Idea for Troop Tally or Expense

Okay, so I read through multiple different threads to see if this had been suggested before and I didn't see anything related. If this has been suggested before, I apologize.

I was talking with my brother the other day, he and I both play a fair amount (everyday), and I was having a hard time holding onto elixir. I would battle and then train new troops and not doing a really good job of keeping track of how much I needed to look for when battling to at least break even. I was wondering if you guys have considered having a tally of how much your troops are costing you to train and how much you would need to look for to be in on the positive side of battling. For location, I was thinking right under the pop-up screen in the barracks. It doesn't have to be big. Just a running tally of how much the troops cost, as a collective in all the barracks. Again, if this has been mentioned, I am sorry. I just joined the forum today. Thanks so much for your hard work. I love Clash of Clans. Cheers.

I created something in excel, one tab is a calculator for figuring out the costs of my attacks. the second is a more generic one I can use to calculate the cost of attacks against me. Bot figure out how much you spent of each resource and how much made and gives the net profit in the end.

If there is a place on this forum to place a files others can download I would happily put it up there for anyone to grab if they wanted it.
