A = P*(1+R/100)T
Where A = amount
P = Principal
R = Interest Rate (in percentage), and
T = Time
Since R and T are known, you can calculate (1+R/100)T = k, say.
Then A = P*k so that P = A/k

How do you calculate principal and interest when amountrate of interest and time period is given?
The amount, P, is the principal. If the rate is r% compounded annually for y years, then the total interest earned is P*[(1 + r/100)^y - 1]
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 %!
Is simple interest at 4.25 percent better than compound interest at 4.25 percent?
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.

How do you calculate investment amount that compounds quarterly?
The quarterly compound interest of a principle can be given by A=P(1+(r/n))^.25t. Here P is the principle, A is the amount and t is the time taken.

What is the definition of present value?
The principal which, drawing interest at a given rate, will amount to the given sum at the date on which this is to be paid; thus, interest being at 6%, the present value of $106 due one year hence is $100.
What is the average mortgage payment on 130000?
I don't think there is a such a thing as an average mortgage payment on any given dollar amount. The principal and interest payment depends on several factors besides the loan amount, primarily the interest rate and loan term(length of the loan). To keep it simple, a 130,000 mortgage at 4.5% for 30 years would be $658.69 for your principal and interest payment. If you could afford to do a 15 year loan, at the same interest rate, the monthly payment would be $994.49 and you would save nearly $60,000 in interest. If you change the interest rate, the payment could change significantly also.

If you have a semiannual 2year loan with an interest rate of 3 percent If your principal is 1200 what is the compound interest at the end of the 2 years?
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 1.032)The final amount can be worked out like this:1200 x 1.034 = 1350.610572 = 1350.61 (2 d.p.)3)Therefore the interest is1350.61 - 1200 = 150.61
