Add an outlet to the end of a partially-switched circuit


I am wanting to add an outlet to (what I believe is) the end of a switched circuit. There is only one set of 4 wires coming in to my existing outlet (black, red, neutral, ground). I don't need my new outlet to be switched, so I'm thinking I don't need to run the red wire to my new outlet. Is that correct? I have sketched out what I believe to be the correct wiring connection below.

Also, if I'm not continuing the switch, do I need romex cable with the red wire? Or, can I just use 14/2 cable with black, neutral, and ground?

Thanks in advance!

Right on the money!

You might consider running /3 cable anyway. Every bedroom in our house has a long extension cord circumnavigating the room because the switched outlet (instead of a proper overhead light) is not in the roght place for how we fit out the room. You can just cap off the unused red wire. A future use of the room could swap wires so the switched outlet is in the new location and the present outlet is all unswitched. The hard part is getting wire into the walls!
