TEST CASE: URL013572 - Daud Andrew Chibita
================================================================================

INPUT PARAMETERS:
  Initial Balance (DeductionAmount): 6,397,076.07
  Remaining Balance (DeductionBalance): 4,264,712.07
  Monthly Payment: 177,696.56
  Annual Interest Rate: 12%
  Days Since Last Payment: 7

--- STEP 1: Calculate Original Loan Details ---
  Tenure (months) = Initial Balance / Monthly Payment
  Tenure = 6,397,076.07 / 177,696.56 = 36 months
  Original Principal (using PV formula): 5,350,000.08

--- STEP 2: Calculate Current Outstanding Principal (P) ---
  Payments Made = (Initial Balance - Remaining Balance) / Monthly Payment
  Payments Made = (6,397,076.07 - 4,264,712.07) / 177,696.56
  Payments Made = 12 installments
  Outstanding Principal (P) after 12 payments: 3,774,876.84

--- STEP 3: Apply Dynamic Payoff Formula ---
  Formula: Total Payoff = P + (P × R/365 × D)
  Where:
    P = 3,774,876.84 (Outstanding Principal)
    R = 0.12 (Annual Rate)
    D = 7 (Days Since Last Payment)

  Pro-rated Interest = P × (R/365) × D
  Pro-rated Interest = 3,774,876.84 × (0.12/365) × 7
  Pro-rated Interest = 8,687.39

  Total Payoff Amount = P + Pro-rated Interest
  Total Payoff Amount = 3,774,876.84 + 8,687.39
  TOTAL PAYOFF AMOUNT = 3,783,564.23

  Expected Payoff: 3,783,573.59
  Difference: 9.36
  Status: ✗ FAIL

TEST CASE: Simple Test Loan
================================================================================

INPUT PARAMETERS:
  Initial Balance (DeductionAmount): 1,000,000.00
  Remaining Balance (DeductionBalance): 600,000.00
  Monthly Payment: 50,000.00
  Annual Interest Rate: 10%
  Days Since Last Payment: 15

--- STEP 1: Calculate Original Loan Details ---
  Tenure (months) = Initial Balance / Monthly Payment
  Tenure = 1,000,000.00 / 50,000.00 = 20 months
  Original Principal (using PV formula): 917,600.90

--- STEP 2: Calculate Current Outstanding Principal (P) ---
  Payments Made = (Initial Balance - Remaining Balance) / Monthly Payment
  Payments Made = (1,000,000.00 - 600,000.00) / 50,000.00
  Payments Made = 8 installments
  Outstanding Principal (P) after 8 payments: 568,725.42

--- STEP 3: Apply Dynamic Payoff Formula ---
  Formula: Total Payoff = P + (P × R/365 × D)
  Where:
    P = 568,725.42 (Outstanding Principal)
    R = 0.1 (Annual Rate)
    D = 15 (Days Since Last Payment)

  Pro-rated Interest = P × (R/365) × D
  Pro-rated Interest = 568,725.42 × (0.1/365) × 15
  Pro-rated Interest = 2,337.23

  Total Payoff Amount = P + Pro-rated Interest
  Total Payoff Amount = 568,725.42 + 2,337.23
  TOTAL PAYOFF AMOUNT = 571,062.65

TEST CASE: Nearly Paid Off Loan
================================================================================

INPUT PARAMETERS:
  Initial Balance (DeductionAmount): 500,000.00
  Remaining Balance (DeductionBalance): 50,000.00
  Monthly Payment: 25,000.00
  Annual Interest Rate: 8%
  Days Since Last Payment: 30

--- STEP 1: Calculate Original Loan Details ---
  Tenure (months) = Initial Balance / Monthly Payment
  Tenure = 500,000.00 / 25,000.00 = 20 months
  Original Principal (using PV formula): 466,647.56

--- STEP 2: Calculate Current Outstanding Principal (P) ---
  Payments Made = (Initial Balance - Remaining Balance) / Monthly Payment
  Payments Made = (500,000.00 - 50,000.00) / 25,000.00
  Payments Made = 18 installments
  Outstanding Principal (P) after 18 payments: 49,504.41

--- STEP 3: Apply Dynamic Payoff Formula ---
  Formula: Total Payoff = P + (P × R/365 × D)
  Where:
    P = 49,504.41 (Outstanding Principal)
    R = 0.08 (Annual Rate)
    D = 30 (Days Since Last Payment)

  Pro-rated Interest = P × (R/365) × D
  Pro-rated Interest = 49,504.41 × (0.08/365) × 30
  Pro-rated Interest = 325.51

  Total Payoff Amount = P + Pro-rated Interest
  Total Payoff Amount = 49,504.41 + 325.51
  TOTAL PAYOFF AMOUNT = 49,829.92
