Quick Summary
- Measuring delivery performance with nine clear KPIs (including on‑time delivery, order accuracy, first attempt delivery rate, average time and cost per delivery, out‑of‑route miles, capacity use, and NPS) lets you see exactly where time, money, and customer satisfaction are won or lost.
- Tracking on‑time delivery and first attempt delivery rate together helps you reduce repeat visits by tightening time windows, improving routing, and fixing address issues on the worst‑performing routes first.
- Improving order accuracy by standardizing picking, packing, and data entry (for example, using barcodes and simple checks) cuts returns, re‑deliveries, and support contacts, while lifting customer satisfaction scores.
- Watching average cost per delivery alongside out‑of‑route miles and vehicle capacity use shows where you can shorten routes, fill vehicles better, or adjust service areas to keep cost per drop within a sustainable range.
- Reviewing these KPIs regularly, comparing them to realistic benchmarks (such as ~95% on‑time delivery and ~98% order accuracy), and making small, targeted changes creates a feedback loop that steadily lifts overall delivery performance.
In delivery operations, delivery performance is the link between your business and your customers, showing how reliably you move orders from A to B. To measure delivery performance properly, you need clear KPIs that tell you where time, cost, and accuracy are slipping and where you are doing well.
By tracking these delivery performance metrics over time, you can spot bottlenecks early, decide where to invest, and prove to the rest of the business that your delivery operation is improving.
In this guide, we break down 9 delivery performance KPIs you can measure today, from on‑time delivery to cost per drop and NPS.
What is Delivery Performance?
Delivery performance refers to how well a business handles its delivery operations. It is a measure of how often you meet customer expectations and complete deliveries on time and without errors.
For businesses that handle goods, be it as their primary focus or as part of their operations, delivery performance plays a critical role in customer satisfaction and overall results. By monitoring and analyzing delivery performance, businesses can identify areas for improvement and implement strategies to improve their delivery management.
Strong delivery performance helps keep resources focused on the right work, reduces unnecessary costs, and leaves customers happy with the speed and reliability of your service.
Monitoring and analyzing delivery performance through specific KPIs and delivery metrics helps businesses clearly see strengths, weaknesses, and where they need to improve.
What Can Affect Your Delivery Performance?
Route Optimization: Inefficient route planning can lead to longer delivery times, increased fuel costs and reduced overall productivity. Delivery vehicles may end up taking suboptimal paths, leading to unnecessary delays and higher operational expenses. If you are still planning routes by hand or in spreadsheets, this is a strong sign that it’s time to look at dedicated route scheduling software that can do the heavy lifting for you.
Vehicle Maintenance: The reliability of delivery vehicles plays a big part in on-time deliveries. Properly maintained vehicles are essential for ensuring that goods reach their destinations as scheduled and for preventing unexpected breakdowns that can disrupt the delivery schedule.
Inventory Management: Accurate inventory data is central to reliable deliveries. Without precise information on available stock, businesses risk encountering delays due to stockouts or errors in fulfillment.
External Factors: The changing nature of the external environment can pose challenges to delivery performance. Weather conditions, road closures, traffic congestion, or unforeseen events can disrupt delivery schedules and impact delivery performance. While these external factors may be beyond a business's control, having contingency plans and real‑time data can help businesses adapt quickly and limit the impact on delivery operations. If you rely on outsourced delivery or 3PL partners, shared performance dashboards and clear SLAs are essential to keep delivery performance on track.
Communication and Coordination: Effective communication and coordination are vital for smooth, reliable deliveries. Drivers, dispatchers, and customers must be in sync throughout the delivery process to ensure that goods are delivered accurately and on time. Ineffective communication can lead to confusion, missed deliveries, and dissatisfied customers.

Why It’s Important to Measure Delivery Performance
Here are some of the main reasons why measuring delivery performance matters for businesses:
Customer Satisfaction
A reliable customer base is what keeps any business going. Delivery performance has a direct impact on customer satisfaction.
When customers receive their orders on time and with accuracy, it creates a positive experience that builds trust and loyalty.
