Understanding EMI Calculation: A Complete Guide
Equated Monthly Installment (EMI) is a fixed payment amount made by a borrower to a lender at a specified date each calendar month. Equated monthly installments are applied to both interest and principal each month so that over a specified number of years, the loan is paid off in full. Our intelligent EMI calculator above provides an exact breakdown, helping you make informed financial decisions before committing to a home, car, or personal loan.
How is EMI Calculated? (The Universal Formula)
The mathematical formula used by banks and financial institutions in India to calculate EMIs is standard. The formula is:
- P stands for the Principal amount (the original loan amount).
- R stands for the Rate of Interest calculated on a monthly basis. (i.e., Annual Rate / 12 / 100).
- N stands for the Number of monthly installments (Loan tenure in months).
Factors Influencing Your EMI
1. Principal Amount
The total amount you borrow. A higher principal results in a higher EMI, assuming tenure and interest rate remain constant.
2. Interest Rate
Determined by the bank based on repo rates and your credit score. Even a 0.5% reduction can save lakhs over a 20-year period.
3. Loan Tenure
A longer tenure reduces your monthly EMI burden but significantly increases the total interest paid to the bank.
