Formula & Methodology
EMI = (Principal * r * (1 + r)^n) / ((1 + r)^n - 1)PTotal borrowed loan amount.
rAnnual interest rate ÷ 12 ÷ 100.
nLoan duration in months (Years × 12).
Practical Worked Example
A borrower takes a Rs 25,00,000 home loan at 8.75% annual interest for a 20-year tenure.
Interpretation & Industry Benchmarks
EMI calculation operates on a reducing balance system, where early installments primarily cover interest and later installments reduce principal.
Tenure under 10 years minimizes total interest expense.
Tenure 20–30 years lowers monthly EMI but significantly increases total interest cost.
Industry Nuance: Making one extra EMI prepayment per year can reduce a 20-year mortgage tenure by more than 4 years.
Analytical Limitations
- Assumes a fixed interest rate throughout tenure; does not model floating rate adjustments.