Satisfied customers are more likely to become repeat buyers and recommend your services to others, which helps you grow through word of mouth.
Operational Efficiency
Measuring key performance indicators (KPIs) and metrics related to delivery performance gives businesses clear visibility into how their operation is running.
When a delivery performance report highlights bottlenecks, inefficiencies, and areas for improvement, teams can adjust their processes to remove friction.
Strong day‑to‑day operations lead to shorter delivery times, higher productivity, and lower operational costs. With this information, businesses can direct resources where they have the most impact and use time and budget more carefully.
Cost Optimization
Understanding delivery costs is key to using resources well and improving profitability.
Measuring delivery performance metrics such as average cost per delivery allows businesses to pinpoint where spending is higher than it needs to be.
From fuel costs and vehicle maintenance to labor and routing issues, finding cost‑saving opportunities helps businesses stay financially sustainable and protect their margins.
Competitive Advantage
Consistently delivering on what you promise and meeting customer expectations sets your business apart from others.
A strong reputation for reliable delivery makes it easier to win new customers and keep existing ones.
Continuous Improvement
Regularly measuring delivery performance helps businesses respond to changing market demands.
By spotting issues early, teams can make changes to their services and keep delivery performance closely aligned with what customers expect.
9 KPIs for Measuring Delivery Performance
Understanding how to measure delivery performance is key to improving efficiency and keeping customers happy. The right KPIs and metrics help track everything from on-time rates to customer satisfaction, giving you the insights needed to refine your delivery process. Here are the top ones to focus on:
1. Number of Completed Deliveries
No. of Completed Deliveries = Total Deliveries Dispatched - Failed or Returned Deliveries
Industry benchmark: Instead of a fixed target, many teams monitor completed deliveries per route or per driver over time and aim for a steady upward trend while keeping failed delivery rates under 5%.
The number of completed deliveries is a useful measure of how well a business’s delivery operation is working. This metric gives a clear view of how many deliveries are finished within a specific time frame.
It does more than just count drops; it reflects planning quality, day‑to‑day execution, and how reliably you deliver on promises made to customers. As this number grows, it signals stronger reliability and better support for customer satisfaction.
While a high number of completed deliveries looks positive, it can also highlight potential challenges. A sudden surge in deliveries that stretches capacity may lead to delays or errors. By watching this metric closely, businesses can spot capacity constraints and direct resources where they are needed to keep service levels steady.
2. Order Accuracy
Order Accuracy (%) = (Accurate Orders ÷ Total Orders) x 100
Industry benchmark: Order accuracy targets of around 98% or higher are a realistic goal for well‑run operations.
This metric measures the percentage of deliveries completed without errors, making sure the right items, in the correct quantities, reach customers as intended. When you focus on order accuracy, it becomes a key point in the delivery journey that can strengthen your reputation or, if ignored, lead to customer complaints.
Order accuracy has a direct impact on customer satisfaction. When customers receive exactly what they ordered, it creates a straightforward, positive experience. In contrast, problems such as wrong items or quantities lead to frustration, extra work for your team, and a loss of trust in your delivery promises. Keeping delivery accuracy high is important for building loyal, repeat customers over time.
Order accuracy does not come down to luck; it relies on clear systems and consistent processes. Using reliable inventory management, barcode or scanning tools, and simple but firm quality checks all help keep orders accurate.
3. First Attempt Delivery Rate
First Attempt Delivery Rate (%) = (Successful First‑Attempt Deliveries ÷ Total Deliveries) × 100
Industry benchmark: Many parcel networks aim for a first attempt delivery rate above 90%, while best‑in‑class eCommerce fleets push towards 95%+ in dense urban areas.
This KPI measures the percentage of deliveries successfully completed on the first attempt, without the need for re‑deliveries or extra trips. A high first attempt delivery rate usually points to a delivery process that saves time, reduces wasted effort, and supports better customer satisfaction.
Every successful delivery on the first try cuts operational costs and gives the customer a straightforward, positive experience. Strong performance here depends on solid routing, realistic scheduling, and clear planning.
