XEQT Buying Frequency: Weekly vs Biweekly vs Monthly — Does It Matter?

I used to agonize over this exact question. Back when I first started investing in XEQT, I spent an entire weekend building a spreadsheet to compare weekly, biweekly, and monthly purchases. I ran scenarios. I pulled historical data. I even posted on Reddit asking strangers which frequency was “optimal.”

After all that research, all those numbers, and all those opinions from anonymous internet people, I arrived at a conclusion that I wish someone had just told me from the start:

The frequency barely matters. What matters is that you invest consistently, period.

But I know that answer alone probably won’t satisfy you – it wouldn’t have satisfied 2020 me either. So let’s dig into the actual math, the real trade-offs, and the practical considerations that will help you pick the right buying frequency for your situation. By the end of this guide, you’ll be able to stop overthinking and start (or keep) investing.

1. The Three Main Frequencies Explained

When it comes to buying XEQT on a recurring schedule, most Canadian investors land on one of three frequencies. Let’s break down each one before we get into the numbers.

Weekly

You invest a fixed amount every week – for example, $125 per week if your monthly budget is $500.

Pros:

• Maximum price smoothing – you buy at 52 different price points per year
• Money gets into the market quickly; cash never sits idle for long
• Psychologically satisfying during volatile markets (you catch every dip)

Cons:

• More transactions to track for record-keeping
• Can feel like a lot of mental overhead, even if automated
• Slightly more complex to align with pay schedules

Biweekly (Every Two Weeks)

You invest a fixed amount every two weeks – typically aligned with a biweekly paycheque. For example, $250 every two weeks.

Pros:

• Naturally aligns with most Canadian pay schedules (about 60% of salaried Canadians are paid biweekly)
• 26 purchase points per year – a solid balance between smoothing and simplicity
• The “bonus” effect: biweekly investing means two months per year have three contributions instead of two

Cons:

• Doesn’t line up neatly with monthly budgeting
• Slightly harder to calculate annual totals at a glance

Monthly

You invest a fixed amount once per month – for example, $500 on the 1st or 15th of every month.

Pros:

• Dead simple to budget and track
• Clean records for tax purposes
• Aligns naturally with monthly expenses, rent, and other bills
• Minimum mental overhead

Cons:

• Cash may sit uninvested for up to a month
• Only 12 price points per year (less smoothing)
• If your one purchase date hits a local high, you might feel unlucky (even though it doesn’t actually matter)

Here’s a quick side-by-side:

2. The Math: How Much Does Frequency Actually Matter?

Here’s the part most people are really looking for. Let’s run the numbers on $500 per month invested into XEQT across all three frequencies, assuming an average annual return of 8% (a reasonable long-term expectation for a globally diversified equity ETF).

For the weekly scenario, that’s roughly $115.38 per week ($6,000/52). For biweekly, it’s $230.77 every two weeks ($6,000/26). For monthly, it’s $500 on the first of each month.

The key difference between frequencies is how quickly your money gets deployed. Weekly investing puts your cash to work an average of about 2 weeks sooner than monthly investing. Over time, that earlier deployment earns returns.

Assumptions: 8% annualized return, $6,000 invested per year across all scenarios. Figures are approximate and rounded to illustrate the scale of the difference.

Read that last column again. After 30 years of investing, the difference between buying XEQT weekly versus monthly is roughly $4,000. On a portfolio worth over $740,000, that’s about half a percent.

To put it another way: the frequency decision is worth approximately $133 per year over a 30-year investing career. That’s less than the cost of one dinner out per month.

Here’s the thing – $4,000 is not nothing. But compare it to the impact of increasing your monthly contribution by even $50 (which would add roughly $75,000 over 30 years at 8%), and you see just how far down the priority list buying frequency falls.

3. Why Frequency Matters Less Than You Think

The math above hints at a bigger truth that I think every Canadian investor needs to internalize: time in the market beats timing the market, and it also beats optimizing the market.

Here’s why the frequency gap is so small:

Markets trend upward, but slowly on any given day

XEQT’s long-term returns work out to roughly 0.03% per trading day. The difference between deploying cash on Day 1 versus Day 14 of a month is measured in fractions of a fraction of a percent. Over any single month, the expected gain from earlier investing is about $1-2 on a $500 purchase. That’s not a typo.

Price smoothing has diminishing returns

Going from 1 purchase per year to 12 (monthly) makes a meaningful difference in your average purchase price. Going from 12 to 26 (biweekly) helps a little. Going from 26 to 52 (weekly) helps even less. The incremental benefit shrinks rapidly because XEQT’s price rarely moves dramatically within any given month.

