Work out supplier on time delivery rate instantly with clear inputs, formula shown and shareable results.
On time in full is the strictest delivery measure: a delivery counts only if it arrives within the agreed window and complete. Multiplying late deliveries by the expediting cost turns a percentage into the currency figure that supports a supplier improvement conversation.
OTIF rate
OTIF % = Deliveries on time and in full / Total deliveries x 100
Expediting cost
Cost = Late deliveries x Expediting cost per late delivery
Not usually. Early delivery creates unplanned storage and cash flow effects, so most OTIF definitions require arrival within a window.
95%+ for stable, high-volume supply; 85-90% for engineered or long lead-time items where forecast accuracy is inherently poorer.
