The internal rate of return (IRR) is the annualized rate that makes the net present value of all cash flows equal to zero.
IRR Formula
The Internal Rate of Return (IRR) represents the discount rate where the Net Present Value (NPV) of all cash flows equals zero. Mathematically, it is represented by the following equation:
NPV = Σ (C_t / (1 + IRR)^t) = 0
where t = 0, 1, 2, ..., n
In this formula:
- NPV = Net Present Value
- C_t = Net cash inflow/outflow during period t
- IRR = Internal Rate of Return
- t = Time period
- n = Total number of periods
How to Calculate Internal Rate of Return
The IRR Calculator solves this complex IRR equation using two robust numerical methods:
- Newton-Raphson Method: Our calculator's primary approach, offering fast convergence to the IRR value using function derivatives.
- Bisection Method: A reliable alternative method that systematically narrows the IRR range for guaranteed results.
Unlike other online calculators, our IRR Calculator displays both methods' results, giving you comprehensive insights into your investment's performance metrics.
How to Use Our IRR Calculator
1Enter Your Initial Investment
Our IRR Calculator assists you in evaluating investments. Begin by entering your initial investment, for example $10000. There is no cash return initially, so the net cash flow will be 0 - 10000 = -10000 (Net Cash Flow = Return - Investment).
This represents the capital you invest at the start (Period 0).
2Add or Remove Periods
Next, input your anticipated returns as positive amounts. The IRR Calculator will analyze these cash flows. The IRR Calculator allows you to extend the number of periods. Click 'Add Cash Flow' for longer investment durations.
You can eliminate periods using the trash icon. The IRR Calculator requires a minimum of two entries to function properly.
3Calculate and Interpret
Click 'Calculate IRR' to view your results. Our IRR Calculator employs two methods. You will receive results from both Newton's method and the Bisection method, providing you with more reliable figures.
The final calculated IRR is 8.9%, which means that if you obtain an initial funding of $10,000 from a bank loan at an interest rate lower than 8.9%, the project is profitable.

Key Considerations When Using IRR
- ✓Compare the result to what you expect to earn. This shows if an idea is good enough.
- ✓Use IRR alongside other financial metrics like NPV for a more comprehensive analysis.
- ✓Be aware of IRR's limitations, such as the reinvestment rate assumption and potential for multiple IRRs with non-conventional cash flows.
- ✓Consider the Modified Internal Rate of Return (MIRR) for more realistic reinvestment assumptions.
