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.
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 %!
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.

A fixed percent of the principal of a loan or investment is called a fixed interest. It is paid monthly or annually or whatever based on the agreement made.
An amortized loan is just a basic loan where the principal and interest are paid on a monthly basis. Usually, the majority of the interest is paid first, then the principal.
An interest-only loan requires only interest payments for a certain period, with the principal paid later. An amortized loan requires both interest and principal payments throughout the loan term, gradually reducing the balance.
The total interest paid on the principal amount borrowed is the additional money paid on top of the original loan amount as compensation to the lender for borrowing the money.
