SCHG Performance Estimator
Your SCHG Investment Projection
$0.00
Formula Used: This calculator uses a compound growth formula adjusted for annual contributions and expense ratios. Each year's growth is calculated on the previous year's ending balance, plus the annual contribution, then reduced by the expense ratio.
What is SCHG?
The SCHG calculator is a tool designed to help investors visualize the potential future value of their investment in the Schwab U.S. Large-Cap Growth ETF (SCHG). SCHG is an exchange-traded fund that tracks an index of U.S. large-capitalization growth stocks. Growth stocks are typically companies expected to grow at an above-average rate compared to their industry peers. These companies often reinvest their earnings back into the business to fuel further expansion, rather than paying dividends.
Who should use it? This calculator is beneficial for current and prospective SCHG investors who want to understand how their investment might perform over various time horizons, considering factors like initial investment, ongoing contributions, expected market returns, and the ETF's expense ratio. It's particularly useful for long-term investors planning for goals such as retirement, education funding, or wealth accumulation.
Common Misconceptions: A common misconception is that past performance guarantees future results. While SCHG has historically shown strong performance, market conditions change, and future returns are not assured. Another misconception is that expense ratios are negligible; however, over long periods, even small percentages can significantly impact overall returns, which is why the SCHG calculator factors this in. Investors might also underestimate the impact of compounding growth and consistent contributions.
SCHG Performance Formula and Mathematical Explanation
The core of the SCHG calculator relies on a compound growth formula, adapted to include annual contributions and the impact of the ETF's expense ratio. The calculation proceeds year by year.
Let:
- $PV$ = Present Value (Initial Investment)
- $C$ = Annual Contribution
- $r$ = Assumed Average Annual Return (as a decimal)
- $e$ = Expense Ratio (as a decimal)
- $n$ = Number of Years
- $FV_y$ = Future Value at the end of year $y$
The net annual growth rate is $(r – e)$.
Year 1:
$FV_1 = (PV + C) \times (1 + r – e)$
Year 2:
$FV_2 = (FV_1 + C) \times (1 + r – e)$
General Formula for Year $y$:
$FV_y = (FV_{y-1} + C) \times (1 + r – e)$
This iterative process is applied for the total number of years ($n$). The calculator also tracks total contributions and total growth separately for clarity.

Practical Examples (Real-World Use Cases)
Example 1: Long-Term Retirement Savings
Scenario: Sarah is 30 years old and wants to invest in SCHG for retirement. She invests $15,000 initially and plans to contribute $5,000 annually for the next 35 years. She assumes an average annual return of 10% and SCHG's expense ratio of 0.04%.
Inputs:
- Initial Investment: $15,000
- Annual Contributions: $5,000
- Investment Horizon: 35 years
- Assumed Average Annual Return: 10%
- SCHG Expense Ratio: 0.04%
Projected Outputs (using the calculator):
- Total Contributions: $190,000 ($15,000 + 35 * $5,000)
- Estimated Ending Value (Net of Fees): Approximately $1,150,000
- Total Growth: Approximately $960,000
Financial Interpretation: This example highlights the power of long-term compounding and consistent contributions. Sarah's initial $15,000, combined with regular additions, could grow significantly over 35 years, demonstrating SCHG's potential for wealth building. The net ending value accounts for the small but persistent drag of the expense ratio.
Example 2: Medium-Term Growth Investment
Scenario: Mark is investing in SCHG for a down payment on a house in 7 years. He invests $5,000 initially and adds $2,000 annually. He conservatively estimates an average annual return of 8% and uses SCHG's expense ratio of 0.04%.
Inputs:
- Initial Investment: $5,000
- Annual Contributions: $2,000
- Investment Horizon: 7 years
- Assumed Average Annual Return: 8%
- SCHG Expense Ratio: 0.04%
Projected Outputs (using the calculator):
- Total Contributions: $19,000 ($5,000 + 7 * $2,000)
- Estimated Ending Value (Net of Fees): Approximately $27,500
- Total Growth: Approximately $8,500
Financial Interpretation: This shows how SCHG can be used for medium-term goals. While the growth is less dramatic than in the long-term example, the consistent contributions and compounding still provide a substantial boost over the initial investment, helping Mark reach his savings target faster. This example also underscores the importance of realistic return expectations for shorter timeframes.
How to Use This SCHG Calculator
Using the SCHG calculator is straightforward. Follow these steps to get your personalized performance projection:
- Enter Initial Investment: Input the lump sum amount you are starting with in SCHG.
- Enter Annual Contributions: Specify the amount you plan to add to your SCHG investment each year. If you don't plan to add more, enter 0.
- Set Investment Horizon: Enter the number of years you intend to hold the SCHG ETF.
- Input Assumed Average Annual Return: Provide your best estimate for the ETF's average yearly growth rate. Historical data can be a guide, but remember past performance is not indicative of future results. Use a realistic percentage (e.g., 10 for 10%).
- Enter SCHG Expense Ratio: Input the ETF's expense ratio. For SCHG, this is typically very low (e.g., 0.04).
- Click 'Calculate Performance': The calculator will process your inputs and display the results.
