ROI, or return on investment, is the gain from an investment expressed as a percentage of what you invested. A $1,500 gain on a $5,000 investment is a 30% ROI.

How is ROI calculated?

The tool uses Net gain / Total invested x 100, where the net gain is the final value minus the amount invested. Enter either the final value or the net gain, plus the holding period.

What is annualized ROI and why does it matter?

Annualized ROI is the constant yearly return that produces the same final value over the holding period. It lets you compare investments of different lengths fairly, since a 30% return over two years is stronger than the same return over ten.

What is the difference between ROI and CAGR?

For a single beginning and ending value they are the same idea: CAGR is the annualized version of ROI. The ROI calculator reports both the total ROI and the annualized rate so you can read either.

Yes. If the final value is below the amount invested, the net gain is negative and the ROI is negative too. The tool labels this as a loss and shows the dollar figure.

Does the ROI calculator include dividends or regular contributions?

No. It models a single invested amount and a single final value. Dividends, contributions and withdrawals at different dates need a cash-flow-aware method such as XIRR.

It depends on the investment and benchmark. A reasonable rule is to compare annualized ROI against broad market indices and the risk-free rate, and to expect higher potential returns only with higher risk.

Is the ROI calculator free and private?

Yes. It runs entirely in your browser with JavaScript. Your investment figures are never uploaded, stored or logged.

Why does the annualized ROI matter more than the total ROI?

Because time inflates total returns. A 30% gain over ten years is only about 2.7% per year, which barely beats inflation, while the same gain over two years is a strong 14% annual return.

What is the difference between ROI and annualized ROI?

ROI is the total return over the whole holding period. Annualized ROI spreads that return over one year so investments of different durations can be compared. A 21 percent ROI over three years is about 6.6 percent a year.

Can ROI be negative and what does that mean?

Yes. A negative ROI means the investment returned less than its cost, so money was lost. A -25 percent ROI on a $4,000 investment means a $1,000 loss. The calculator shows the loss as a negative percentage and a negative gain.

What is the difference between ROI and profit margin?

ROI measures the gain on an investment relative to the amount invested, over a period of time. Profit margin measures the profit on sales relative to revenue for a single period. ROI answers "what did the money earn" while margin answers "what does the business keep from each sale".

Is a higher ROI always better?

Not automatically. Higher ROI usually comes with higher risk, less liquidity or a longer time horizon. The best investment is the one that meets your risk tolerance and goals, not simply the one with the biggest number.
