var percentage = parseInt($("#Btw option:selected" ).val()); NewBtw = (subtotal / 100) * percentage; Totaal = (subtotal + NewBtw); — murtaza, Mar 24 '15 at 09:10
murtaza, please post the current relevant HTML code. We have no idea of how your — briosheje, Mar 24 '15 at 09:25
You haven't shown the HTML that calculates subtotal, i.e. all the .price elements. **Again** without all the information no one can answer this! — Liam, Mar 24 '15 at 10:08
There's also a mysterious method called roundNumber that's missing. Why don't you create a https://jsfiddle.net/ for this? I also think you should be able to figure this out yourself if you simply [debug your javascript code](http://stackoverflow.com/questions/988363/how-can-i-debug-my-javascript-code) — Liam, Mar 24 '15 at 10:10
I have paste the code in jsfiddle.net https://jsfiddle.net/7L4jvage/ — murtaza, Mar 24 '15 at 10:36

this sin't an answer to the question. I'm guessing you wanted to edit your question, so I've added the details for you and flagged this for moderator attention. It would be better if you delete this answer though. Answers should **only** be used to provide answers! not extra details for the question – Liam Mar 24 '15 at 09:41
