ROI Calculator: Measuring the Financial Impact of Route Optimisation

The cost side: what route optimisation actually costs

The direct cost is straightforward - a monthly or annual software subscription, typically priced by fleet size or route volume. The indirect cost is smaller than most operations expect: address data cleanup (a one-time effort), a short adjustment period for planners and drivers, and occasional manual override of routes for real-world exceptions the software can't anticipate. There's no hardware to buy and no significant IT overhead for a cloud-based tool.

The savings side: the three levers that actually move

Almost all of the financial return from route optimisation comes from three places:

• Fuel savings - directly proportional to the reduction in total miles driven
• Labour savings - fewer driving hours per route, or more deliveries completed per shift at the same labour cost
• Fleet utilisation - handling the same delivery volume with fewer vehicles, or the same fleet handling more volume, deferring the cost of buying another vehicle

A worked example

Take a small fleet driving 500 miles a week, at a combined fuel-plus-maintenance cost of roughly $0.65 per mile (a reasonable planning estimate; your real number will vary by vehicle and local fuel prices) and a driver cost of $25/hour. Suppose route optimisation removes 15% of those miles - a conservative outcome for a fleet that was previously routing manually, well below the 10-30% range commonly seen in genuinely inefficient starting points.

That's 75 fewer miles a week, or roughly $49 in direct vehicle cost. If those miles also represent about two fewer hours of driving time across the fleet, that's another $50 in labour cost, for a combined weekly saving in the neighbourhood of $100 - about $5,200 a year, before counting the planner time saved by not manually sequencing routes every morning. Whether that clears a specific software subscription's cost is simple arithmetic once you have your own mileage and labour numbers - the point of walking through the calculation is that it's worth doing with your actual data rather than trusting a headline percentage. For what the subscription side costs, see our route planning software cost guide.

Building your own calculation

To estimate your own ROI, you need four numbers you likely already have or can pull quickly:

• Current weekly or monthly mileage across your fleet
• Your all-in per-mile cost (fuel plus maintenance is a reasonable estimate if you don't track this precisely)
• Average driver hourly cost
• A conservative estimate of your mileage reduction - if you're not sure, run one real route through an optimiser and compare it to your current plan rather than guessing

The honest caveat

If your routes are already short, simple, and well-planned, the available savings will be smaller and the payback period longer - that's a legitimate outcome, not a flaw in the calculation. The value of doing this exercise with your own numbers, rather than accepting a vendor's stated average, is that it tells you the truth about whether route optimisation is worth adopting for your specific operation, not a hypothetical one.
