Answer:
To calculate the MIRR, we first need to find the terminal value of the cash flows at the end of year 10 using the IRR:
PV = -$2,000
PMT = C
N = 10
IRR = 13%
Using the formula for the present value of an annuity, we can solve for C:
PV = C * [(1 - (1 + r)^-n) / r]
$2,000 = C * [(1 - (1 + 0.13)^-10) / 0.13]
C = $383.14
Now we can calculate the future value of the cash flows at the end of year 10 using the WACC as the discount rate:
PV = -$2,000
PMT = $383.14
N = 10
WACC = 8%
Using the formula for the future value of an annuity, we can solve for FV:
PV = PMT * [(1 - (1 + r)^-n) / r] + FV / (1 + r)^n
-$2,000 = $383.14 * [(1 - (1 + 0.08)^-10) / 0.08] + FV / (1 + 0.08)^10
FV = $4,353.34
Now we can calculate the MIRR using the formula:
MIRR = [(FV / PV)^(1/n)] - 1
MIRR = [($4,353.34 / $2,000)^(1/10)] - 1
MIRR = 0.1165 or 11.65%
Therefore, the project's MIRR is 11.65%.
