How Are Interest Rates Calculated In The UK?

The interest is basically the fee which is charged for the borrowing of money. In other words, the lender of money gets his money back, plus a compensation for the use of his money by the borrower. The initial quantity of money which is lent is referred to as the principal or principal amount, whereas the percentage of the principal amount which has to be paid over a certain time period is termed as the 'interest rate'.
