Cost per mile measures the vehicle. Cost per stop measures the business. For a delivery or service operation, it is the more useful of the two, because the stop is the unit of value delivered.
The calculation
`` Cost per stop = total route cost ÷ completed stops ``
Where total route cost includes:
- Driver cost, fully loaded, including on-costs and overtime
- Vehicle cost — fixed allocation plus variable running cost
- Fuel
- An allocation of depot, planning and dispatch overhead
- Loading and preparation cost
Two decisions materially affect the result and must be stated:
Completed or attempted stops? Use completed. Cost per attempted stop flatters an operation with a poor first-time delivery rate, which is exactly the operation that needs the number.
Which overheads? Direct operational overhead — planning, dispatch, depot — is defensible. Corporate overhead is usually better excluded, or shown separately.
A single fleet-wide cost per stop is nearly useless. Urban dense, suburban and rural routes have structurally different economics, and averaging them hides both the opportunity and the problem.
What drives it
`` Cost per stop ≈ cost per route hour ÷ stops per hour Stops per hour ≈ 60 ÷ (service time + inter-stop travel time) ``
So there are exactly three levers: the cost of an hour, the service time, and the travel between stops. Everything else in delivery operations is a means of moving one of these.
| Lever | Mechanism |
|---|---|
| Route density | More stops per mile; the dominant factor |
| Service time | Access improvements, better equipment, process |
| Time windows | Narrower windows reduce stops per hour |
| Vehicle utilisation | Fuller vehicles mean fewer routes for the same work |
| First-time delivery | Failures create a second stop for the same revenue |
| Driver cost | Wage rates, overtime, shift structure |
| Route planning quality | Sequencing and assignment |
Using it commercially
Pricing. Delivery charges, minimum order values and service fees should relate to the cost of the stop. Businesses that price purely on product margin subsidise their most expensive customers with their cheapest.
Window pricing. If a two-hour window costs meaningfully more per stop than a four-hour window, that difference has a price. See time windows.
Frequency decisions. The trade between delivery frequency and drop size becomes arithmetic once you know the cost of a stop.
Network design. Whether to open a depot, use a satellite, or subcontract an area is answerable in cost per stop terms.
Make or buy. Comparing your cost per stop against a third-party carrier's price is the fundamental outsourcing question — provided you compare like with like, including the service level and the cost of failures.
Benchmarks and their limits
External benchmarks are of very limited use here. A parcel operation delivering 130 stops a day and a foodservice distributor delivering 22 large drops have entirely different cost structures, and both are legitimate.
Useful comparisons are internal:
- Between depots serving similar geography
- Between density bands within your own operation
- Against your own trend over time
- Between your best-performing routes and your average — the internal top-quartile comparison is usually the most actionable analysis available
Improving it
In rough order of return for most operations:
- Density. Delivery day consolidation, territory redesign, clustering by area. The largest structural lever.
- First-time delivery rate. Every failure is a stop paid for twice.
- Service time. Access improvements, pre-notified access instructions, better equipment at the stop, and removing waiting time.
- Window policy. Widening windows where customers do not genuinely need them.
- Route planning quality. Sequencing, assignment and realistic service times.
- Vehicle utilisation. Right-sized vehicles for the work, fuller loads.
- Shift structure. Matching driver hours to route length rather than to a standard shift.
Frequently asked questions
What is a typical cost per stop?
It varies so widely by density, drop size and service model that a general figure would be misleading. Calculate your own, segment it by density band, and track the trend — that is where the value is.
Should failed deliveries count as stops?
Not in the denominator. Count completed stops, so that failures correctly increase your cost per successful delivery. Report the failure rate separately, since it is a key driver of the number.
How does cost per stop relate to cost per mile?
They measure different things and both are useful. Cost per mile tells you about vehicle efficiency; cost per stop tells you about business efficiency. A route that reduces miles while reducing stops per hour can improve one and worsen the other.
Can we use cost per stop to price customers?
Yes, and it is the correct basis for delivery charges, minimum orders and service fees. Combine it with cost-to-serve analysis to account for frequency, service time and non-delivery costs per customer.
What is the fastest way to reduce cost per stop?
Usually improving first-time delivery rate, because it requires no structural change and each avoided failure removes a complete stop from your cost base. Density improvements deliver more in the long run but require territory or frequency changes.
