Albert Einstein once called it the eighth wonder of the world. Warren Buffett described it simply “He who understands it, earns it; he who doesn’t, pays it”.

They were both talking about compounding, the quiet force that turns time and patience into growth.

What is Compounding?

Compounding is the process of earning interest on both your original investment and the interest already generated. Over time, this creates a snowball effect: the longer your funds remain invested, the more powerful the compounding becomes. It rewards consistency and patience rather than frequent changes or short-term decisions.

How it Works

Consider an example where €50,000 is invested at an annual return of 5%:

At the end of the first year, you have €52,500. In the second year, you earn 5%  on €52,500 giving you €55,125. After ten years, your original would have grown to just over €81,445

That is the power of compounding. It is not about chasing the highest return every year, but about staying invested and letting time do its work.

Why It Matters for Wealth Management

In wealth management, compounding is often the quiet driver of long-term success. Starting early gives your capital more years to benefit from this effect. Regular contributions and reinvested dividends can make a significant difference over time.

Compounding and Retirement Planning

Compounding plays an even bigger role in retirement and pension planning. Each pension contribution benefits from tax relief and often an employer contribution. The growth on those contributions is then reinvested, which in turn generates more growth. Over the years, that compounding effect becomes very powerful.

Consider two investors each saving €1,000 per month with an average annual growth of 5%.

The person who starts ten years earlier ends up with nearly double the retirement fund, not because they took more risk or earned a higher return, but simply because their money had more time to compound.

This is one of the clearest examples of how time in the market outweighs timing the market.
