There is a sentence that has quietly cost Canadians more money than almost any bad investment decision, any market crash, or any financial mistake they have ever made.

It is not dramatic. It doesn't arrive in a moment of obvious recklessness. It comes softly, reasonably, and often with genuinely good intentions.

The sentence is: "I'll start next year."

Next year, when the credit card is paid off. Next year, when the job situation is more stable. Next year, when there is a little more breathing room. Next year, once the kids are in school, once the mortgage is sorted, once life settles down enough to think clearly about retirement.

Next year is not a decision. It feels like one, because it comes with the comfort of intention. But financially, it functions exactly like the opposite of a decision — it is a choice to let time pass without putting it to work. And time, in the mathematics of compound growth, is the single most valuable resource available to any investor.

This post is not about making you feel guilty. It is about showing you, with real numbers, what one year of delay actually costs. Because most people who say "next year" have genuinely never seen the calculation. And once you see it, it is very difficult to unsee.

First, understand what compound growth actually does

Compound growth is the process by which returns generate their own returns. You invest $10,000. It grows by 8% in year one — now you have $10,800. In year two, that 8% applies to $10,800, not to your original $10,000. You earn $864 rather than $800. The year after that, 8% applies to $11,664. And so on.

In the early years, this feels almost trivially small. The difference between $10,000 and $10,800 is not life-changing. But compound growth is not a short-term phenomenon. It is a long-term one, and its power increases dramatically with time — not linearly, but exponentially. The longer the runway, the more the curve bends upward.

This is why the timing of when you start matters so enormously — and why a one-year delay, which feels like almost nothing, has consequences that ripple forward across decades.

The numbers — what one year actually costs

Let's run the calculation that most people have never seen.

We will use a moderate, realistic assumption: an average annual return of 8%, which reflects a long-term diversified portfolio that includes both equity and fixed income — the kind of balanced, managed portfolio that Terces Finance builds for clients. This is conservative enough to be credible and consistent with long-term historical averages for diversified Canadian and global portfolios.

Scenario: A 30-year-old Canadian investing $500 per month

Starting at 30, investing until 65 — 35 years:

• Total contributions: $210,000
• Portfolio value at 65: $1,089,760

Starting at 31, investing until 65 — 34 years:

• Total contributions: $204,000
• Portfolio value at 65: $998,460

The cost of that one year: $91,300.

One year of waiting — contributing $6,000 less in total — costs over $91,000 at retirement. That is not a typo. That is compound growth working against you rather than for you. The lost year near the beginning of a long investment timeline costs more than fifteen times the actual contributions missed.

What if you wait five years?

Five years feels more relatable — it's the length of a typical "I'll figure it out eventually" window. Let's see what that looks like.

Starting at 30, investing until 65 — 35 years:

• Total contributions: $210,000
• Portfolio value at 65: $1,089,760

Starting at 35, investing until 65 — 30 years:

• Total contributions: $180,000
• Portfolio value at 65: $734,075

The cost of five years: $355,685.

Five years of delay costs over $355,000 — on contributions that were only $30,000 less in total. The extra $325,000 gap is pure compound growth that was never given the opportunity to exist. It is not money that was spent or lost in a market crash. It is money that was simply never created because the time it needed was not given to it.

What if you wait ten years?

Starting at 30, investing until 65 — 35 years:

• Portfolio value at 65: $1,089,760

Starting at 40, investing until 65 — 25 years:

• Total contributions: $150,000
• Portfolio value at 65: $478,959

The cost of ten years: $610,801.

More than half a million dollars. On a difference in total contributions of only $60,000.

This is the counterintuitive truth that compound growth produces: the timing of contributions is worth vastly more than the amount of contributions. Starting 10 years earlier and contributing $60,000 more creates a $610,000 difference. No investment product, no market timing strategy, and no financial advisor's skill can recreate that gap once it has been allowed to open.

The "I'll catch up later" myth

A natural response to these numbers is: "Fine, but if I wait and then contribute more each month, surely I can close the gap?"

Let's test that.

Our 40-year-old who starts investing at 40 has a target of $1,089,760 — what the 30-year-old achieves with $500 per month. How much would they need to contribute monthly to reach the same outcome in 25 years at 8%?

The answer is approximately $966 per month.

