Total Return (ROI)
66.00%
Performance Analysis
Your investment returned 66.0% in total, or 10.67% per year after including $1,200 of income. That is in line with or above the historical long-run return of the US stock market.
Understanding Your True Investment Return
Total return is the single most important scorecard for any investor. It measures everything an investment has actually done for your wealth: price appreciation plus every dividend, interest payment, and distribution you collected along the way, expressed as one percentage of the money you originally put in. Without it, US investors routinely misjudge their performance, because a fund that rose 40% while paying no income can still lose to a fund that rose 30% and handed over a stream of dividends. For American households building wealth in taxable brokerage accounts, 401(k) plans, and IRAs, tracking total return matters more than ever. Markets have delivered long stretches of 20%+ gains and brutal 30%+ drawdowns, and the only honest way to compare a stock, a mutual fund, or your own portfolio against a benchmark like the S&P 500 is to count every dollar that actually came back to you. This tool consolidates return on investment (ROI) and annualized return into one calculation so you can judge results in minutes.
The Total Return Formula Explained
The calculator uses two standard formulas. Total return (ROI) = [(Ending Value + Income Received - Beginning Value) / Beginning Value] x 100. This captures both capital appreciation and income, matching the 'total return' convention used by fund companies and Morningstar. The annualized return then converts that lump-sum gain into a per-year rate: Annualized Return = [(1 + ROI/100)^(1/Years) - 1] x 100, which is mathematically identical to the geometric average used for CAGR. The annualization step is the crucial one. A 60% total gain sounds spectacular until you learn it took 15 years, which works out to only 3.2% per year. Likewise, a 9% gain over six months is a blistering 18%+ annualized. By combining the two metrics, this tool prevents both flattering a slow winner and panicking over a fast one. Dividends are added in as received (not reinvested) in this tool, so for a reinvestment-style comparison, include reinvested distributions in your ending value.
Expert Insights
Income Is Half the Story for US Equities
Dividends represent roughly 40% of the S&P 500's long-run total return when reinvested. Investors who track only price changes systematically understate their performance, especially for value stocks and equity income funds. Always add distributions received to the ending value, or better, use statements that report total return directly.
Annualize Before You Conclude
Holding periods differ wildly between investments, making raw ROI comparisons meaningless. A rental property held 20 years and a stock held 2 years cannot be compared side by side until both are converted to annualized returns. The annualized figure is the common yardstick that lets you rank every asset you own against a single benchmark like a target-date fund.
Compare Against the Right Benchmark
Beating a savings account is not evidence of skill — the right test is the relevant risk-free alternative plus a premium for risk. A US stock portfolio should be measured against a broad stock index like the S&P 500 or total market fund. If your annualized return trails the index after fees over multiple years, the evidence points to simpler, cheaper indexing.
Actionable Tips
- 1
Gather Every Dollar of Income
Before running this calculation, pull your brokerage or 401(k) statements for the full holding period and sum all dividends, interest, and capital gains distributions. Missing income is the number one source of understated returns, and for long holding periods the omitted income can exceed the price gain itself.

Set a Review Calendar
Compute your annualized return for each major position once per year and log it. A spreadsheet with beginning value, ending value, income, and dates turns vague feelings about performance into hard evidence, making it far easier to trim chronic losers without emotion.

Factor in Taxes Before Bragging
Total return is a pre-tax number. Subtract what you owe the IRS — ordinary rates on interest and short-term gains, 0/15/20% on long-term gains — to see the return you actually keep. Two identical 9% investments can differ by more than 3 percentage points after tax depending on turnover and account type.
Real-World Examples
Marcus Realizes His Tech Stock Underperformed
Marcus, a software engineer in Austin, held a single tech stock that rose from $15,000 to $19,800 over four years with no dividends. Pleased with 32% total, he ran the numbers and found only 7.2% annualized — well below the S&P 500's double-digit run over the same span. He rebalanced half the position into a total-market index fund.
Elena Discovers Dividends Carried Her Portfolio
Elena, a retired teacher in Ohio, assumed her utility stock portfolio had disappointed her because share prices barely moved. Adding $4,800 of accumulated dividends to her calculation flipped the verdict: 38% total return over five years, or 6.7% annualized — respectable income-oriented performance that was quietly funding her budget.
Devon Stops Averaging Down on a Loser
Devon, a marketing manager in Atlanta, had doubled down on a losing stock three times. His beginning value was $18,000 with an ending value of $10,200 over three years — a -43% total return and -17.3% annualized. The annualized figure, not the raw loss, is what finally convinced him the thesis was broken, and he harvested the tax loss.
Glossary of Terms
- Total Return
- The complete gain or loss on an investment, combining price appreciation with all income such as dividends and interest, expressed as a percentage of the initial investment.
- Annualized Return
- The constant yearly rate that would produce the same cumulative gain over the actual holding period, allowing investments held for different lengths of time to be compared fairly.
- Benchmark
- A reference investment, usually a broad index like the S&P 500, used to judge whether a portfolio or fund has added value beyond simply buying the market.
