A Guide to the Last Mile Delivery Metrics Your Business Should Track

For Australian distributors, the fleet of delivery vehicles in the yard represents a massive daily investment in capital, fuel, and wages, impacting the overall delivery cost. But is that investment generating profit or slowly eroding it? The difference comes down to the performance measures you track.

With the Australian last mile delivery market projected to grow exponentially to $7.74 billion AUD by 2034, getting control of your logistics and delivery efficiency is no longer optional. This guide provides a clear framework for turning your dedicated delivery services from a source of stress into a powerful competitive advantage by focusing on the nine crucial delivery metrics that matter most.
Here, you’ll find actionable steps to measure and improve:

• On-Time Delivery Rates
• Delivery Success Rate
• Cost Per Delivery
• Driver Retention
• Average Service Time
• Fuel Consumption and Mileage
• Damage Claims Rate
• Capacity Utilisation
• Customer Feedback

1. On-Time Delivery: The Ultimate Measure of Your Promise

Why does a 94% on-time delivery rate feel so much worse to a customer than a 97% rate? Because every late delivery is a broken promise that erodes trust and lowers customer satisfaction. This core metric is the foundation of customer retention, as it directly measures your reliability and tells your most valuable clients whether they can depend on your delivery performance.

How to Measure It

Track the percentage of deliveries that arrive within the promised time window. The formula is: (Total On-Time Deliveries / Total Deliveries) x 100 = On-Time Delivery %.

Aim for a benchmark of 95% or higher to maintain strong client loyalty. A delivery performance rate consistently below 90% often points to a deeper issue that needs attention before it impacts key accounts.

A 3 Step Plan to Improve On-Time Delivery

1. Find Your “Delay Hotspot”: For one week, ask your drivers to log the single biggest cause of their delays. You’ll quickly find “bad traffic” is often a predictable bottleneck at a specific roundabout at 3 PM, or a particular customer’s receiving dock is always clogged in the morning.
2. Fix the Bottleneck: Once you identify the specific problem, you can take specific action. This could mean altering the delivery route or working with that customer to shift their delivery time to the afternoon.
3. Widen Windows to Guarantee Promises: A wider, reliable delivery window is always better than a narrow, broken one. Promising a 9 AM to 12 PM window that you hit 98% of the time builds more trust than an 8 to 10 AM window you only hit 80% of the time.

This shifts your focus from the vague problem of “traffic” to solving specific, controllable issues. It’s the first step in turning your delivery performance from a source of customer complaints into a reason they stay loyal, boosting customer satisfaction.

2. Delivery Success Rate: Eliminating the “Triple Cost” of Failure

While On-Time Delivery measures your promise, delivery success measures your execution. A failed delivery isn’t just an inconvenience; it’s a financial drain that silently eats into your margins. You pay for the initial trip, the return trip, and the second attempt, effectively tripling the cost for a single order. Minimising failed delivery attempts is key.

Insight: The Last Mile Delivery Accounts For Over Half Your Total Shipping Cost

According to data from Statista, the final stage of delivery is by far the most expensive. Why? It’s a game of density. Long haul transport is efficient because one truck moves hundreds of orders. The last mile delivery is complex and has a high cost because one driver handles only a few. This makes every failed delivery attempt disproportionately damaging to your profitability.

How to Measure and Improve It

Your benchmark should be 98% or higher. For perishable goods, anything less is unacceptable due to spoilage and your obligations under Australian Consumer Law.

1. Diagnose the “Why”: For one week, categorise every failed delivery. The main culprits are usually “Recipient Not Available,” “Incorrect Address” (a failure of delivery accuracy), or “Site Access Denied.”
2. Create “Customer Delivery Profiles”: For your top 10 most complex delivery locations, create a simple, one page profile. Include the specific contact person for receiving, their direct phone number, any restricted delivery hours, and a photo of the correct loading dock entrance.

By formalising this knowledge, you build a reliable delivery system that prevents costly failures and improves efficiency, protecting your profit margins on every single run.

3. Cost Per Delivery: Uncovering Your True Profitability

Now that we’ve addressed the costs of failed deliveries, it’s time to uncover the true cost of the successful ones. Are you accidentally losing money on your biggest customers? Without knowing your true Cost Per Delivery, it’s impossible to say. This single key performance indicator is a key metric for understanding your operational health and the overall cost of your delivery operation.

