To determine whether the project is viable and ultimately profitable, the Net Present Value (NPV) and Internal Rate of Return (IRR) of the project are calculated. 1) To calculate the NPV, the formulae below is used: NPV= ∑PV- CF0 (Bragg and Bragg, 2018) Where PV= CFn where K=interest rate, CF= Cash Flow, PV=Present Value, t=Time (1+K)t
