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 ... |
