Standard Equated Monthly Installment (EMI) Formula

Calculates monthly loan repayment installments and interest amortization using the standard mathematical reducing-balance formula used by all Indian banks.

EMI = [P * r * (1 + r)^n] / [(1 + r)^n - 1] (where P = Principal, r = Monthly Interest Rate, n = Tenure in Months)

Calculation Steps

  • 1Convert annual interest rate to monthly rate: r = (Annual Rate / 12) / 100.
  • 2Convert loan tenure in years to total months: n = Years * 12.
  • 3Compute (1 + r)^n factor.
  • 4Multiply by principal and evaluate numerator / denominator ratio to find monthly EMI.
  • 5Compute Total Interest = (EMI * n) - Principal.

Practical Example

Scenario: Education or Home Loan of ₹20,00,000 at 9.5% interest for 10 years (120 months)

Inputs: Principal: ₹20,00,000 | Interest: 9.5% p.a. | Tenure: 10 Years (120 Months)

Calculation: r = 0.095/12 = 0.007917 | EMI = [2000000 * 0.007917 * (1.007917)^120] / [(1.007917)^120 - 1] = ₹25,873

Result: Monthly EMI: ₹25,873 | Total Interest: ₹11,04,749 | Total Repayment: ₹31,04,749

Assumptions & Disclaimers

Key Assumptions:

  • Interest is compounded monthly on a reducing balance basis.
  • Fixed interest rate throughout loan tenure.

Does not include bank processing fees, documentation charges, stamp duty, or pre-payment penalties. Floating interest rates may adjust EMI or tenure over time.

Frequently Asked Questions

In a reducing balance loan, interest is charged only on the outstanding principal balance each month rather than the initial principal, decreasing total interest paid.
