Like many of you with a female living in the home, keeping your TP preps up to snuff can be difficult. For me, a family of four (me, wife, 6 y/o son, 5 y/o daughter), I find my TP preps are always depleted. So, after buying yet another 12 pack today, I thought I would do some fun TP arithmetic just to see how much it would cost, and space necessary to store, a 6 month, 1 year, and 5 year supply of TP preps for a SHTF/TEOTWAWKI scenario. Your TP needs may differ greatly from mine, and how much you pay, what type you use (e.g. 1-ply vs 2-ply), etc. may vary. This exercise was done mostly for fun.
First off, I estimated how much TP my household currently uses. For my family, this is ~408 rolls of TP per year (we use the 2-ply "double rolls" stuff). We buy our TP from Aldis (a local low cost grocer) for $4.69/12 pack (tack on MN sales tax of 6.875% and the total is $5.01/12 pack). This equates to $0.42/roll (rounded up). This comes out to an annual TP cost of $171. If our TP consumption were not to change after a SHTF/TEOTWAWKI scenario (i.e. using less, switching to 1-ply, etc.), then it would cost $86 to stock up a 6 mo supply, $171 to stock up a 1 yr supply, and $855 to stock up a 5 yr supply.
Now, the 6 month, and even 1 year cost aren't that big of an expense if you were to run out today and buy it all in one lump sum (e.g. Texas size asteroid is going to hit the Earth in 2 days and you need TP for the coming apocalypse). But, where the numbers really start to get fun is when we talk about space needed to store TP for these durations. A 12 pack of 2-ply TP has the following dimensions: L=13", W= 9", H=9" and a cubic volume of 1,053 cubic inches. A 6 month supply would consist of 17 twelve-packs (rounded up) which would take up 17,901 cubic inches of space (or 10 cubic feet of space). A 1 year supply would consist of 34 twelve-packs which would take up 35,802 cubic inches of space (or 21 cubic feet of space). And the 5 year supply would consist of 170 twelve-packs which would take up 179,010 cubic inches of space (or 104 cubic feet of space).
For those, like me, who have a tough time conceptualizing how much space cubic feet takes up, here are some conversion:
- 6 mo supply (costs $86 and would take up 10 cubic feet) = stack would be about 2.5' high, 2.5' wide, 1.5' deep
- 1 yr supply (costs $171 and would take up 21 cubic feet) = stack would be about 3' high, 3' wide, 2.2' deep
- 5 yr supply (costs $855 and would take up 104 cubic feet) = stack would be about 5' high, 5' wide, 4.2' deep
Of course a reality we must recognize is that if this much TP were available in your home, the ladies in the house would probably just use more and all my numbers would be pointless!
Anyway, was fun. Hope you enjoy!
