Do you know how your portfolio is actually doing?

For years, I built spreadsheets to answer a question my brokerage couldn’t: how is my portfolio actually doing? Not just the dollar amount on the screen, but the real return, accounting for the money I’d added along the way, the dividends, the fees, the timing of everything. VLOOKUPs, IF statements, formulas referencing formulas. I was proud of the system, but I also knew it was fragile, and I knew most people would never build one.

The problem is that without that kind of work, you’re left with whatever number your brokerage app shows you. And that number is almost never what you think it is. It doesn’t separate your contributions from your gains. It doesn’t tell you if you’re beating or trailing the market. It just shows a dollar figure that goes up or down, and you take it at face value. Why wouldn’t you? It’s presented like a final answer.

The number your brokerage shows you

Most brokerage apps show you a dollar amount. Your account is worth $56,000. It was worth $52,000 last time you checked. So you’re up $4,000. Great.

But that number includes everything. Your investment returns, yes. But also any money you deposited since your last check. Any dividends that landed in your account. Any transfers between accounts. It’s all mashed into one figure.

Some platforms show a percentage alongside the dollar change, but the calculation behind it varies. Some show a simple gain: current value minus total deposits. Others show a time-weighted return, which strips out the effect of contributions. Some show something in between. Most don’t explain which one they’re using.

So when your app says “up 12%,” it might mean your investments grew by 12%. Or it might mean your account balance increased by 12%, partly because you added money. Those are very different things, and the app treats them the same.

Contributions vs. returns

This is the confusion I see more than any other.

Say you started the year with $50,000 in your TFSA. Throughout the year, you deposited another $3,000. By December, your account shows $56,000. You look at that and think: I started with $50,000, now I have $56,000, that’s a 12% return.

But $3,000 of that increase was money you put in. Your actual investment return is closer to $3,000 on a base that averaged somewhere around $51,500 (since the deposits came in gradually). That’s roughly 5.8%. Not 12%.

The difference between “my account grew by 12%” and “my investments returned 5.8%” is enormous. One sounds like a great year. The other is fine but unremarkable. And unless you separate contributions from returns, you genuinely can’t tell which one happened.

This gets even muddier if you’re making regular contributions, which most people are. Every paycheque, a bit goes into the RRSP or TFSA. The account balance climbs steadily, and it looks like your investments are doing well. Some of that is growth. Some of it is just your own money showing up. Without doing the math or having a tool that does it for you, there’s no way to untangle the two by looking at your brokerage screen.

I wrote about this in more detail in why investment returns are so confusing. The short version: even the word “return” means different things depending on how it’s calculated, and most platforms don’t tell you which version they’re showing.

What would have happened if you’d just bought one ETF?

This is the question that makes everything click, and too many investors never ask it.

Say your portfolio returned 8% last year. That sounds pretty good. But if a single all-in-one ETF like XEQT returned 14% over the same period, your 8% means you underperformed the simplest possible strategy by 6 percentage points. You did a lot of work, picked a lot of stocks, and ended up worse off than if you’d bought one thing and gone for a walk.

That’s not meant to be discouraging. It’s meant to be clarifying. A return number means nothing without context. 8% could be exceptional or disappointing depending on what the market did, how much risk you took, and what the alternatives were.

This is what a benchmark gives you. Not a target you have to beat. Just a reference point. A way to answer the question: compared to what?

Most brokerages don’t show you this comparison. They show your return in isolation, which makes it impossible to evaluate. It’s like being told your car gets 8 litres per 100 km with no idea whether that’s good or bad for your type of vehicle. The number alone doesn’t help.

This isn’t financial advice, and past performance doesn’t predict future results. But knowing how your portfolio stacked up against a simple benchmark is one of the most useful things you can do as an investor, because it turns a vague feeling into an actual data point.

Across accounts, it gets worse

Most people don’t invest through a single account. There’s a TFSA, an RRSP, maybe a non-registered account, maybe a LIRA from an old pension. Some people have accounts at two or three different brokerages.

