The simple way to say 終點 is the END. (as in beginning and end).
You can also say the FINISH. (as in start and finish).
(Separately 終 can be final, last etc.,點 can be point, spot, etc..
Then 終點 can be combinations formed from them:
final point, final spot, last point, past spot, etc.
But they are not as general as end or finish.)
