Measuring Bitcoin Investment Returns with ROI and DCA Calculators
Summary
The document explains how a Bitcoin return on investment calculator estimates the percentage gain or loss between an initial investment and its current or realized value. It identifies the inputs needed: total amount invested, purchase price or date, and final value or sale proceeds. The stated formula divides the change in value by the initial investment and expresses the result as a percentage. A worked example demonstrates the calculation for a single purchase.
For dollar-cost averaging, it recommends using a specialized calculator that accounts for each contribution, its interval, and the investment period, since one purchase price cannot represent a series of buys. It suggests comparing returns over the same period with another asset to assess relative performance. Basic ROI is backward-looking and generally omits fees and taxes; the document also notes that it does not adjust for volatility or risk. Its calculator guidance is introductory, not a full portfolio evaluation method.
Key ideas
- ROI expresses the change between an investment’s initial cost and final value as a percentage of initial cost.
- A single-purchase calculation needs the amount invested, purchase price or date, and current or sale value.
- DCA performance requires accounting for multiple purchases, their amounts, timing, and the evaluation period.
- Comparisons with other assets are more meaningful when measured across the same dates.
- Simple ROI may omit fees and taxes and does not account for volatility or risk-adjusted performance.
