finance.investment-unrealized-gain Calculator
Calculates unrealised gain or loss on a investment portfolio management position from current market value and original cost basis. Unrealised gains are not taxed until realisation — the Berkshire Hathaway model of never selling creates perpetual tax deferral on compounding gains.
Inputs
Principal
Upfront cost — the negative cash flow at time zero in NPV/IRR analysis.
Rate
Reference formula or conversion factor shown for context.
Years
Duration of the process. Make sure units match the rate inputs (seconds, minutes, or hours).
Results
initial investment
The upfront capital deployed at time zero. This is the negative cash flow from which all future returns are measured.
future value
What your investment will be worth at the end of the period. The power of compounding: $10,000 at 8% for 30 years grows to about $100,000.
total gain
The combined total across all inputs and components.
CAGR
Reference formula or conversion factor shown for context.
