Usage Tier Multiplier Overview


You can enable the advanced billing option Usage Tier Multiplier when adding a usage-based service to a plan to accommodate pricing for customers who purchase multiple units of that plan. Usage Tier Multiplier multiplies the units of each unit/rate tier by the number of plan units purchased to calculate rates for the customer’s usage consumption of that service.

The following unit/rate table outlines the effect of the Usage Tier Multiplier when a customer purchases 2 plan units of a plan containing a usage-based service:

Unit Tiers Unit Price Multiplier Tier
(Upper Units of Each Tier X 2)
Unit Price













In the above scenario, the first tier of a rate schedule for a cell phone plan service is $0.03 for 1–200 minutes. A customer who purchases 1 plan unit and consumes 200 minutes of service in a billing period will be charged $0.03 per minute (for a total of $6.00).

With Usage Tier Multiplier enabled, when 2 units of this same plan is purchased, the customer who consumes 400 minutes of this service will still only be charged $0.03 per minute (for a total of $12) because the usage units fall within the first level of the multiplied usage tier.

Reference the Usage Tier Multiplier example for a more detailed use case.

Note: Usage Tier Multiplier can be enabled for all pricing methods (i.e. standard tier, volume discount, and flat rate per tier). Additionally, Usage Tier Multiplier can be applied whether real-time usage rating is enabled or not (i.e. the Automatically Rate Un-rated Usage Records at Load Time system parameter).


You must have at least one usage-based service configured in your Aria instance.
