How Home Loan EMI Is Calculated

Use this guide to understand the EMI formula, how interest affects your outflow, and how tenure changes your monthly installment.

Formula

EMI = P x r x (1 + r)^n / ((1 + r)^n - 1), where P is principal, r is monthly interest rate, and n is total months.

Example Calculation

  • Loan Amount: Rs 1.00 Cr
  • Interest Rate: 8.5% per year
  • Tenure: 20 years (240 months)

Estimated EMI: around Rs 86,782 per month

Investment Insights

  • Longer tenure lowers EMI but increases total interest paid.
  • A small rate change has a large impact on long-tenure loans.
  • Prepaying principal early can significantly reduce interest burden.
