11 KPIs to Measure Your Carrier Performance
Choosing a freight carrier is only the beginning. Shippers also need to know whether their carriers are meeting expectations after the freight starts moving.
Carrier performance KPIs give you a clear way to measure service, cost, reliability, and communication.
Instead of relying on individual shipment experiences, you can use real data to compare carriers and spot problems before they become bigger issues.
The right metrics can help you answer questions such as:
- Are shipments being picked up and delivered on time?
- Is the carrier accepting the freight you tender?
- Are damage claims increasing?
- Are invoices accurate?
- Are accessorial charges becoming more common?
- Is available trailer space being used efficiently?
Here are 11 carrier performance KPIs worth tracking.
1) On-Time Payment
Carrier relationships work both ways. While most carrier KPIs measure the transportation provider, shippers should also track whether they are meeting their own payment obligations.
Late payments can create friction with carriers and make it harder to maintain strong transportation partnerships.
How to measure it:
On-Time Payment Rate = On-Time Payments ÷ Total Payments × 100
Review late payments regularly and determine whether delays are caused by invoice disputes, internal approvals, missing documents, or other issues.
A reliable payment process helps create a healthier long-term relationship between the shipper and carrier.
2) Electronic Invoice Adoption
- The percentage of invoices received electronically
- How often electronic invoices contain errors
- How long invoices take to process
- How often employees must manually correct billing information
Greater automation can make freight auditing and payment more efficient.
3) Capacity Reliability
A low rate means little if the carrier cannot provide a truck when you need one.
Capacity reliability measures how consistently a carrier can handle the freight you expect to tender.
Frequent capacity problems may lead to missed pickups, higher spot-market costs, or last-minute carrier changes.
Consider tracking:
- Loads accepted
- Loads rejected because of capacity
- Missed pickups
- Last-minute cancellations
- Backup carriers required
Review these numbers by carrier, lane, season, and freight type. A carrier may perform well overall but struggle with certain lanes or during peak shipping periods.
4) Routing Guide Compliance
A routing guide tells employees, vendors, and shipping locations which carriers and transportation methods should be used.
When the guide is not followed, transportation costs can rise quickly.
Measure how often shipments follow the approved routing process and investigate exceptions.
Common issues may include:
- Using an unapproved carrier
- Selecting the wrong freight service
- Booking outside negotiated agreements
- Failing to follow required shipping instructions
You can also compare expected transportation costs with actual spending to see whether your routing strategy is working as planned.
5) Tender Acceptance Rate
Tender Acceptance Rate = Accepted Loads ÷ Total Tendered Loads × 100
A carrier that frequently rejects freight may force you to use more expensive backup options.
When acceptance rates fall, look deeper before assuming the carrier is the problem. Capacity constraints, difficult appointment times, poor-performing lanes, short lead times, or changes in shipping volume may also contribute.
Tracking the reason behind rejected tenders gives you much more useful information than tracking the rejection alone.

6) Driver Performance and Safety
Drivers are one of the most visible parts of the freight transportation process.
Their performance can affect pickup times, delivery times, freight condition, facility operations, and customer experience.
Carrier evaluations can consider whether drivers:
- Arrive within scheduled appointment windows
- Follow facility procedures
- Handle freight properly
- Communicate delays
- Complete required documentation
- Follow applicable transportation safety requirements
For motor carriers, shippers can also review information and safety resources provided by the Federal Motor Carrier Safety Administration (FMCSA).
Driver performance should not be judged from one isolated shipment. Look for patterns across multiple loads.
7) Transportation Utilization
Transportation utilization looks at how efficiently you are using the space and capacity you purchase.
For example, several large LTL freight shipments moving along similar routes may eventually make a full truckload or partial truckload option worth considering.
Look at:
- Trailer space used
- Weight and cube utilization
- Number of shipments consolidated
- Cost per shipment
- Cost per pound
- Cost per pallet
- Transportation mode used
The goal is not simply to fill every trailer. It is to choose the transportation option that makes the most sense for the freight, timeline, and budget.
8) Accessorials as a Percent of Freight Spend
Accessorial charges cover services outside the basic transportation rate.
Examples may include:
- Liftgate service
- Residential delivery
- Inside delivery
- Detention
- Redelivery
- Limited-access pickup or delivery
Track how much you spend on these charges compared with your total freight spending.
How to measure it:
Accessorial Cost Percentage = Accessorial Charges ÷ Total Freight Spend × 100
A rising percentage does not automatically mean a carrier is performing poorly. However, it can reveal recurring shipping problems.
For example, frequent detention charges may point to slow loading or unloading. Repeated address corrections could indicate problems in your order-entry process.
Breaking accessorials down by type, carrier, facility, and lane can help uncover the root cause.

9) Invoice Accuracy
Freight invoices should match the rates and services you agreed to.
Billing errors create extra administrative work and can make transportation costs harder to predict.
Track:
- Total invoices received
- Invoices with errors
- Type of billing error
- Amount disputed
- Time required to resolve disputes
- Errors by carrier
How to measure it:
Invoice Accuracy = Accurate Invoices ÷ Total Invoices × 100
You can also group errors by category. For example, determine whether disputes involve freight classification, weight, accessorial charges, fuel surcharges, or contracted rates.
This makes it easier to see whether an issue is isolated or part of a larger pattern.
10) Damage Claim Rate
A shipment that arrives on time but damaged is not a successful shipment.
Damage claims can help show how well freight is being handled throughout transportation.
Track:
- Number of claims
- Claims by carrier
- Claims by lane
- Claims by commodity
- Claim value
- Claims as a percentage of shipments
- Average time required to resolve a claim
One useful calculation is:
Damage Claim Rate = Shipments With Damage Claims ÷ Total Shipments × 100
When claims increase, investigate the cause.
The carrier may not always be responsible. Packaging, pallet construction, loading practices, or commodity characteristics can also contribute to freight damage.
Looking at the underlying cause helps determine whether you need to address carrier performance, packaging, or another part of the shipping process.
11) On-Time Pickup and Delivery
On-time performance is one of the most important carrier KPIs.
Track pickup and delivery separately so you can see where delays occur.
On-Time Pickup
On-Time Pickup Rate = On-Time Pickups ÷ Total Pickups × 100
On-Time Delivery
On-Time Delivery Rate = On-Time Deliveries ÷ Total Deliveries × 100
You may also want to track on-time departures when freight moves through your own facilities.
Before comparing carriers, clearly define what your business considers “on time.”
For one operation, arriving 30 minutes after an appointment may count as late. Another business may use a larger delivery window.
Whatever standard you choose, apply it consistently.
Then review performance by:
- Carrier
- Lane
- Facility
- Freight service
- Customer
- Month or quarter
If one carrier regularly struggles on a particular lane, the problem may be much easier to identify when the data is separated instead of included in one companywide average.
