ROI Calculation Methods

Simple ROI Formula

Basic ROI Calculation:

ROI = (Net Profit / Investment) × 100

Example Calculation:

Traditional System 5-Year Cost: $115,000
VoIP System 5-Year Cost: $48,000
Savings: $67,000
Investment: $12,000
ROI = ($67,000 / $12,000) × 100 = 558%

Payback Period

Payback Period Formula:

Payback Period = Initial Investment / Annual Savings

Example Calculation:

Initial Investment: $12,000
Annual Savings: $13,400
Payback Period = $12,000 / $13,400 = 0.9 years (11 months)

Net Present Value (NPV)

NPV Calculation:

NPV = Σ (Cash Flow / (1 + Discount Rate)^Year) - Initial Investment

Example with 10% Discount Rate:

Year 0: -$12,000 (Initial Investment)
Year 1: +$13,400 (Annual Savings)
Year 2: +$13,400
Year 3: +$13,400
Year 4: +$13,400
Year 5: +$13,400

NPV = -$12,000 + $13,400/1.1 + $13,400/1.1² + $13,400/1.1³ + $13,400/1.1⁴ + $13,400/1.1⁵
NPV = -$12,000 + $12,182 + $11,075 + $10,068 + $9,153 + $8,321
NPV = $38,799
