(33 ÷ 40) × 100 = 82.5%
Both conditions matter. An order that was on time but short, or complete but late, does not count in the OTIF numerator. Keep the definition of “on-time” consistent across the period you compare.
One strict numerator.Only orders that were both on-time and complete count as OTIF.
Your delivery rule.Use the same promised or required delivery-date definition across suppliers and periods.
Count first, interpret second.The calculator returns the percentage without inventing a universal supplier target.
What OTIF is actually measuring

OTIF combines two requirements into one supplier-performance measure: the order arrives on time, and the order arrives complete. Missing either condition means the order does not count as OTIF.

OTIF % = (orders both on-time and complete ÷ total orders) × 100

Keep the counting rule stable. If one month uses requested delivery date and another uses a supplier-confirmed date, the percentages are not directly comparable.

Worked supplier example

A supplier had 40 orders in the measurement period. Thirty-three arrived both on time and complete.

One percentage is useful. A history is better.

SupplyGrid keeps material orders, suppliers, expected dates and actual receipt history together so supplier OTIF can be tracked over time instead of counted manually once.

What should count as on-time and in-full
  • DATEChoose the delivery-date definition you actually manage against: required date, confirmed date or another agreed rule. Then keep it consistent.
  • FULLAn order is in-full only when the agreed quantity and required items are complete under your chosen counting policy.
  • BOTHOn-time but incomplete is not OTIF. Complete but late is not OTIF.
  • PERIODUse a meaningful measurement period. A percentage built from three orders behaves very differently from one built from forty.
  • TRENDA single result is a snapshot. Supplier performance is more useful when the same rule is tracked month after month.
Important: OTIF definitions vary between organizations. Decide what “on-time” and “complete” mean for your purchasing process before comparing suppliers or periods.
What this calculator does not tell you

OTIF is useful, but it is not a complete supplier scorecard. It does not capture price changes, defects, communication quality, lead-time variability, expedited freight, returns or how severe a late or incomplete order was.

Use it as one clean service measure, not as a substitute for the rest of supplier performance.

Method & sources

The percentage calculation is simple division. The external references below are included for the OTIF definition and supplier-performance context.

  1. ASCM — Distribution Channel Management metrics. Defines on-time in-full as the percentage of orders delivered on time and in full, and gives the same order-count formula used here.
  2. Oracle PeopleSoft — Supplier performance metrics. Documents supplier shipment measures for on-time performance, quantity performance and quality performance, reinforcing that OTIF is one part of broader supplier evaluation.

Common supplier OTIF questions

What does OTIF mean?

OTIF means on-time in-full. In this calculator, an order counts only when it satisfied both conditions.

Does an on-time but incomplete order count?

No. It fails the in-full condition, so it stays out of the OTIF numerator. The same is true for a complete order that arrived late.

Which delivery date should I use?

Use the date definition your purchasing process actually manages against, such as the required delivery date or an agreed confirmed date. The important part is consistency when comparing suppliers or periods.

Is there one universal good OTIF percentage?

No single target fits every supply chain, order type and service agreement. Use your own supplier expectations, customer requirements and historical performance rather than treating one generic threshold as universal.
