How to Measure Digital Signage ROI: A Step-by-Step Framework for Restaurants

Every restaurant owner considering digital signage asks the same question: "Will this actually pay for itself?" It's the right question. Digital menu boards aren't cheap, and vague promises about "increased engagement" don't help you make a business decision. You need numbers.

This guide provides a concrete, step-by-step framework for measuring the return on investment of digital signage in your restaurant. We'll cover what to measure before installation, what to track after, and how to calculate whether your investment is generating real returns.

Step 1: Establish Your Baseline (Before Installation)

You can't measure improvement if you don't know where you started. Before installing digital menu boards, capture these baseline metrics for at least 30 days:

Revenue Metrics

• Average order value (AOV) — Your most important metric. Pull this from your POS system. Calculate it daily and weekly to account for day-of-week variations.
• Revenue per customer — Total revenue divided by total transactions. Similar to AOV but accounts for different ordering patterns.
• Featured item sales — Track sales of 3-5 specific items you plan to feature on your digital boards. These become your control group.
• Upsell/add-on rate — What percentage of orders include add-ons, sides, or upgrades?

Operational Metrics

• Average order time — How long from a customer approaching the counter to completing their order? Time this for at least 100 orders.
• Menu-related staff questions — Have your staff tally how often customers ask "What do you recommend?" or "What comes with that?" These questions indicate menu confusion that digital boards can reduce.
• Printing costs — Track what you spend on printed menus, specials boards, and promotional materials monthly.

Customer Metrics

• Customer satisfaction scores — If you collect feedback, baseline your scores before the change.
• Repeat visit rate — Track through your loyalty program or POS data.

Document all of this carefully. You'll compare against these exact numbers after installation.

Step 2: Calculate Your Total Investment

Be thorough about capturing every cost associated with your digital signage project:

One-Time Costs

• Display hardware (screens, media players)
• Mounting hardware and installation labor
• Electrical work (if new outlets or cable runs are needed)
• Initial content design and setup
• Network upgrades (if your WiFi can't support the system)

Ongoing Monthly Costs

• Software/platform subscription fees
• Content management and updates
• Electricity (commercial displays typically use $3-8/month per screen)
• Warranty or maintenance fees

For a typical two-screen restaurant installation, total first-year cost ranges from $2,500 to $7,000 depending on hardware quality and service level. Ongoing annual costs are typically $1,200-3,000.

If your installation requires construction work — wall reinforcement, electrical runs, or structural modifications — budget for that separately. SacValley Contractors' commercial renovation cost guide provides realistic pricing for these types of projects in the Sacramento area.

Step 3: Track Post-Installation Metrics

After installation, track the same metrics from Step 1 using the same methodology. Give it at least 30 days — preferably 60-90 — to account for the novelty effect (customers initially paying more attention to new screens) and to gather statistically significant data.

Key Comparisons

• AOV change — Industry data shows digital menu boards increase AOV by 3-8% on average. Even a 3% increase on a $15 average ticket is $0.45 per transaction. At 200 transactions per day, that's $90/day or $2,700/month in additional revenue.
• Featured item sales change — Items given prominent digital placement typically see 15-30% sales increases. Track your control items to quantify this.
• Order time change — Faster ordering means you can serve more customers during peak periods. If order time drops by 15 seconds and you serve 200 customers/day, that's 50 minutes of cumulative time savings.
• Printing cost elimination — This is the easiest win to calculate. If you were spending $400/month on printed menus and specials boards, that's $400/month in direct savings.

Step 4: Calculate Your ROI

The ROI formula is straightforward:

ROI = (Net Profit from Signage - Total Investment) / Total Investment × 100

Let's work through a realistic example for a mid-size restaurant:

Investment

• Year 1 total cost: $5,000 (hardware + installation + first year of service)

Annual Returns

• AOV increase of 4% on $16 average ticket = $0.64/transaction × 180 transactions/day × 360 days = $41,472 additional revenue
• At 25% profit margin on incremental revenue = $10,368 additional profit
• Printing cost savings = $3,600/year
• Labor savings (reduced menu questions, no manual menu changes) = $2,400/year
• Total annual benefit: $16,368

First-Year ROI

($16,368 - $5,000) / $5,000 × 100 = 227% ROI in year one

Year two and beyond, with only ongoing service costs of ~$2,400/year, the ROI climbs even higher. This is why digital signage consistently ranks among the highest-ROI technology investments for restaurants.

Step 5: Optimize Based on Data

Measuring ROI isn't a one-time exercise. The real power of digital signage is the ability to optimize continuously:

• A/B test menu layouts — Try different item positions and measure which generates higher AOV
• Test promotional messaging — "Add a side for $3.99" vs. "Complete your meal with a fresh side salad" — which performs better?
• Optimize daypart content — Track which breakfast items sell better with digital promotion and adjust your morning content accordingly
• Seasonal adjustments — Summer content strategies may differ from winter. Track and compare seasonal performance year over year.

This iterative optimization is what separates restaurants that get modest returns from digital signage from those that get exceptional returns. The screens are a platform — the content strategy determines the results.

Common Measurement Mistakes

Avoid these pitfalls when measuring your digital signage ROI:

1. Too short a measurement period — 30 days minimum. Ideally compare same months year-over-year to control for seasonality.
2. Ignoring external factors — A new competitor opening nearby, price increases, staffing changes, and seasonal traffic patterns all affect your numbers. Try to isolate the signage impact by controlling for these variables.
3. Only measuring revenue — Cost savings (printing, labor, food waste from accurate menus) are equally important to the ROI calculation.
4. Not tracking featured items specifically — Overall AOV is important, but tracking specific featured items gives you actionable data about what content strategies work.
5. Forgetting the opportunity cost — What would that $5,000 have earned if invested elsewhere in your business? Compare your signage ROI to other potential investments.

Tools for Tracking

You don't need expensive analytics software. Most POS systems provide the data you need:

• Square, Toast, Clover — All provide daily AOV, item-level sales data, and transaction counts
• A simple spreadsheet — Track your baseline and post-installation numbers side by side. We can provide a template.
• Your digital signage platform — Most platforms include basic analytics about content display frequency and scheduling

For a broader view of how your restaurant's technology and digital presence are performing, tools like AuditMySite's small business analytics setup guide can help you establish tracking across your website, ordering platforms, and in-store systems.

And as you grow your brand presence, understanding how your restaurant is perceived online helps contextualize your in-store performance. BrandScout's guide to measuring brand awareness covers practical approaches for small businesses.

Getting Started

Start your baseline tracking today — even if you're months away from installing digital signage. The more historical data you have, the more confidently you can measure the impact when you do make the investment.
