How to Use?
- 1
Select your calculation mode
Choose from Return on Investment (ROI), Projected Final Value, Required Initial Investment, or Required Time Period depending on what you want to solve for. The form automatically adjusts to show only the inputs relevant to your chosen mode.
- 2
Enter your investment details
Type your initial investment amount and any monthly contributions you plan to make. For ROI mode, also enter the expected final value. For projection modes, enter the expected annual return rate instead.

Set your time horizon
Enter the investment period in years. Longer time horizons benefit from compound growth but involve more uncertainty. Adjust the period to see how it affects your projected returns and CAGR.

Toggle Advanced Mode to include your expected inflation rate, capital gains tax rate, and annual management fees. This reveals the true after-tax, after-fee, inflation-adjusted return on your investment.

The calculator shows the ROI percentage, CAGR, net profit, and total capital deployed. The performance meter gives you a visual snapshot, and the growth chart illustrates the year-by-year trajectory of your portfolio.
