Given a collection of pairs (time, cash flow) representing a project, the NPV is a function of the rate of return. The internal rate of return is a rate for which this function is zero, i.e. the internal rate of return is a solution to the equation NPV = 0 (assuming no arbitrage conditions exist).
The modified internal rate of return (MIRR) is a financial measure of an investment's attractiveness. [31] [32] It is used in capital budgeting to rank alternative investments of unequal size. As the name implies, MIRR is a modification of the internal rate of return (IRR) and as such aims to resolve some problems with the IRR.
The internal rate of return (IRR) (which is a variety of money-weighted rate of return) is the rate of return which makes the net present value of cash flows zero. It is a solution r {\displaystyle r} satisfying the following equation:

When an individual being tested has a different pre-test probability of having a condition than the control groups used to establish the PPV and NPV, the PPV and NPV are generally distinguished from the positive and negative post-test probabilities, with the PPV and NPV referring to the ones established by the control groups, and the post-test ...
The internal rate of return (IRR) is the discount rate that gives a net present value (NPV) of zero. It is a widely used measure of investment efficiency. To maximize return, sort projects in order of IRR. Many projects have a simple cash flow structure, with a negative cash flow at the start, and subsequent cash flows are positive.

In business and for engineering economics in both industrial engineering and civil engineering practice, the minimum acceptable rate of return, often abbreviated MARR, or hurdle rate is the minimum rate of return on a project a manager or company is willing to accept before starting a project, given its risk and the opportunity cost of forgoing other projects.
