How to Track Your Investment Performance
Tracking performance does not mean refreshing your brokerage app every hour. Here is the right way to measure your portfolio: correct benchmarks, useful metrics, and a quarterly review schedule.
Don't have time? Here's what you need to know:
- 1Compare your portfolio to a blended benchmark that matches your actual stock/bond allocation, not just the S&P 500
- 2Check your portfolio quarterly, not daily -- more frequent checking leads to worse decision-making
- 3Track total return (including dividends), asset allocation drift, and blended expense ratio
- 4Your brokerage account tools plus a simple quarterly spreadsheet are all the tracking most investors need
Pick the Right Benchmark (Not Just the S&P 500)
If your portfolio is 70% U.S. stocks, 20% international stocks, and 10% bonds, comparing it to the S&P 500 alone makes no sense. Bonds and international stocks will drag your total return below the S&P 500 in most years -- that does not mean you are doing something wrong.
Match your benchmark to your actual allocation. A simple blended benchmark: 70% total U.S. stock market return + 20% total international return + 10% total bond return. Most brokerages display your total return automatically. You can also track against a similar target-date fund as a sanity check.
The 4 Metrics Worth Tracking
Total return (including dividends): This is the number that actually matters. It includes both price appreciation and reinvested dividends. Time-weighted return vs. money-weighted return: Time-weighted removes the effect of when you added money; money-weighted reflects your actual experience. Most brokers show time-weighted by default.
Asset allocation drift: Check whether your actual allocation still matches your target. If you wanted 80/20 stocks/bonds and you are now at 87/13, it is time to rebalance. Total fees paid: Add up your ETF expense ratios weighted by holding size. If your blended expense ratio is above 0.15%, look for cheaper alternatives.
| Metric | Where to Find It | How Often to Check |
|---|---|---|
| Total return (YTD and since inception) | Brokerage account summary page | Quarterly |
| Asset allocation breakdown | Portfolio analysis tool in your broker | Quarterly |
| Expense ratio (blended) | Fund detail pages; calculate weighted average | Annually |
| Contributions vs. investment gains | Transaction history or performance page | Annually |
| Comparison to blended benchmark | Manually or use Morningstar/Portfolio Visualizer | Quarterly |
The Right Review Schedule (Hint: Not Daily)
Check your portfolio quarterly -- four times a year. That is January, April, July, October. During each review, look at three things: (1) Is your asset allocation still on target? (2) Have you been contributing consistently? (3) Are you still on track for your goals?
Once a year, do a deeper review. Recalculate your required savings rate, check for better fund options, review beneficiaries, and make sure your tax strategy still makes sense. This annual review should take about 30-60 minutes.
Tip: Use the ETF return calculator during your annual review to project whether your current savings rate will hit your goal. Adjust contributions if needed.

Free Tools for Performance Tracking
Your brokerage's built-in tools are usually sufficient. Fidelity's "Full View" and Schwab's "Portfolio Performance" pages show total return, allocation, and cost basis. For a more detailed view, Portfolio Visualizer (free tier) lets you backtest and analyze performance against benchmarks.
A simple spreadsheet also works well. Track four columns each quarter: date, total contributions, current balance, and total return percentage. After a few years, this becomes a powerful record of your progress. Seeing your balance grow from $5,000 to $50,000 is excellent motivation.
Frequently Asked Questions
Why does my brokerage show a different return than what I calculate?
Most likely it is the difference between time-weighted and money-weighted returns. If you added a large contribution right before a big gain, your money-weighted return will be higher than the time-weighted return. Neither is wrong; they measure different things.
Should I track individual ETF performance or just my total portfolio?
Focus on total portfolio performance. Individual holdings will always look better or worse than the average, which can create unnecessary anxiety. What matters is whether your overall portfolio is on track for your goals, not whether VXUS is lagging this quarter.
How do I know if my portfolio is performing well?
Compare it to a blended benchmark matching your allocation. If you are within 1-2% of that benchmark, you are doing great. If you are consistently lagging by more, check your expense ratios and make sure your money is actually invested (not sitting in cash).