To replicate the outcome of starting at 30 with $500 a month, the 40-year-old needs to invest $966 a month — nearly double — for the remaining 25 years. The total contributions required: $289,800 versus $210,000. The 40-year-old contributes $79,800 more and still only arrives at the same destination, having worked harder to get there.

This is what "catching up later" actually looks like. It is not impossible — but it is significantly more demanding than simply starting when you first thought about it.

The tax-free multiplier: why this is even more important inside a TFSA

Everything above assumes a taxable investment account, where returns are subject to annual income tax. The real picture for Canadian investors is more compelling, because the TFSA removes tax from the equation entirely.

Inside a TFSA, that 8% return is not reduced by taxes year over year. The compound curve bends upward more steeply, because nothing is being taken out of the growth engine along the way.

The principle is the same, but the penalty for delay is amplified. Every year that $500 per month sits in a low-interest savings account instead of a TFSA-sheltered portfolio is a year of tax-free compound growth that can never be recovered.

And the TFSA has a second dimension: contribution room. Every year that passes with unused TFSA room is a year of permanently foregone tax-free space. The room accumulates, but the tax-free growth that could have happened inside that room does not. It is quietly lost, year by year, with no announcement and no statement to show for it.

The three "reasonable reasons" that tend to cost the most

In our experience working with Canadian clients, three justifications come up most often when explaining why investing has been delayed. Each one is genuinely understandable. Each one is also genuinely expensive.

"I want to pay off my debt first."

This one depends entirely on the type of debt. High-interest revolving debt — credit cards, certain lines of credit, absolutely warrants aggressive repayment, because a guaranteed 19–24% return on debt repayment beats almost any investment return available. But low-interest debt — a mortgage, a student loan at 4–6% — does not. Waiting to invest until a mortgage is paid off often means waiting until your 50s, surrendering two full decades of compound growth in exchange for the psychological comfort of being debt-free before investing.

A structured financial plan can hold both: a debt repayment strategy and a simultaneous investment strategy, calibrated to the interest rates involved.

"I'm waiting until I have more to invest."

The minimum amount required to make investing worthwhile is lower than most people assume, sometimes significantly lower. And the mathematics are unambiguous: $200 per month started today outperforms $400 per month started in three years, even though the three-year starter contributes more in absolute terms. The amount matters less than the timing. Starting with whatever is available now is almost always the better decision.

"I need to understand it better before I start."

This is the one that has the most sympathetic logic and the highest real-world cost, because financial complexity is genuinely real and the impulse to understand before committing is genuinely responsible. But the trap is that "understanding it better" becomes a moving target, there is always more to learn, and complexity can be used unconsciously to indefinitely justify inaction.

The practical answer is that understanding does not need to precede starting. It can develop alongside it. A 30-minute conversation with a financial advisor — one that begins with your goals and your situation, not with products — can provide enough clarity to make a first move. The rest of the education can happen while your money is already working.

What this looks like the other way

It is worth spending a moment with the optimistic version of these numbers, because the same mathematics that make delay so costly make early action so powerful.

Scenario: Starting at 25, investing $300 per month at 8% until 65

• Total contributions: $144,000
• Portfolio value at 65: $1,026,853

Over a million dollars from $300 a month — by doing nothing more than starting five years earlier and contributing $200 per month less than the 30-year-old in our original example.

This is not magic. It is not a market prediction or a guaranteed outcome. It is simply what happens when you give compound growth a long enough runway and stay out of its way.

The only question that matters

After seeing these numbers, the natural response is to wonder: what would my situation look like?

That is exactly the right question. And it is one that has a specific, calculable answer for your income, your timeline, your current savings, and your retirement goals. It is not a theoretical exercise — it is a 20-minute conversation.

Because while the mathematics above are general, your situation is specific. You have a specific amount you can realistically contribute, a specific debt picture, a specific risk tolerance, and a specific version of what financial security looks like for you. The right strategy is the one built around those specifics — not around a generic scenario with round numbers.

The one thing the generic scenario and your specific scenario have in common is this: the best time to start was at whatever age you first thought about it. The second-best time is now.

Not next year. Not once things settle down. Not after the next raise, the next milestone, the next version of life that feels stable enough to think about the future.

Now — with whatever is available, however imperfect, however small.

Because in the mathematics of compound growth, now beats next year every single time.
