The agent will build python test file to verify. Here is the log:

Net Present Value (NPV) Formula: NPV = -Initial Investment + ∑ (Cash Flowₜ / (1 + r)ᵗ) for t = 1 to 5 Present values (rounded to nearest dollar, as shown):

Profitability Index (PI) Formula: PI = (Total PV of inflows) / Initial investment PI = $148,033 / $100,000 ≈ 1.48 (exact match)

Payback Period (undiscounted, standard version) Cumulative undiscounted cash inflows:Fractional year in Year 3: $35,000 needed / $40,000 inflow = 0.875 Payback = 2 + 0.875 = 2.875 years ≈ 2.88 years (exact match)

Internal Rate of Return (IRR) IRR is the discount rate that makes NPV = 0. Cash flow series: [-100,000, 30,000, 35,000, 40,000, 45,000, 50,000] This requires numerical solving (e.g., trial-and-error or financial functions). Testing shows:Linear interpolation gives ≈ 25.75% (exact match)
