Re: Value of quoted APR
fair enough crugers; moving on from the argument about whether the formula CANNOT be used (it can) and i accept that it WILL NOT be used, then what do you think about the whether it SHOULD be used?
there's nothing creative about my use of he formula really. the beauty of the formula is that it doesn't care what terms you use to describe the flows of money to and from the institution. money is money; if, under the lending agreement with the institution, i'm obliged to transfer money to them, it goes into the right hand side of the formula and if the institution is obliged to transfer money to me it goes into the left hand side.
for example, consider this agreement with your credit union: a 4000 loan for a year at 10% with quarterly payments backed up by 1000 in mandatory savings at 3%. let's look at what happens in such a situation:
1) cu gives you 4000, you give them 1000; this is COMPLETELY equivalent to the cu giving you 3000.
2) after 3 months you pay 1061
3) after 6 months you pay 1061
4) after 9 months you pay 1061
5) after 12 months you pay 1061 (clearing your loan) and collect 1030 savings; this is COMPLETELY equivalent to you paying the credit union 31 euro.
the bottom line is that your agreement with the credit union is COMPLETELY equivalent to borrowing 3000 and paying it off with a series of payments of 1061, 1061, 1061 and 31 every three months.
unfortunately if you went to a bank and asked to arrange a loan on that basis they'd be obliged by the act to tell you that you were being charged 14.7% apr while the credit union will be able to tell you that you're borrowing at 10% even though the arrangements would be COMPLETELY EQUIVALENT. i think this is bad for consumers by making it difficult for them to compare the cost of credit and it's somewhat disingenuous on the part of the credit union movement.
take another example, you need 3000 and get it by borrowing 4000 at 12% from the credit union while leaving 1000 in savings earning 3%. unless this was to be paid off within 4 months, you'd actually save yourself money by putting the 3000 on your credit card as the real apr is over 19%.
