How to Calculate Guest WiFi Marketing ROI

Before investing in guest WiFi marketing software, you want to know what return to expect. This guide explains how to calculate the ROI of guest WiFi marketing with a worked example and benchmarks from across the Telexico Connect platform.

The ROI formula

Guest WiFi marketing ROI comes from five revenue streams. Add them together and subtract the cost of the platform:

• SMS campaign revenue — customers who return after receiving promotional SMS
• Birthday club revenue — customers who visit specifically because of a birthday offer
• Win-back revenue — lapsed customers who return after a win-back SMS
• Review value — additional business generated by higher Google review scores
• Data asset value — the growing database of consented contacts (ongoing compounding return)

The benchmark numbers (UK platform data)

Worked example: Restaurant with 600 monthly covers

• Monthly WiFi visitors: 600
• Opt-in rate: 78% = 468 contacts captured
• Average spend: £18
• Return visit rate: 30%
• SMS campaign revenue (30% return × 15% SMS uplift × £18): £378/mo
• Birthday club revenue (8% DOB matches × 5× uplift × £18): £259/mo
• Win-back revenue (30% lapsed × 12% return × £18): £291/mo
• Review value (additional searches from rating improvement): £180/mo estimate
• Total estimated monthly impact: £1,108/month
• Platform cost (Growth plan): £29/month
• ROI: 38:1

The compounding effect

The ROI calculation above is month one. The real power of guest WiFi marketing is the compounding database. Every month, your captured contact list grows. Month 12 has 12× the birthday club potential of month 1. A restaurant capturing 468 contacts per month has nearly 6,000 opted-in contacts after 12 months — a marketing asset worth far more than the sum of its monthly contributions.

What gets captured determines what revenue follows

• No DOB captured → no birthday club → miss the 4–6× uplift window
• No SMS opt-in → no win-back campaign → miss 12% lapsed customer recovery
• No venue-specific questions → generic campaigns → lower redemption

Telexico Connect captures the right fields for each industry automatically — including DOB for the birthday club and vehicle registration for garages.
