Thanks @vanitas..agree with u

Point#2, yes..The ptptn monthly installment is RM179.
After further details calculation :
For 28k loan, The total PTPTN interest is 23.33 (ujrah) + 1.27 (insurance) = RM24.70 per month.
-net interest, For 15yrs = RM4,446
- Loss of 20% discount = 28k*20% = RM5,600
- Total = RM10,046
Invest RM22.4k in PTPTN @6%, 15yrs, as per your point#1 RM53,600, return RM31,200.
If i go for lower return @4%, 15yrs compunding, is RM40,300, about RM14k return.
Finally, we decided to go for Option 2, for my niece. She have some saving from intern allowance and started to work 6 months ago. Thought we join hand and kill the loan before 31dis, but now change the plan to Option 2.
Thanks again @vanitas to give some lead

I see, ptptn got some hidden fee in addition to 1% interest. The loss of 5600 is 15 years years earlier, but return @ 6% or 4% is 15 years later, cannot compare like that.
Anyway, for clearer comparison, assume your niece is borrowing only 22.4k at the first place. No discount, like buying house.
Option 1 is paid full.
Option 2, from 22.4k to (28k + 4446) over 15 years, is equal to loan rate at 5.15% (monthly repayment 178.89).
* Saving guide for option 2, I read certain credit cards with online transaction rebate works on ptptn, like pbb visa signature (6%), quantum master (5%). I couldn't verify this, if interested go check out for her.
As long as can generate more than 5.15%, then it is good deal. ASNB is 6% now, with some risk taken when bursa crashed, it is easy. But again, if your niece is not financial savvy, then better paid off the loan.
