Amount in US dollars.
Both plans keep the same total monthly payment, including freed minimums. Monthly interest is APR / 12, rounded to cents before payment. Minimums are paid first; remaining money follows the initial priority order. No fees, new borrowing or rate changes. Your statement may use daily interest.
Your result
