Two Canadian investors open their investment accounts on the same morning.
Aman has received a $100,000 windfall. He invests the entire amount in XEQT immediately and never contributes another dollar.
Maya does not have $100,000. Instead, she automatically invests $1,000 from her income each month—and plans to continue for 30 years.
Aman begins with an enormous head start. Maya begins with a repeatable contribution plan.
Who eventually builds the larger portfolio?
Quick Answer
Assuming an average annual return of 6% after fund fees, with all distributions reinvested:
| Time invested | $100,000 invested once | $1,000 invested monthly |
|---|---|---|
| 10 years | $179,085 | $162,473 |
| 20 years | $320,714 | $453,439 |
| 30 years | $574,349 | $974,513 |
The $100,000 lump sum remains ahead for approximately 11.5 years. After that, the continuing monthly contributions overtake it.
After 30 years, Maya finishes with approximately $400,164 more. However, she contributes a total of $360,000, compared with Aman’s original $100,000.
Monthly investing does not earn a better investment return in this example. It produces a larger final balance because substantially more money is contributed over time.
Key Takeaways
- Investing $100,000 immediately gives the entire amount more time to compound.
- The lump-sum portfolio remains ahead for approximately 11.5 years.
- Investing $1,000 monthly creates the larger 30-year portfolio because contributions eventually total $360,000.
- XEQT is an all-equity ETF and can experience significant market declines.
- The comparison demonstrates two different advantages: investing available capital early and contributing consistently over time.
The First Market Decline
The first major decline would feel different for each investor.
Aman watches his entire $100,000 move with the market. A 10% decline could temporarily reduce his investment to approximately $90,000. A 30% decline could take it near $70,000.
Nothing about that loss would feel theoretical.
Maya’s account is initially much smaller. Her existing investment also falls when markets decline, but each new $1,000 contribution can purchase more ETF units at lower prices.
Aman may also acquire additional units at lower prices when distributions are reinvested. However, Maya is adding considerably more new capital through her monthly contributions.
Aman needs the confidence to remain invested. Maya needs both the discipline and financial capacity to continue contributing.
Those behavioural challenges can determine whether either strategy survives long enough for compounding to work.
What Is XEQT?
XEQT is the iShares Core Equity ETF Portfolio. BlackRock designed it to provide long-term capital growth through exposure to Canadian, American, international and emerging-market equities.
According to BlackRock’s official XEQT information, the fund had a management fee of 0.17% and a management expense ratio of 0.20% as of July 2026.
XEQT offers broad diversification, but diversification does not prevent losses. The fund targets a 100% equity allocation and may experience substantial declines during bear markets.

After 10 Years: The Lump Sum Leads
At an assumed 6% annual return, Aman’s $100,000 grows to approximately $179,085 after 10 years.
Maya contributes $120,000 during the same period, but her portfolio reaches approximately $162,473.
Despite contributing $20,000 more, Maya remains about $16,612 behind.
The difference comes from time in the market. Aman’s entire $100,000 began compounding on the first day, while Maya gradually added money throughout the decade. Her most recent contributions had little time to grow before the comparison date.
After 20 Years: Monthly Contributions Move Ahead
By year 20, Aman’s portfolio reaches approximately $320,714.
Maya has contributed $240,000, and her portfolio reaches approximately $453,439. She is now roughly $132,725 ahead.
Her individual dollars did not earn a higher assumed return. She overtook Aman because she continued adding money after Aman stopped contributing.
After 30 Years: Nearly $1 Million
After three decades:
- Aman contributes $100,000 and finishes with approximately $574,349.
- Maya contributes $360,000 and finishes with approximately $974,513.
Maya is approaching $1 million. Aman has still transformed one large investment into more than five times its original value without making another contribution.
The results represent two different wealth-building paths. Aman demonstrates the value of investing available money early. Maya demonstrates what can happen when a monthly contribution is repeated 360 times.
What If XEQT Returns Less—or More?
No one knows what XEQT will return over the next 30 years. Different assumed returns produce dramatically different outcomes.
Projected Value After 30 Years
| Assumed annual return | $100,000 invested once | $1,000 invested monthly |
|---|---|---|
| 4% | $324,340 | $685,271 |
| 6% | $574,349 | $974,513 |
| 8% | $1,006,266 | $1,408,551 |
These figures are mathematical illustrations—not forecasts.
The calculations assume:
- The stated annual return is received after fund fees.
- Distributions are fully reinvested.
- Monthly investments are made at the end of each month.
- No money is withdrawn.
- Taxes, inflation and brokerage costs are excluded.
Actual returns would not arrive in a smooth line. Strong years, market crashes and extended recovery periods could all affect the investing experience and final result.
The sequence of returns may also affect the monthly investor differently because contributions are made at changing market prices.
Does Lump-Sum Investing Usually Win?
If an investor already has the entire $100,000, the more appropriate comparison is not $100,000 today versus $1,000 monthly for 30 years.
It is investing $100,000 today versus gradually investing that same $100,000.
Vanguard examined historical and simulated market data and found that lump-sum investing outperformed common cost-averaging strategies approximately two-thirds of the time.
The reason is straightforward: money invested immediately receives more time in the market. Holding part of an available lump sum in cash creates an opportunity cost when markets rise.
However, historical results cannot guarantee the next outcome.
Gradual investing may feel more manageable for someone who fears investing immediately before a major decline. A mathematically efficient strategy offers little practical value if the investor panics, sells and permanently locks in a loss.
What About a TFSA or RRSP?
The type of account holding XEQT could materially affect an investor’s after-tax result.
Investment growth and withdrawals are generally tax-free inside a TFSA. However, foreign withholding taxes may still apply to some income received by XEQT’s underlying holdings and may not be recoverable inside the account.
RRSP contributions may generate a tax deduction, while withdrawals are generally taxable. In a non-registered account, distributions and realized capital gains may create tax obligations.
The most suitable account depends on factors including income, available contribution room, time horizon and expected retirement tax rate.
Account selection does not change XEQT’s underlying market performance, but it can change how much of the return the investor ultimately keeps.
TwikUp Insight
This is not an equal-dollar comparison.
Aman contributes $100,000. Maya contributes $360,000 over 30 years. The purpose of the example is to show how a large initial investment compares with a smaller but continuing contribution plan.
For someone who already has a lump sum and can also afford monthly contributions, the strongest approach may combine both strategies:
- Keep an appropriate emergency fund outside the stock market.
- Invest long-term money according to personal risk tolerance.
- Establish automatic monthly contributions.
- Reinvest distributions.
- Continue the plan through both rising and falling markets.
This allows existing money to begin compounding while future income continues building the portfolio.

Final Verdict
At an assumed 6% annual return, $100,000 invested immediately produces the larger portfolio during the first decade.
The investor contributing $1,000 each month overtakes the untouched lump sum after approximately 11.5 years. After 30 years, the monthly portfolio reaches approximately $974,513, compared with $574,349 for the lump-sum portfolio.
Maya finishes with more because she contributes $360,000 over the full period—not because monthly investing generates a higher return.
Aman’s original dollars produce substantially more growth per dollar contributed because they remain invested for the entire 30 years. Maya builds the larger portfolio by combining compounding with decades of additional contributions.
One strategy demonstrates the power of investing available capital early. The other demonstrates the power of continuously adding new capital.
