Is it worth it to buy a 14 day pass?

Hello,

I am actually in Nagoya already today with 1 friend and going to Kanazawa for business later today 9/17. I did not buy a JR rail pass ahead of time but I see that there is 3 day delivery to hotels in Japan. i want to use the 14 day pass starting this Saturday 9/22 until I leave from Tokyo on 10/5.

I cannot tell if it is worth it to buy individual trips or to get the 14 day pass. There are different prices listed on Hyperdia, I tried to pick the unreserved seats.

Sat 9/22 Kanazawa to Iwakuni (visiting relatives): 5.5 hours 15,760 yen
Sun 9/23 Iwakuni to Hiroshima: 50 min, 760 yen
Sun 9/23 Hiroshima back to Kanazawa: 4 hours, 9350 yen.
I am thinking of touring the areas around Kanazawa locally during the week.
Sat 9/29 Kanazawa to Tokyo: 3 hours and 47 min, 9350 yen, spend 1 week in Tokyo
10/5 fly out of Tokyo Haneda airport (local train?)

I am thinking of getting a 1 week Tokyo Metro pass while in Tokyo.

By my calculations for two adults it came out to be about $900 to buy the tickets individually, vs $1169 for the rail pass. I did not calculate the JR bus fare to tour in Kanazawa but I don't think it should add up to more than $200?

Maybe it is not worth buying the pass, and I just wanted to get confirmation.
