Nice little program.
After one year you get about a 20% loss in concentration by natural decomposition. So you need a fudge factor.
Concentration loss increases with dilution and with higher temperatures. The "ready to use" product probably has the worse shelf life.

PureBright Bleach 768 oz @ $19.05 = $0.02 per oz: Sodium Hypochlorite = 6.000%
Clorox Bleach 64 oz @ $10.40 = $0.16 per oz: Sodium Hypochlorite = 8.250%
Cleaner Bleach 32 oz @ $1.80 = $0.06 per oz: Sodium Hypochlorite = 2.000%
Anasept 15 oz @ $21.00 = $1.40 per oz: Sodium Hypochlorite = 0.057%
PureBright Potency has degraded from 6.00% to 5.93% since {2018,9,1,0,0,0}.
10.79 oz ($0.27) of PureBright Bleach makes 32 oz of a solution = Cleaner Bleach($1.80)
PureBright has 71% of the Sodium Hypochlorite content of Clorox.
Therefore; 39% more PureBright is required to match the Sodium
Hypochlorite Content of Clorox, hence the relative cost of PureBright
compared to Clorox = $0.035/oz. Even so, ***Clorox cost = 4.71 times**
the adjusted cost/oz of PureBright.
PureBright has 104 times the Sodium Hypochlorite content of Anasept.
0.14 fluid oz (1.0 tsp) of PureBright costs only $0.004,
yet makes a 15 fluid oz solution with Sodium Hypochlorite
content comparable to that of Anasept Antimicrobial
Skin & Wound Cleaner which costs ~$21.00.
One Gallon of PureBright can make the equivalent of
888 15 oz bottles of Anasept, which would cost $18,643.08
