I just figured that 500mL of 100mg unflavored nicotine juice will last me for 15 months, if I vape 6mL per day.
I used Breaktru's eJuice Me Up calculator (which is great, by the way) to make the calculations easy.
eJuice Me Up - e-Juice e-Liquid Recipe Calculator
Here are my calculations to make 2780mL (almost 3 quarts at 946mL per quart) of eliquid. The final result is in parenthesis.
500mL 100mg Unflavored Nicotine Liquid 100% PG (18mg)
1028mL PG (70%)
834mL VG (30%)
417mL Flavoring (PG) (15%)
Total cost is about $165. This includes $20 estimated shipping, Gourmet Vapor (with 40% discount thru 12/15 on nic liquid), TSC ($27 for a gallon of PG), Walmart ($3 for 6 oz of VG), and Perfumers Apprentice ($26 for 16oz of flavoring).
Total cost for 23 bottles of 120mL (or 2760mL total) at FSUSA (at $40 per 120mL) is $920, not including shipping.
Total net savings = $755 (rough estimate)
Per month savings = $50 (rough estimate)
Cost per mL = 5.94 cents (rough estimate)
The reason for posting was I've searched all over to find out how long nicotine liquid will last when stored in a dark, cool place, such as a closet.
Does anyone know?
