Future value equal to present value multiple  1 number value added interest rate divided to

numbers of value divided to interest compounds principal. The future value is compound interest is money beginning present value .

the formula as,

FV=PV*(1+r/n)nt

The  compound interest rate formula as,

r=In(FV/PV)/t

Example ,

 Initial balance 20,000 ,  final balance 19000, surplus 10000 , terms interest compound 10 years

r=20,000*(19000/20,000)/10
