Financial Formulas Reference
NPV Formula
NPV = Sum of [Cash Flow(t) / (1 + r)^t] for t = 0 to n
Where: r = discount rate, t = time period, n = total periods
IRR Definition
IRR = discount rate where NPV = 0
ROI Formula
ROI = (Net Benefit - Cost) / Cost * 100%
Payback Period
Simple Payback = Initial Investment / Annual Cash Flow
Discounted Payback = Time when cumulative discounted cash flows = 0
TCO Components
- Acquisition costs (hardware, software, implementation)
- Operating costs (maintenance, support, utilities)
- Personnel costs (training, salaries, contractors)
- Opportunity costs (downtime, productivity loss)
- End-of-life costs (decommissioning, migration)
