finance.investment-tax-efficiency Calculator
Calculates the tax efficiency of a investment portfolio management strategy from pre-tax and after-tax return, accounting for all applicable taxes. Tax-efficient investing can add 0.5–1.5% per year in after-tax return — achieved through asset location, tax-loss harvesting, and holding period management.

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.
