Return on Investment (ROI) Formula

Return on Investment measures the total percentage increase or decrease of your investment from start to finish. It is best used for simple, one-time investments where the holding period isn't the primary focus.

Start\;ValueYour initial investment amount
End\;ValueThe final value or selling price
DividendsAny cash dividends or interest received during the holding period

Compound Annual Growth Rate (CAGR) Formula

CAGR smooths out your return over time, showing the steady annual growth rate required to reach your final value. This is the best metric for comparing investments held for different time periods.

End\;ValueYour final portfolio value
Start\;ValueYour initial investment
YearsThe total number of years you held the investment

Manual Step: Calculating ROI on a Stock Trade

You buy $10,000 worth of stock. You hold it for a while, collect $500 in dividends, and eventually sell it for $12,000.

1
1. Calculate Capital Gain
Find the profit from price appreciation.
2
2. Add Dividends
Add the cash dividends to find total profit.
3
3. Divide by Start Value
Divide total profit by the initial investment.
4
Result
Multiply by 100 to get your total percentage return.

Scenarios

  • WIN
    The Dividend ReinvestmentYou invest $10k in a stock. It grows to $12k in 5 years, but pays $2k in dividends. Your total gain is $4k, pushing your ROI to 40%.
  • LOSS
    The Inflation TrapYou hold $10k in cash. After 3 years, it's still $10k. Nominal ROI is 0%, but your real return is negative due to inflation.

What If Analysis

What if I double my time horizon?

Compound interest works best over time. Doubling your investment period often more than doubles your Total Effect due to compounding.

What if I add more capital?

Adding capital (DCA) isn't calculated here, but it smooths out volatility. Use our DCA Calculator for that specific scenario.

Frequently Asked Questions

What is CAGR?
Compound Annual Growth Rate (CAGR) measures the mean annual growth rate of an investment over a specified time period longer than one year.
Does this include taxes?
No, this calculator computes pre-tax gross returns. You should deduct capital gains tax to find net return.
Why is CAGR lower than my average annual return?
Simple average annual returns ignore the effects of compounding and volatility. Due to volatility drag (where negative years hurt more than positive years help), CAGR is mathematically almost always lower than simple average return.
