Difference between Interest Rate vs Annual Percentage Rate
The percentage of principal charged by a lender for the use of its capital is commonly referred to as interest rates. When it comes to lending money anyone can give money and charge interest like banks, nonbanking financial companies or sometimes even individuals. The amount of money lent is known as the principal, and banks pay you the interest rate on deposits which they are borrowing from you.
For example, let’s say that a bank has accepted a deposit from a depositor at a 6% interest rate, now in order to make profits banks will charge the borrowers of money a higher interest rate, maybe 8%, with which the bank is expected to make a profit or spread of 2%. Due to the increasing competition to get more depositors and borrowers, all the banks keep their interest rates in a narrow range to each other.
Banks levy interest rates to the total unpaid amount of the loan or your credit card balance. It becomes important to be aware of the prevailing interest rates on your money and it is the only way to know your outstanding debt. At least the interesting part should be paid out of the loan outstanding else the debt will increase even after you make payments.
Annual percentage rate includes any fees a bank may charge and allows you to compare the cost of different borrowing options. Because the bank calculates them as a percentage point of the total, these onetime fees are called points.

However, if the tenure of the stay is not long, it does not make sense to pay upfront fees and instead one should get a higher APR as the total costs will be less over the first years.
