Natural & Eco-Friendly Laundry Soaps Price Comparison

Natural & Eco-Friendly Laundry Soaps Price Comparison Image 1

All of the laundry soap brands listed below are considered to be natural and eco-friendly.

I also wanted to compare prices, because no matter how well something works, for most of us price is still a major deciding factor.

Below is a chart that compares 6 natural laundry soap brands:

  • Charlies Soap Laundry Powder
  • Country Save Laundry Powder
  • Earth Berries Soap Nuts
  • Nellie’s Laundry Soda
  • Rocking Green Classic Rock
  • Seventh Generation Laundry Liquid

The chart shows their prices when bought on various websites, or, through the natural foods co-op some people can buy from.

Here’s the final price comparison, starting with the cheapest:

  1. Country Save10.6 cents per load
  2. Earth’s Berries Soap Nuts – 10-13 cents per load
  3. Charlie’s Soap17 cents per load
  4. Nellie’s Laundry Soda24 cents per load
  5. Seventh Generation Laundry 2x Liquid24 cents per load
  6. Rockin’ Green30 cents per load

We have compared based on their average size package, or the smallest packaging that I could find on each website.

It should also be noted that we based the per-load cost on the amount that would be used by a regular washer, not a HE washer. A HE washer uses only 1/2 the amount of soap, for most brands, though not all.

How to Save

Some of these brands do come in very large bulk

Charlie’s Soap has a huge bucket, and so does Nellie’s.

Seventh Generation can be bought in large cases on many sites (Amazon and Soap.com, for instance), or, in much bigger sizes from a co-op.

Country Save can be purchased in massive boxes and Earth’s Berries soap nuts can be bought in up to 300-400 wash packages.

Rockin’ Green does also have a 90/180 load size, which breaks down slightly cheaper.

How to Make Homemade Laundry Detergent

For those who are happy with DIY laundry soaps, none of these store bought laundry detergents beats the cost saving cost-per-load of potentially $0.03c when you make your own homemade laundry detergent!


Homemade laundry detergent ingredients on a table
  • 18 cups of water
  • 1 Dr. Bronner’s Peppermint Bar Soap, or Fels Naptha soap bar
  • 1 cup of Arm & Hammer Super Washing Soda (Baking Soda will not work – It must have sodium carbonate)
  • 1/2 cup of Borax
  • 3 gallons of hot water
  • 5 gallon bucket


Step 1 – Grate the Soap

Grate the Dr Bronner’s soap, or Fels Naptha soap, using a food processor or a hand grater. (Tip: This will help the soap dissolve quickly.)

Let it sit overnight and then it is all ready to be used.

When using homemade laundry deterrent the cost per load can be as low as 0.03c.

Here is how to calculate the cost for 4 gallons of homemade laundry detergent.

  • 1 bar Fels Naptha at $1.29
  • 55 oz box Arm & Hammer Super Washing Soda at $2.75 (1 cup cost .40¢)
  • 76 oz box Borax at $3.79 (1/2 cup cost .20¢)
  • 4 gallons = 64 cups or 64 heavily soiled loads
  • Total cost per load = 0.03c


This review really just looked at a smattering of the brands that are out there, but I always find it so eye-opening to do this kind of detailed cost analysis and really see the numbers for myself!

We compared brands based on cleanliness of clothes, scent, ease of use, how clean they rinsed, how they worked for cloth diapers, and whether we would purchase them or not.

  1. This is a wonderful review/article! Thank you so much! I bought some eco-friendly detergent from Costco and decided that I don’t really like it and am going to switch to something else once it runs out. This article is wonderful for helping me decide what I want to try next! Thanks again!

  2. Thanks! This is really helpful!

    I use Country Save, partly because the price is great, partly because I can get it on Amazon, and partly because nobody in my super-sensitive-skinned family has an issue with it, and it works great on our cloth diapers!

  3. For now, I use the one I can buy at Costco. I want to make mine.
    I’m very difficult in the choice of my soap. I found them to perfum most of the time that why I want to make it myself.
    In your review, you talk about how much loads the container do but some are concentrate, some have more water than the other….Is that take a place in your article?
    Thank you.

  4. I am a fan of Rockin’ Green but the price and SHIPPING gets me every time and it’s just not worth it. I stumbled on to Country Save and I LOVE it more than Rockin’ Green and the price is so perfect!!! I use it for all my laundry including my cloth diaper prefolds and I haven’t had any stink or repelling issues since I started (5months ago!!). I’ve even given Country Save as a baby shower gift. Thanks for your article. :)

  5. @m-a, I didn’t take that into consideration, because it just made the comparisons that much more difficult. I stuck with the load numbers as specified by the company, to keep things simple.

  6. @Esther, No, I haven’t yet. I do use Dr. Bronner’s castile soap extensively, but not the Sals Suds. So I’d be interested to hear what others think of it!

  7. I use BioKleen for our laundry. I have used the powder, but at the moment I am using the liquid as it was on sale and less expensive the last time I purchased it. I like that it cleans and rinses well, and that our sensitive skin issues have gone away since using it.

    For the person who asked above, I have used Dr. Bronner’s in a pinch, and it worked well in the few loads that I used it. However, the cost breakdown was more expensive than I wanted to pay for laundry detergent. On the other hand, since it can be used for laundry, dishes, and general cleaning nearly anywhere in the house, it might be worth the purchase to just have one product for all of those needs. Something for me to think about…

  8. I love Charlies – big fan. I’m going to have to order some Nellie’s. Currently, I’m using the homemade because I can’t get Charlie’s locally in powder form. I like that I can make it super cheap, but it does leave a residue on the side of my machine. I think it does an ok job, but I think the commercially made does a bit better cleanliness wise. I think they get the product much better distributed than what I can do. But, I’m going to keep playing with it.

  9. We love Charlie’s Soap. We were buying the 80 load bags for about $11 in a nearby town. Last February we bought the 5 gallon bucket online and still have half of it left. Prior to that, we made our own soap. Charlie’s actually was slightly cheaper for us. Your clothes simply smell clean. We still have to pre-treat some stains. I rarely use fabric softener either, just with a few things that get static cling. I had to wash my daughter’s favorite stuffed dog and it came out much softer and cleaner with Charlie’s that our previous soap.

  10. Our White Plains, NY Whole Foods had the 64 load Biokleen liquid on sale this week (I shopped on 11/1) for $8.99. I thought it was a misprint! Thank God for bargains! I stocked up and bought some for friends who have wanted to give it a test drive.

    However. I will buy & try the Nellies with great anticipation.

    Thanks for this! I have friends who cloth diaper (best for them has been purchasing a “personal washing machine” just for diapers, but I recently enjoyed a sample of Rockin’ Green.

    I’m an essential oils gal myself, and I add a capful of Young Living’s Thieves Household Cleaner or a few drops of Purification oil blend to my BioKleen (Grapefruit variety pink package) extra stinky loads. I find that the Biokleen has been fantastic, and recently I’ve used a capful of their BacOut for loads with shower curtains and steamer/mop covers.
