Calculated metrics overview

Calculated and Advanced Calculated (or Derived) Metrics are custom metrics that you can create from existing metrics. Our Calculated Metrics tools offer a highly flexible way of building, managing and curating metrics. They allow you as marketers, product managers and analysts to ask questions of the data without having to change your implementation.

You can

Create filtered metrics that are derived at report run time, without having to change the implementation. These can be viewed historically because they are based on filters.
(Advanced Calculated Metrics only) Filter on metrics. For example, you can create a metric for “New visitors”, with a count of people for whom this is the first session.
(Advanced Calculated Metrics only) Incorporate statistical functions to help you better describe your data. For example, you can count the number of items in a report or add in the number of standard deviations for each item.

Calculated metrics versus advanced calculated metrics

Here is a comparison of Calculated Metrics and Advanced Calculated Metrics capabilities:

Builder Options	Calculated Metrics	Advanced Calculated (Derived) Metrics
Format types (decimal, time, percent, currency	Yes	Yes
Attribution changes (default, linear, participation, etc.	Yes	Yes
Metric types (standard, total	Yes	Yes
Basic operators (add, subtract, multiply, divide)	Yes	Yes
Apply filters	No	Yes
Basic functions (count, abs value, mean, etc)	No	Yes
Advanced functions (regression, if/then, t-score, etc)	No	Yes

Tools

Tool	Capabilities
Calculated Metric Builder	Create calculated and advanced calculated metrics using advanced allocation models. Add filters inline to metric formulas. Compare filters in the same report. For example, compare local visitors vs. international visitors. Use statistical functions. Provide detailed metric descriptions (show what it does, where to use it, where NOT to use it). Copy definitions into new metrics. Provide an inline metric preview. Set metric polarity, which indicates whether it’s good or bad if a given custom event (metric) goes up. Tag metrics.
Calculated Metric Manager	Share metrics with others. Approve and curate metrics. Organize (tag) your metrics so people can find them. Delete metrics. Rename metrics.
API for Calculated Metrics	Part of the CJA API set.
