Step-by-Step Example Calculation
See the calculation in action. Below is a step-by-step mathematical example using default parameters to demonstrate how values are processed and generated.
Standard Default Simulation (Step-by-Step)
01Step 1
Initialize all calculator inputs with their official default values: Loan Amount (P) = 1000000₹, Annual Interest Rate (% p.a.) = 8.5%, Loan Tenure (Years) = 15yrs.
02Step 2
The engine compiles the parameters and triggers the formulas in the calculation library.
03Step 3
Under this standard setup, the calculator yields: Monthly EMI Payable: 0, Total Interest Payable: 0, Total Amount Payable (P + I): 0.

Frequently Asked Questions
EMI is calculated using: EMI = [P × R × (1 + R)^N] / [(1 + R)^N - 1], where P is principal loan amount, R is monthly interest rate (annual rate ÷ 12 ÷ 100), and N is loan tenure in months.
In a reducing balance loan, interest is calculated only on the remaining unpaid principal each month, reducing total interest cost. In a flat rate loan, interest is calculated on the full initial loan amount throughout the tenure, making flat rates significantly more expensive.
Making principal prepayments directly reduces your outstanding loan balance. You can choose to either shorten your loan tenure (saving significant interest) or lower your monthly EMI amount.

EMI Reducing Balance Formula Explained
Equated Monthly Installments (EMIs) are calculated using the reducing balance method formula: EMI = [P × R × (1 + R)^N] / [(1 + R)^N - 1], where P is Principal, R is monthly interest rate (Annual Rate / 12 / 100), and N is loan tenure in months (Years × 12).
In early loan years, a major portion of each EMI goes toward paying interest, while a smaller portion reduces principal. As the outstanding principal drops over time, the interest component decreases and the principal repayment component increases.
Worked Loan EMI Examples
Example 1: ₹10,000,000 Home Loan at 8.5% for 15 Years (180 months)
- Monthly Rate R = 8.5 / 12 / 100 = 0.007083; Months N = 180.
- Calculate EMI = [10,00,000 × 0.007083 × (1.007083)^180] / [(1.007083)^180 - 1] = ₹9,847.
- Total Repayment = ₹9,847 × 180 = ₹17,72,537.
Monthly EMI: ₹9,847 | Total Interest: ₹7,72,537 | Total Payment: ₹17,72,537.
Frequently Asked Questions About Loan EMIs
What is the mathematical formula for loan EMI calculation?
EMI is calculated using: EMI = [P × R × (1 + R)^N] / [(1 + R)^N - 1], where P is principal loan amount, R is monthly interest rate (annual rate ÷ 12 ÷ 100), and N is loan tenure in months.
What is the difference between reducing balance and flat interest rate EMI?
In a reducing balance loan, interest is calculated only on the remaining unpaid principal each month, reducing total interest cost. In a flat rate loan, interest is calculated on the full initial loan amount throughout the tenure, making flat rates significantly more expensive.
How does loan prepaying affect your total EMI interest cost?
Making principal prepayments directly reduces your outstanding loan balance. You can choose to either shorten your loan tenure (saving significant interest) or lower your monthly EMI amount.
