Net Present Value in the controller

Hello Experts,

Can you please help me placing the below formula on VF Controller Page.

The following is the formula for calculating NPV: 
User-added image
Ct = net cash inflow during the period
Co= initial investment
r = discount rate, and
t = number of time periods 

Thank you so much .

public class sampleController{

public static void cal{
Decimal Ct;
Decimal C0;
Decimal r;
Integer t,i;

Decimal myDecimal = 1+r;

Decimal decValue = myDecimal.pow(t);

Decimal fractionValue = (ct/decValue)-C0;

Decimal finalValue=0.00;

for(i=1;i<=t;i++){

finalValue+=fractionValue;

}

}
}
HI Vadm,

You can change the data type to double if that's your req. But this should work fine with some minor tweaking.

Thanks,

Gautam Kumar.
