Integrating additional calculations into product data
I've been reviewing the Drupal Commerce platform as a possible solution for presenting financial products such as loans to consumers visiting a financial website. I think I can correctly model a loan product, such as a mortgage as product data, but I'm wondering how I might be able to incorporate a calculated monthly payment, based on the loan amount, into the product that gets displayed to the financial consumer.
Are there approaches where I might be able to integrate IDs into the displayed data, such as what I can do with the Drupal Form API suffix and prefix fields? Or are there better approaches I can take to accomplish the same thing.
