What is return on investment in digital signage and how to define success
Return on investment in digital signage is the ratio between the business value generated and the total cost of the signage system over time. In simple terms, it measures how much economic value was created for every shekel invested. True success in digital signage is not measured solely by the aesthetic appearance of the screen.
Success can include an increase in sales and revenue, savings in operating costs such as printing, shorter service times, a reduction in operational errors, improved customer experience metrics or improved workflow. The clear conclusion is that “looking good” alone is not a sufficient definition of success when it comes to a business investment.
How to calculate ROI in digital signage using a simple formula
The basic formula for calculating ROI is fairly simple: ROI = (total benefit – total cost) / total cost x 100. The financial benefit includes additional revenue and cost savings, while the cost includes the initial investment and all ongoing expenses.
It is important to calculate ROI over a defined period, usually one or three years, in order to get a full picture. You should distinguish between CAPEX (one-time expenses) and OPEX (ongoing expenses) and include both in the total cost (TCO) calculation. The purpose of this distinction is to prevent self-deception in assessing signage viability.
When the simple formula misleads signage viability
The simple formula can be misleading in several situations. There is significant difficulty in attributing specific sales to digital signage alone, especially when there are additional factors influencing the results. Seasonal effects or external promotions can distort the picture and are not always related to the screen.
In cases where there is no direct sale, such as information screens in a lobby or waiting areas, the simple formula is insufficient and more sophisticated measurement methods should be used that translate indirect benefits into monetary value.
What is the difference between ROI and payback period
Payback period refers to the time it takes for an investment to pay back, meaning the breakeven point at which revenues have covered the initial costs. This is an important metric but fundamentally different from ROI.
Payback answers the “when” question of covering the investment, while digital signage ROI answers the “how much” question of profit or value achieved relative to the investment. It is possible to recoup an investment quickly with a short payback yet generate a low ROI over time if ongoing costs are high or benefits diminish, and vice versa.
How long does it take for digital signage to pay for itself
Payback period varies greatly and depends on two main value drivers: consistent operational savings and a measurable increase in revenue. The payback can range from a few months to several years, depending on the nature of the business and how the screens are used.
Screens that replace solutions involving frequent printing and replacement, such as menus, promotions and rotating notices, tend to return the investment more quickly. Placing screens at points of interest that drive purchase decisions, such as near checkouts, in busy queues or beside specific shelves, also significantly shortens the payback period.
What most affects payback time
Screen placement is a critical factor: is it in a strategic location exposed to the right target audience and influencing decisions? Content update frequency also plays a decisive role, because stale content stops generating interest and benefit. High installation and maintenance costs without supporting benefits extend the payback, and the ability to reliably measure the screen’s impact on sales or savings is essential for accurate calculation.
Which costs must be included in the TCO calculation to understand signage viability
Most mistakes in calculating signage viability are caused by failing to account for all cost components over the project lifetime. It is important to include both the setup costs and the ongoing costs, including operations, content and maintenance.
Common “forgotten” costs include content creation such as design, photography and editing, connectivity and networking, employee time for operations and updates, electricity, maintenance and wear costs. Ignoring these costs leads to an inaccurate total cost (TCO) calculation and to flawed decisions.
CAPEX one-time costs – what is included
Setup costs include screens (purchase or leasing), stands and mounts, professional installation and hanging services, media players and initial operating software, infrastructure costs such as wiring and outlets, as well as initial planning and consulting.
OPEX ongoing costs – what is included
Operating costs include licensing for the content management system and software, electricity consumption of the screens and players, maintenance and repair costs, ongoing content creation and updates, system operations and administration time, and insurance.
| Component | What it includes | How to measure | Frequency | Common mistake |
|---|---|---|---|---|
| Screens and installation | Purchase cost and physical connection | Invoice cost + labor hours | One-time | Underestimating installation complexity |
| Software and licensing | Operating and content management software | Monthly or annual subscription fees | Monthly or annual | Not budgeted for in advance |
| Content creation | Design, copywriting, media | Labor hours or project cost | Variable | Underestimating the cost and time required |
| Electricity | Device consumption | Cost per kWh multiplied by operating hours | Monthly | Not considered significant |
| Maintenance | Routine checks, cleaning, repairs | Service cost and spare parts | Annual or as needed | Assuming nothing will break |
| Print savings | Previous printing costs | Print cost + shipping + employee time | Monthly | Failing to factor in all components |
How to calculate financial benefit when there is no direct sale from the screen
In situations such as screens in a lobby, in clinics, at service stations or in waiting areas, ROI is measured through benefits that translate into savings or monetary value. These include saving time for staff and customers, reducing congestion and queues, decreasing errors, and improving key performance indicators (KPIs) for customer satisfaction.
