How Much Can You Save by Switching to a Menstrual Disc?
Periods are a part of life for millions of people - but the way we manage them has a huge impact on our wallets and the planet. If you’ve ever wondered how much difference one small change can make, you’re in the right place.
In this article, we’ll break down the real costs of disposable products, the environmental footprint they leave behind, and how switching to a reusable menstrual disc can save you money and reduce waste. We’ve also included our interactive impact calculator so you can see exactly what your personal savings could look like.
The Hidden Cost of Disposable Period Products
On average, someone who menstruates will have around 450 periods over their lifetime. If you’re using disposable pads or tampons, that means buying and throwing away thousands of products - often without realising how quickly the cost adds up.
Here in Australia, a box of tampons or pads can cost anywhere from $4 to $8, and many people go through one or more boxes per cycle. When you multiply that by 12 periods per year, it’s not unusual to spend over $120 a year on disposables alone. Over five years, that’s easily $600 - and that’s being conservative.
Cost isn’t the only concern. Each disposable pad or tampon takes resources to produce - from cotton and synthetic materials to the packaging and transport. Once used, they end up in landfill, where they can take hundreds of years to break down.
Why a Menstrual Disc Can Make a Difference
A high-quality reusable menstrual disc, like the my mimi menstrual disc, is designed to last for years. Instead of buying boxes of disposables every month, you can invest once and reuse the same product cycle after cycle.
Here’s why it matters:
- Long-term savings: A disc can last up to five years with proper care. Instead of spending $600 or more over that period, you could spend just $44.95 - about 83¢ a month.
- Less waste: One disc replaces around 1,200 pads or tampons over its lifetime.
- Comfort and convenience: A disc can be worn for up to 8–12 hours, holds more than a tampon, and is suitable for activities like swimming, running, and yoga.
Your Savings, Your Impact
Everyone’s cycle is different. How often you have your period, how heavy your flow is, and what you currently use all affect how much you spend - and how much waste you create. That’s why we’ve built a simple Impact Calculator so you can see your own numbers.
Try it now:
- Adjust the sliders to match how often you have your period, how many products you use per cycle, and what you pay for disposables.
- See your personalised results: how many disposables you’d avoid, how much water and carbon you’d save, and how much money could stay in your pocket.

The Environmental Benefit
Saving money is great, and the environmental gains are just as important. Every disposable pad or tampon you avoid helps to:
- Reduce landfill waste: Pads contain plastics, and tampons are often wrapped in plastic.
- Cut carbon emissions: Manufacturing and transporting disposables uses energy and produces CO₂.
- Conserve water: Cotton production is water-intensive. Avoiding disposables helps reduce water consumption.
With one reusable disc, you’re making a small but powerful change that adds up over time - especially as more people make the switch.
A Switch That Pays for Itself
Think of a menstrual disc as an investment. If you buy one disc today, it can pay for itself after just a few cycles compared to what you’d spend on disposables. After that, every cycle is savings - and less waste in landfill.
For example, if you normally spend $10 per cycle on disposables, you’ll break even in under five months. By the end of five years, you could save hundreds of dollars.
Making the Change
Switching to a menstrual disc might feel like a big step, but most users find that after a couple of cycles they don’t want to go back. Here are a few tips to make the transition easier:
- Choose the right size: The my mimi menstrual disc comes in two sizes - Small for those under 30 who haven’t given birth vaginally, and Large for those over 30 or who have given birth vaginally.
- Learn the fold and placement: It can take a couple of tries to get the hang of inserting and removing a disc comfortably. Our how-to guides and videos can help.
- Give yourself a few cycles: Your body will adapt, and your confidence will grow.
It’s About More Than Money
Yes, the savings are significant, but switching to a menstrual disc is also about comfort, confidence, and caring for the planet. It’s a way to take control of your period care in a way that supports both you and the environment.
Whether you’re motivated by reducing waste, cutting costs, or simply wanting a more convenient option, the benefits add up quickly.
