Advice request on additional loan payments and early settlement interest charge

SussexTech

Hi. Seeking advice from the hive here.
So - have a personal loan. Early settlement incurs 58 days interest charge (it has several years to run). Additional payment has been made whilst monthly payment has remained same. So more of monthly payment capital is paying down capital amount and less interest payed.
Question is - if I settle the loan now, what interest amount applies to the 58 day rule.
eg The interest that would be charged had the additional payment not been made ? The interest amount of the last monthly payment? Or what would be the interest amount paid next monthly payment ? Or something else ? Thanks for reading.

TLDR: Does making additional payment(s) prior to early loan settlement reduce the 58 day interest "penalty" amount ?

None of those

It's 58 days of interest based on the APR of the loan, calculated on the outstanding balance.
