The formulas for obtaining the future value (FV) and present value (PV) are: FV=PV×[1+in](n×t)PV=FV÷[1+in](n×t)where:i=Interest rate in percentage termsn=Number of compounding periods per yeart=Total number of years for the investment or loanFV=PV×[n1+i](n×t)PV=FV÷...
Derivation of Compound Interest Formula The compound interest equation/formula can be derived with the help of simple interest formulas as shown below. The formula for SI is: S.I.=(P×R×T)100S.I.=(P×R×T)100 Where; P is the principal amount, R is the rate of interest and T deno...
The above formulas help determine the interest and amount in case of compound interest quickly. NOTE: From the data, it is clear that the interest rate for the first year in compound interest is the same as that in simple interest. PR/100. ...
The Four Formulas So, the basic formula for Compound Interest is: FV = PV (1+r)n FV = Future Value, PV = Present Value, r = Interest Rate (as a decimal value), and n = Number of Periods With that we can work out the Future ValueFVwhen we know the Present ValuePV, the Interes...
