Even Cash Flow
Uneven Cash Flow
Future Cash Flow
Definition: The expected inflows (or outflows) of money at specific points in the future.
Key Point: These are projections, not current amounts. They can be even (same each period) or uneven (varying amounts).
Net Out-of-Pocket
Definition: The actual amount you personally pay after accounting for reimbursements, discounts, or other offsets.
Key Point: It’s the real cost borne by you, not just the gross expense.
Limitations
- It ignores the time value of money and cash flows after the payback point, so it should usually be combined with methods like NPV or IRR for better decisions
