The Loan EMI Calculation Formula
EMI calculations use standard reducing balance math. The monthly interest rate (r) is derived from the annual rate (A) using r = A ÷ (12 × 100).
Reducing Balance Amortization Formula
E = P × r × (1 + r)^n ÷ ((1 + r)^n − 1)
Where:
E = Equated Monthly Installment (EMI)
P = Principal Loan Amount
r = Monthly Interest Rate (decimal)
n = Term Duration (number of months)
Example: P = ₹10,00,000, Annual Rate = 10% (r ≈ 0.008333), n = 24
E = 1000000 × 0.008333 × (1.008333)^24 ÷ ((1.008333)^24 − 1) = ₹46,145

How EMI Mechanics Work
An Equated Monthly Installment (EMI) provides a uniform monthly payment schedule designed to clear the entire principal and interest balances concurrently by the end of the term. The formula determines the exact fixed cash flow needed each month to pay down accumulated monthly interest while systematically shrinking principal balances to zero.
Why Early Payments Are Mostly Interest
Interest charges calculate strictly against the remaining loan balance. Because principal balances are highest at inception, early monthly installments consist mainly of interest fees, with a smaller fraction allocated toward debt reduction. As monthly principal drops, accrued interest fees shrink, allowing a progressively larger share of each installment to reduce the remaining principal. This is why prepaying early in the loan term saves more interest than prepaying later.
Flat Rate vs Reducing Balance Interest
There are two common ways lenders calculate interest on a loan:
- Reducing Balance: Interest is charged only on the remaining outstanding balance. This is the most common method used by Indian banks and the one used in this calculator.
- Flat Rate: Interest is charged on the original principal amount for the entire loan term, regardless of how much you've repaid. This usually makes flat rate loans significantly more expensive.

Why is interest higher in early payments?
Interest is charged on the outstanding balance. Because the balance is largest at the beginning, early payments consist mostly of interest and later payments mostly of principal.
Does a longer loan term reduce total cost?
No. A longer term reduces your monthly payment amount, but significantly increases the total interest paid over the life of the loan.
What is reducing balance interest?
Reducing balance interest calculates monthly interest charges strictly on the remaining unpaid principal balance rather than the original starting loan amount.
Can I prepay my loan to reduce interest?
Yes. Prepaying a portion of your loan reduces the outstanding principal, which in turn reduces the interest charged in subsequent months.
How much EMI can I afford?
A common rule of thumb in India is that your total monthly EMI payments should not exceed 40–50% of your net monthly income.
