Investment Return Calculator
Calculate the total return on your investment, including capital gains and dividends.
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.
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.
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.
Scenarios
- WINThe 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%.
- LOSSThe 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.
