Mathematical Formula & Standards

Reducing-balance loan calculations reduce the interest payload as the principal is repaid. The mathematical formula for calculating EMI is:

EMI = P * r * ((1 + r)^n / (1 + r)^n - 1)

Where:

• P = Principal loan amount.
• r = Monthly interest rate (Annual Rate / 12 / 100).
• n = Total number of monthly installments (Years * 12).

Every month, the interest is calculated on the remaining principal balance. The rest of your EMI payment goes toward reducing the principal balance, causing the interest share of your payment to shrink each month.

Equated Monthly Installment (EMI) Calculator Online

Say you're financing a ₹25 lakh property over 20 years at 8.5% annual interest. Plug that in and you'll see the EMI lands around ₹21,700 a month — but the more useful number is what the amortization table shows next to it: in year one you're paying roughly ₹19,900 in interest and only ₹1,700 toward the actual loan balance. That ratio doesn't flip until around year 13. If you've ever wondered why prepaying early makes such a disproportionate difference, that's the mechanism — and this calculator's 'extra payment' field lets you see exactly how many months it shaves off if you add even ₹2,000 a month starting now.

• Calculated EMI Mismatches Bank Quote: The bank uses daily compounding intervals or includes insurance fees. Add these fees to your principal input to match the quote.
• Amortization Grid is Empty: Ensure the loan tenure is set to a value greater than zero.

What is a reducing-balance loan?

In a reducing-balance loan, interest is calculated on the remaining principal balance at the end of each month. As you pay down the principal, the interest share of your monthly payment shrinks.

How do extra prepayments affect my loan?

Prepayments directly reduce the principal balance, which shortens the remaining loan tenure and saves you money on total interest.
