Calculate the ROI of fleet management on your fleet.
Enter the number of vehicles, kilometres, consumption and operating costs to estimate how much idle time, administrative activities and maintenance weigh. The simulation shows a range, so you can evaluate the levers before requesting a quote.
- Free simulationGet an indicative range immediately, without submitting a form.
- Minimum dataLittle information about the fleet is enough.
Estimate the potential savings of your fleet.
Enter the number of vehicles for a quick estimate, or open the advanced mode to refine kilometres, consumption, idle time, administrative hours and maintenance costs.
How fleet ROI calculation works.
The simulation separates fuel and idle time, administrative tasks and preventative maintenance, so you can see which factors impact the most.
The estimate combines three separately calculated components: fuel and idle time, administrative efficiency and preventive maintenance. Safety and compliance are described separately because their impact depends on processes, configuration and operational context.
Cost factors considered
The quick estimate uses default values for annual kilometres, average consumption, fuel price, idle time, administrative hours and maintenance cost. Advanced mode allows you to replace them with your real data.
- Number of vehicles (only mandatory data)
- Average annual kilometres per vehicle
- Average fuel consumption and cost
- Percentage of idle time
- Monthly administrative hours dedicated to the fleet
- Annual maintenance cost
How to read the result
The result always shows a range (minimum, middle, maximum) for category and for the total, never a single number presented as certain.
- Minimum, middle and maximum estimate for each category
- Monthly and annual value
- Calculation parameters visible and editable where applicable
ROI calculator parameters
The quick simulation starts from the initial values shown below. By opening the advanced mode you can replace the main parameters with your fleet data and obtain an estimate that is more in line with your context.
| Savings area | Parameter | Initial value | Simulated range | Customizable |
|---|---|---|---|---|
| Fuel and idling | kilometres per year per vehicle | 25000 km/year per vehicle | 15000–45000 km/year per vehicle | Yes, in advanced mode |
| Fuel and idling | Average consumption | 9.5 L/100km | 6–16 L/100km | Yes, in advanced mode |
| Fuel and idling | Average fuel price | 1.7 EUR/L | 1.55–1.85 EUR/L | Yes, in advanced mode |
| Fuel and idling | Share of fuel used while idling | 12 % of fuel cost attributed to idling | 8–18 % of fuel cost attributed to idling | Yes, in advanced mode |
| Fuel and idling | Simulated reduction in idle time | 30 % of idle time that can be reduced with Zenit alerts | 15–45 % of idle time that can be reduced with Zenit alerts | No, scenario parameter |
| Administrative efficiency | Monthly administrative hours per vehicle | 0.6 administrative hours/month per vehicle | 0.3–1.2 administrative hours/month per vehicle | Yes, in advanced mode |
| Administrative efficiency | Administrative hourly cost | 25 EUR/hour | 18–35 EUR/hour | Yes, in advanced mode |
| Administrative efficiency | Administrative time recovered in the scenario | 20 % of recoverable administrative hours | 10–30 % of recoverable administrative hours | No, scenario parameter |
| Preventive maintenance | Annual maintenance cost per vehicle | 1800 EUR/year per vehicle | 1200–2600 EUR/year per vehicle | Yes, in advanced mode |
| Preventive maintenance | Avoidable share of maintenance costs in the scenario | 15 % of preventable maintenance cost | 8–25 % of preventable maintenance cost | No, scenario parameter |
Do you prefer to talk about it directly with the team?
If you don't want to use the calculator, share the context of your fleet and the Zenit team prepares a personalized estimate for you to comment on together.
- No commitmentThe request does not trigger fees or automatically create an account.
- No sensitive dataIndicative data on the fleet is enough.
Frequently asked questions about ROI estimation.
Clarifications on the binding nature of the estimate, required data and next steps.
Is the estimate binding?
No, it is indicative and based on the data you share: the real proposal is defined with a consultant.
What data do you need to receive an estimate?
All you need is the number of vehicles, average mileage and an estimate of the administrative time dedicated today to fleet management, no sensitive data.
What happens after receiving the estimate?
You can book a demo to learn more about how the numbers actually apply to your fleet, without obligation.
Bring this estimate into a conversation with an advisor.
After receiving the estimate, you can request a recommended demo based on the same data.
