Understanding Your EMI Calculator
What is an EMI Calculator?
An EMI (Equated Monthly Installment) calculator is a financial tool that helps you calculate the fixed monthly payment amount you need to pay for any loan. EMI includes both the principal amount and the interest charged on the loan, spread equally over the loan tenure.
How the Calculator Works
The EMI calculator uses a standard mathematical formula to compute your monthly installment. It takes into account:
- Principal loan amount
- Annual interest rate
- Loan tenure in months
The Mathematical Formula
The EMI is calculated using this formula:
EMI = P × r × (1 + r)ⁿ / [(1 + r)ⁿ - 1]
Where:
P = Principal loan amount
r = Monthly interest rate (Annual rate ÷ 12 ÷ 100)
n = Number of monthly installments
This formula ensures that you pay the same amount every month throughout the loan tenure, making budgeting easier.
Key Components Explained
Principal Amount
The total amount you borrow from the lender. This is the base amount on which interest is calculated.
Interest Rate
The annual percentage rate charged by the lender. This is converted to a monthly rate for EMI calculation.
Loan Tenure
The duration over which you'll repay the loan. Longer tenure means lower EMI but higher total interest.
EMI Structure
Initially, a larger portion goes toward interest. Over time, more goes toward principal repayment.
