ahh so ganyan pala ang pagcompute ng interest, kapag nakuha na ung interest na binayaran mo over the 5years, dpat pala idivide sa loaned amount, not the SRP hehe.. kasi ang computation na ginawa ko po ay ganito:
SRP: 699000
DP: 98650
Monthly: 11735
[(11735 monthly * 60months) + DP 98650] - SRP 699000 = 103750 pesos sa interest, then
(103750 / 60 months) * 12 months to get the year then divided by SRP bale [(103750 / 60) * 12] /
SRP 699000 = 20750 / 699000 = 0.029 which is 2.9% per year then * 5 years = 14.84% hehe..
nagkamali po ako dun sa second part, dapat pala is ung interest na 103750 is ididivide sa loaned amount na 600350 to get the 5years

now I know na that's how to compute the interest with the given figures hehe
salamat sir chief
