What Are Last-Mile Delivery Metrics and KPIs?

Last-mile delivery metrics are quantifiable indicators that measure the performance, cost, and quality of the final leg of your delivery process, from the distribution hub to the customer's doorstep.

They give logistics teams a data-driven view of how efficiently orders are being fulfilled, where bottlenecks exist, and how the delivery experience impacts customer satisfaction. These KPIs cover everything from delivery speed and accuracy to fuel consumption and route efficiency.

Tracking them consistently allows businesses to benchmark performance, set improvement targets, and make informed operational decisions rather than relying on guesswork.

10 Last-Mile Delivery KPIs to Measure and Improve Last-Mile Logistics Performance

Before you improve anything, you need to measure it. That is particularly true for the last mile, which is the most complex, expensive, and customer-facing leg of your supply chain. Measuring last-mile delivery metrics offers real-time visibility into operational performance and exposes areas for optimization.

Be it customer feedback, route optimization, or overall delivery efficiency, these KPIs offer a competitive advantage. They are direct indicators of delivery speed, accuracy, customer satisfaction, and cost control. Let's break down the 10 most critical last-mile KPIs every logistics team must track and improve.

1. On-Time Delivery Rate (OTD): How to Measure and Improve It

The on-time delivery rate tracks the percentage of deliveries that arrive at the customer's doorstep within the promised delivery window. The on-time delivery success rate measures order accuracy, i.e., how accurately your delivery operations align with scheduled delivery times.

A high OTD improves service quality, optimizes average service time, and builds customer loyalty, while consistent delays negatively impact customer satisfaction. Monitoring this KPI helps businesses improve delivery schedules, enhance route planning, and refine logistics workflows.

An optimized OTD also contributes to lower customer churn and boosts your brand's reliability. Persistent shipping delays are one of the most common drivers of a poor OTD score and should be investigated at the route and carrier level.

Formula: OTD Rate = (Deliveries completed within promised window / Total deliveries) x 100

Benchmark: Industry leaders target 95% or higher.

2. Delivery Cost Per Package: How to Calculate and Reduce Last-Mile Costs

This metric measures the last-mile delivery costs. It is the total cost incurred to deliver a single package, including fuel costs, labor, vehicle maintenance, and software expenses. It serves as a comprehensive snapshot of the financial health of your last-mile delivery solution.

By analyzing this KPI, businesses can identify cost drivers such as inefficient routes, long idle times, or high fuel consumption. Reducing the delivery cost per package improves profitability, enables competitive pricing, and helps companies scale delivery operations without increasing logistics costs disproportionately.

Formula: Cost Per Package = Total last-mile delivery costs / Total packages delivered

Benchmark: Varies by market, but keeping this below $10 per package is a common target for e-commerce.

3. First Attempt Delivery Success Rate: What It Is and How to Improve It

This KPI tracks the percentage of packages successfully delivered on the first attempt, without needing a re-delivery. It is a crucial measure of delivery efficiency and customer service quality.

Failed delivery attempts increase delivery cost, burden the logistics team, and frustrate customers. Improving this metric often requires better route optimization, real-time communication with recipients, and accurate address validation.

A high success rate reduces operational costs and enhances customer satisfaction. Teams focused on reducing delivery failures and RTOs will find first attempt success rate to be one of the most actionable metrics to target.

Formula: First Attempt Success Rate = (First attempt deliveries / Total delivery attempts) x 100

Benchmark: Top-performing logistics teams aim for 90% or above.

4. Average Delivery Time: Benchmarks and How to Reduce It

Delivery time measures how long it takes from dispatch to delivery at the customer's address. It plays a vital role in creating an efficient delivery process, meeting customer expectations, and improving overall delivery performance.

Delays in delivery time can result from poor route planning, traffic congestion, or a lack of real-time tracking. Monitoring this KPI enables businesses to benchmark performance, predict bottlenecks, and optimize delivery routes to reduce average delivery time, which directly improves customer satisfaction. Offering same-day delivery or next-day delivery is increasingly tied to how well a business manages this metric at scale.

Formula: Average Delivery Time = Total delivery time for all orders / Total orders delivered

Benchmark: Same-day and next-day delivery are becoming standard for urban e-commerce. In quick commerce (Q-Comm) markets, the benchmark has shifted from days to minutes, with 10 to 30-minute delivery windows now the norm in major urban centers.

