I'm trying to build myself a budget program but my calculations for percent arnt working properly.

What i want is lets say u have a 400$ pay check
and u want to find out what 30% of that is and then put it into its own value
how would i go about doing so

You say your calculations aren't working? What do you mean?
And you would multiply the paycheck by 0.3 to get 30% of it.

double paycheck=400;
double balance =0;

balance =paycheck*0.3;

printf ("%.2d"+ balance);

Why are you using printf, printf is a C function to output items to a screen, you should be using std::cout since this is C++ not C.

Further more the code can be shortened a bit more to

double paycheck=400;
double balance = paycheck * 0.3;

Those calculations should work, if they don't already.
