Does an increase of 4 percent in the interest rate result in a 4 percent increase in the total interest paid?
Not usually. A "4 percent increase in the interest rate" usually means that there is some reference interest rate of x percent that is increased to 4 + x percent. This means that the interest paid increases from x percent of the principal to 4 + x percent of the principal. Therefore, the interest paid increases by 100 (4/x) %. For example, if a recent Federal funds rate of 1 % in the United States were to be increased by 4 %, the interest paid on any given amount of principal would increase by 400 %!
If a simple interest of 4.5 percent was paid at the end of the year then find the balance at the end of the year?
The formula for simple interest is Interest = Principal x Rate x Time ÷ 100 As the rate is an annual rate and the period is 1 year then Interest = Principal x 4.5/100. The balance at the year end = Principal + Interest = Principal x 104.5/100.
