DECISION MODELINGSENSITIVITY ANALYSIS

Sensitivity Analysis

Evaluate how variations in key operational drivers impact Monthly EMI Payment.

Simulates floating interest rate benchmark hikes or lender discounts.
Calculate the base model above to view scenario sensitivity rows.

Formula & Methodology

EMI = (Principal * r * (1 + r)^n) / ((1 + r)^n - 1)
P
Loan Principal

Total borrowed loan amount.

r
Monthly Interest Rate

Annual interest rate ÷ 12 ÷ 100.

n
Tenure (Months)

Loan 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.

01.Monthly interest rate = 8.75% / 12 = 0.72917% per month.
02.EMI = [25,00,000 × 0.0072917 × (1.0072917)^240] / [(1.0072917)^240 − 1].
03.Monthly EMI = Rs 22,093.
04.Total Repayment = 240 × Rs 22,093 = Rs 53,02,320.
05.Total Interest = Rs 53,02,320 − Rs 25,00,000 = Rs 28,02,320.
Rs 22,093 / MonthOver a 20-year loan, total interest payable often exceeds the original principal borrowed.

Interpretation & Industry Benchmarks

EMI calculation operates on a reducing balance system, where early installments primarily cover interest and later installments reduce principal.

Interest < 40% of TotalShort Tenure

Tenure under 10 years minimizes total interest expense.

Interest > 50% of TotalLong Tenure

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.

Frequently Asked Questions

What factors determine loan EMI?

Loan principal amount, annual interest rate, and tenure duration.

How can I reduce my total interest cost?

Opt for a shorter tenure, make partial prepayments toward the principal, or refinance to a lower interest rate.
