An ETF (Exchange-Traded Fund) is a basket of securities — like stocks or bonds — that trades on a stock exchange throughout the day, just like individual stocks. Unlike mutual funds, ETFs typically have lower expense ratios and offer more flexibility since you can buy or sell them at market price any time during trading hours.
A broadly diversified equity ETF tracking a major index like the S&P 500 has historically returned around 7–10% annually before inflation. A 6–8% return is commonly used as a realistic planning benchmark after accounting for fees and market variability. Bond or conservative ETFs typically return less.
Compounding means your earnings generate their own earnings over time. When your ETF gains in value or pays dividends that get reinvested, those gains are added to your balance — and future returns are calculated on that larger amount. The longer you stay invested, the more powerful compounding becomes.
Nominal returns are the actual dollar figures your investment produces. Real returns strip out the effect of inflation, showing you how much purchasing power you've actually gained. For example, a 7% nominal return with 2.5% inflation yields roughly a 4.5% real return.
When you sell ETF holdings for a profit, that gain is typically subject to capital gains tax. The rate depends on your country, income level, and how long you held the investment. Using a tax-advantaged account (like an IRA, TFSA, or 401k) can shelter your gains from taxes, significantly improving long-term outcomes.
Regular contributions — monthly or annually — through a strategy called dollar-cost averaging can reduce the impact of market volatility. By consistently investing the same amount regardless of market conditions, you buy more shares when prices are low and fewer when prices are high, which can lower your average cost per share over time.
Diversification is the key tool for managing risk. Broad-market index ETFs spread exposure across hundreds or thousands of securities, reducing the impact of any single company's poor performance. Holding a mix of asset classes (equity, bond, international ETFs) and maintaining a long investment horizon further smooths out short-term volatility.
This calculator uses the rate of return you enter directly. To account for ETF expense ratios (typically 0.03%–0.75% per year), simply subtract the fund's expense ratio from your expected return before entering it. For example, if you expect a 7% return from a fund with a 0.20% expense ratio, enter 6.8%.
