The Power of Compound Interest - The 8th Wonder of the world

“Compound interest is the eighth wonder of the world. He who understands it, earns it; he who doesn't, pays it.” -- Albert Einstein

The Power of Compound Interest

What Is Compound Interest (and Why It Matters)

When it comes to building long-term wealth, few concepts are as quietly powerful as compound interest. It’s the process of earning returns on both your original investment and the growth that follows — a snowball effect that turns small beginnings into substantial gains over time.

At its core, compound interest means your money works for you — and then your returns start working too.

For example, if you invest $1,000 at a 10% annual return, you’ll have $1,100 after the first year. In year two, you earn interest on $1,100 — not just the original $1,000 — and the effect compounds year after year.

Over decades, this exponential curve creates what Einstein reportedly called “the eighth wonder of the world.” But not all investments compound equally.

The Limitations of Traditional Savings and CDs

Traditional accounts like savings accounts and certificates of deposit (CDs) offer predictability — but at a cost. While some promotional CDs currently reach around 4% APY, those are exceptions. Most CDs average closer to 2–3%, especially once you account for longer terms or non-promotional rates.

That might sound stable, but when you factor in inflation, those returns lose much of their impact. Inflation steadily reduces your purchasing power — meaning the same dollar buys less over time. In fact, over the past 12 months, inflation measured by The Consumer Price Index (CPI) has been about 2.9 %.

So if your CD is earning 4% APY, your real return after inflation is only about 1.1 % (4% − 2.9%). And if your CD yields closer to 3%, the real gain might be near 0.1 % or even negative.

(For those sitting on expiring CDs or low-yield accounts, you might be wondering how to make your money work harder — we cover that next in our article on cashing out of a CD and turning to real estate.)

How Real Estate Compounds Differently

Real estate offers a more dynamic form of compounding. It grows through both cash flow and appreciation — meaning your returns can build on multiple fronts.

  1. Rental income provides recurring cash flow that can be reinvested to purchase additional shares or properties.

  2. Property appreciation adds long-term value, increasing the base your future returns are built upon.

Remember how inflation worked against you with savings or CDs? With real estate, it often does the opposite. Because homes are tangible assets with intrinsic value and real-world utility, their prices tend to rise along with inflation — sometimes even faster. As the cost of goods and materials increases, so does the cost of housing, which naturally lifts property values over time.

Together, these factors create a dual-compounding effect that not only outpaces traditional interest-based accounts but also turns inflation into an ally rather than a threat.

Compounding Through Real Estate Shares

With Realbricks, investors can gain exposure to real estate by purchasing shares of individual properties with a minimum investment of $100. Each share represents an interest in a carefully vetted long-term rental property that has projected dividend distributions from rental income on a quarterly basis and allows investors to gain exposure in changes in property value over time.

By choosing to reinvest distributions, investors may increase their overall exposure to real estate over time. This approach can help build momentum through reinvestment, similar in concept to compounding, while remaining tied to tangible, income-generating assets.

The Real Secret of Compounding

Compounding doesn’t require perfect timing or massive capital — it just takes discipline. Whether you’re building savings or investing in real estate, the earlier you start, the more time your returns have to multiply.

For example, let’s say you invest $100 a month and earn an average annual return of 8%. After 10 years, you’d have around $18,000 — and after 20 years, that amount could grow to over $59,000.

That’s the quiet magic of compound interest: steady contributions over time can create exponential results. When applied to real estate — with both cash flow and appreciation working in your favor — that effect becomes even more powerful.

At Realbricks, investors have experienced an annualized return of roughly 8.25%, with four consecutive quarterly dividends, 2.25% in Q4 2024, 2% in Q1 2025, 2.00% Q2 2025, and 2% in Q3 of 2025, paid from rental income. It’s a tangible example of compounding in action — real assets generating consistent returns, quarter after quarter.

Time can be an important factor in investing. Realbricks allows investors to access real estate assets over time with a low minimum investment of $100.
