The Power of Compound Interest with XEQT: How Your Money Makes Money Makes Money

I will never forget the month it happened.

I had been investing $500 a month into XEQT for a little over three years. It was a Tuesday night, and I was idly scrolling through my Wealthsimple account when I noticed something that stopped me cold. My portfolio had gained $620 that month – more than my $500 contribution.

My money had earned more money that month than I had put in.

I remember sitting there, staring at the screen, trying to process what I was seeing. I had read about compound interest a hundred times. I understood it intellectually. But that was the first time I felt it. My investments were no longer just a savings account with extra steps. They were a machine. A machine that was starting to feed itself.

That moment changed everything about how I thought about investing. It was not just about discipline anymore. It was about physics. About inevitability. About a force so powerful that Albert Einstein (allegedly) called it the eighth wonder of the world.

If you have not experienced that moment yet, this post is going to show you exactly why it is coming, how it works, and why XEQT is the perfect vehicle to make it happen.

1. What Compound Interest Actually Is (Explained Simply)

Most people think of investing as “putting money in and hoping it grows.” That is not wrong, but it misses the most important part: the way it grows.

Here is how compound interest works, in the simplest terms possible:

1. You invest money. Let us say $10,000.
2. Your money earns a return. At 8% annually, that is $800 in Year 1. You now have $10,800.
3. Your return earns a return. In Year 2, you earn 8% on $10,800 – that is $864. Not $800 again. Your returns are earning their own returns.
4. Those returns on returns earn returns. In Year 3, you earn 8% on $11,664 – that is $933. The snowball is getting bigger.
5. This process never stops. Every year, your base gets larger, so the same percentage generates a larger dollar amount.

Think of it like a snowball rolling downhill. At the top, the snowball is small. It picks up a thin layer of snow with each rotation. But as the snowball gets bigger, each rotation adds more snow, because the surface area is larger. After a while, the snowball is growing so fast it barely resembles the tiny ball you pushed off the top.

That is compound interest. Your money makes money. That money makes more money. That money makes even more money. And it never stops.

The critical insight is this: compound interest is not linear. It is exponential. The growth does not happen in equal steps – it accelerates. And the longer you leave it alone, the faster it accelerates.

2. The Math Made Simple: $10,000 at 8% Annually

Let me show you exactly how this plays out with real numbers. We will start with a single $10,000 investment, earning 8% annually, with no additional contributions. Just $10,000, left completely alone.

Look at the annual gain column. In Year 1, your $10,000 earns $800. By Year 10, it is earning $1,599 per year. By Year 20, it is earning $3,453 per year. And by Year 30, your original $10,000 is generating $7,454 in a single year – almost 75% of your original investment, earned in just 12 months.

The gains in Year 30 alone are nearly as large as the original $10,000 you invested. That is the power of compounding. The longer you leave it, the harder your money works.

And here is the part that blows people’s minds: you did absolutely nothing. You invested $10,000 once, never added a penny, and walked away with over $100,000 thirty years later. The extra $90,627 came from nowhere except time and compounding.

3. The Hockey Stick: Why the First $100K Takes the Longest

If you have ever seen a chart of compound growth, you have noticed the shape. It starts nearly flat, curves gently upward, and then – somewhere around the 15 to 20 year mark – it bends sharply upward like a hockey stick.

This is the most important thing to understand about compounding: the early years feel slow. Painfully slow. You are contributing every month, checking your balance, and thinking, “Is this even working?”

It is working. You just cannot see it yet.

Here is what happens when you invest $500 per month at 8% average annual returns:

A few things jump out:

• At year 5, your $30,000 in contributions has grown by only $6,738. Compounding is whispering.
• At year 10, you have crossed $90,000 and your returns ($31,473) have surpassed what you contributed in the last five years.
• At year 15, your total returns ($83,019) are almost equal to your total contributions ($90,000). Compounding is now matching you dollar for dollar.
• At year 20, your returns ($174,510) have overtaken your contributions ($120,000). Your money is now doing more work than you are.
• At year 30, your returns ($565,180) are more than three times your total contributions ($180,000). The snowball is enormous.

This is why people say the first $100K is the hardest. Getting to $100,000 takes roughly 10-11 years of $500 monthly contributions. But the second $100K? That takes only about 4-5 more years. The third $100K takes about 3 years. And the last $100K before you hit $745,000? That takes barely a year and a half.

The curve accelerates because each new dollar in your portfolio is itself compounding. You are not climbing a hill. You are rolling a snowball down one.

4. Why XEQT Is the Perfect Compounding Vehicle

Compounding only works if you have the right vehicle. You need something that grows consistently, costs very little, and does not require constant tinkering. XEQT checks every single box.