How to Calculate Your “Fully Loaded” Cost Per Delivery

The goal is to capture every expense related to putting one vehicle from your delivery fleet on the road for one month. Use your own data, but here’s a realistic example for a standard 2 tonne van:

• Driver Wages & Costs: (~$75k annual package) = $6,250/month
• Vehicle Depreciation or Lease: (~$60k vehicle over 5 years) = $1,000/month
• Fuel: (~2,500 km/month at 12L/100km and $1.80/L diesel) = $540/month
• Insurance & Registration: = $350/month
• Maintenance & Tyres: = $250/month
• Management Overhead: (A manager’s time on routing, compliance, etc.) = $850/month

Total Estimated Monthly Cost Per Vehicle: ~$9,240

If that vehicle completes 500 deliveries a month, your true Cost Per Delivery is: $9,240 / 500 = $18.48.
This number becomes your financial North Star, giving you the clarity to make confident decisions on pricing, route efficiency, and future investments for your delivery optimisation.

4. Driver Retention: Protecting Your Most Valuable Asset

Knowing your financial costs is critical, but the human cost of losing a good driver can be even higher. Boosting driver satisfaction is essential. With a shortage of over 28,000 truck drivers in Australia, keeping your best people is a core operational strategy. An experienced driver’s route knowledge is an invaluable asset that is difficult and time consuming to replace.

“An experienced driver knows the shortcuts, the receiving dock managers, and the tricky delivery points. That ‘tribal knowledge’ is an invaluable asset. Losing it costs far more than just recruitment fees; it costs you efficiency and customer relationships. Retention isn’t an HR issue; it’s a core operational strategy.”

— Walter Scremin, CEO of Ontime Delivery Solutions

How to Improve Retention by Removing Friction

The best drivers rarely leave for a few extra dollars; they leave because of consistent, daily frustrations.

1. Conduct “Stay Interviews”: Don’t wait for the exit interview. Once a quarter, sit down with your best drivers and ask two simple questions: “What is the most frustrating part of your day?” and “If you had a magic wand, what one thing would you change?”
2. Fix One Thing, Visibly: You do not have to solve every problem. Pick one common frustration, such as a difficult delivery route, a slow handheld scanner, or confusing paperwork, and fix it. The act of listening and taking visible action builds more loyalty than a pay rise.

This process makes your drivers feel respected and heard, which is the key to improving retention and protecting the invaluable knowledge that keeps your operation running smoothly.

5. Average Delivery Time: Winning the Battle at the Doorstep

After ensuring you have the right people on the road, the next opportunity for efficiency is in the process itself. In last mile delivery, speed isn’t about driving faster; it’s about “stopping faster.” The greatest gains in efficiency are found in the time between the driver turning off the engine and completing the delivery drop.

How to Measure and Improve It

Your benchmark for urban routes, measured via GPS timestamps, should be 6 to 8 stops per hour.

A powerful technique is “Reverse Loading.” The rationale is simple: a driver’s time is most expensive when they are stationary but working. Your warehouse team can load the vehicle in the reverse order of the delivery run, so the first delivery package is loaded last, right at the doors.

Saving just two minutes searching for a package at each stop, across 30 stops, gains an hour of extra capacity per day. This allows you to increase revenue and scale your business without needing to add more vehicles to your fleet.

6. Fuel Consumption and Mileage: Eliminating “Empty Miles”

Time optimisation at the stop is crucial, and so is optimising time on the road. With fluctuating diesel prices, every kilometre driven without purpose is a direct hit to your profit. The goal is to maximise “revenue miles” and eliminate “empty miles” from each mile delivery by reducing backtracking.

“Modern logistics isn’t about driving faster; it’s about driving smarter. The biggest gains in fuel efficiency don’t come from the vehicle, but from the route plan. Eliminating just 10% of unnecessary ’empty miles’ through smart zoning can directly add several percentage points to a company’s net profit margin.”

— Chloe Jensen, Senior Logistics Analyst, ANZ Supply Chain Institute

A 2-Step Plan to Cut Fuel Waste

1. Zone Your Deliveries: Group all of tomorrow’s delivery runs by postcode using a simple mapping tool. This visual representation will immediately reveal any inefficient, crisscrossing delivery routes.
2. Schedule by Zone: Manage customer expectations to enable greater efficiency. Instead of offering delivery everywhere, every day, schedule specific days for specific delivery zones (e.g., Northern suburbs on Monday and Wednesday, Western on Tuesday and Thursday).

This forces load consolidation and can reduce backtracking by up to 20%, giving you a systematic way to lower your largest variable cost and protect your profit margin from fuel price shocks.

