, etc., per unit time, typically per year or month. In mobile telephony, ARPU includes not only the revenues billed to the customer each month for usage, but also the revenue generated from incoming calls, payable within the regulatory interconnection regime.

This provides the company a granular view at a per user or unit basis and allows it to track revenue sources and growth.

There is a trend by telecommunications and Internet companies and their suppliers to sell extra services to users and a lot of the promotion that is used by these companies talks of increased ARPU for these operators. It typically manifests in the form of value-added services such as entertainment being sold to customers especially in markets where the primary service offered to the customer, such as the telephony or Internet service, is sold at a commodity rate.

Method of Calculation:
To calculate the ARPU, a standard time period must be defined. Most telecommunications carriers operate by the month. The total revenue generated by all units (paying subscribers or communications devices) during that period is determined. Then that figure is divided by the number of units. Because the number of units can vary from day to day, the average number of units must be calculated or estimated for a given month to obtain the most accurate possible ARPU figure for that month.
Also related is ARPPU (Average Revenue Per Paying User) which is calculated by dividing up the revenue amongst the users who paid anything at all. This yields a figure that is significantly larger than ARPU. For example in the case of a subscription game (that has a free play version), the ARPPU, measured by accounts, is the subscription price, diluted slightly by free trials.

A related (but less used) measure is AMPU, or average margin per user
Average margin per user
Average margin per user is one of several criteria for measuring the success of telephone companies. It is an alternative to ARPU, which focuses on revenue per unit. The central premise is that by attention to the margin produced per sold unit, not the amount of cash earned from each customer,...

ARPU is widely used by Internet Protocol television (IPTV) service providers.
