ROI Calculator
Calculate Return on Investment (ROI), total investment gain, compound annualized ROI (CAGR), and holding duration across custom calendar dates or lengths.
Return on Investment (ROI) Calculator
Calculate the total return on investment, net monetary gain, compound annualized ROI (CAGR), and holding duration across custom calendar dates or investment lengths.
• Amount Invested: The initial principal capital expenditure or acquisition cost.
• Amount Returned: The final gross liquidation value, portfolio balance, or proceeds collected upon exit.
• Holding Duration: Specify either exact calendar dates or total years, months, and days to calculate the compound Annualized ROI (CAGR).

Capital Return Breakdown
Simple ROI vs. Annualized ROI (CAGR)
Return on Investment (ROI) is one of the most widely used profitability ratios across finance, business ventures, and personal portfolio management. Understanding how holding duration impacts compound annual returns is essential for accurate comparison.
Simple ROI Formula
Calculates the unadjusted percentage gain or loss over the entire investment holding period, regardless of how many years it took to achieve.
Annualized ROI (CAGR)
Standardizes performance on a per-year basis to allow fair comparison between an asset held for 6 months versus one held for 5 years.
Time Value of Money
A 100% simple return sounds spectacular, but achieving 100% in 1 year represents a 100% annualized return, whereas taking 10 years to achieve 100% represents only a 7.18% annual return.

ROI Calculator — Frequently Asked Questions
Q1 What is Return on Investment (ROI)? ▾
Return on Investment (ROI) is a fundamental profitability metric used to evaluate the efficiency and financial performance of an investment, calculated as: ROI = [(Amount Returned - Amount Invested) / Amount Invested] × 100.
Q2 What is the difference between Simple ROI and Annualized ROI (CAGR)? ▾
Simple ROI measures total percentage growth across the entire holding period regardless of duration. Annualized ROI (CAGR) computes the geometric compound yearly growth rate, allowing fair comparison between investments held over different lengths of time.
Q3 How is Annualized ROI calculated? ▾
Annualized ROI = [(Amount Returned / Amount Invested)^(1 / T) - 1] × 100, where T is the total investment holding period expressed in years.
Q4 Can ROI be negative? ▾
Yes. If the amount returned is less than the amount invested, the investment resulted in a net loss and the ROI will be negative. A total loss (proceeds = $0) yields an ROI of -100%.
Q5 What are the limitations of standard ROI? ▾
Standard ROI does not account for risk or volatility, the timing of interim cash flows (such as periodic dividends or capital calls), or inflation. For multi-period cash flows, Internal Rate of Return (IRR) is often used.
