# Calculation Of Internal Rate Of Return, External Rate Of Return Of A Project

Question

The estimated values of the yearly ATCF (after tax cash flows) of a Project are given in the Table below. The duration of the Project is six years. The initial cost of the Project is \$2,800,000. MARR (the minimum attractive rate of return) is 12%.

 End of year 1 2 3 4 5 6 ATCF \$620,000 \$620,000 \$620,000+\$X \$620,000 \$620,000 \$620,000+\$Y

Determine:

• the value of X that would make the IRR (internal rate of return) of the Project equal to 15% if Y = 3X
• the IRR (internal rate of return) of the Project if X = 400,000 and Y= 1,000,000
• the value of X that would make the ERR (external rate of return) of the Project equal to 15% if Y = 800,000
• the ERR (external rate of return) of the Project if X = Y = 800,000
• the value of X that would make the equivalent uniform annual value of the Project cash flow equal to \$980,000 if Y = 4X

Summary

The question belongs to Finance and it discusses about calculation of internal rate of return, external rate of return and annual value of cash flow for a project.

Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
