery Rate results are educational logistics and supply-chain planning aids—not SLAs, carrier contracts, or inventory valuation advice. Confirm definitions with your WMS/TMS and finance policies.
FAQ
Is early delivery counted as on time?
Only if your policy says so. Some customers treat early arrivals as failures—document the rule.
What if total shipments is 0?
OTD is undefined—enter a positive shipment count.
