1)
In a semiannual loan, the number of times interest will be given in 2 years is 4.
The multiplication factor for 3% interest is 1.03
2)
The final amount can be worked out like this:
1200 x 1.034 = 1350.610572 = 1350.61 (2 d.p.)
3)
Therefore the interest is
1350.61 - 1200 = 150.61
simple interst is when you earn interest from your principal but compound interest is when you earn interest from your principal as well as from your previous interest
P*(1+R/100)powerT where P= money borrowed or principal and R= rate in percent and T= time * * * * * Actually, this formula gives the value of the principal PLUS interest. You need to subtract P from the answer to get the compounded interest.
Simple Interest
Simple interest is the interest you earn on your principal, IE the amount of your original investment. For example, you put 1000 dollars in a saving account paying 3% per annum. At the end of the year you will have earned 30 dollars on that one thousand dollars. If you leave the principal and interest in the account for another year you will earn another 30.00 on your original 1000 dollars plus .90 interest. on the first 30.00 dollars interest. This gives you a total of 1060.90 in your second year. In each succeeding year you will earn interest on your interest plus interest on your original principal which, if left alone will add up to a substantial some given the power of compound interest. One caveat, compound interest is a double edged sword. If you have a loan and fail to make your monthly payments on time, compound interest will gut you financially.
The interest for 1 year is 37.00, whether it is simple or compound interest.
Simple interest means the interest is calculated one time on the total principal of the loan. Therefore, you would pay back $11,161.50 on this loan. However, simple interest loans are very uncommon; most loans in life have compound interest.

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 %!
It is an increasing percentage as the repayment progresses. At the start, it is mostly interest and very little principal whereas near the end it is mostly principal and little interest.

500 principal, 10 percent annual rate => 50 annual interest 2 year => 100 total interest.
