Internal レート of リターンとは何ですか
Internal レート of リターン (IRR) is the 割引 レート that makes the net present 値 (NPV) of all cash flows from a project equal to zero. It represents the expected annualized レート of リターン for an 投資. IRR is widely used in capital budgeting to compare the profitability of different investments. The Modified IRR (MIRR) addresses some limitations of traditional IRR by assuming reinvestment at a different レート.
使い方
Enter your initial 投資, select a cash flow pattern (even, growing, or custom), specify the 番号 of years and 年次 cash flows. You can also add terminal 値 and specify reinvestment/financing rates for MIRR calculation. The 計算機 displays IRR, MIRR, NPV, and provides 投資 recommendations.
よくある質問
What is the Internal Rate of Return (IRR)?
The Internal Rate of Return (IRR) is a financial metric used to estimate the profitability of potential investments. It is the discount rate that makes the Net Present Value (NPV) of all cash flows (both incoming and outgoing) equal to zero.
How do I interpret the calculated IRR?
Generally, a higher IRR indicates a more desirable investment. If the calculated IRR is greater than your required rate of return (or cost of capital), the investment is considered profitable.
What is the difference between IRR and ROI?
ROI (Return on Investment) measures the total growth of an investment from start to finish as a percentage, while IRR measures the annualized growth rate and accounts for the timing of when money is received or paid.
Can I use this calculator for monthly cash flows?
Yes, but the result will correspond to the period of your cash flows. If you input monthly data, the resulting IRR will be a monthly rate. You would need to annualize it manually for comparison with yearly rates.
Why does the calculator say 'No Solution Found'?
This typically occurs when all cash flows are positive or all are negative. Mathematically, IRR requires at least one negative cash flow (investment) and one positive cash flow (return) to calculate a rate.
What are the limitations of using IRR?
IRR assumes that all positive cash flows are reinvested at the same rate as the IRR, which may not be realistic. It also struggles with unconventional cash flow patterns that have multiple sign changes, potentially resulting in multiple IRRs.
