How to Calculate IRR on Normal Calculator
Introduction & Importance
Internal Rate of Return (IRR) is a crucial metric in finance, helping investors determine the profitability of an investment. It’s the discount rate at which the net present value (NPV) of a series of cash flows equals zero. Understanding and calculating IRR is vital for making informed investment decisions.
How to Use This Calculator
- Enter the cash flow amount in the ‘Cash Flow’ field.
- Enter the period (in years) in the ‘Period’ field.
- Click ‘Calculate’.
Formula & Methodology
The IRR formula is derived from the net present value (NPV) formula. It involves finding the discount rate (r) that makes the NPV of a series of cash flows equal to zero. The formula is:
NPV = ∑ [CFt / (1 + r)^t] – Initial Investment = 0
Where CFt is the cash flow in period t, and r is the discount rate (IRR) we’re trying to find.

Expert Tips
- IRR assumes that cash flows are reinvested at the IRR rate, which may not always be realistic.
- IRR is sensitive to the timing of cash flows. A small change in cash flow timing can significantly affect the IRR.
Interactive FAQ
What is the difference between IRR and NPV?
IRR is the discount rate that makes the NPV of a series of cash flows equal to zero. NPV, on the other hand, is the present value of a series of cash flows, discounted at a given rate.
