The cryptocurrency market is known for its volatility, making it essential for investors to track their potential gains and losses. A cryptocurrency returns calculator helps you quickly assess the performance of your digital asset investments based on key metrics like your initial investment, purchase price, current price, and the quantity of cryptocurrency you hold.
How the Calculator Works
This calculator uses a straightforward approach to determine your investment's profitability. Here's the breakdown of the calculations:
Number of Coins Calculation (if needed):
If the 'Initial Investment' and 'Purchase Price per Coin' are provided, the calculator first determines the number of coins you would have acquired:
Number of Coins = Initial Investment / Purchase Price per Coin
If 'Number of Coins Held' is already provided, this step is skipped, and that value is used directly.
Current Total Value:
This is the current market value of the cryptocurrency you hold:
Current Total Value = Number of Coins Held * Current Price per Coin
Total Profit or Loss:
This represents the absolute gain or loss in fiat currency (e.g., USD):
Total Profit/Loss = Current Total Value - Initial Investment
Percentage Return:
This shows the return on your investment as a percentage of your initial investment:
Percentage Return = (Total Profit/Loss / Initial Investment) * 100
Key Metrics Explained
Initial Investment: The total amount of fiat currency (e.g., USD) you initially spent to acquire the cryptocurrency.
Purchase Price per Coin: The price of one unit of the cryptocurrency at the time of your purchase.
Current Price per Coin: The current market price of one unit of the cryptocurrency.
Number of Coins Held: The total quantity of the cryptocurrency you currently possess.
Current Total Value: The total market worth of your holdings at the current price.
Total Profit/Loss: The absolute difference between your current total value and your initial investment. A positive number indicates profit, while a negative number indicates a loss.
Percentage Return: The profitability of your investment expressed as a percentage. This is a crucial metric for comparing returns across different investments.
