Delivery cost per parcel is the total cost of getting one package from your depot to the customer's door. It is the single most important number in a delivery operation because it determines whether each delivery makes money or loses it.
The basic formula:
Cost Per Parcel = Total Delivery Costs / Total Parcels Delivered
The challenge is not the formula. It is knowing what goes into "Total Delivery Costs." Most delivery businesses undercount their costs because they track fuel and driver wages but miss vehicle depreciation, failed delivery expenses, and the time their dispatcher spends planning routes.
What Costs Go Into Delivery Cost Per Parcel?
Break your total delivery costs into five categories:
1. Fuel
The most visible cost, but rarely the largest. To calculate:
- Track total fuel spend per vehicle per month (fuel cards make this easy)
- Divide by the number of parcels that vehicle delivered
For a van averaging 12L/100km in urban delivery driving, at AUD 1.80/L (mid-2026 Australian average), covering 120 km per day:
120 km x 12L/100km = 14.4L x AUD 1.80 = AUD 25.92/day in fuel
If that van delivers 40 parcels per day:
AUD 25.92 / 40 = AUD 0.65 per parcel in fuel
2. Labour
Usually the largest single cost component. Include:
- Driver wages (hourly or daily rate)
- Superannuation / employer contributions (11.5% in Australia as of 2026)
- Workers' compensation insurance
- Dispatcher/planner time (pro-rated across total deliveries)
Example for one driver at AUD 28/hour, 8-hour shift:
AUD 28 x 8 = AUD 224/day Plus 11.5% super: AUD 224 x 1.115 = AUD 249.76 Plus workers' comp (~3% of wages): AUD 249.76 x 1.03 = AUD 257.25
If this driver delivers 40 parcels:
AUD 257.25 / 40 = AUD 6.43 per parcel in labour
Add dispatcher cost. If one dispatcher (AUD 65,000/year fully loaded) manages 5 drivers doing 200 total deliveries per day:
AUD 65,000 / 250 working days = AUD 260/day AUD 260 / 200 deliveries = AUD 1.30 per parcel in dispatch labour
3. Vehicle costs
These are easy to forget because they do not appear as a daily expense. Include:
- Lease payments or depreciation (purchase price / expected years of service)
- Registration and insurance
- Servicing and maintenance (tyres, brakes, oil changes)
- Tolls (if applicable to your delivery area)
Example for a leased van at AUD 600/month:
AUD 600 / 22 working days = AUD 27.27/day AUD 27.27 / 40 deliveries = AUD 0.68 per parcel
Insurance at AUD 2,400/year:
AUD 2,400 / 250 days = AUD 9.60/day AUD 9.60 / 40 deliveries = AUD 0.24 per parcel
Maintenance budget at AUD 3,000/year:
AUD 3,000 / 250 days = AUD 12/day AUD 12 / 40 = AUD 0.30 per parcel
Total vehicle: AUD 0.68 + 0.24 + 0.30 = AUD 1.22 per parcel
4. Technology
Software subscriptions, driver phones/data plans, and any API costs:
- Route optimization software: varies, typically AUD 50 to 200 per vehicle per month
- Driver phone/data: ~AUD 50/month per driver
- Any per-transaction API costs (SMS notifications, mapping)
Example at AUD 150/month for software + AUD 50/month for phone:
AUD 200 / 22 days = AUD 9.09/day AUD 9.09 / 40 deliveries = AUD 0.23 per parcel
5. Failed delivery costs
The cost most businesses do not track but should. When a delivery fails:
- The driver has already spent time and fuel to reach the address (sunk cost)
- A redelivery attempt doubles the stop cost
- Customer service time is spent investigating and rescheduling
The average cost of a failed delivery is USD 17.78 (Loqate). If your failure rate is 5% on 200 daily deliveries, that is 10 failed deliveries per day.
10 x USD 17.78 = USD 177.80/day in failed delivery costs USD 177.80 / 200 total deliveries = USD 0.89 per parcel
This cost gets allocated across all parcels, because the failed ones still consumed resources.
Putting It All Together: Sample Calculation
For a fleet of 5 drivers in Sydney, each delivering 40 parcels per day (200 total):
| Cost category | Per parcel |
|---|---|
| Fuel | AUD 0.65 |
| Driver labour | AUD 6.43 |
| Dispatch labour | AUD 1.30 |
| Vehicle (lease + insurance + maintenance) | AUD 1.22 |
| Technology | AUD 0.23 |
| Failed deliveries (5% rate) | AUD 1.10 |
| Total cost per parcel | AUD 10.93 |
Your numbers will be different. The point is to capture all five categories, not just the obvious ones.
