What Is the Crypto ROI Calculator?
This calculator measures the return on investment (ROI) of a cryptocurrency purchase. ROI expresses your gain or loss as a percentage of the money you originally put in, making it easy to compare different trades regardless of their size. It works for Bitcoin, Ethereum, altcoins, or any asset where you know what you paid and what it's worth now.
How to Use It
Enter the total amount invested (what you spent buying the asset, ideally including fees) and the current value of those holdings today. The tool returns your ROI percentage, your absolute profit or loss in dollars, and a summary of the figures you entered. A positive ROI means a gain; a negative ROI means a loss.
The Formula Explained
The ROI formula is:
$$\text{ROI} = \frac{\text{Current Value} - \text{Invested}}{\text{Invested}} \times 100\%$$
First, the change in value (profit or loss) is found by subtracting what you invested from the current value. That figure is then divided by the original investment and multiplied by 100 to convert it to a percentage.
Worked Example
Suppose you invested $1,000 in a token and it is now worth $1,500. Profit = \(\$1{,}500 - \$1{,}000 = \$500\). $$\text{ROI} = \frac{\$500}{\$1{,}000} \times 100 = 50\%$$ Your $1,000 grew by half its value.
FAQ
Does ROI account for time? No. ROI is a simple total return. A 50% ROI over one month is very different from 50% over five years, but the percentage is the same. Use an annualized return metric to compare across different time periods.
Should I include trading fees? For accuracy, add buy and sell fees to your invested amount and subtract them from current value, so the ROI reflects your true net result.
What does a negative ROI mean? It means your current value is less than what you invested — you are currently at a loss on that position.
