Question

What is interest rate? How is interest rate decided?

Answer 1

A rate which is charged or paid for the use of money. An interest rate is often expressed as an annual percentage of the principal. It is calculated by dividing the amount of interest by the amount of principal. Interest rates often change as a result of inflation and Federal Reserve Board policies. For example, if a lender (such as a bank) charges a customer $90 in a year on a loan of $1000, then the interest rate would be 90/1000 *100% = 9%.

Answer 2

Answer:

The interest rate charged by banks is determined by a number of factors, such as the state of the economy. A country's central bank sets the interest rate, which each bank use to determine the APR range they offer. When the central bank sets interest rates at a high level, the cost of debt rises.
