EMI, or Equated Monthly Installment, is the fixed amount you pay every month toward a loan until it is fully repaid. Each EMI is a mix of principal repayment and interest, calculated using the reducing balance method used by most banks and lenders.
EMI = P × r × (1+r)n / ((1+r)n − 1), where P is the principal loan amount, r is the monthly interest rate (annual rate ÷ 12 ÷ 100), and n is the number of monthly installments. For example, a loan of ₹5,00,000 at 8.5% annual interest over 5 years (60 months) works out to a monthly EMI of approximately ₹10,258.
In the reducing balance method, interest is calculated only on the outstanding loan balance. Early EMIs have a larger interest component because the outstanding principal is highest at the start. As you keep paying, the outstanding principal shrinks, so a larger share of each later EMI goes toward principal repayment.
Choosing a shorter tenure, making prepayments when possible, and negotiating a lower interest rate can all significantly reduce the total interest you pay over the life of a loan, even if the EMI itself is slightly higher.
EMI is calculated using the formula EMI = P × r × (1+r)^n / ((1+r)^n − 1), where P is the principal loan amount, r is the monthly interest rate (annual rate divided by 12 and by 100), and n is the total number of monthly installments.
This calculator uses the reducing balance method, the standard method used by banks, where interest is charged only on the outstanding principal each month. As you pay EMIs, the principal reduces and so does the interest portion of each subsequent installment, while a flat rate calculates interest on the full original principal throughout the tenure.
No. This calculator estimates EMI, total interest, and total payable based purely on principal, interest rate, and tenure. Actual loan costs may include processing fees, insurance, prepayment charges, or other lender-specific costs not reflected here.
