What Is a Loan?
A loan is a financial agreement where a lender (bank or NBFC) provides a lump sum to a borrower, who repays it with interest over an agreed period. The three pillars of any loan are Principal (the amount borrowed), Interest Rate (annual cost of borrowing), and Tenure (repayment period in months or years).What Is EMI?
EMI (Equated Monthly installment) is the fixed monthly payment that combines both principal repayment and interest. The standard formula is:EMI = P × r × (1+r)^n ÷ [(1+r)^n − 1]
Where P = principal, r = monthly interest rate (annual ÷ 12 ÷ 100), n = number of months. Example: For a ₹10,00,000 loan at 9% p.a. for 60 months:
Secured vs. Unsecured Loans
| Feature | Secured | Unsecured |
|---|---|---|
| Collateral | Required (house, car) | Not required |
| Interest rate | Lower (8–12%) | Higher (12–24%) |
| Loan amount | Higher | Lower |
| Examples | Home, Car, Gold loans | Personal, Education |
How to Pick the Right Tenure
A longer tenure lowers the EMI but increases total interest paid. A shorter tenure does the opposite. Use the calculator above to compare scenarios side by side before committing. Rule of thumb: Your total EMI obligations (all active loans) should not exceed 40% of your net monthly income.Processing Fees and Hidden Charges
