This advanced calculator offers more flexibility for complex investment scenarios.
How to Use This Tool
Initial Investment: Enter the total upfront cost.
Cash Flow ($): Enter the cash flow amount for a period or a series of
identical periods.
Periods: If a cash flow amount repeats, enter the number
of consecutive periods it occurs (e.g., $5000 for 3 periods).
Length of Each Period: Specify the duration of a single period in
months. For annual cash flows, enter 12. For quarterly, enter 3.
Interpreting the Result
The calculator provides both the IRR for the specified period and the Annualized IRR, which
is crucial for comparing investments with different period lengths on an equal basis.