The biggest risk is not investing at all

Here’s a scenario that plays out all the time: someone decides they want to invest weekly instead of monthly. They set up weekly auto-invest, but their bank balance dips one week and the purchase fails. They feel annoyed. The next week, they’re busy and forget to fix it. Before they know it, three weeks have gone by and they haven’t invested at all.

A monthly purchase that actually happens beats a weekly purchase schedule that you don’t maintain. Consistency is worth far more than frequency.

If you’re interested in the broader philosophy behind this, my guide on dollar-cost averaging into XEQT covers the behavioral side in more depth.

4. When Weekly Actually Makes Sense

Even though I’ve just told you frequency barely matters, there are a few situations where weekly investing has genuine advantages. I want to be fair about this.

You have a volatile income

If you’re a freelancer, gig worker, or commission-based salesperson, your income might arrive in irregular chunks. Investing a smaller amount weekly can be easier to manage than setting aside a large monthly lump sum.

You’re psychologically wired for frequent action

Some people feel better when they invest more often. If buying XEQT weekly gives you a sense of progress and momentum – and that keeps you investing consistently – the psychological benefit is real and worth the minor extra complexity.

Markets are highly volatile

During sharp market swings (think early 2020 or late 2022), weekly purchases let you capture more distinct price points. If XEQT drops 8% in a week and recovers, a weekly buyer gets to buy at that dip. A monthly buyer might miss it entirely. This cuts both ways – you also buy at more local highs – but it can feel better knowing you caught a dip, and feelings matter when they keep you invested.

You’re investing small amounts

If your monthly budget is small ($100-200), weekly chunks of $25-50 keep the investing habit top of mind. For beginners, a weekly ritual of “I invested today” builds powerful momentum. See how to start investing $100 per month in XEQT for more.

5. When Monthly Is Perfectly Fine

And here’s the other side: for most people, monthly investing works great. Here’s when it’s the right call.

Your pay schedule is monthly

If you get paid once a month, investing monthly is the obvious choice. Set up auto-invest for the day after payday and you’re done. Trying to convert a monthly paycheque into weekly investments just adds unnecessary cash flow management.

You value simplicity above all else

One purchase per month means 12 transactions per year to review at tax time. One line item per month in your budget. One date to remember. For investors who want minimal mental overhead, monthly is hard to beat.

You’re investing in a non-registered account

Fewer transactions means simpler record-keeping for your adjusted cost base (ACB). Every purchase creates a new ACB calculation, so 12 per year is much easier to manage than 52.

You’re already investing consistently

If you’ve been investing monthly for years and you’re happy with your system, don’t fix what isn’t broken. Switching to weekly to chase an extra 0.5% over 30 years is over-optimization. Your energy is better spent increasing your savings rate or optimizing your tax strategy.

6. How to Automate Each Frequency on Wealthsimple

One of the reasons I recommend Wealthsimple for XEQT investing is that their auto-invest feature supports all three frequencies natively. No workarounds needed.

Here’s how to set up each one:

The setup (same for all frequencies)

1. Open the Wealthsimple app and navigate to your account (TFSA, RRSP, FHSA, etc.)
2. Search for XEQT and tap on it
3. Tap “Recurring buy” (or “Auto-invest” depending on your app version)
4. Set your amount (e.g., $125/week, $250/biweekly, or $500/month)
5. Select your frequency: Weekly, Biweekly, or Monthly
6. Choose your start date – align it with your payday for best results
7. Confirm and you’re done

A few important tips for all frequencies:

• Make sure your bank account has funds. Wealthsimple pulls from your linked bank account. If there’s insufficient funds, the purchase fails and you miss a contribution.
• Fractional shares are supported. Your full amount gets invested – no leftover cash sitting idle. If XEQT trades at $31.50 and you invest $125, you’ll get exactly $125 worth of XEQT.
• No commissions. Buying XEQT on Wealthsimple is free, regardless of how frequently you buy. This is a big deal – on platforms that charge per trade, weekly buying would cost $520/year in commissions (52 trades x $10). On Wealthsimple, it costs $0.

7. The Real Answer: Match Your Pay Schedule

After all the math, all the tables, and all the scenarios, here’s the real answer. It’s not exciting, but it’s true:

Your optimal XEQT buying frequency is whatever matches your pay schedule.

• Paid biweekly? Invest biweekly. Set up auto-invest for your payday (or the day after).
• Paid semi-monthly (1st and 15th)? Invest twice a month, on each payday.
• Paid monthly? Invest monthly. Pick a date and automate it.
• Paid weekly? Invest weekly.
• Irregular income? Invest whenever money comes in, or set a weekly minimum and top up when you can.

Why is pay schedule the right framework? Three reasons:

1. Cash flow alignment. When your investing happens on payday, the money never sits in your chequing account long enough for you to spend it. This is the “pay yourself first” principle in action.

