In: Finance
You are running a small manufacturing process that has projected cash flows of -$13,000 in year one, $4,000 in year 2, $5000 in year 3, -$3,000 in year 4, $6,000 in year 5, and $7,000 in year 6, what is the interest rate that gives a net present value of zero. For information, In year four, you were required to make some upgrades to the process and that forced the negative $3,000. (Hint: Take the cash flow at the end of the year) (Give answer to one decimal place. That is, xx.x%)

Higher discount rate |
15.00% |
Step 1 : Higher discount rate - Lower discount rate |
5.00% |
Step2 : NPV at lower discount rate x step1 |
43.60 |
Step3 : NPV at lower discount rate - NPV at higher discount rate |
1,570.08 |
Step4 : Step2 / Step 3 |
2.78% |
Step 5 : Lower discount rate + step4 ---> IRR |
12.8% |
This way of computing the IRR would give an approximate rate. Excel function ---> "IRR" can be used to arrive at accurate IRR.
