5 ways to save and invest by living sustainably

The climate crisis affects us all, from rising sea levels to plastic-choked oceans. While no one can fix the planet solo, you’d be amazed at how much impact one person can make by living sustainably. And here’s a bonus: sustainable living doesn’t just help the planet, it can help your wallet too.

Let’s start with one of the most overlooked areas of waste and spending: your period.

Why are periods so expensive?

According to the Women’s Environmental Network, the average person uses over 11,000 disposable menstrual products in their lifetime. But if your flow is heavier or your cycle longer, that number can climb to 13,000+ products.

Here’s what that looks like in cost:

Product type	Lifetime cost (approx.)
Budget tampons	$600 / €500 / £440
Premium products	$2,400 / €1,977 / £1,760

That’s a lot of money and a lot of waste.

How to cut period costs sustainably

Switching to Lunette’s reusable period care like the Lunette Cup- is a smart move for your budget and the planet.

Here’s why:

A menstrual cup lasts up to 10 years (often longer with proper care);
Over 37 years of menstruation, you’ll need just 4 cups;
That’s a fraction of the cost of disposables;
You’ll help reduce the 200,000 tonnes of annual waste from single-use period products.

It’s a win-win: less spending, less plastic.

5 smart ways to invest your period savings

Once you’ve made the switch, you could save around $10/month - that’s $600 over 5 years. Here’s how to make that money work for you:

1. Try the cookie jar method

Start simple. Pop that $10 into a jar, envelope, or shoebox each month. It builds the habit and over time, builds your savings.

2. Open a high-interest savings account

Even small amounts grow with interest. Use your monthly savings to build an emergency fund or reach a financial goal. Many online banks offer competitive rates with no minimum deposit.

3. Pay down debt

Every extra dollar counts. Use your savings to chip away at credit card balances or student loans. It’s a small step with big long-term impact and peace of mind.

4. Invest in your skills

Online courses in coding, design, wellness, or even cooking often start at just $10. Upskilling boosts your career, confidence, and creativity.

5. Donate to a cause

Support organizations like City to Sea and their Plastic Free Periods campaign. Your $10 can help protect oceans, reduce waste, and promote sustainable menstruation.

Sustainable living is smart living

Reusable period care isn’t just eco-friendly, it’s economically brilliant. You’ll spend less, waste less, and feel empowered knowing your choices matter. And remember: you don’t have to overhaul your life overnight. Start with one change like switching to a Lunette Cup and build from there.

Your body, your budget, your planet - all deserve care and respect. Sustainable period care is one of the easiest, most impactful ways to invest in your future.

So go ahead - show some love to yourself and the Earth. Make the switch to Lunette today.
