Outstanding Principal Calculation

For each month elapsed:
  Interest = Balance × (Rate / 12 / 100)
  Principal = EMI - Interest
  Balance = Balance - Principal

2. Calculate rate differential (investment vs loan)
3. Determine base prepayment ratio
4. Adjust for loan stage (early/mid/final)
5. Adjust for retirement proximity
6. Calculate optimal mix (monthly/yearly/lumpsum)
7. Generate confidence score

Interest Savings

Baseline Interest = Total interest without prepayment
Prepayment Interest = Total interest with prepayment
Savings = Baseline - Prepayment
