Worked examples
Example 1. Inputs:
- Buy price: 30,000 USD per BTC
- Sell price: 45,000 USD per BTC
- Amount of bitcoin: 1 BTC
Results:
- Total profit or loss: $15,000.00
- Amount invested: $30,000.00
- Current value: $45,000.00
- Return on investment: 50.0%
How this is worked out: Invested = 30000 x 1 = 30000. Returned = 45000 x 1 = 45000. Gain = 45000 - 30000 = 15000. ROI = 15000 / 30000 x 100 = 50.
Example 2. Inputs:
- Buy price: 20,000 USD per BTC
- Sell price: 15,000 USD per BTC
- Amount of bitcoin: 0.25 BTC
Results:
- Total profit or loss: -$1,250.00
- Amount invested: $5,000.00
- Current value: $3,750.00
- Return on investment: -25.0%
How this is worked out: Invested = 20000 x 0.25 = 5000. Returned = 15000 x 0.25 = 3750. Gain = 3750 - 5000 = -1250. ROI = -1250 / 5000 x 100 = -25.
Example 3. Inputs:
- Buy price: 20,000 USD per BTC
- Sell price: 0 USD per BTC
- Amount of bitcoin: 1 BTC
Results:
- Total profit or loss: -$20,000.00
- Amount invested: $20,000.00
- Current value: $0.00
- Return on investment: -100.0%
How this is worked out: A sell price of 0 returns nothing. Invested = 20000 x 1 = 20000. Returned = 0. Gain = 0 - 20000 = -20000. ROI = -20000 / 20000 x 100 = -100.
Limitations

- Assumes all the bitcoin was bought at one price.
FAQs
- Q: What sell price should I enter?
- A: Enter the price of one bitcoin in US dollars at the moment you want to measure. The tool does not fetch live prices.
- Q: Does the result include fees or taxes?
- A: No. The result is the price change multiplied by the amount of bitcoin. Trading fees and taxes are not included, so subtract them yourself for a net figure.
- Q: What if I bought at more than one price?
- A: The tool takes one buy price. For several purchases, enter the weighted average price: total cost divided by total bitcoin bought.
- Q: Can I enter a sell price of zero?
- A: Yes. A sell price of zero shows the whole amount invested as a loss, which is a return of -100%.
