The One Model calculation engine makes it easy to allocate costs across periods of time. All you need to do is create a data set that shows the amount of cost to allocate, along with the start and end dates of that allocation.
For example, if you spent $10,000 on job advertisements on LinkedIn from January 1, 2018 to December 31, 2018, One Model can easily allocate that spend on a per day basis across the year.
This becomes very useful when combined with other metrics over periods of time. For example, I can compare what I'm spending on LinkedIn with the number of applications I receive from LinkedIn during that period of time. This yields a Cost Per Application metric that I can use to compare the effectiveness of LinkedIn relative to other sources.
In the following video I cover this functionality in detail, using source spend as an example. However, the same logic can be used to allocate other costs as well, like employee salaries.