For example, fewer questions for service representatives equates to freeing up time to handle more complex cases, which means greater throughput or less need for additional staffing. Reducing perceived waiting time leads to higher customer satisfaction, less customer churn and a better reputation. A study published in Journal of Retailing and Consumer Services showed that digital signage in waiting areas improves satisfaction and reduces perceived waiting time.
Which KPIs are most important for measuring ROI in digital signage
Key performance indicators (KPIs) are specific, quantifiable and relevant metrics, and therefore are essential for measuring screen effectiveness. The chosen KPIs depend on the business goal of the signage.
For sales: an increase in sales of a promoted product, an increase in average basket size, conversions from a QR code or coupon. For savings: print savings and material costs, employee time savings. For customer experience: reduced dwell time in queues, improved satisfaction metrics, fewer complaints. It is recommended to choose 3-5 focused KPIs per goal, in order to avoid being overwhelmed by data and the inability to make decisions.
How to measure a sales lift caused by the screen without fooling yourself
It is important to run a before-and-after experiment with a control group when possible. You need to compare similar periods in terms of day of the week and hour of day, and ensure the same promotions, discounts and inventory were in place. A/B tests can be conducted, for example branches with screens versus branches without, or different content variants.
Be careful of seasonal biases, special sales events or other marketing campaigns running in parallel that are unrelated to the screen. Accurate attribution requires isolating variables and using control techniques and comparison groups. A study published in Journal of Retailing emphasizes that a sales lift is not guaranteed and that the distance between the screen and the product has a significant impact.
Recommended measurement method – phased experiment and pilot:
It is recommended to start with a small pilot and install screens in a limited number of branches or areas. Measure the results against similar branches without screens, which serve as a control group. Only after proven success should you scale the rollout gradually. This method reduces risks and allows you to learn and optimize before broad deployment.
How to calculate savings on printing and updates as part of ROI
To calculate print savings, quantify the monthly or annual cost of printing materials such as ads, menus, promotions and temporary signs. Also include the costs of distribution, physical installation and the labor time dedicated to replacing printed signs.
Compare this amount to the operational cost of creating digital content and updating it through the system. In places with frequent updates, such as restaurants with changing menus or stores with flash promotions, this saving can be very significant and become a major ROI driver.
What are the common mistakes that reduce ROI in digital signage
The most critical mistakes include investing in hardware without a content plan, meaning buying expensive screens while neglecting original, relevant and refreshed content. Displaying irrelevant messages that are not tailored to the target audience, the time of day, the screen location or the goal is another common mistake.
Poor or congested placement, meaning screens that are not placed in areas with sufficient traffic or in strategic locations, significantly hurts ROI. Lack of measurement and learning loops, meaning setting up signage without defining clear key performance indicators (KPIs) and without a measurement and optimization process, is a common failure. Content that is not updated quickly becomes background noise that customers ignore.
Content fatigue – how to identify and how to fix it
Signs of content fatigue include a drop in engagement rates or QR scans, indifferent or negative reactions, repetition of the same content, and customers physically ignoring the screens.
Remedies include maintaining a consistent content refresh frequency, creating content relevant to the time of day, day of the week or season, developing content templates that make updates easy and fast, and continually monitoring KPIs and replacing content that is not delivering results.
What should be included in a content plan to increase return on investment
An effective content plan includes clear goals for each screen or area: what is the main purpose of the displayed content – is it increasing sales, shortening queues, providing information or giving directions. Messages must be tailored to the customer journey touchpoint, meaning content that is relevant to the specific customer at the specific point.
