How to Use Bitcoin ETF Calculator
The Bitcoin ETF Calculator helps you evaluate your Bitcoin ETF investment performance including all fees and costs. Here is how to use it:
- Enter shares held — Input the number of ETF units you own (supports fractional shares).
- Enter buy price — The price per share at which you purchased the ETF.
- Enter current price — The live or last-known ETF price per share.
- Enter buy commission — Any brokerage fee paid when buying (enter 0 if commission-free).
- Enter sell commission — Estimated brokerage fee when selling.
- Enter annual management fee — The ETF's annual expense ratio (e.g., 0.25 for 0.25%). This is charged by the fund, not your broker.
- Enter holding days — How long you have (or plan to) hold the position, used to prorate the management fee.
- Read the results — The Bitcoin ETF Calculator shows net P&L, ROI, total cost basis, current market value, and accrued management fee.
- Run a price scenario — Enter a percentage change in the Scenario panel to project what your return would look like if the Bitcoin ETF price rises or falls by that amount.
Formula & Theory — Bitcoin ETF Calculator
The Bitcoin ETF Calculator uses straightforward finance formulas to break down all components of your investment return:
Total Cost Basis:
Total Cost = Shares × Buy Price + Buy Commission
Current Market Value:
Current Value = Shares × Current Price
Accrued Management Fee:
Accrued Fee = (Shares × Buy Price) × (Annual Fee % / 100) × (Holding Days / 365)
Net Proceeds (hypothetical sale today):
Net Proceeds = Current Value − Sell Commission − Accrued Fee
Net P&L:
Net P&L = Net Proceeds − Total Cost
Return on Investment (ROI):
$$\text{ROI} = \frac{\text{Net P&L}}{\text{Total Cost}} \times 100%$$
Price Scenario:
Scenario ETF Price = Current Price × (1 + Scenario Change %)
The Bitcoin ETF Calculator then reruns the same formulas with the scenario price to project hypothetical outcomes.
