Calculation Parameters
Calculation Methodology:
PP = CapEx / (ΔC + ΔY)
Payback period without discounting. Where CapEx - capital expenditures, ΔC - direct savings, ΔY - indirect savings.
DPP = min(t : Σ(ΔC_t + ΔY_t) / (1 + r)^t ≥ CapEx)
Discounted payback period considering time value of money. Where r - discount rate.
ROI = (Σ(ΔC_t + ΔY_t) / CapEx) × 100%
Return on investment without discounting. Shows the ratio of total savings to capital expenditures.
ROI_discounted = (Σ((ΔC_t + ΔY_t) / (1 + r)^t) / CapEx) × 100%
Discounted return on investment considering time value of money.
NPV = -CapEx + Σ((ΔC_t + ΔY_t - OC_t) / (1 + r)^t)
Net present value considering operating costs. Where OC_t - operating costs in period t.
Amortization = CapEx / ServiceLife
Annual equipment depreciation. Where ServiceLife - service life of UAV and equipment in years.
All calculations consider risk factor (K_risk) adjusting expected savings.
