Update an Interest Rate Change

This request allows you to update an interest rate change on a loan.


LoanPro's Interest Rate Change tool allows users to change a loan's interest rate at any point in the loan's life. Here's what you need to know about this request:

  • This request will update an existing interest rate change.
  • To update an interest rate change, you will need its ID. To find an interest rate change ID, send a GET request.
  • A scheduled interest rate change will override a schedule roll. For example, if an interest rate change has occurred on a loan and a schedule line later applies, the calculator will use the interest rate specified by the Interest Rate Change tool.
  • Using this tool will affect the loan's APR, and the tool does not have a rate limit. Make sure to comply with your local lending laws when logging rate adjustments.

For an example of how the Interest Rate Change tool works in the UI, take a look at our Interest Rate Changes article.
