Find Variable Interest Rates


  1. A Highnote account
  2. A credit card product with the variable interest feature enabled
  3. Access to the GraphQL API, API Explorer, or Dashboard


Highnote supports variable interest rates for credit card products. Highnote provides updated prime rates as necessary, and it is your responsibility to reflect accurate interest rates to your account holders. Highnote calculates APR by using the sum of the prime rate and the margin you provide. The prime rate used when calculating your APR reflects the Wall Street Journal's Prime Rate, published on December 25th, March 25th, June 25th, and September 25th. Updated rates take effect at the beginning of the next billing period: January, April, July, and October, respectively.
