Total cost (TCO) and ROI calculator
Published by Keonex, a manufacturer and implementer of electronic shelf labels. How we work and why we say so: methodology and transparency.
This calculator estimates the total cost of an electronic shelf label project over the period you choose and compares it with renting. Every assumption is visible and editable, and the calculation runs in your browser: no data is sent anywhere.
It is meant to structure a conversation with vendors, not to replace a quote. If you do not have a figure, leave it at zero rather than inventing one.
The starting values are placeholders so you can see how the calculation works; they are not market prices or any vendor’s prices. Replace them with the figures from your quotes.

How it is calculated
- Investment = labels × price + gateways × price + labels × installation + fixed costs.
- Recurring = software per store per year + support (% of hardware per year) + battery replacement when battery life is shorter than the horizon, all over the chosen horizon.
- Savings = paper price-change time minus ESL time, multiplied by the hourly cost, plus savings from avoided errors. Time scales per 100 labels.
- Rental = fee × labels × months + services per store per year. It is compared with the purchase TCO before savings.
- It excludes taxes, financing, volume discounts, residual value of equipment and revenue from dynamic repricing.
