Which is the correct phrase to say saving money?


I like to tell that I am saving money to buy Mac Book . So two sentence come
to my mind , which one is more suitable to use ..

  1. 僕はMACBOOKを買うためにお金を **貯金** しています。
  2. 僕はMACBOOKを買うためにお金を **節約** しています。




I would suggest 「お金を貯{た}めている。」or a more polite conjugation if circumstances
require.

節約 would mean you are being 'economical' with your usage of money, rather than
emphasizing the saving of money.

貯金している might be alright, but I believe it has a stronger connotation of the
physical accumulation of money, rather than the more abstract sense of just
'saving money'. Also, as @naruto さん mentions, it is tautological.
