How do you calculate on-time delivery rate?

Divide on-time deliveries by total delivered shipments, then multiply by 100. With 940 on-time out of 1,000 delivered, the OTD rate is 94%.

What is a good on-time delivery rate?

Most shippers target 95-98%, and major retail scorecards often demand 97% or higher. The worked example's 94% sits 3 points below a 97% target, which on a retail scorecard could trigger chargebacks.

What counts as an on-time delivery?

A shipment that arrives within the agreed window — whether that's the requested delivery date, the appointment time, or a must-arrive-by date. The exact rule must be defined up front, because it drives whether borderline loads count as hits or misses.

On-time delivery vs on-time shipment — what's the difference?

On-time shipment measures whether freight left your dock on schedule; on-time delivery measures whether it arrived on schedule. OTD includes transit and carrier performance, so it can be lower than your ship-on-time rate.

Why is my OTD rate below target?

Common causes are unreliable lanes or carriers, tight transit times with no buffer, dock scheduling conflicts, and appointment misses. A 3-point gap like the example usually traces to one or two problem lanes rather than a system-wide issue.

How can I improve on-time delivery rate?

Identify the lanes and carriers driving late deliveries, add realistic transit buffers, tighten appointment scheduling, and hold underperforming carriers to scorecards. Recovering the 3-point gap is usually about fixing the worst-performing lanes first.

Transportation, Freight & Distribution calculator

On-Time Delivery Rate Calculator

On-time delivery rate (OTD) is the percentage of shipments that arrive within the committed delivery window, out of all shipments delivered in a period. It is the headline reliability metric in transportation, freight, and distribution because it directly shapes customer trust, chargebacks, and whether you keep preferred-carrier or vendor status with major retailers. Logistics managers, carrier-performance analysts, and distribution leads track OTD to flag lane problems, carrier underperformance, and dock or routing bottlenecks before they trigger penalties or lost accounts. Many large customers enforce OTD scorecards with financial consequences, so even a few points below target can mean real money and relationship risk.

What this calculator does

Calculate on-time delivery performance from on-time shipments, total delivered shipments, and the customer or internal OTD target.
Use it for carrier scorecards, customer service reviews, distribution KPI boards, and late-shipment root cause work.
It computes the percentage of delivered shipments that arrived on time and the gap between that rate and your OTD target.

Formula used

On-Time Delivery Rate rate = on-time deliveries ÷ total delivered shipments × 100
Gap to target = target otd rate - on-time delivery rate rate

Inputs explained

On-time deliveries: Shipments delivered within the agreed appointment, promised date, or SLA window.
Total delivered shipments: All delivered shipments in the same carrier, lane, customer, or reporting period.
Target OTD rate: Customer requirement or internal target for on-time delivery.

How to use the result

Use it weekly or per shipping cycle to monitor carrier and lane reliability and to back up conversations with carriers or customers about delivery performance.
The result depends entirely on how you define 'on time' (delivery date, appointment window, must-arrive-by date); inconsistent definitions across carriers or customers make the number hard to compare.

Current U.S. benchmarks

On-highway diesel averages $4.58 per gallon this week (EIA), trending down over recent periods. Truck tonnage is up 3.4% year over year (ATA via FRED).
