Pris etter mva og fortjenteste i prosent

[sindredit]

Hei,

 

Holder på å starte med webhosting, og driver derfor å programmerer meg et program som jeg skal benytte til fakturering. Holder nå på med varene/tjeneste jeg skal selge og står litt fast på utregning av mva:

 

Har følgende data:

Innpris = 20

Utpris før MVA = 40

MVA = 25

 

Skal regne ut:

Utpris etter MVA

Fortjeneste i prosent

 

På forhånd takk

 

Legger ved PHP-kode for de spessielt intresserte:

           $inp_inventory_category = $_POST['inp_inventory_category'];
           $inp_inventory_category = output_xhtml($inp_inventory_category);
           $inp_inventory_category_mysql = quote_smart($inp_inventory_category);

           $inp_inventory_name = $_POST['inp_inventory_name'];
           $inp_inventory_name = output_xhtml($inp_inventory_name);
           $inp_inventory_name_mysql = quote_smart($inp_inventory_name);

           $inp_inventory_description = $_POST['inp_inventory_description'];
           $inp_inventory_description = output_xhtml($inp_inventory_description);
           $inp_inventory_description = str_replace("<br />", "\n", $inp_inventory_description);
           $inp_inventory_description_mysql = quote_smart($inp_inventory_description);

           $inp_unit = $_POST['inp_unit'];
           $inp_unit = output_xhtml($inp_unit);

           // -> Price after vat

           // -> Gross
           $inp_inventory_gross = $inp_price_bv-$inp_price_in;
           $inp_inventory_gross_mysql = quote_smart($inp_inventory_gross);


           // -> Gross percent


           $result = mysql_query("UPDATE $table_fi_inventory SET inventory_category=$inp_inventory_category_mysql, inventory_name=$inp_inventory_name_mysql, inventory_description=$inp_inventory_description_mysql, inventory_unit=$inp_unit_mysql, inventory_price_in=$inp_price_in_mysql, inventory_price_bv=$inp_price_bv_mysql, inventory_vat=$inp_inventory_vat_mysql, inventory_price_av=$inp_inventory_price_av_mysql, inventory_gross=$inp_inventory_gross_mysql WHERE inventory_id=$id_mysql") or die(mysql_error());
