For philippines bank settings:
Savings n checking int. rates are computed d same as wid any other banks
-average daily balance x int. rate x no. Of days/360 - tax
For auto n housing loan
-dont know d formula but not based on perpetuity.. Youll notice monthly amortizations for these personal loans are the same thru-out the entire term of the loan... So basically, there are months wherein if interest is high, then principal is low and vice versa...
Or business loans
-amount of promissory note x rate x no. Of days/ 360.. However, take note if collected in arrears or advance.. If in arrears then the rate theyre chargin is the real rate... If in advance, basically it costs more than the said rate...
Financing companies charge add-on rates... Not all thou...
Interest rate computations vary from 1 product to another, even in 1 company..
