Hi I have a HDB loan of $50,900 at 2.6% p.a. with a 12year repayment period.
My monthly instalment is $413 which means I am paying in total $59472.
Could anyone help me figure how does the math of 2.6% make $50900 into $59472 ?
Interests are calculated based on how much loan balance there is at the end of each month.
Go to any website that has a mortgage calculator and you will be able to see the monthly installments and often the amortization schedule. For 50,900 at 2.6% over 12 years, technically you should be paying 411.86 per month. Usually it's rounded up to $412, so not sure how come yours is $413.
Nevertheless, what will happen is your final payment will be less than $413. In this case, based on my calculation, your final payment would be $219.97. Effectively you'd have paid $8,378.97 in interests, or $59,278.97 in total.
