What this calculator does

A stock return calculator helps you evaluate investment performance by computing total return, annualized return, and the impact of dividends over a holding period. Total return includes both capital appreciation (price change) and dividends received, expressed as a percentage: Total Return = (Ending Value − Beginning Value + Dividends) / Beginning Value × 100. Annualized return converts total return into an equivalent yearly rate using the formula: Annualized Return = (1 + Total Return)^(1/years) − 1, allowing fair comparison of investments held for different time periods. For example, a stock bought at $50 that is now worth $85 after 5 years with $10 in cumulative dividends has a total return of 90% and an annualized return of about 13.6%. This tool is valuable for evaluating individual stock performance, comparing stock returns against benchmarks like the S&P 500, assessing portfolio performance, and making informed decisions about whether to hold or reallocate investments. Understanding both total and annualized returns gives you a clear picture of how your money is actually performing.

Stock Return Calculator FAQ

What is the difference between total return and annualized return?▾
Total return measures your complete gain or loss over the entire holding period as one number (e.g., "I made 90%"). Annualized return converts that into a yearly equivalent rate, allowing fair comparison of investments held for different lengths of time. A 90% total return over 5 years equals about a 13.6% annualized return.
What is a good annual return on stocks?▾
The S&P 500 has historically returned about 10% per year before inflation (roughly 7% after inflation) over long periods. Individual years vary wildly — from -37% in 2008 to +31% in 2019. A "good" return depends on the risk taken and the benchmark, but consistently beating 10% annualized over decades is exceptional.
Should I include dividends in my return calculation?▾
Absolutely. Dividends often account for a significant portion of total returns. Historically, dividends have contributed about 40% of the S&P 500's total return. Ignoring dividends drastically understates your actual investment performance. Always compare investments using total return, not just price appreciation.
How do I calculate return on investment (ROI)?▾
ROI = (Current Value − Amount Invested + Income Received) / Amount Invested × 100. If you invested $5,000 and your position is now worth $6,500 with $200 in dividends, your ROI is ($6,500 − $5,000 + $200) / $5,000 × 100 = 34%. For comparing investments of different durations, convert to annualized return.
