Personal loan: what you borrow and what you repay
A personal loan is unsecured: nothing is pledged, so the lender prices its risk into the rate and decides mainly on your income and your credit report. You receive a lump sum, minus any fee, and repay it in equal monthly instalments over a fixed term, usually one to five years. Most personal loans in India are fixed-rate, so the EMI stays the same for the life of the loan.
The EMI is computed on a reducing balance: each month, interest is charged only on what you still owe, and the rest of the EMI repays principal. The formula is EMI = P × i × (1 + i)^n ÷ ((1 + i)^n − 1), where P is the amount borrowed, i is the annual rate divided by 12 and then by 100, and n is the number of months. Take ₹3 lakh over 36 months at an illustrative 12 percent. Here i is 0.01 and the EMI is ₹9,964. Over three years you repay ₹3,58,715, of which ₹58,715 is interest: 19.6 percent of what you borrowed.
- Month 1: interest / principal
- ₹3,000 / ₹6,964
- Month 36: interest / principal
- ₹99 / ₹9,866
- Interest paid in year 1
- ₹31,247
- Interest paid in year 2
- ₹20,045
- Interest paid in year 3

- Total interest
- ₹58,715
Reducing-balance EMI of ₹9,964, no fee. Month-1 interest is 1% of ₹3,00,000; each later month's interest is 1% of the balance left.
- Interest is front-loaded: ₹31,247 of the ₹58,715, or 53.2 percent, is paid in the first twelve months. Closing a loan in its last year saves little; closing it in its first year saves most
- A flat-rate quote is a different number. 7 percent flat on ₹3 lakh over 36 months charges interest on the full ₹3 lakh every year, ₹63,000 in total, for an EMI of ₹10,083. On a reducing balance that is 12.83 percent, so 7 percent flat costs more than 12 percent reducing