Global Diversification Captures Worldwide Growth

XEQT holds over 9,000 stocks across 49 countries. You are not betting on a single company, sector, or country. You are investing in the entire global economy – the collective output of billions of people going to work every day, building businesses, innovating, and creating value.

Over the long term, the global economy has always grown. Wars end. Recessions recover. Pandemics pass. Through all of it, the world economy has expanded, and equity markets have reflected that expansion. XEQT is designed to capture all of it.

0.20% MER Means Almost All Returns Compound for You

This one is huge. XEQT’s management expense ratio is just 0.20% – meaning for every $10,000 invested, you pay just $20 per year. Compare that to a typical Canadian bank mutual fund charging 2.00% or more, where you would pay $200 per year on the same balance.

That difference matters enormously because fees reduce your compounding base. Every dollar lost to fees is a dollar that can never compound. Over decades, the impact is devastating.

Auto-Rebalancing Maintains Optimal Allocation

XEQT automatically rebalances between its underlying funds – Canadian, U.S., international, and emerging market equities. You never need to sell one fund and buy another to stay on target. This matters because rebalancing is not just maintenance; it is a source of additional returns. And XEQT does it for you, silently, in the background.

Dividends Reinvested Amplify Compounding

XEQT pays quarterly dividends, and when you reinvest those dividends (easily done on platforms like Wealthsimple), they buy more units, which generate more dividends, which buy more units. It is compounding within compounding. A virtuous cycle that runs on autopilot.

5. The Fee Drag Table: How MER Silently Destroys Compounding

I mentioned fees briefly above, but this deserves its own section because most Canadians have no idea how much fees are costing them.

Let us compare three scenarios: investing $500 per month for 30 years, with an 8% gross market return, but with different MERs eating into that return.

Read that last row carefully. The investor in the 2.00% mutual fund contributed the exact same amount, invested in the same markets, and held for the same 30 years. But they end up with $191,972 less than the XEQT investor.

That is not a difference in effort, intelligence, or market timing. It is purely the cost of fees compounding against you instead of for you. Nearly $200,000 – evaporated. That is a house. That is a decade of retirement income. That is generational wealth that simply disappeared into a fund company’s pocket.

Every percentage point in fees is compounding stolen from your future. Guard it ruthlessly.

6. The Rule of 72: A Shortcut for Compound Growth

Here is a simple trick that makes compound growth intuitive. It is called the Rule of 72: divide 72 by your expected annual return, and you get the approximate number of years it takes to double your money.

At 8% annual returns, your money doubles roughly every 9 years. So a $10,000 investment becomes:

• $20,000 after 9 years
• $40,000 after 18 years
• $80,000 after 27 years
• $160,000 after 36 years

Each doubling is bigger than the last, because you are doubling a bigger number. The jump from $10,000 to $20,000 is $10,000. The jump from $80,000 to $160,000 is $80,000. Same percentage. Wildly different dollar amount. That is compounding in action.

Now compare this to a high-interest savings account at 2%. At that rate, it takes 36 years to double your money once. In the same 36 years, an 8% equity portfolio would have doubled four times.

This is why time in the market beats a savings account – not by a little, but by orders of magnitude.

7. The Four Enemies of Compounding

Compound interest is powerful, but it is not invincible. There are four forces that can undermine or destroy your compounding engine. Knowing what they are is essential to protecting your wealth.

Enemy #1: Interruption

Every time you withdraw money from your portfolio, you are not just losing that money – you are losing everything that money would have compounded into. Pulling $5,000 out of a portfolio earning 8% does not cost you $5,000. Over 30 years, it costs you roughly $50,000 in lost growth.

Keep an emergency fund separate from your investments. Never raid your compounding engine.

Enemy #2: Fees

We covered this above, but it bears repeating: fees are compounding in reverse. Every dollar paid in management fees is a dollar that can never earn returns, which means those returns can never earn their own returns. A 2% annual fee does not cost you 2%. Over 30 years, it costs you roughly 35-40% of your total portfolio value.

XEQT’s 0.20% MER is one of the lowest available in Canada. Protect your compounding base.

Enemy #3: Inflation

Inflation is the silent tax on your wealth. If your portfolio earns 8% but inflation is 3%, your real return is only 5%. The good news: equities have historically outpaced inflation over the long term. XEQT, with its global diversification across 49 countries, owns companies that can raise prices along with inflation, delivering strong real returns over 20- to 30-year horizons.

Enemy #4: Waiting

This is the biggest enemy of all, and it is the most insidious because it does not feel like it is costing you anything. Waiting one more year feels harmless. What is one year?

It is a lot. Every year you delay is not a flat cost – it is an exponential one. Because compounding is exponential, the earliest years of growth are the most valuable. A dollar invested at age 25 is worth dramatically more than a dollar invested at age 35, because it has 10 extra years of compounding.

