I recently got a loan "100k a day". The loan goes for 50 days and heres my problem.

If it's 100k a day and I pay 500k before the update shouldn't 4 days be removed?
500k -100k for that days payment ;400k for the next 4 days.

Istead right after the update it shows I need to pay X amount for the following day.

Why?

You have reduced the total amount you have to pay but the term stays the same : you'll just repay less each day.

Each day that passes, the system recalculates remaining installments for the remaining period of time. Time remains the same, installments change accordingly.

Thanks
