A quadratic equation is the equation having the form ax2 + bx + c=0. In this equation, x is an unknown, a, b and c are known numbers. They are called coefficients of the equation. In this equation, a is the quadratic coefficient, b is the linear coefficient and c is the constant or free term. When the value of ‘a’ is 0, the equation becomes a linear equation.
A quadratic equation calculator takes an input of A, B, and C to give the values of x1 and x2.
Investment calculators give us the initial idea about the amount obtained after a period of investment. The necessary input factors are the value of the initial investment, the period (in weeks or months or years) and the interest rate. The output is given as a total value of the investment and the interest amount based on the rate. Based on the years given, the interest rate for every year is given with the corresponding amount.
Mortgages are loans obtained in lieu of a property that is pledged for a particular sum of money, with a promise to pay back the borrowed amount along with the interest in installments. The mortgages are differentiated based on the interest rate calculated. The two types are fixed rate mortgage calculator and adjustable rate mortgage calculator
In this method, the rate of interest is fixed at a particular percentage and it remains as a constant till the end of the mortgage period. This means that the calculation of the interest and correspondingly the total amount based on the principal is easier to calculate. In this method, the payments are fixed, and the monthly payments do not change until the mortgage period is over.
In adjustable rate mortgages, the rate of interest is not constant. It keeps varying as per the convenience of the lender and the borrower. The terms are agreed upon previously when the loan period begins. In this adjustable rate mortgage calculator, the payments will vary in amount because the interest rate varies. Most probably, the interest rates will increase with time so the loan period could be shortened.
Adjustable rate mortgages need not always have varying rates of the interest. They can even begin with a fixed rate of interest and continue with that rate of interest for a particular time period until after which the mortgage rate changes. This is given as (for example) 5 year ARM, 7 years ARM etc., based on the number of years for which the initial rate of interest remains the same.
The FRM Calculator and ARM Calculator available online can accurately calculate the interest amount, the appreciation of the principal and the monthly payments required over the time period. This makes the job much easier, especially in the cases of adjustable rate mortgage calculator because the varying rates of interest and changing amount of payment might otherwise be very confusing.
