## What is the difference between IRR and ERR?

The economic rate of return (ERR) is a rate simply calculated from the cash flow of an investment that measures the profitability of the investment. This is done by using an external rate which is the hurdle rate or the (MARR). The (ERR) is different in its interpretation than the internal rate of return (IRR).

**What is the difference between a required rate of return and an expected rate of return?**

The required rate of return represents the minimum return that must be received for an investment option to be considered. Expected return, on the other hand, is the return that the investor thinks they can generate if the investment is made.

### What is IRR with example?

IRR is the rate of interest that makes the sum of all cash flows zero, and is useful to compare one investment to another. In the above example, if we replace 8% with 13.92%, NPV will become zero, and that’s your IRR. Therefore, IRR is defined as the discount rate at which the NPV of a project becomes zero.

**What IRR means?**

The internal rate of return (IRR) is a metric used in financial analysis to estimate the profitability of potential investments. IRR is a discount rate that makes the net present value (NPV) of all cash flows equal to zero in a discounted cash flow analysis. IRR calculations rely on the same formula as NPV does.

## What is a required rate of return?

The required rate of return (RRR) is the minimum amount of profit (return) an investor will seek or receive for assuming the risk of investing in a stock or another type of security.

**What is the difference between cost of capital and required rate of return?**

The cost of capital refers to the expected returns on the securities issued by a company. The required rate of return is the return premium required on investments to justify the risk taken by the investor.

### Why is NPV better than IRR?

IRR and NPV have two different uses within capital budgeting. IRR is useful when comparing multiple projects against each other or in situations where it is difficult to determine a discount rate. NPV is better in situations where there are varying directions of cash flow over time or multiple discount rates.

**Why is IRR calculated?**

The internal rate of return (IRR) is a core component of capital budgeting and corporate finance. Businesses use it to determine which discount rate makes the present value of future after-tax cash flows equal to the initial cost of the capital investment.

## Why do we calculate IRR?

Companies use IRR to determine if an investment, project or expenditure was worthwhile. Calculating the IRR will show if your company made or lost money on a project. The IRR makes it easy to measure the profitability of your investment and to compare one investment’s profitability to another.

**What is required rate of return formula?**

To calculate RRR using the CAPM: Subtract the risk-free rate of return from the market rate of return. Multiply the above figure by the beta of the security. Add this result to the risk-free rate to determine the required rate of return.

### Is required rate of return the same as WACC?

Since the required rate of return is a component of the WACC formula, the formula can be modified and used to identify the required rate of return. Where: WACC is the discount rate or required rate of return. E is the value of Equity.

**What is required rate of return?**

The required rate of return (RRR) is the minimum return an investor will accept for owning a company’s stock, as compensation for a given level of risk associated with holding the stock.
