The cost of borrowing, which compensates lenders for the RISK they take in making their money available to borrowers.
Without interest there would be little lending and thus a lot less economic activity.
Some American states also have usury laws, imposing tough conditions on the terms set by lenders, although not actually prohibiting interest. Yet, as the recent rise of a substantial banking industry in Islamic Middle Eastern countries shows, when economic growth is a priority, ways can usually be found to pay lenders to lend.
Compounding Interest versus Simple Interest
Compounding interest is "interest on interest."
It is a method of calculating interest where the interest is added to the original principle.
This new value is now our principle for the next time period. In this method the interest earned in past terms can earn interest in future terms.
Simple interest is a type of interest that is paid only on the original amount deposited and not on past interest paid.

is usually expressed at an annual rate: the amount of interest that would be paid during a year divided by the amount of money loaned.
Developed economies offer many different interest rates, reflecting the length of the loan and the riskiness and wealth of the borrower.
People often use the term “interest rate” when they mean the short-term interest rate charged to banks. For instance, when a central bank raises or cuts interest rates, it changes only the price it charges to banks borrowing money overnight, expressed as an annual rate.
Bond yields are a better measure of the interest rate on loans that do not have to be repaid for many years.
Unlike short-term interest rates, bond yields are determined not by central bankers but by the supply and demand for money, which is heavily influenced by the expected rate of inflation.
This holds true because of
. When interest rates are low, borrowers are at an advantage and there is a higher flow of hard cash; when interest rates go up, it becomes more advantageous to hold money in the form of bonds to get a greater return, and thus
liquidity goes down

Rise and Decline in Interest Rates
The specific effects of inflation and deflation are mixed and fluctuate over time.

. Lower prices may eventually encourage improvements in consumption, investment, and foreign trade, but only if the fundamental causes of the original deterioration are corrected.
Inflation initially increases business profits, as wages and other costs lag behind price increases, leading to more capital investment and payments of dividends and interest.
Personal spending may increase because of “buy now, it will cost more later” attitudes; potential real estate price appreciation may attract buyers.
Domestic inflation may temporarily improve the balance of trade if the same volume of exports can be sold at higher prices. Government spending rises because many programs are explicitly, or informally, indexed to inflation rates to preserve the real value of government services and transfers of income. Officials may also anticipate paying larger budgets with tax revenues from inflated incomes.
