How do you calculate carrier on-time performance workload hours?

Divide the shipment records to review by your audit rate to get base hours, then multiply by one plus the investigation allowance. With 320 records at 42 records per hour and a 25% allowance, base hours are 7.62 and total workload is 9.52 hours.

What is a good audit rate for OTP reviews?

Clean electronic records with EDI 214 status milestones can move at 40 to 60 records per hour; manual PDF proof-of-delivery reviews often drop to 15 to 25. The 42 records per hour default sits in the automated-data range.

Why add an investigation allowance?

Late shipments require pulling tracking events, detention logs, and carrier notes to assign fault. The allowance (25% here) reserves time for that research so your estimate is not just the happy-path audit speed.

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

On-time performance (OTP) usually measures against the carrier's committed transit or appointment window, while on-time delivery (OTD) measures against the customer's requested date. This calculator sizes the labor to audit either metric.

How many records should I review?

For a defensible carrier scorecard, audit a statistically valid sample or the full late-shipment population plus a control sample of on-time loads. The 320-record default reflects a mid-size lane review.

How do I reduce the audit workload?

Automate status ingestion via EDI 214 or API tracking so records self-populate, and reserve manual investigation for exceptions only. That both raises the audit rate and shrinks the investigation allowance.

Carrier On-Time Performance Workload Calculator

Carrier on-time performance workload is the labor time a logistics or transportation team needs to audit shipment delivery records against promised delivery windows. Freight analysts, carrier managers, and distribution supervisors use it to staff quarterly business reviews and OTP scorecards. Auditing every record takes time, and delayed shipments demand extra digging into tracking events, appointment logs, and detention records. Estimating the hours up front keeps carrier reviews on schedule instead of bleeding into the next reporting cycle.

What this calculator does

Estimate review workload for carrier on-time performance from shipment records, records reviewed per hour, and investigation allowance.
Use it to plan carrier scorecard reviews, late-shipment investigations, and exception management labor.
It converts a stack of shipment records and an audit rate into total review hours, then adds an investigation allowance for chasing down late deliveries.

Formula used

Base hours = shipment records to review ÷ review rate
Total hours = base hours × (1 + investigation allowance)

Inputs explained

Shipment records to review:
Records audited per hour:
Investigation allowance:

How to use the result

Use it before a carrier scorecard cycle, a quarterly business review, or a claims-heavy period when you need to defend headcount for the OTP audit.
It assumes a steady audit rate; records with disputed appointment times or missing tracking events can take far longer than the average, so a high late-delivery mix may blow past the flat allowance.

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).
