How Does the Stock Return Calculator Work?
The calculator uses the following formulas:
Total Return (%) = (Ending Value + Dividends − Cost Basis) / Cost Basis × 100
CAGR = (Ending Value / Cost Basis)1/Years − 1
Cost Basis = (Shares × Purchase Price) + Buy Commission
Ending Value = (Shares × Sale Price) − Sell Commission
Simply enter your purchase details, current or sale price, dividends received, and holding period. The calculator will compute your return and show a detailed breakdown.

❓ Stock Return Calculator FAQ
What is total return?
Total return is the overall gain or loss on an investment, including both capital appreciation (price change) and income (dividends). It's the most complete measure of investment performance.
What is CAGR?
CAGR (Compound Annual Growth Rate) is the annualized rate of return that smooths out volatility over the holding period. It allows you to compare investments with different time horizons.
Should I include dividends in my return calculation?
Yes! Dividends are a significant part of total return, especially for long-term investments. Many investors underestimate their actual returns by looking only at share-price changes and ignoring dividends.
What is the historical S&P 500 average return?
The S&P 500 has historically returned about 10.7% per year on average (including dividends). This calculator uses that as a benchmark for comparison.
What is the difference between total return and CAGR?
Total return is the overall percentage gain over the entire holding period. CAGR is the annualized version , it tells you what the average yearly return would be if the investment grew at a steady rate.
Should I include commissions in my calculation?
Yes. Commissions reduce your net return. Including them gives you a more accurate picture of your actual profit or loss.
What if I don't know the exact holding period?
Enter your best estimate in years. The calculator uses this to annualize your return. You can enter fractions (e.g., 2.5 years) for partial periods.
How accurate is this calculator?
This calculator provides accurate estimates based on standard formulas. However, actual returns may vary due to factors like taxes, reinvestment timing, and market conditions. Use it as a planning tool.
Is this calculator free to use?
Yes, this calculator is completely free to use. No registration or personal data storage is required , all calculations run in your browser.
Can I use this for ETF investments?
Yes! ETFs are treated the same as stocks for return calculation purposes. Enter the purchase price, current price, dividends, and holding period just like a stock.