The cost of waiting is not measured in years. It is measured in hundreds of thousands of dollars.

8. The Twin Investor Scenario: The Most Powerful Illustration of Compounding

This is the story that convinced me to stop waiting and start investing immediately. It is the single most compelling demonstration of compound interest I have ever seen.

Meet two investors: Aisha and Ben.

Aisha starts investing $500 per month at age 25. She invests faithfully for 10 years, then stops completely at age 35. She never invests another dollar. Her total contributions: $60,000 over 10 years.

Ben waits until age 35 to start. He invests $500 per month and does not stop until age 65. He invests for 30 years straight. His total contributions: $180,000 over 30 years.

Both earn 8% average annual returns. Who has more money at age 65?

Read those numbers again.

Aisha invested one-third of the money Ben did. She stopped investing 30 years before retirement. And she still ended up with $148,524 more than Ben.

How is this possible? Because Aisha gave her money 10 extra years to compound at the beginning, when compounding is building the foundation. By the time she stopped investing at 35, she had roughly $91,473. That $91,473 then compounded untouched for 30 more years, growing to nearly $894,000.

Ben started with nothing at 35 and had to build from scratch. Even though he invested three times as much money and invested for three times as long, he could not overcome Aisha’s 10-year head start.

This is the most important lesson in all of personal finance: time is the single most valuable ingredient in building wealth. Not income. Not investment skill. Not market timing. Time.

If you are in your 20s reading this, you have the most valuable asset any investor can have. Do not waste it.

If you are in your 30s, 40s, or beyond, the second-best time to start is today. The math still works – Ben still turned $180,000 into $745,180. The snowball still rolls. You just want to push it down the hill as soon as humanly possible.

9. Compounding Across Your Lifetime

Suppose you start investing $500 per month at age 25, earn 8% average annual returns, and never stop.

At 30, your portfolio barely exceeds your contributions. By 45, compounding has multiplied your money 2.5 times. By 55, you are sitting on $745,000 from just $180,000 in contributions. And at 65, you have contributed $240,000 over your lifetime, but your portfolio is worth $1.74 million – compounding delivered over $1.5 million in pure growth, more than 7 times your contributions.

This is what people mean when they say “make your money work for you.” In the early years, you do the heavy lifting. By the end, your money is doing seven times as much work as you are.

10. How to Harness Compound Interest Starting Today

You do not need a high income. You do not need to understand options trading or cryptocurrency. You do not need to time the market. You just need to do four things:

Start Now, Even If It Is Small

Even $50 per month is enough to get the compounding engine running. $50 per month at 8% for 30 years grows to over $74,000. That is $74,000 from $18,000 in contributions. The amount matters far less than the start date. Every month you wait costs you more than you think.

Automate It

Set up automatic recurring purchases of XEQT on Wealthsimple. Pick a day. Pick an amount. And then forget about it. Automation removes the two biggest threats to your compounding: forgetting and talking yourself out of it.

The best investors I know do not spend time analyzing charts. They set up automatic contributions and then go live their lives. The money flows in, XEQT buys happen, and compounding does its thing silently in the background.

Do Not Interrupt It

This is the hardest part. Markets will crash. Your portfolio will drop 20%, maybe 30%, maybe more. You will be tempted to sell. Every fibre of your being will scream at you to stop the bleeding.

Do not listen.

Every major market decline in history has been followed by a recovery. The investors who came out wealthy on the other side were the ones who stayed invested. Pulling out during a crash is not just selling low – it is resetting your compounding clock to zero.

Keep Fees Low

Choose XEQT and its 0.20% MER. Avoid bank mutual funds with MERs of 2% or more. As we showed above, the difference over 30 years is nearly $200,000. That is not a small optimization. That is a life-changing amount of money.

The Bottom Line

Compound interest is not complicated. It is not a secret. It is not reserved for the wealthy or the financially sophisticated. It is a mathematical force that is available to every single person who is willing to invest money, leave it alone, and give it time.

The formula is almost absurdly simple:

1. Open a Wealthsimple account
2. Buy XEQT
3. Set up automatic contributions
4. Wait

That is it. No stock picking. No market timing. No expensive advisors. Just consistent, automated investing in a low-cost, globally diversified ETF, and the patience to let compounding do what it has always done.

The snowball is waiting for you to push it. And the hill stretches out for decades. The only question is whether you start today, or whether you look back in 10 years and wish you had.

I know which one I would choose. I have already seen the month where my portfolio earned more than I put in. I have already felt the shift from “I am saving” to “my money is working for me.” And I can tell you this: once you feel it, you will never want to stop.

Start now. Start small if you have to. But start.
