Preview Roll Payment

This request allows you to preview the effects of a Roll Payment configuration for a loan.


LoanPro's loan calculator offers a Roll Payment feature so you can test some basic loan terms. Here's what you need to know about this request:

  • The roll payment feature will help solve payment equations by allowing you to choose a variable to solve for.
  • You determine your solve parameters in the endpoint of this request.
  • Your loan will need to have its setup terms completed before the roll schedule feature will work.
  • This request does not save a roll payment configuration on the loan but instead simply provides a preview.

For an example of how this feature works in the UI, take a look at our Roll Payment article.

How to Interpret Your Response

The response for this request may look a bit confusing if you don't know what you're looking at. Here's an example of what the response will look like:

  "d": {  
    "method": "loan.rollPayment.term",  
    "payment": 190,  
    "solution": 58  

The method field determines what value you are trying to solve for. In this instance, the calculator is solving for loan term, or the amount of payments it will take for the loan to be paid off. The ideal payment amount in this example is set at 190. Using the other terms of the loan, the calculator determines that it will take 58 months with payments of $190 to pay off the loan.
