How this calculator works
The result depends on the numbers you enter and the assumptions shown below.

ROI measures the efficiency of an investment. Total ROI = (Final Value - Initial Investment) / Initial Investment × 100. Annualized ROI adjusts for the holding period using CAGR.

Review the inputs carefully and treat the output as an estimate. For decisions involving money, taxes, health, law, or security, compare the result with trusted professional guidance when needed.
