Internal Rate of Return (IRR)

Internal Rate of Return (IRR)

Internal Rate of Return (IRR) • Is the rate of interest at which –

Internal Rate of Return (IRR) • Is the rate of interest at which – The present value of expected cash inflows from a project • Equals – The present value of expected cash outflows of the project.

Calculating the Internal Rate of Return

Calculating the Internal Rate of Return

Computing the IRR. . . • The IRR can be calculated by dividing the

Computing the IRR. . . • The IRR can be calculated by dividing the net investment by the annual cash flow to find the investments present value factor. • Then, refer to the Present Value of an Annuity of $1 table to find the corresponding rate.

Whoa! I never thought I would say this - but could I see that in equation form? I surely must be losing it!

Calculating the IRR Net Investment in Project ----------------- = PV Factor Annual Cash Flows

Calculating the IRR Net Investment in Project ----------------- = PV Factor Annual Cash Flows 379, 100 ------- = 3. 791 $100, 000 Present Value Factor

Calculating the IRR. . . • To determine the IRR, refer to the Present

Calculating the IRR. . . • To determine the IRR, refer to the Present Value of an Annuity of $1 table for 5 periods; • Scan across the line until you find a factor approximating 3. 791; • The rate at the top of the column is the Internal Rate of Return.

Calculating the IRR. . . • Use computer • Use financial calculator • Use

Calculating the IRR. . . • Use computer • Use financial calculator • Use trial and error

Trial and Error. . . Try a discount rate and calculate the NPV of

Trial and Error. . . Try a discount rate and calculate the NPV of the project using that rate.

Trial and Error. . . • If the NPV is less than zero, try

Trial and Error. . . • If the NPV is less than zero, try a lower rate. – A lower rate will increase the NPV. We are looking for the rate that will result in zero NPV.

Trial and Error. . . • If the NPV is greater than zero, try

Trial and Error. . . • If the NPV is greater than zero, try a higher discount rate. – Higher rate equals lower NPV.

Using the IRR. . . • A project is accepted if the internal rate

Using the IRR. . . • A project is accepted if the internal rate of return exceeds the required rate of return. – If IRR > RRR ==>Accept – If IRR = RRR ==>Accept – If IRR < RRR ==>Reject

Using the IRR. . . • Projects with higher IRRs are preferred to projects

Using the IRR. . . • Projects with higher IRRs are preferred to projects with lower IRRs, all other things being equal.
