What is the Return on Investment (ROI) Calculator?
It helps you measure how much your investment has gained relative to the amount invested, and shows the annualized return for fairer comparison across different investment durations.
How It Works
You provide amount invested, amount returned, and investment time either by date range or years. The calculator computes investment gain, total ROI, annualized ROI, and the effective investment length.
Why It Matters
Absolute gain alone can be misleading without time context. ROI and annualized ROI help you benchmark performance, compare alternatives consistently, and make more informed capital allocation decisions.