Why Your Cost Per Parcel Matters More Than Total Costs
Total monthly delivery spend tells you how much money left your account. Cost per parcel tells you whether your operation is getting more efficient or less efficient as you grow.
Consider two months:
- Month 1: AUD 45,000 total cost, 4,200 deliveries = AUD 10.71 per parcel
- Month 2: AUD 52,000 total cost, 5,100 deliveries = AUD 10.20 per parcel
Total costs went up by AUD 7,000 (alarming). But cost per parcel went down by AUD 0.51 (good). You are spending more because you are delivering more, and you are doing it more efficiently. Without the per-parcel number, you only see the first half of the story.
How to Reduce Your Cost Per Parcel
Increase drop density. More deliveries per route means each delivery shares the fixed costs (vehicle, insurance, dispatch) across a larger base. Grouping deliveries by geographic zone and scheduling pickup/drop windows to cluster volumes are the simplest levers.
Reduce failed deliveries. Every failed delivery is paid for twice: once when the driver attempts it, and again when they reattempt. Reducing failure rate from 8% to 3% on 200 daily deliveries saves roughly 10 reattempt trips per day. Automated customer notifications with live tracking links are the most effective tool for this.
Optimize routes. A 15% reduction in total driving distance reduces fuel costs proportionally and lets drivers complete more stops in the same shift. Route optimization software typically pays for itself within the first month by reducing the fuel and overtime line items. (See: What Is Route Optimization?)
Right-size your vehicles. A large van costs more in fuel and lease than a small van. If most of your parcels fit in a hatchback, running a Sprinter-class van burns money on unused capacity. Match vehicle size to typical load.
Track and benchmark monthly. Cost per parcel only works as a management tool if you track it consistently. Calculate it monthly, broken down by cost category, and look for which categories are growing faster than your delivery volume.
Tools like iDirect provide delivery analytics that automatically calculate cost-per-delivery metrics across your fleet, removing the spreadsheet work from the tracking process.
Common Benchmarks
Cost per parcel varies significantly by geography, delivery type, and scale. As a rough guide for Australian last mile delivery operations:
| Fleet size | Typical cost per parcel |
|---|---|
| 1 to 3 vehicles (owner-operator) | AUD 8 to 15 |
| 5 to 10 vehicles | AUD 6 to 10 |
| 10 to 25 vehicles | AUD 4 to 8 |
| 25+ vehicles | AUD 3 to 6 |
These ranges assume standard parcel delivery in metropolitan areas. Specialty deliveries (temperature-controlled, bulky items, time-critical medical) will be higher. Rural deliveries with long distances between stops will also push costs up.
If your cost per parcel is significantly above the range for your fleet size, the breakdown by category will show you where the excess sits.
Frequently Asked Questions
Should I include overhead (rent, admin staff) in cost per parcel? It depends on what you are using the number for. For operational benchmarking (am I getting more efficient?), use direct delivery costs only: fuel, driver labour, vehicle, technology, failed deliveries. For pricing (how much should I charge per delivery?), include allocated overhead so you know your true breakeven point.
How often should I calculate cost per parcel? Monthly is sufficient for most operations. Calculate it more frequently (weekly) if you are making significant changes to routes, fleet size, or pricing. Less frequently than monthly and you lose the ability to catch problems early.
What is a good cost per parcel? There is no universal answer. A flower shop delivering 30 arrangements per day in a single suburb will have a different cost structure than a courier running 500 parcels across a metro area. The useful comparison is your own cost per parcel over time: is it going down, staying flat, or going up?
Does cost per parcel change with scale? Yes. The fixed cost components (vehicle, insurance, technology, dispatch) are spread across more deliveries as volume grows, so cost per parcel typically decreases with scale. However, if growth requires adding vehicles or drivers, costs step up before the new capacity is fully utilised. This is why tracking cost per parcel through growth periods is important.
Should I share cost per parcel data with my team? Yes. When drivers understand that a failed delivery costs AUD 17 and that their route efficiency directly affects the number, they make better decisions at each stop: parking closer, calling ahead when running late, following safe-drop procedures.