A consistent schedule should be set for updates and rotation with a clear plan for content refresh frequency. A clear call to action is essential: what do we want viewers to do after seeing the message. Finally, clear operational accountability: who is responsible for creating content, who for updates and who for monitoring performance. The screen is just a platform; the real value is created by the right message delivered at the right time and place.
How often should content be updated to maintain ROI
The more commercial or promotional the message, the more frequent the refresh needs to be. Flash promotion messages can change every few hours, event notices change daily, and a menu can be updated weekly. More general informational content such as opening hours or the venue’s history can be more static.
It is recommended to create predefined content templates that allow you to update information quickly and efficiently, without the need to create a new content item from scratch each time. For example, a discount promotion template or a product of the week template. This saves content creation costs and increases signage viability.
Numerical example – step-by-step calculation of return on investment in digital signage
A complete and clear numerical example is the best way to illustrate ROI calculation. We will start by defining CAPEX setup costs: screen cost ILS 3,000, player cost ILS 500, installation cost ILS 1,500. Total CAPEX: ILS 5,000.
Monthly OPEX ongoing costs: software license ILS 150, content creation ILS 300. Total monthly OPEX: ILS 450. Monthly benefits: print savings ILS 400, estimated additional revenue ILS 600. Total monthly benefit: ILS 1,000. Net monthly benefit: 1,000 – 450 = ILS 550. Payback period: 5,000 / 550 = approximately 9 months.
| Component | Amount | Frequency |
|---|---|---|
| Screen cost | ILS 3,000 | One-time |
| Player cost | ILS 500 | One-time |
| Installation cost | ILS 1,500 | One-time |
| Software license | ILS 150 | Monthly |
| Content creation | ILS 300 | Monthly |
| Print savings | ILS 400 | Monthly |
| Additional revenue | ILS 600 | Monthly |
| Net monthly benefit | ILS 550 | Monthly |
| Payback period | Approx. 9 months | – |
How to prove ROI to management or the business owner in simple words
Building a convincing argument requires three simple slides. First, present the total cost (TCO) of the digital signage alongside the measurable benefit including savings and revenue. Second, present the ROI and payback period under the most conservative scenario and emphasize that the investment is justified even in the less optimistic case.
Third, explain what the business could lose if it does not adopt digital signage, for example wasting money on printing, missing sales and a poorer customer experience. The ability to connect the platform to external information systems such as CRM or POS enables reliable measurement of the impact on sales and significantly strengthens the argument. The cost-benefit analysis page of the Digital Clusters provides an economic framework for justifying budget.
How to start correctly to maximize ROI from the very first month
A phased and focused starting strategy is the key. Begin with a small pilot, a limited rollout in selected locations with a success check. Choose high-impact locations: screens at critical decision points such as the entrance, checkout or a central waiting area.
Make sure every content item has a clear goal and a KPI that measures its success. Monitor the data, make adjustments to content and placements, and expand the rollout gradually and only on the basis of proven success. Only a well-planned start, with clearly defined goals, consistent measurement and ongoing screen content optimization, will ensure maximum return on investment in digital signage.
Frequently asked questions
Using the formula: (total benefit – total cost) / total cost x 100. You must include all costs including setup and operations and all benefits including savings and revenue over a defined period.
Both are important. ROI shows the long-term efficiency of the investment, while payback period shows how long it takes to cover the initial investment. Entrepreneurs usually start by examining the payback period.
Monthly operating costs include software licensing, electricity, content creation and updates, and sometimes maintenance costs. The amount varies greatly depending on the scope of the system, content complexity and the service provider.
Commonly forgotten costs include employee time for content updates, connectivity and network costs, ongoing electricity costs, and wear and maintenance over time. Failing to address these costs leads to a misleading ROI calculation.
ROI is measured through indirect benefits that translate into monetary value, such as saving time for customers and employees, reducing congestion, decreasing errors, or improving customer satisfaction metrics that prevent churn and boost reputation.
Usually because of the lack of an organized content plan, displaying irrelevant messages, non-strategic screen placement, and the absence of measurement and monitoring of results.
Yes, absolutely, if the screens replace existing costs such as frequent printing, streamline processes or drive a measurable increase in revenue, and not just enhance appearance.