7. Damage Claims & Order Accuracy Rate: Protecting Your Reputation

An efficient delivery is only successful if the goods arrive intact. A damaged delivery, much like a failure in order accuracy, is more than a financial cost; it’s a failure that erodes customer trust. This important metric helps you measure and protect your brand’s reputation for quality delivery.

A 3-Step Framework to Reduce Damage

1. Diagnose the “Why”: For one month, categorise every single damage claim related to a delivery. Is the root cause improper loading, poor packaging, or in transit shifting? You cannot treat the problem until you diagnose it.
2. Create One Page Visual Guides: A helpful tool is to create simple, one page visual guides for handling your top 3 most damaged items and place them at the packing bench and loading dock.
3. Close the Feedback Loop: Review the damage claim log in your weekly team meeting, not just in an annual performance review. This makes damage reduction an active, shared responsibility.

This systematic approach addresses the root causes of damage, helping you protect your brand’s reputation, avoid replacement costs, and maintain hard won customer trust.

8. Capacity Utilisation: Stop Paying to Ship Air

Just as important as protecting the goods inside the truck is making sure the truck itself is the right size for the delivery job. Sending out a half empty vehicle is one of the most common and invisible ways that logistics departments burn cash. The goal of this optimisation is to match the asset to the task every single day.

The 3-Step Fleet Utilisation Review

• The Daily Spot Check: At the end of each day, have your dispatcher identify and log the single most poorly utilised run (e.g., “The 4 tonne truck on the Northern run was only 30% full”).
• The Weekly Rebalance: Every Friday, review the week’s logs. If the same delivery run was consistently half empty, reassign a smaller, cheaper to run vehicle to it for the following week.
• The Quarterly Fleet Review: Every 90 days, analyse the long term trends. Do you consistently have too much large vehicle capacity? Is a smaller van a better investment than another truck?

This simple cadence ensures you are always aligning your vehicle costs with your revenue, so you can stop paying for empty space and maximise the delivery performance and profitability of every run.

9. Customer Feedback & Satisfaction: Your Ultimate Performance Indicator

After optimising all your internal processes, the final metric for customer satisfaction comes from the most important source: your customer. For many business to business clients, particularly in wholesale and distribution, your driver is the only human face of your company. A great delivery experience builds loyalty that marketing never could.

A Simple Framework for Actionable Feedback

1. Ask the Right Question: A more effective approach than asking if a delivery was “good” is to incorporate one specific question into your surveys, such as “How would you rate the professionalism of our driver on a scale of 1-5?”
2. Treat “Where Is My Order?” as a System Failure: This common call isn’t a customer service issue; it’s a symptom of an information gap. It signals that your customer feels anxious due to a lack of delivery visibility. The most effective way to solve this problem is by proactively providing transparency through real time delivery tracking updates.

With nearly 8 in 10 shoppers linking delivery to overall customer satisfaction, focusing on the delivery experience is key to building unbreakable customer loyalty and freeing up your internal team’s time to focus on growth.

Last Mile Delivery Metrics: Frequently Asked Questions

What is the most important last mile delivery metric to track first?

For most businesses, the best place to start from all the mile delivery metrics is On-Time Delivery. It directly measures your delivery promise to the customer and has the biggest immediate impact on customer satisfaction and retention. While Cost Per Delivery is crucial for financial health, On-Time Delivery is the primary indicator of operational delivery performance quality.

How does On-Time Delivery differ from Delivery Success Rate?

On-Time Delivery measures timeliness, whereas delivery success measures completion. An order can be a successful mile delivery (delivered to the right place) but still fail the On-Time Delivery metric if it arrives late. Conversely, a delivery attempt can be on time but fail the success metric if the recipient isn’t available, resulting in a return trip.

Why is Cost Per Delivery a more accurate metric than just tracking fuel and wages?

Cost Per Delivery is a more accurate key performance indicator because it provides a “fully loaded” figure. Simply tracking fuel and wages ignores significant operational expenses like vehicle depreciation, insurance, registration, maintenance, and management overhead. Including these provides a true picture of profitability for each delivery, highlighting opportunities for route optimization and preventing hidden losses on seemingly profitable routes, boosting efficiency.

Can improving driver retention directly impact logistics costs?

Yes, absolutely. High driver retention directly reduces costs in three key areas: it eliminates recruitment and training expenses, experienced drivers are more efficient with delivery routes and service times (improving delivery time and lowering fuel and labour costs per stop), and they make fewer errors, which are important measures that reduce the costs associated with failed deliveries and damage claims.
