ARPU: Average Revenue Per User

Imagine a canteen with a million members paying a monthly fee, where the owner cares less about the total member count and far more about how much, on average, each member actually spends every month, since that single number decides whether raising more members further even makes financial sense. ARPU is exactly this figure for a telecom operator.

Average Revenue Per User is calculated by dividing an operator's total revenue over a period by its average number of subscribers, giving a clean, standard measure of how much value each customer generates monthly. Because Indian telecom historically competed almost entirely on rock-bottom pricing, ARPU spent years compressed near the lowest levels of any major telecom market in the world.

That has changed meaningfully in recent years, driven by successive, coordinated tariff hikes across operators, Airtel's ARPU rose from roughly Rs 166 in FY22 toward Rs 275 by FY26, with an explicit company target of Rs 350 by FY28, while Jio's ARPU rose from Rs 195.1 to Rs 211.4 between September 2024 and September 2025 alone.

ARPU matters enormously more than subscriber count alone because Indian telecom's economics only genuinely work at higher revenue per user, network infrastructure, especially 5G, is expensive to build and maintain regardless of how cheaply an operator prices its plans, so an operator adding subscribers at ARPU too low to cover its own network costs is growing its customer base while destroying its own returns.

Whenever a telecom operator announces a tariff hike, ARPU growth, not subscriber growth, is almost always the underlying justification, a deliberate strategic shift toward extracting more value per existing customer rather than simply chasing ever more subscribers at unsustainably thin margins.
