IRR Calculator

Calculate the Internal Rate of Return (IRR) for investments and business projects with equal interval cash flows. Analyze profitability, compare investment opportunities and make informed financial decisions using our free online IRR Calculator.

Investment Cash Flows

Enter your initial investment as a negative value followed by future cash inflows occurring at equal time intervals.

How the IRR Calculator Works

Enter Cash Flows

Enter your initial investment as a negative amount followed by all expected positive cash inflows at equal intervals.

Calculate IRR

The calculator finds the discount rate where the Net Present Value (NPV) of all cash flows equals zero.

IRR Formula

NPV = Σ [ Cash Flow ÷ (1 + IRR)t ] = 0

IRR is the discount rate that makes the Net Present Value (NPV) of all cash flows equal to zero. It assumes that all cash flows occur at regular intervals.

What is IRR (Internal Rate of Return)?

The Internal Rate of Return (IRR) is the discount rate at which the Net Present Value (NPV) of all future cash flows becomes zero. It is one of the most widely used financial metrics for evaluating investments, capital projects and business opportunities.

📈 Measure Investment Performance

IRR estimates the annualized rate of return generated by an investment, helping investors compare multiple opportunities.

💼 Project Evaluation

Businesses use IRR to determine whether a project is financially worthwhile by comparing it with the required rate of return.

IRR Formula

NPV = Σ [ Cash Flow ÷ (1 + IRR)t ] = 0

The Internal Rate of Return is the discount rate that makes the present value of all future cash inflows equal to the initial investment.

⚠ Assumes cash flows occur at regular intervals.
⚠ Multiple IRRs may exist for unconventional cash flows.

⚠ Should be used along with NPV for major decisions.

Best Practices for Investment Analysis

📈 Compare IRR with your required rate of return.

IRR Example

Suppose you invest ₹100,000 today and receive the following yearly cash inflows:

  • Year 1: ₹25,000
  • Year 2: ₹30,000
  • Year 3: ₹35,000
  • Year 4: ₹40,000
  • Year 5: ₹45,000

The IRR Calculator determines the annual discount rate at which the Net Present Value (NPV) of these cash flows becomes zero, helping you evaluate whether the investment meets your required return.
