Making (investing/economics/finance/accounting) Fun and Relatable
you can actually use a NPV function in Excel but its more valuable to learn the details
A dollar today is worth far more than a dollar tomorrow is the premise you need to start with
the 150 comes out immediately so its -150 to the NPV. The future flows of +100 and +150 are then discounted by (1.12) and (1.12)^2 to come up with your final number
-150+89.28 (100/1.12)+119.57 (150/1.12^2) for an final NPV of $58.59
Hope this helps
