Hello Sherwin,
I assume your question applies to the Capital HarnessXC domain; in this case, while we are not providing out-of-the-box calculations, they may be modeled using a Processing plugin (see "Harness Processing Extensibility" in InfoHub), according to the customer’s rules. Indeed, the harness definition data is available and can be queried in the API; one would need to understand what the expected output is, so as to understand where to store the resultant data: is it a report in which to display the results? Also we would need to understand the calculations formula used?
I am attaching a couple of slides on this taken from the Capital 2014.1 What's New deck.
