Here, Are The Different Compound Interest Formulas Used In Solving Compound Interest Problems: Here, is the compound interest formula that is derived to make it possible for other elements in compound interest problems to be solved. It is made to solve for the outcome of a compound interest investment or a compound interest loan with the compound interest concept. FV = PV(1 + i)n Wherein: FV: is the future value is the amount being solved for. It is the outcome of an investment or loan. PV: is the present value. It is also known as the current cash amount of an inves tment. i: is the rate of interest. It is usually given in its years form. n: is the periods of compounding interest in a year. Here, is the formula used for solving the present value or the principal amount in a compound interest problems in investment or debt. PV = FV ÷(1 + i)n Here, is the formula used for solving the rate of interest in years form in compound interest problems. i = (FV / PV)1/n-1 Here, is the formula used for solving the number of time the interest gets compounded. n = log(FV) – log(PV) ÷ log(1 – i) Here, is the standard compound interest formula used in solving for the final amount of compound interest problems. A = P(1 + r/n)nt Wherein: A: is the total outcome of either a loan or an investment with the compound interest concept. P: is the principal amount. It is also known as the principal amount or first amount deposited in an investment. For loans, it is known as the first installment amount which is usually the biggest amount. r: is the rate of interest in a yearly manner. It is usually in decimal form when you use it with the formula. However in examinations, it is usually given in its percentage form. n: is the times the interest gets compounded. There are different periods. Such periods are the following: yearly which is equal to one, bi-annual which is equal to two, quarterly which is equal to 4, and so on and so forth. t is the time periods of the whole loan or investment or the time period to be so lved that is given in compound interest problems. Here, is the formula used in solving for the periodic compound interest problems. A(t) = A0(1 + r/n)nt Wherein: A(t): is the Amount function A0: is the Coefficient More of compound interest problems and compound interest formula, visit William Ava’s Blog Site click here.
