In bulk that would come to about the following :
CMJ Frontier 230 gr. = 10¢
Powder (Bulk Titegroup @ 25$ per lb, 4.5gr load) = 1.6¢
Primer (CCI LP @ 25$ per brick of 1000) = 2.5¢
Total = 14.1¢ a pop, which translates to 7$ a box, nearly one third of the price of new manufacture ammunition in this caliber.
Also, since it's a low pressure round, brass lasts 'forever'
I save almost 66% reloading .45, in comparison, I save about 50% reloading 40S&W, and about 15% reloading 9mm, and around 60% loading .44Magnum. Bottom line, .45ACP is one of the common pistol caliber really worth reloading.
