EMI Calculator Guide 2026 — Everything About Loan EMIs
Before taking any loan in India — home, car, or personal — you must calculate your EMI. This guide explains the EMI formula, how banks calculate interest, and how to use HQCalc's EMI calculator to find the best loan structure for your budget.
What is EMI?
EMI (Equated Monthly Installment) is the fixed amount you pay your bank every month to repay a loan. Each EMI has two parts: interest (cost of borrowing) and principal (loan repayment). In early months, most of the EMI goes toward interest. Gradually, more goes toward principal repayment.
The EMI Formula
P = Principal loan amount, R = Monthly interest rate (Annual rate ÷ 12 ÷ 100), N = Loan tenure in months.
Example: ₹50 Lakh Home Loan
Principal: ₹50,00,000 | Rate: 8.5% p.a. | Tenure: 20 years (240 months)
Monthly EMI: ₹43,391 | Total amount paid: ₹1,04,13,840 | Total interest: ₹54,13,840
You'll pay more in interest than your principal over 20 years — this is why prepayments are so powerful.
