Running a WiFi captive portal in an African residential estate costs about 45,000 FCFA a month and brings in 60,000 to 80,000 FCFA, leaving a net profit of 15,000 to 35,000 FCFA per site. It takes a base of 40 to 60 active users to hold that range, and the upfront investment pays for itself in three to six months. Because the costs are fixed, you know the break-even point on the day you install.

The 45,000 FCFA monthly cost, line by line

A captive portal in a residential estate runs on three cost lines. The internet subscription accounts for 30,000 FCFA a month, for a professional fibre line of 20 to 50 Mbps or for Starlink where fibre does not reach. Electricity comes to 10,000 FCFA, which matches a continuous draw of 300 to 400 W for the routers and the access points.

The third line is a 5,000 FCFA reserve set aside for maintenance and technical support: replacing an access point, updating the system, paying for a technician to come out. You will not spend it every month, but budgeting for it stops one hardware failure from turning a profitable quarter into a losing one.

Those 45,000 FCFA stay identical month after month, whatever the number of connected users. That is what makes a captive portal readable as an investment: every subscriber past break-even is almost pure profit. How much of the reserve you actually burn depends directly on the hardware you buy, a trade-off covered in the captive portal equipment guide.

Where the 60,000 to 80,000 FCFA in revenue comes from

Revenue from a captive portal in a residential estate comes from a modest base of 40 to 60 active users, spread across three types of customer. Monthly subscribers at 5,000 FCFA form the stable core. Weekly users, at 2,000 FCFA a week, provide the volume. Occasional users buy a day pass whenever they happen to need one.

The 60,000 to 80,000 FCFA range is a conservative one. Well-run sites reach 120,000 FCFA a month, usually through consistent connection quality and regular promotions that turn day-pass buyers into monthly subscribers. Moving customers from daily passes to monthly ones is the biggest revenue lever on a site that is already installed.

Once the 45,000 FCFA of costs are deducted, net profit lands between 15,000 and 35,000 FCFA per site per month, with the investment repaid in three to six months. Those takings stay regular because access is prepaid, a mechanism described in deploying a captive portal with Mobile Money payment.

The pricing grid that works in a residential neighbourhood

In an African residential estate, price drives adoption of a captive portal far more than headline bandwidth does. A four-tier grid covers what the neighbourhood actually does, from the passer-by who needs an hour to the household replacing a fixed line. The reference tiers are these:

  • 200 FCFA per hour, for light browsing
  • 500 FCFA per day, for heavy use
  • 2,000 FCFA per week
  • 5,000 FCFA per month

The gap between tiers has to stay wide enough to push people towards a subscription. At 5,000 FCFA a month, a user pays roughly 167 FCFA a day, against 500 FCFA if they bought thirty day passes instead. That difference is the strongest argument with residents who connect every evening, and it is what keeps the monthly base of a site stable.

The grid only holds if the service keeps up. Below 20 Mbps shared, the very uses that justify a subscription turn painful: online courses, job hunting, selling on social media, training through video. Monthly subscribers then drop back to day passes, and leave the network shortly after.

What one site in Yopougon produced in six months

A captive portal installed in January 2025 in a 200-household estate in Yopougon, Abidjan, had 68 regular active users six months later. The site was bringing in 95,000 FCFA of monthly revenue against 48,000 FCFA of costs — fibre, electricity and maintenance — leaving 47,000 FCFA of net profit a month and full payback in four and a half months.

Three factors explain the gap between that site and the 60,000 FCFA low end. The operator lives in the estate and clears faults the same day. He runs regular promotions that keep users loyal. Connection quality stays consistent, which is enough to convert part of the occasional traffic into monthly subscribers over time.

The Yopougon estate already had partial fibre coverage, and demand came from the households left outside that rollout. A dense, young and underserved area remains the best location for a profitable site, a logic developed further in the analysis of passive income from WiFi.

Going from one site to five, and covering the risks

A captive portal replicates as soon as the first site turns profitable. At 35,000 FCFA of monthly profit per site, three sites return 105,000 FCFA and five sites 175,000 FCFA. Costs scale with the number of sites, but one dashboard is enough to manage the passes sold and the state of the network.

Three risks weigh on a captive portal in a residential estate, and each is covered by a decision taken before installation rather than after the first outage. The 5,000 FCFA monthly reserve exists for exactly that, and it is better left to accumulate in the early months than counted as profit:

  • Unlimited mobile data bundles from the operators, answered with a lower price and hands-on local support
  • Power cuts, which call for a UPS sized for the routers and the access points
  • Hardware failures and internet outages, absorbed by the reserve fund

Unpaid bills, on the other hand, are not a risk in this model: Mobile Money payment is required before the session opens, so a user only reaches the network once the money has cleared. The same economics transfer to a campus, as shown in the student captive portal business.
