Solution:-
Interest tax shield(ITS) = interest * debt * tax rate
= 0.07 * $2,367,487 * 0.24
= $39,773.7816
PV of ITS = ITS / r * [1-(1+r)-n]
= $39,773.7816 / 0.07 * [1-(1+0.07)-10]
= $39,773.7816 / 0.07 * 0.4916
= $279,325.5862
Incremental cost:
Upfront cost =C0 = $20,414
Annual cost = $7,903;post tax annual cost,C = pre tax cost * (1-tax rate)
= 7,903 * 76%
= 6,006.28
PV of the Incremental costs = C0 + C/r *[1-(1+r)-10]
= $20,414 + 6,006.28 / 0.07 (0.4916)
= $20,414 + $42,181.24
= $62,595.24
Hence NPV of this upgrade = Unlevered NPV + PV of ITS - PV of Inremental costs
= $342,464 + $279,325.58 -$62,595.24
= $559,194.34
