EMI Calculator (Equated Monthly Installment & Interest)

Calculate fixed equated monthly installments (EMI), total interest, and loan amortization.

TL;DR: EMI Calculator computes the exact monthly installment payable on personal, home, or auto loans using standard reducing-balance amortization formulas.

What Is an Equated Monthly Installment (EMI) and How Is It Calculated?

An Equated Monthly Installment (EMI) is a fixed payment amount made by a borrower to a lender at a specified date each calendar month. EMI is calculated using the formula: EMI = P × r × (1 + r)^n / [(1 + r)^n - 1], where P is principal, r is monthly interest rate, and n is tenure in months.

How to Use the EMI Calculator

Our EMI Calculator performs high-precision mathematical operations directly in your browser with zero latency and complete client-side privacy.

  1. Enter the Loan Principal Amount ($P$).
  2. Input the Annual Interest Rate percentage ($R$).
  3. Specify Loan Tenure in Years or Months ($N$).
  4. Click 'Calculate EMI' to view monthly installment and total payment breakdown.
  5. Inspect the graphical pie chart showing Principal versus Total Interest.

Mathematical Formula & Equations

Where P is principal amount, r is monthly interest rate, and n is tenure in months.

\[ \text{EMI} = P \times r \times \frac{(1 + r)^n}{(1 + r)^n - 1} \]

Calculation Example

For an Equated Monthly Installment on ₹1,000,000 at 9% per annum for 10 years (120 months): $$\text{EMI} = 1000000 \times 0.0075 \times \frac{(1.0075)^{120}}{(1.0075)^{120} - 1} = ₹12,667.58$$

Frequently Asked Questions

The mathematical formula is `EMI = P × r × (1 + r)^n / [(1 + r)^n - 1]`, where `P` is principal, `r` is monthly interest rate (`Annual Rate / 12 / 100`), and `n` is loan tenure in months.
A flat rate calculates interest on the full original principal for the entire loan life. A reducing balance rate recalculates interest only on the remaining outstanding principal, making it substantially cheaper.
You can lower your EMI by increasing your down payment, negotiating a lower interest rate, or extending your loan tenure (which reduces EMI but increases total interest).
Prepayment is paying a lump sum toward your loan principal early, which reduces the remaining tenure or lowers subsequent monthly EMIs.
In many jurisdictions, the interest component of home loan EMIs and educational loans offers substantial annual income tax deductions.
Yes. The mathematical EMI formula operates purely on numerical principal, percentage rate, and periods regardless of currency symbol.