Reaching a high first attempt delivery rate depends on good routing and scheduling. Well‑planned routes and practical schedules help drivers reach their stops with fewer delays. By planning routes carefully and using real‑time traffic data, businesses can increase the share of deliveries completed on the first attempt, saving time and limiting fuel use.
4. On Time Delivery
On Time Delivery Rate (%) = (On‑Time Deliveries ÷ Total Deliveries) × 100
Industry benchmark: In eCommerce, on‑time delivery rates of around 95% are widely treated as a solid standard, with market leaders pushing closer to 98%+.
The on time delivery rate measures the percentage of deliveries completed within the promised timeframe, reflecting a business's ability to meet customer expectations and stick to agreed delivery schedules. When customers receive their orders on time, they are more likely to feel valued, leave positive reviews, order again, and recommend your service to others.
On‑time delivery metrics show whether the business has a well‑organized delivery process, sensible routes, and realistic schedules. By aiming for high on‑time delivery rates, businesses can improve how their operation runs and give customers a more predictable delivery experience.
Achieving on‑time delivery is not without its challenges; factors such as weather conditions, traffic congestion, or unforeseen events can disrupt delivery schedules. Businesses that address these challenges early and have contingency plans in place show they are serious about delivering on time, even when conditions are difficult.
To go a step further than basic on‑time delivery, many teams also track OTIF (On‑Time In‑Full), which measures whether orders arrive both on time and with every item included.
5. Average Time Per Delivery
Average Time per Delivery = Total Delivery Time ÷ Total Deliveries
Industry benchmark: Many last‑mile teams track average delivery time by zone and product type, aiming to keep typical eCommerce orders within a 2-4 day delivery window from order to doorstep.
Average time per delivery is a useful metric that shows how long it typically takes to complete a delivery from the moment goods leave the fulfillment center to their arrival at the customer's doorstep.
Businesses can use this number to set benchmarks, track progress, and compare performance across different periods.Looking at the average time per delivery helps businesses spot slow points in the process. Long delivery times may signal issues such as poor routing, low vehicle fill‑rates, or delays in order processing. By finding these problem areas, businesses can take focused steps to fix them and shorten delivery times.
Route planning and scheduling play a big part in keeping the average time per delivery under control. Businesses can use routing software and real‑time traffic data to plan delivery routes, cut unnecessary travel time, and lower the chance of delays.
6. Average Cost Per Delivery
Average Cost per Delivery = Total Delivery Cost ÷ Total Deliveries
Industry benchmark: Average shipping costs typically account for around 10-15% of order value across many categories, with heavier or bulkier products pushing that percentage higher.
The average cost per delivery measures the typical expense involved in completing each delivery, including fuel, labor, maintenance, and vehicle depreciation.
By breaking down these cost components, businesses get a clearer view of how delivery work affects their finances. This information helps teams make better decisions about where to spend and where to save. For example, if fuel costs are high, they can look at more fuel‑efficient vehicles, adjust delivery routes to cut distance, or test alternative delivery methods to lower fuel use. Understanding these cost drivers makes it easier to put focused cost‑saving measures in place.
7. Out-Of-Route Miles
Out‑of‑Route Miles = Actual Miles Driven − Planned Route Miles
Industry benchmark: “empty mileage” and cost per mile are critical efficiency KPIs, so any sustained increase in out‑of‑route miles is a red flag for rising last‑mile costs.
These extra miles add unnecessary fuel costs, increase delivery times, and make the operation harder to run well.
Cutting out-of-route miles has a direct impact on fuel use, which helps both with cost control and environmental goals. By planning routes carefully and reducing unnecessary travel, businesses can lower fuel consumption, reduce greenhouse gas emissions, and support more responsible delivery practices.
Out-of-route miles can lead to longer delivery times, which hurts the customer experience. By tightening up routes, businesses can improve delivery times, improve customer satisfaction, and build stronger long‑term customer relationships.
