Advanced Financial Calculations: Leasing, Discounting, and Tax Accounting

Leasing Analysis and Amortization (Paragraph 6)

Amortization Calculation

  • Initial Value: 21,000
  • Amortization (5 years): 21,000 / 5 = 4,200
  • Residual Book Value (VC) at Year End (after 3 years): 21,000 – (4,200 × 3) = 8,400
  • Residual Market Value (VR): 4,195 × 1.16 = 4,866.78

Financial Equivalence

The Present Value (VO) calculation confirms the initial value (i = 12%):

VO = 7,500 / (1 + 0.12) + 7,500 / (1 + 0.12)2 + 7,500 / (1 + 0.12)3 + 4,195.5 / (1 + 0.12)3 = 21,000
