Internal Rate of Return (IRR) and
Net Present Value (NPV)Net present value (NPV): the sum of the present values of all
cash inflows minus the sum of the present values of all
cash outflows.
The internal rate of return (IRR): (1) the discount rate that
equates the sum of the present values of all cash inflows
to the sum of the present values of all cash outflows;
(2) the discount rate that sets the net present value
equal to zero.
The internal rate of return measures the investment yield.

Example: Yield on a single receipt.
An investor can purchase a vacant lot for $28,371 and expects to sell it for $50,000 in 5 years. What is the expected IRR for this investment?

cash outflows.

h inflows
