Having trouble with calculations

[Vorstoss]

Hi guys, so I have a pretty simple task here...I feel that I am close, but no cigar. I am basically trying to convert this calculator from excel to c++ code and have a simple output of the Total Commissions to the console. It's not some much that I don't understand the code, its more the math...I think.

So here is my code for the Calculations...

  #include <iostream>

using namespace std;

int main()
{
    double n1,n2,n3,n4,n5,grandTotal,subTotComm,subBrkrOffTopCut,subCommAftBrkrCut,finalTotComm;
    

        cout << "Enter Total Real Estate Price " << endl;
        cin >> n1;
        cout << "Enter your commision percent " << endl;
        cin >> n2;
        cout << "Enter Broker cut percent " << endl;
        cin >> n3;
        cout << "Enter Broke/Agent Split percent " << endl;
        cin >> n4;
        cout << "Enter Partner split percent" << endl;
        cin >> n5;

            n2/=100;
            n3/=100;
            n4/=100;
            n5/=100;

            subTotComm = n1*n2; //D4*D5

            subBrkrOffTopCut = subTotComm*n3;//D6*D7

            subCommAftBrkrCut = subTotComm - n3;//D6-D8

            finalTotComm = subCommAftBrkrCut*n4 ; //D9*D10

            grandTotal = finalTotComm* n5;//D11*D12

            cout << "You total commisions are $" << grandTotal << endl;
   
   return 0;
}

Here is a link to a pic of the excel doc I am working with.

What cells are being calculated together are noted in column F

The excel doc is outputting $4,692.00
My code is outputting $5,099.93

Any help would be appreciated.

The question is: what is the right result? If your formulas are correct the result is correct.

There might be a problem with precision on the excel side or a problem with the formulas on your program side.

I know for a fact that the excel document is 100% correct. I just cant translate the math into C++ :/ I been messing with it for hours and can't get the same results. I must not be understanding percentages right...and percentages is where the problems lies, im almost certain. Thanks for the response..if anyone has an idea let me know.