8. Vehicle Capacity Utilization
Vehicle Capacity Utilization (%) = (Used Capacity ÷ Total Available Capacity) × 100
Industry benchmark: Best‑in‑class last‑mile operations often maintain vehicle capacity utilization above 80%, especially on dense urban routes.
For businesses that handle deliveries in varying quantities, using vehicle capacity well is key to keeping operations under control, reducing the number of trips, and lowering delivery costs.
By knowing how much of a vehicle's capacity is used on each run, businesses can plan delivery routes so each trip carries a sensible load. This kind of planning reduces fuel consumption, lowers vehicle wear and maintenance costs, and supports a more efficient day‑to‑day operation. When capacity use is high, you usually need fewer trips to move the same volume. With fewer trips, businesses can cut costs and reduce the environmental impact of their delivery work.
9. Net Promoter Score (NPS)
NPS = % Promoters (9–10) − % Detractors (0–6)
Industry benchmark: Broad NPS research suggests that many brands sit somewhere between 0 and 30, while scores in the 30-50 range are often seen as strong and anything above 50 as excellent
The Net Promoter Score (NPS) is a metric focused on customer satisfaction and loyalty. While it is not tied to any single delivery step, NPS shows how customers feel about their overall delivery experience and how likely they are to recommend your service to others. A strong NPS usually goes hand in hand with higher loyalty, more repeat orders, and more word‑of‑mouth referrals.
A high NPS is useful, but the written feedback from Promoters, Passives, and Detractors often matters just as much. By asking for feedback regularly and listening to what customers say, businesses can spot issues, fix pain points, and steadily improve the delivery experience.

FAQ
1. What are Key Performance Indicators (KPIs) for measuring delivery performance?
Key Performance Indicators (KPIs) are delivery metrics that show how well your operation is running. For delivery performance, useful KPIs include On‑Time Delivery (OTD), First Attempt Delivery Rate, Order Accuracy, Average Cost per Delivery, Out‑of‑Route Miles, Vehicle Capacity Utilization, and customer‑facing scores such as Net Promoter Score (NPS). Together, these metrics give you a clear view of speed, reliability, and cost in your delivery work.
2. How do I calculate on-time delivery performance?
To calculate on‑time delivery performance, use this formula:
On‑Time Delivery Rate (%) = (On‑Time Deliveries ÷ Total Deliveries) × 100
For example, if you complete 950 deliveries on time out of 1,000 in a given period, your on‑time delivery rate is 95%.
3. What is a good on-time delivery rate and order accuracy?
A useful target for many delivery teams is an on‑time delivery rate of at least 95%, with anything above that putting you closer to top performers in eCommerce and retail. For order accuracy, benchmarks around 98% or higher are often used as a practical goal, because even small errors create returns, extra support work, and frustrated customers. The right target for your business will depend on your products and service promise, but if you are well below these ranges, it is a clear sign to review routes, processes, and data quality.
4. Which delivery performance metrics should I track first?
If you are just getting started, focus on a small set of delivery performance metrics that give you a balanced view of speed, reliability, and cost. A simple starting point is to track on‑time delivery rate, first attempt delivery rate, order accuracy, and average cost per delivery. These four metrics quickly show whether customers are getting orders when promised, whether drivers are making too many repeat visits, how often orders are wrong, and how much each drop costs you. Once these are in place, you can add more detail with out‑of‑route miles, vehicle capacity use, or NPS where needed.
5. How can I use these shipping metrics to improve my delivery operations?
You can use these metrics to improve your delivery operations by turning them into a simple feedback loop:
- Pick a small set of core KPIs to watch (for example on‑time delivery, first attempt delivery rate, and average cost per delivery).
- Set clear targets for each metric and share them with your team.
- Review the numbers regularly to spot routes, vehicles, or time windows that fall behind.
- Test focused changes, such as adjusting time windows, tightening routing rules, or updating driver instructions.
- Check the same KPIs again to see whether the changes moved the numbers in the right direction.
Repeating this process over time helps you cut waste, reduce delays, and make the delivery experience more reliable for customers.