5. Customer Satisfaction Score (CSAT) for Last-Mile Delivery

CSAT measures how happy customers are with their delivery experience. It is usually derived from post-delivery surveys or feedback forms that rate satisfaction levels.

High CSAT scores signal strong service quality and effective last-mile delivery strategies. Low scores may indicate recurring issues such as missed delivery windows, damaged goods, or lack of communication. CSAT directly influences customer loyalty and is a critical benchmark for enhancing the post-purchase experience.

Formula: CSAT = (Number of satisfied responses / Total survey responses) x 100

Benchmark: A CSAT score of 80% or higher is considered strong in logistics.

6. Return and Refusal Rate: How High Return Rates Hurt Last-Mile Profitability

This metric evaluates the percentage of deliveries that are returned by the customer or refused upon arrival. High return rates can disrupt delivery operations and inflate costs.

Tracking the reason behind returns — whether due to product issues, wrong deliveries, or delivery delays — helps improve delivery accuracy and reduce operational inefficiencies.

It also informs product quality improvements and sets the foundation for a better customer experience. Understanding reverse logistics processes is essential when this metric trends upward, as returns management directly affects overall logistics cost.

Formula: Return/Refusal Rate = (Returned or refused deliveries / Total deliveries) x 100

Benchmark: Keeping this below 5% is ideal for most ecommerce operations.

7. Delivery Accuracy Rate: What It Means and Why It Matters for Ecommerce

Delivery accuracy refers to the correct delivery of the right item to the right address at the right time. It captures how well your last-mile logistics perform under pressure.

Inaccurate deliveries result in re-delivery, refunds, or even brand damage. Maintaining high delivery accuracy ensures lower operational costs and higher customer satisfaction.

It is also a strong indicator of service quality and a reflection of how seamlessly your logistics system works. Businesses using robust delivery management software tend to report significantly higher delivery accuracy rates by automating address validation and driver assignment.

Formula: Delivery Accuracy = (Correct deliveries / Total deliveries) x 100

Benchmark: Target 98%+ for reliable last-mile operations.

8. Delivery Density: How to Maximize Deliveries Per Route

Delivery density refers to the number of successful deliveries made per delivery route or per unit of distance. It helps gauge the efficiency of your delivery operations over a geographic area.

Higher delivery density lowers cost per mile and improves fuel efficiency. It is especially important for urban logistics, where multiple deliveries in close proximity can maximize vehicle utilization.

Optimizing this KPI leads to better planning, less fuel consumption, and fewer labor hours. In quick commerce and hyperlocal delivery models, delivery density is calculated over much smaller geographic zones and tighter time windows, making it a fundamentally different metric than in traditional ecommerce fulfillment.

Formula: Delivery Density = Total deliveries completed / Total routes (or total distance covered)

Benchmark: Higher is better; urban routes should consistently outperform rural ones.

9. Fuel Efficiency Per Delivery: How to Track and Reduce Last-Mile Fuel Costs

Fuel efficiency measures the amount of fuel used per delivery or per mile. This KPI plays a direct role in calculating the total delivery cost and the environmental footprint of your last-mile logistics.

Monitoring and improving fuel efficiency through smart route planning, reduced idling, and regular vehicle maintenance results in cost savings and aligns with sustainability goals. It also boosts operational efficiency and supports long-term profitability. Businesses that invest in route planning and optimization software typically see the fastest gains in fuel efficiency across their fleet.

Formula: Fuel Efficiency = Total fuel consumed / Total deliveries (or total miles driven)

Benchmark: Track month-over-month trends; consistent improvement signals better route optimization.

10. Real-Time Tracking Accuracy: Why Shipment Visibility Drives Customer Trust

Real-time tracking accuracy evaluates how precisely the tracking data reflects the actual status and location of a shipment. This KPI is crucial for both customers and delivery teams.

Accurate tracking improves delivery transparency, reduces failed delivery attempts, and enhances customer trust. It also equips customer support teams with actionable information, reducing complaints and inquiries.

High tracking accuracy is a strong differentiator for modern delivery companies aiming to boost customer satisfaction. Businesses that deploy a branded tracking page alongside live carrier updates report measurable reductions in WISMO (Where Is My Order) inquiries.

Formula: Tracking Accuracy = (Correctly updated tracking events / Total tracking events) x 100

Benchmark: Aim for 99%+ accuracy to maintain customer trust and operational visibility.
