A lot of modern portfolio trackers have started showing TWR. Learn what Time-Weighted Return actually is, why your Total PnL% can be negative while your stock is up 41%, and how to measure true performance.
If you have been using modern portfolio trackers recently, you have likely noticed a metric that was never on your traditional broker app: TWR (Time-Weighted Return).
For many investors, this number creates instant confusion. You open your dashboard, look at your holdings, and find that your familiar Total PnL % says one thing, while this new TWR % tells an entirely different story. Sometimes, one is deep in the red while the other is proudly green.
So what exactly is TWR? How is it different from the total gain/loss percentage everyone is used to? And why do you need it?
Let's break it down using a simple, relatable real-world example.
Imagine you decide to buy shares in OGDC. Here is how your journey unfolds:
Let's look at the numbers side by side:
| Event | Action / Market Move | Cash Flow | Position Value |
|---|---|---|---|
| Step 1 | Buy OGDC initial shares | -Rs. 10,000 | Rs. 10,000 |
| Step 2 | OGDC stock rises +50% | — | Rs. 15,000 |
| Step 3 | Top up position at peak | -Rs. 500,000 | Rs. 515,000 |
| Step 4 | OGDC stock declines -6% | — | Rs. 484,100 |
Now, look at what your broker app shows:
(-25,900 / 510,000) * 100 = -5.1%Your broker displays a big red -5.1%. It feels like a bad investment.
However, when you look at the OGDC price chart over that exact same holding period, the stock is actually UP +41%!
How is that possible?
Stock Growth: 1.50 (the +50% rally) × 0.94 (the -6% drop) = 1.41 (+41% overall)
The stock grew by 50%, gave back 6% from its peak, and ended 41% higher than where you started.
Congratulations: you just calculated the Time-Weighted Return (TWR) of your portfolio! It is +41%.
In a single-stock portfolio, TWR looks dead simple because it matches the underlying price return of the asset.
TWR measures the true performance of your investments, completely independent of when or how much cash you deposited or withdrew.
Why is this distinction so critical?
Suppose the KSE-100 Index rose +25% during this same timeframe.
If you only look at your -5.1% Total PnL, you might conclude:
That conclusion would be completely wrong.
Your stock selection was actually brilliant. OGDC delivered +41%, comfortably beating the KSE-100 benchmark's +25%.
The negative return in your bank account wasn't caused by a bad company. It was caused by bad timing—putting 50 times more capital into the stock after it had already rallied 50%, right before a short-term pullback.
Key Takeaway: Total PnL % blends stock-picking ability and market-timing luck into one messy number. TWR isolates the quality of your underlying assets so you can judge your investments fairly against market benchmarks.
Traditional Total PnL % works fine under one condition: you make a single deposit and never touch your portfolio again.
The moment you:
naive PnL % becomes heavily distorted by the size and timing of your cash flows. A large deposit right before a minor correction can wipe out months of great investment decisions on smaller capital, making skilled investors look incompetent.
Neither metric is "useless"—they simply answer two different questions:
| Question | Metric to Look At | What It Tells You |
|---|---|---|
| "Did I pick the right stocks?" | TWR (Time-Weighted Return) | Evaluates your investment strategy against benchmarks like the KSE-100 or mutual funds. |
| "Did my timing help or hurt my wallet?" | MWR / Total PnL | Measures the actual cash gain or loss in your pocket, accounting for your deposit timing. |
When you track both together:
In this single-stock example, TWR looks straightforward because it mirrors the underlying stock's price return. But where TWR becomes indispensable is in a multi-stock portfolio—where you hold 5 to 15 different companies, receive dividend payouts, rebalance winners, and deposit fresh savings across different months.
You can automatically track both your cash PnL and institutional-grade TWR using the FinHisaab Portfolio Tracker.

TWR stands for Time-Weighted Return. It is the global standard used by asset managers and institutional funds (GIPS compliance) to evaluate investment managers without penalizing them for client deposits or withdrawals.
Simple PnL % is computationally easy for basic broker databases because it only compares current market value with total cash deposits. Calculating daily time-weighted sub-periods requires tracking historical cash flow timestamps.
Yes. A true Time-Weighted Return calculation includes both capital appreciation and cash dividend distributions across each holding period.
Yes, exactly as shown in the OGDC example above. If you invest a small amount early and earn large percentage gains, then invest a massive amount at the peak before a small decline, your TWR will be positive (the asset rose overall) while your net cash PnL will be negative.