2. Consistency is automatic. You don’t need to remember to invest, transfer funds between accounts, or check whether this is a “buy week.” It just happens.

3. Behavioral simplicity. Every additional decision you add to your investing process is a chance to procrastinate, second-guess, or skip. Matching your pay schedule removes one more decision.

I get paid biweekly, so I invest biweekly. If I got paid monthly, I’d invest monthly without losing a minute of sleep over it. The difference is genuinely not worth your mental energy.

8. Common Mistakes People Make with Buying Frequency

I’ve seen all of these in online forums, in conversations with friends, and – I’ll be honest – in my own early investing days. Here are the traps to avoid.

Mistake 1: Changing frequency constantly

Some people start monthly, switch to weekly because a blog post convinced them it’s better, then switch back to monthly because tracking 52 transactions felt overwhelming. Every switch disrupts your routine and introduces a gap where you might not invest at all.

Pick a frequency and stick with it for at least a year. If you want to adjust after that, fine. But give your system time to work.

Mistake 2: Choosing weekly when you can’t fund it weekly

If your bank balance fluctuates and weekly auto-invest purchases occasionally fail because there’s not enough money in your account, you’re worse off than if you’d just invested monthly. A failed auto-invest is a missed contribution. A few missed contributions, and you’ve lost more than the theoretical advantage of weekly investing.

Mistake 3: Obsessing over frequency instead of amount

I cannot stress this enough: how much you invest matters 10-100x more than how often you invest. Finding a way to bump your monthly contribution from $500 to $600 will have a dramatically larger impact on your 30-year portfolio than switching from monthly to weekly investing.

If you’re spending time optimizing frequency, redirect that energy toward increasing your savings rate. Your future self will thank you.

Mistake 4: Manually buying instead of automating

Some investors set up a weekly schedule but insist on placing each trade manually, “just to check the price first.” This defeats the entire purpose of systematic investing. The moment you check the price before buying, you’ve introduced a psychological hurdle. If the price is up, you might wait for a dip. If it’s down, you might wait for it to fall further. Before you know it, you’re timing the market – the one thing dollar-cost averaging is designed to prevent.

Automate it. Stop checking. The price today genuinely does not matter for a 20-year investment.

Mistake 5: Splitting investments across too many accounts and frequencies

I’ve seen people set up weekly buys in their TFSA, biweekly buys in their RRSP, and monthly buys in their FHSA – all at different amounts. This creates an administrative headache that makes investing feel like a second job. Keep it simple: use the same frequency across all your accounts, ideally aligned to a single trigger (like payday).

9. What About Biweekly’s Hidden Advantage?

There’s one nuance about biweekly investing that I want to highlight because it’s often overlooked.

If you invest $250 biweekly, you’re not investing the same annual total as someone investing $500 monthly. Biweekly means 26 pay periods per year, not 24. So your annual total is $6,500, not $6,000.

That extra $500 per year – two “bonus” contributions – adds up significantly over time:

That’s a $62,600 difference – but it has almost nothing to do with the frequency of investing and everything to do with investing more money. If you bumped your monthly contribution from $500 to $542 (to match the biweekly annual total), you’d get essentially the same result.

The lesson: if you’re paid biweekly, investing biweekly is great – partly because of the two bonus contributions you might not even notice. But don’t confuse “biweekly is better” with “more frequent is better.” It’s really just “more money is better.”

10. The Final Verdict

Let me give you the actionable summary, because I know you came here looking for a definitive answer.

If you take away one thing from this article, let it be this:

The best buying frequency for XEQT is the one that aligns with your pay schedule and that you will maintain for decades without thinking about it.

Here’s your decision framework in four steps:

1. Determine your pay frequency. Biweekly? Monthly? Semi-monthly? That’s your answer.
2. Set up auto-invest on Wealthsimple (or your preferred commission-free broker) to match that pay schedule. See my Wealthsimple automation guide for the step-by-step walkthrough.
3. Invest the maximum amount you can sustain. This matters 10-100x more than frequency.
4. Stop thinking about frequency. Seriously. Close the spreadsheet. Leave the Reddit thread. Go enjoy your life. The money is working for you now.

The truth is, I’ve been investing in XEQT on a biweekly schedule for years – not because I ran the numbers and determined biweekly was mathematically optimal (the difference is laughably small), but because I get paid biweekly. It takes zero thought. The money comes in, the auto-invest fires, XEQT gets bought, and I go about my day.

That’s the whole game. Not which day. Not which week. Not whether to split your contribution into four pieces or keep it as one. Just consistent, automated, boring purchases of a globally diversified ETF, month after month, year after year, until you look up one day and realize you’ve built something substantial.

So pick your frequency. Automate it. And go live your life.
