When it comes to saving money in the laundry, nothing beats Dirt. While many liquid laundry detergent brands are full of water, our ultra-concentrated formula isn’t.
Packaged in a reusable glass refill dispenser bottle, you can measure the exact amount of detergent you need with zero waste – that means, no more spillage and more money going down the drain.
But if you want to get into the nitty gritty and truly reduce your washing expenses, it’s important to look into the only true economic metric in laundry – cost per load. This refers to the cost it takes to do one load of laundry.
Comparing Cost Per Load
Let’s say you wash three loads of laundry per week, amounting to 156 loads per year, we want to show you the true cost of what you’re paying with us versus the supermarket brands.
How did we crunch the numbers? Well, we started our research at Woolworths on April 3, 2024, and purchased Dynamo, OMO, Biozet and Ecostore full price in their regular and bulk sized packs. We then calculated their individual cost per load and multiplied it by three (loads of washing per week), and again by 52 (weeks) and the results speak for themselves.
Clearly, buying bulk is more economical, no matter what the brand. Not to mention a more sustainable choice as you’re using less plastic. However, what stands out is the massive difference in cost per year when you compare us to the supermarket brands. With the cost of living at a staggering high, there’s no better time to make the switch to a more environmentally-friendly and cost-effective option. Hint: yep, that’s us.

Bigger is better
At Dirt, we offer a 3L bulk size refill of our Original Laundry Detergent because we believe it’s the most economical and environmental way to buy detergent at only 29c per load, with 210 loads per pack.
Our price is low because we don't ship you water (instead, our detergent is 8x ultra-concentrated), and we don't pass our margins onto the supermarket majors. While competitor costs can be offset by supermarket discounting, we've always thought the more decent thing to do is to set a value driven price and keep it consistent. And while we love laundry, we know it’s not on the top of everyone’s priority list. This way, you can rest easy, stock up and clean your clothes all year ‘round without compromising your budget or the planet – now that feels good!
And there you have it, the true cost per load of your favourite laundry detergent brands and why Dirt is your number one choice when it comes to saving money and helping the environment.
One Last Thing - Plastic Per Load
While we're on the topic of cost per load, we'd be amiss not to mention perhaps the most mind-boggling statistic of all - the environmental costs.
| Plastic per load | Bottle Weight | Loads | |
| 2L Bottle | 4.9g | 196g | 40 |
| 450ml Refill | 0.62g | 20g | 32 |
And this is not including the fact that more than 50% of the refill packs we send are on their second life or third life.
Cost per load can be measured in more ways than one, but we urge you to please stay vigilant in the laundry - it can be quite sticky business!