How to Read Results:
- Main Result (Ending Value Net of Fees): This is the primary output, showing the projected total value of your investment at the end of your specified horizon, after accounting for growth, contributions, and the ETF's annual fees.
- Total Contributions: This shows the sum of your initial investment and all the annual contributions made over the period.
- Total Growth: This represents the earnings generated by your investment, calculated as Ending Value minus Total Contributions.
- Annual Performance Breakdown Table: Provides a year-by-year view of how the investment is projected to grow, including gross growth, fees deducted, and net growth.
- Investment Growth Chart: Visually represents the projected ending balance and total contributions over the years.
Decision-Making Guidance: Use the results to assess if your current investment strategy aligns with your financial goals. If the projected outcome doesn't meet your expectations, consider adjusting your inputs: increasing contributions, extending the investment horizon, or revising your return assumptions (while remaining realistic). The calculator helps you understand the trade-offs between risk, time, and potential reward with SCHG.
Key Factors That Affect SCHG Results
Several factors significantly influence the projected performance of SCHG and, consequently, the output of this SCHG calculator. Understanding these can lead to more informed investment decisions:
-
Market Performance & Economic Conditions: SCHG's performance is directly tied to the broader stock market, particularly the large-cap growth sector. Economic downturns, recessions, or shifts in investor sentiment towards value stocks can negatively impact growth stock returns. Conversely, strong economic growth and favorable market conditions can boost performance.
-
Assumed Rate of Return: This is a critical input. Overestimating returns can lead to disappointment, while underestimating might cause you to miss opportunities. Historical averages (like SCHG's historical ~10-15% annual returns) are often used, but future returns are uncertain and can vary significantly year to year.
-
Investment Horizon: Longer investment horizons allow for greater compounding and provide more time to recover from market downturns. A 30-year investment is likely to yield vastly different results than a 5-year one, even with the same annual return. This calculator demonstrates this effect.
-
Expense Ratio: While SCHG has a low expense ratio (0.04%), this fee is charged annually and compounds over time. Even small fees erode returns. A higher expense ratio on a different ETF could significantly reduce the final value compared to SCHG over decades.
-
Consistency of Contributions: Regular, disciplined contributions (dollar-cost averaging) can significantly enhance total returns, especially in volatile markets. They ensure you buy more shares when prices are low and fewer when high, smoothing out the purchase price over time. The calculator shows the impact of these additions.
-
Inflation: While not directly calculated, inflation erodes the purchasing power of future returns. A projected $1 million in 30 years will not have the same buying power as $1 million today. Investors should consider their real return (return after inflation) when setting long-term goals.
-
Tax Implications: Investment gains and dividends are often subject to taxes. The timing of sales, type of account (taxable vs. tax-advantaged like an IRA or 401k), and capital gains tax rates can significantly affect the net amount you keep. This calculator assumes pre-tax growth.
Frequently Asked Questions (FAQ)
Q1: Is SCHG a good investment for beginners?
SCHG can be suitable for beginners due to its diversification across large U.S. companies and its low cost. However, growth stocks can be more volatile than broad market or value-oriented funds. Beginners should understand the risks and consider their risk tolerance and investment horizon. Consulting a financial advisor is recommended.
Q2: How accurate are the results from this SCHG calculator?
The calculator provides an estimate based on the inputs you provide, particularly the assumed average annual return. Actual market returns fluctuate significantly year to year and cannot be predicted with certainty. The expense ratio is factored in accurately, but other variables like taxes and fees are not included.
Q3: What does the "Net of Fees" mean in the results?
"Net of Fees" means the projected ending value has had the ETF's annual expense ratio deducted proportionally over the investment period. For SCHG, this is a small percentage (e.g., 0.04%), but it's important for long-term accuracy.
Q4: Should I rely solely on this calculator for my investment decisions?
No. This calculator is a tool for projection and education. It should be used alongside thorough research, an understanding of your personal financial situation, risk tolerance, and potentially advice from a qualified financial professional.
Q5: What is the difference between SCHG and other ETFs like VOO or VTI?
SCHG focuses on large-cap growth stocks. VOO (Vanguard S&P 500 ETF) tracks the S&P 500 index, which includes large-cap stocks across various styles (growth and value). VTI (Vanguard Total Stock Market ETF) offers even broader diversification, covering large, mid, and small-cap U.S. stocks. Each has different risk/return profiles.
Q6: Can I use this calculator for other ETFs?
Yes, you can adapt the calculator for other ETFs by changing the 'Assumed Average Annual Return' and 'Expense Ratio' inputs to match the specific ETF you are interested in. Ensure the return assumption is realistic for that particular ETF's investment strategy.
Q7: What happens if the market has a negative year?
The calculator uses an average annual return, which smooths out volatility. In reality, the market experiences ups and downs. A negative year would reduce the ending balance for that specific year, and the subsequent year's growth would be calculated on that lower balance. Long-term investors aim to ride out these downturns.
Q8: How do I copy the results?
Click the "Copy Results" button. This will copy the main projected ending value, total contributions, total growth, and key assumptions (like the assumed return and expense ratio) to your clipboard, which you can then paste into a document or note.
