Useful information on Internal Rate of Return and Cash Flow

Internal rate of return (IRR) is a method of deciding if a firm should make an investment based on long term projections. An investment is good if the corresponding IRR is greater than the rate of interest earned by different investments, such as investing in other projects, or banks deposits. The internal rate of return is the effective return rate earned on a capital investment, and does not just apply to real estate. The internal rate of return also includes allotment of an appropriate risk premium.

Internal rate of return is the discount rate that results in a in a net present value of null from a series of cash flows. If the internal rate of return is greater than the cost of capital investment in projects, it will add value for the firm and is therefore a profitable endeavor. Internal rate of return is an investment decision instrument; it helps to decide if a company or an individual should invest in a project, but it has a flaw in that it does not account for other available options. Net present value (NPV) is also an important factor. The internal rate of return is calculated by solving a polynomial. Many specialists use Sturm’s Theorem to find if the polynomial has a real solution. The internal rate of return equation can be solved via iterations; there is no way to solve it analytically.

Internal rate of return can be compared with a firm’s discounted rate of return; if the internal rate of return is greater than the firm’s discounted rate of returns, the investment is considered a good opportunity for the investor. If the investor evaluates an investment with some risks, the IRR will be higher than usual and as such will be accounted for and compensated in the calculation. Another factor which could influence the discounted yield is the yield of the market general, which introduces another factor which cannot be overlooked.

A measure named Modified Internal Rate of Return (MIRR) is used to give a measure of a cost of capital; and as such the intermediate cash flow is not usually invested at a projected internal rate of return. Some analysts prefer the net present value as a main indicator for an investment, but the internal rate of return is the executive’s favorite indicator and is generally considered more reliable than net present value. For executives, the internal rate of return is more intuitive and easy to use; analysts’opinion is generally still that net present value is still the best reflection of asset worth.

A project that has an internal rate of return greater than the discount rate will lead to a positive net value return. A lower net value return is the result of a higher discount rate, when the cash flow will be reduced. The internal rate of return is often the rate at which the value of cash outflow is equal to the value of cash inflow.

There are also some situations when the internal rate of return can be interpreted wrongly. When cash flow is negative, the internal rate of return doesn’t reflect the investments performance based on asset appreciation. Executives often misinterpret the internal rate of return as return on an investment; the internal rate of return provides only the breakeven rate while only taking account of liquid transactions.
