Here's a breakdown from another site where the gal did a LOT more math than I did. She doesn't use the DAWN that I add into mine, so that may add a few pennies.
----------------------------------------------------------------------------
Here is the breakdown of my costs and how I came up with those numbers (I am using the prices I paid for these items and you may find your price varies some based on what you pay):
Fels Naptha: $1.12 for a 5.5 oz bar. The recipes says use a 1/3 of a bar. I calculated 2 oz. just to make the math a little easier. The cost of the Fels Naptha per batch is: .40 cents
Washing Soda: $2.23 for a 55 oz. box. This came to .17 cents per batch. I calculated how much per oz (2.23 divided by 55) and then weighed a half cup of washing soda (4.2oz.) and multiplied my per oz. price by 4.2
Borax: $3.27 for a 76 oz. box. This came to .14 cents per batch. Did the same calculations as above, however a 1/2 cup of borax weighs 3.5 oz.
For the final numbers I have .40 + .17 + .14 = .71 for 2 gallons of laundry detergent.
----------------------------------------------------------------
How many loads can you do with 2 gallons? 2 X 64 oz=128 oz/ 4 oz per load = 32 loads. So, .71/32= JUST OVER 2 cents/load. I'm not doing more math than that! LOL!
