Often as a stay at home mom I find myself questioning my “economic contribution” to our family finances. Of course I know the basics; we are cutting day care costs, a second car, and a work wardrobe completely out of the budget. And I also know that there are several immeasurable benefits of me being at home every day…so many that it is a completely different blog post. Perhaps another day for that one. Even in light of these facts, I began to think about what more I could do to make a substantial contribution to our finances. I wanted to show my husband that I truly value the time and hard work that he puts into providing for his family. To do this I have committed myself to being as wise with the money he brings in as I possibly can. Wisdom with money nearly always equals two things: giving and frugality. Giving, because we have been blessed, and frugality, so that we can give. So, while I don’t have a job that brings in the dollars, what I do have, as a stay at home mom, is time. And with this time, I thought, how I can I spend 10 extra minutes to save 10 extra dollars?
I decided to start small, rather than jump in head first making radical changes to our lifestyle all at once. I want my changes to be maintainable, after all. So I’ve committed to two small changes this month: making oatmeal instead of using boxed cereal and trying my hand at homemade laundry soap rather than name brand. What follows are my calculations of time spent, money spent and money saved. After which I have included picture by picture instructions on how I made my laundry soap. (Thank you to Jeana M. for taking the photos and helping with the process!
Time
Each morning I spent 10 minutes making oatmeal for myself and my son.
Last night I spent about 25 minutes making laundry soap (and it was my very first time!)
Calculations
For the oatmeal vs. cereal comparison, I chose to use Cheerios, a mid-priced, common cereal.
Average price of Cheerios, $2.88 per 14 oz box, each box containing 14 servings.
Average price of oatmeal, $1.29 per 1lb canister, each canister containing 30 servings.
Joel and I usually consume 2 servings of either one in any given morning.
Each serving of cereal costs $0.20 (2.88 divided by 14 equals 0.2). So, take that number by 2 and you get $0.40 per morning. That number times 30 (an average month) equals about $12.00.
Each serving of oatmeal costs $0.04 (1.29 divided by 30 equals 0.04). That number times 2 equals $0.08 per morning, and times 30 equals about $2.40 a month.
By spending an extra 10 minutes every morning, I can save my family, literally, about $10 a month!
What you will need:
- Washing Soda – 1/2 a cup
- Borax -1/2 a cup
- Ivory Soap – 1 Bar
- Watar
The laundry soap calculations were a little more complicated, but here is how we figured that I am able to launder my family’s clothing for $0.01 per load!
Washing Soda is $2.74 or a 55 oz box. Per batch of laundry soap, you use 1/2 a cup, or 4.2 oz by weight.
$2.74 divided by 55 oz equals $0.05 per oz. $0.05 times 4.2 oz equals $0.21 per batch of soap.
Borax is $3.95 for a 76 oz box. Per batch of laundry soap you use 1/2 a cup, or 3.5 oz by weight.
$3.95 divided by 76 equals $0.05 per oz. $0.05 times 3.5 equals $0.18 per batch of soap.
Ivory Soap is 3 bars for $1. Per batch of laundry soap you use 1 bar, which equals $0.33 per batch.
So…
$0.21 plus $0.18 plus $0.33 equals $0.72 per batch of laundry soap.
Each batch makes two gallons and each load requires 1/2 a cup of soap. There are 16 cups in a gallon, times two equals 32 cups in a batch. 1/2 a cup per load makes a batch last 64 loads.
$0.72 (the price of a batch) divided by 64 (number of loads a batch will wash) equals…drumroll please…
$0.013 per load (which, of course rounds to about a penny per load!)
Here is the recipe I used and, after washing 3 loads of laundry in it, I can personally attest that it does leave your clothes clean and fresh!
Laundry soap instructions:

Step 1. Gather your supplies. You will need 1/2 cup Borax, 1/2 cup Washing Soda and one bar of Ivory Soap, grated. Plus, a cheese grater, a large pot, a big bucket and LOTS of water.

Step 2. Grate your bar of soap as fine as you can and add it to your large pot. The finer you grate it the better it will melt. I used my mixer attachment to make this go quicker, but a good old cheese grater works too.

Step 3. Add 6 cups of water to the pot and heat it up until the soap melts.

Step 4. Add 1/2 cup of borax and 1/2 cup of washing soda to hot soap mixture and stir until dissolved.

Step 5. Add 4 cups of hot water into your large bucket. Stir in your soap mixture. Then add 1 gallon (16 cups) plus an extra 6 cups of water to all that. Stir.

Step 6. Allow to sit overnight. I just covered my bucket with a tea towel and left it on the counter. In the morning your finished laundry soap will have a chunky/soupy consistency. This means you did it correctly. Now you can pour it into a container of your choice. I just used old laundry soap containers that I happened to still have in the basement; I cleaned them out first, of course. Also you can add an essential oil if you wish. The recipe is unscented, which still got my clothes clean and fresh, but I believe I will go get a lavender essential oil for mine. It takes about 10-15 drops and you just add it after the mixture has cooled.
The information I gathered for this came from several, but several different web sites that offered recipes on how to make your own homemade laundry soap. There were many variations and I just chose this recipe because I happened to have Ivory Soap on hand already. All it takes is a Google search of “homemade laundry soap” and you will find many different ways to prepare it, even a couple recipes for a powder type soap if that is what you prefer or if you are a little short on time. (However, the powdered type is not as cost effective as the liquid). Happy soap making!
