Name

Gain Rate

Synopsis

Purpose
Determine the average amount of time it takes to accumulate each Gain.
Formula
Gain Rate = (Time Elapsed / Gain)

Example

A new software release is issued at the end of June. The following new user activations (Wins) are recorded for the three months following release:

Month of July: 225 new user activations
Month of August: 270 new user activations
Month of September: 350 new user activations

The following trial data is recorded for the three months following the product release:

Month of July: 81 Trials Complete, 67 Successful Trials
Month of August: 107 Trials Complete, 88 Successful Trials
Month of September: 142 Trials Complete, 119 Successful Trials

The Total number of Unsuccessful Trials during this period can then be calculated as follows:

Unsuccessful Trials in July = 81 – 67 = 14
Unsuccessful Trials in August = 107 – 88 = 29
Unsuccessful Trials in September = 142 – 119 = 23

The following user deactivations or cancellations (Losses) are recorded for the three months following release:

Month of July: 18 deactivations or cancellations
Month of August: 13 deactivations or cancellations
Month of September: 24 deactivations or cancellations

Using the above data, the Gain per month can be calculated as:

Gain for July = 225 - (14 + 18) = 193
Gain for August = 270 / (29 + 13) = 228
Gain for September = 350 / (23 + 24) = 303

From which the following are the Gain Rate calculations per month and the Average:

Gain Rate in July (month with 31 days) = (31 × 24) / 193 = 3 hours 51 ...
