Power of Compound Interest — Why It Matters If You Start Late

Jun 3, 2025 | Financial Literacy, Flourish, Investing, women on the move

For many women who’ve uprooted their lives to start anew in a different country, financial, social, and cultural resets are constant.

In multiple transitions, financial planning can feel like a distant or even irrelevant goal. The complexity of saving, investing, and planning for retirement often feels overwhelming — and sometimes untimely — especially when time feels short and income feels unsteady.

But here’s a powerful truth:

Even if your resources are limited or irregular, financial empowerment isn’t just about how much you earn. It’s about gaining clarity, building healthy money habits, and making intentional choices with what you do have — all of which lay the foundation for long-term security.

Building financial stability isn’t an overnight process. It’s a journey that begins with small, consistent actions.

Even if investing feels far off, growing your financial knowledge can reduce anxiety, spark confidence, and give you back a sense of control, even in uncertain times.

 

What is compound interest?

Imagine planting a small seed in fertile soil. At first, progress feels slow — a sprout here, a leaf there. But with time, care, and the right conditions, that seed doesn’t just grow. It multiplies — expanding its roots, stretching upward, and blooming year after year.

That’s exactly how compound interest works.

It’s not just about earning on your original savings — it’s about your returns earning their own returns. Interest earns interest, creating a snowball effect that gathers momentum the longer it’s left to grow.

Even with modest beginnings, your money can grow quietly and steadily in the background, especially when nurtured with consistency and time.

For women navigating life transitions, migration, or interrupted careers, this concept offers something powerful: a chance to grow wealth not only from what you have, but from how you use time to your advantage.

A Timeless Rule to Remember: The Rule of 72

The Rule of 72 is a simple mental math shortcut to estimate how long it takes for your money to double through compound interest.

Here’s how it works:
Just divide 72 by your expected annual return (in per cent), and you’ll get a rough idea of how many years it will take to double your investment.

Why 72?
It’s not magic — it’s math. The number 72 works well with typical growth rates and compound interest patterns. And best of all, it’s easy to calculate in your head.

 

For example:

At a modest 6% annual growth rate, your investment would double in about 12 years.

→ 72 ÷ 6 = 12

For women who often start later, pause careers, or support extended family, this simple rule is a reminder that time still has power, and every small investment you make today can quietly double tomorrow.

 

Real-World Glimpse — Starting Small Still Matters

Let’s say you invest €10,000 at age 40, earning a steady 6% return annually.
By age 65, that could grow to approximately €43,000.

Now imagine if you earned only simple interest on that €10,000 — no reinvesting, no compounding — you’d have just €25,000.

That’s a difference of €18,000 — money you didn’t actively work for, but earned quietly over time.

👉🏽 Whether you start with €10,000 or €100, the message is the same:
Compound interest rewards consistency, not perfection.

For women juggling major life changes, migration, or family responsibilities, this is a powerful reminder:
You don’t need to start big. You just need to start.

 

🔎 Grassroots Example — Grow Steadily, Start Simply

Let’s say you commit to saving €100 per month, starting at age 40, and earn an average 6% annual return.

By the time you’re 65, your total contributions would be €30,000 — but thanks to compound interest, your savings could grow to around €70,000.

That’s €40,000 in growth — earned quietly in the background through consistent action.

👉🏽 You don’t need a big salary or a lump sum. You need time, commitment, and belief that your small actions today can lead to big outcomes tomorrow.

This is a protective money strategy in action:

A buffer.

A foundation.

A future built from steady, doable steps.

Compound Interest in Real Life: A Strategy That Still Works — Even in a Volatile 2025

Yes — this strategy still holds power in today’s uncertain world. Here’s why:

🌱 1. It’s not about timing the market — it’s about time in the market.
Even with fluctuating returns and global uncertainty, consistent contributions over time still create tangible growth. Markets rise and fall, but the long-term trend has historically rewarded those who stay invested, especially over 20–25 years.

 

💶 2. €100/month is still realistic and flexible.
You don’t need to start big. Even beginning with €25 or €50/month and increasing when possible can make a meaningful difference. What matters most? Getting into the habit of paying yourself first.

 

📈 3.6% is a grounded, achievable estimate.
While returns vary, a well-diversified long-term investment, such as a low-fee index fund, can still average 5–7% annually. Some years are leaner, some are stronger. But the principle of compound growth still works.

 

🤝 4. Especially for migrant women or women in transition:
If you’ve ever felt “behind,” or like wealth-building isn’t for you, this strategy says:
Start where you are. Build with what you have. Grow what you can.
You don’t need perfection. You need progress.
