Digital Signage ROI — How to Measure and Justify the Investment

Making the Business Case for Digital Signage

Every digital signage investment needs a business case. Whether you’re a single-site retailer justifying the cost to yourself, or a head of marketing seeking board approval for a 50-site rollout, the question is the same: what will this return?

This guide provides a framework for calculating digital signage ROI, with realistic benchmarks drawn from industry research and Alliance customer data.

The Four Return Drivers

Digital signage generates return through four mechanisms:

1. Increased Revenue

Uplift in average transaction value: When customers see promotions, they buy more per visit. Research from the Outdoor Advertising Association and Nielsen consistently shows that digital in-store media drives impulse purchase. Benchmarks vary by sector:

• Quick service restaurants: 3–8% uplift in average transaction value from digital menu boards
• Retail: 5–15% uplift in promoted product sales when featured on screen
• Hospitality: 10–20% increase in upsell conversion (room upgrades, F&B packages)

Example calculation (retail):

• 300 transactions per day, £25 average basket
• 5% uplift from digital screens = £1.25 per transaction
• Annual uplift: £1.25 × 300 × 365 = £136,875 additional revenue per year

2. Reduced Costs

Elimination of print costs: Printed signage, menus, posters, and promotional materials represent significant ongoing expenditure. Typical print costs for a retail or hospitality business:

• Seasonal campaign materials: £2,000–£5,000 per season
• Menu reprints (3–4 per year for a restaurant): £500–£2,000 per reprint
• In-store promotional materials: £3,000–£10,000 per year
• Staff time managing printed materials: 2–4 hours per week

Annual print and production savings (typical): £5,000–£20,000 for a single site.

Reduced staffing costs: Screens that answer common customer questions (menu, prices, services, directions) reduce the volume of staff interventions. A screen in the waiting area that explains the service process reduces intake appointment length by an average of 8–12 minutes (from Alliance customer data).

3. Improved Customer Experience

Customer experience improvements are harder to measure directly but are linked to revenue through NPS, repeat visit rate, and dwell time:

• Reduced perceived wait time: Engaged customers perceive wait times as shorter. A patient who watches health information while waiting reports a significantly shorter perceived wait than one who stares at a wall.
• Increased confidence in purchase decisions: Customers who have been educated about products are more confident and have fewer returns.
• Reduced complaint rate: Clear communication of policies, processes, and expectations reduces frustration and complaint volume.

4. Operational Efficiency

• Faster menu and price updates: A multi-site business that can update all screen menus in 30 seconds vs. 2 weeks of print production and delivery
• Remote content management: No travel to sites to change printed materials
• Emergency communication speed: Critical communications (closures, disruptions, safety alerts) reach all screens in seconds

The Full Cost

A complete ROI calculation requires the full cost picture:

Capital costs:

• Screen hardware: £200–£1,500 per screen (TV for a quick start, commercial display for permanent installation)
• Media player: £80–£350 per screen (or free if using screen’s built-in SoC)
• Installation: £150–£500 per screen depending on mounting complexity

Ongoing costs:

• Alliance software: varies by plan and screen count (see pricing page)
• Electricity: approximately £15–30 per screen per year (based on 12 hours/day at UK commercial rates)
• Maintenance: approximately £50–100 per screen per year

Total cost of ownership (typical single screen, 5-year period):

• Hardware: £500–£1,500
• Installation: £200–£400
• Software (5 years): £600–£1,500
• Electricity + maintenance: £350–£650
• Total: £1,650–£4,050 over 5 years

A Worked Example

Business: A quick service restaurant with 3 screens (menu board, counter upsell, waiting area)

Investment:

• 3 commercial displays: £2,100
• 3 Alliance Players: £450
• Installation: £600
• Alliance software (3 years): £600
• Total investment: £3,750

Returns (Year 1):

• Average transaction value uplift (5% × £8.50 average × 400 transactions/day × 365 days): £6,205
• Print cost savings (menus × 4 reprints, seasonal promotions): £2,800
• Year 1 return: £9,005

ROI Year 1: (£9,005 − £3,750) ÷ £3,750 = 140%

Payback period: Less than 5 months.

Measurement Framework

To measure your actual ROI, track these metrics before and after installation:

Revenue metrics (measure at POS):

• Average transaction value
• Items per transaction
• Promoted item sales volumes
• Conversion rate on advertised services/products

Cost metrics:

• Annual print and production spend
• Staff time on content updates (before and after)
• Complaint and query rate

Experience metrics:

• NPS score
• Wait time satisfaction scores
• Customer survey questions about information clarity

Operational metrics:

• Time to update content (before and after)
• Error rate on pricing/menu changes

Review these metrics quarterly against your pre-installation baseline. The Alliance’s analytics show content performance data; combine it with your POS data for a complete picture.