Each account shows its own return. Your TFSA might be up 15% because you loaded it with growth stocks. Your RRSP might be down 2% because it holds more conservative funds. Your non-registered account might be flat.

What’s your overall return? No brokerage tells you. They each show you a slice. You never see the full picture unless you calculate it yourself, which means pulling numbers from multiple apps, adjusting for contributions in each one, and doing the math. Almost nobody does this.

The result is that most people have a vague sense based on whichever account they check most often. If you mostly look at your TFSA and it’s doing well, you feel good. If you mostly look at your RRSP and it’s struggling, you feel worried. Neither feeling reflects the whole truth. Your actual portfolio performance is the combination of all of them, weighted by how much is in each one.

This fragmented view also makes it hard to know if your overall asset allocation makes sense. You might think you’re balanced because each individual account looks reasonable. But across all of them, you might be concentrated in ways you didn’t intend.

Why most people stop checking

Here’s the part that worries me most.

When the numbers are confusing, when you can’t tell what’s a return and what’s a deposit, when you can’t compare yourself to anything meaningful, when every account tells a different story, people stop looking.

Not because they don’t care about their money. Because looking doesn’t give them useful information. It just gives them a number they can’t interpret, which creates either false confidence or unnecessary anxiety. Neither one is helpful, so the rational response is to close the app and think about it later.

Later becomes next month. Next month becomes next year. And suddenly you’re five years into an investing strategy you’ve never actually evaluated. Your portfolio might be doing great. It might be quietly underperforming. It might be drifting into a concentration you’d never have chosen intentionally. You don’t know, because checking never felt like it gave you real information.

This is the actual risk. Not a market crash, not picking the wrong stock. The risk is disengagement. The risk is investing on autopilot for a decade because the feedback loop is broken. You put money in, a number goes up (usually), and you assume everything is fine. Maybe it is. But you should know, not assume.

It doesn’t have to be this complicated

The thing that frustrated me enough to eventually build Greenline was that none of this is a hard problem. The math exists. The data exists. Separating contributions from returns, calculating a real rate of return, comparing to a benchmark, combining accounts into one view: these are all solved problems. They’re just not solved in the places most people look.

Your brokerage has a specific job, and showing you a holistic, multi-account, benchmark-adjusted, contribution-aware picture of your performance isn’t really it. That’s a different kind of tool. If you’re weighing your options, I wrote a comparison of every approach to tracking a portfolio in Canada.

You can’t improve what you can’t measure. And right now, most investors aren’t really measuring. They’re glancing at a number, interpreting it as best they can, and hoping it means what they think it means. That’s not a plan. That’s a guess.

The good news is that once you can see the real numbers, everything gets simpler. You know if you’re on track. You know if your strategy is working. You know if that “up 12%” is actually up 12%, or if half of it was just your own money coming back to you wearing a disguise. And that clarity is what makes the difference between investing with intention and investing with crossed fingers.

How do I know if my portfolio is beating the market?

Compare your returns against a benchmark like the S&P 500 or a broad global index over the same period. If your portfolio returned 7% and the benchmark returned 12%, you underperformed. Most brokerages don’t show this comparison, so you’ll need to look up the benchmark return separately or use a tool that does it for you. The comparison only makes sense over the same time frame and accounting for the same type of return (time-weighted is the fairest comparison to a fund benchmark).

What’s the difference between time-weighted and money-weighted returns?

Time-weighted returns measure how well your investments performed, stripping out the effect of when you added or withdrew money. Money-weighted returns measure your personal experience, including the timing of your contributions. Time-weighted is better for comparing against a benchmark. Money-weighted tells you what you actually earned. Both are useful, and they can tell very different stories.

Should I combine all my investment accounts into one brokerage?

Not necessarily. There are good reasons to have accounts at multiple institutions (employer RRSP, better fees for certain account types, spousal accounts). The issue isn’t having multiple accounts. It’s not seeing them as one portfolio. What matters is having a way to see the combined picture across all of them so you can make informed decisions about allocation, rebalancing, and overall performance.
