Does ROI account for how long I held the investment?

No — this is total ROI over the whole holding period, not annualized. A 50% ROI over 1 year and over 10 years are very different outcomes even though the percentage is the same.

Yes — if the final value is lower than what you invested, ROI is negative, showing a loss rather than a gain.

How is ROI different from an annualized return?

ROI here reflects the total change over the entire holding period, regardless of how long that was. An annualized return spreads that same total gain or loss evenly across each year, which is more useful for comparing investments held for different lengths of time.

Should I include fees or taxes in my initial investment figure?

For the most accurate picture, include any fees paid to acquire the investment in your initial amount, and consider that taxes on gains aren't reflected in this raw ROI figure.

Can I use this to evaluate a business expense, not just a financial investment?

Yes — the same formula works for any scenario where you can express an initial cost and a resulting value, such as a marketing spend and the revenue it generated.

Mathematical Formula & Methodology

Here is the standard mathematical equation used to calculate this result accurately:

\text{ROI} = \frac{\text{Net Profit}}{\text{Total Cost}} \times 100\% = \frac{\text{Final Revenue} - \text{Initial Investment}}{\text{Initial Investment}} \times 100\%

Formula Variables Explained:
Measures the return on investment percentage and annualized rate of return across marketing campaigns, stocks, and real estate.

Step-by-Step Worked Example

An investment of $50,000 that returns $75,000 in gross revenue yields a net profit of $25,000: $\text{ROI} = \frac{25000}{50000} \times 100\% = 50\%$
