Your personal loan EMI depends on three things: the amount, the interest rate and the tenure. Your CIBIL score mostly affects the rate — a strong score can mean a rate several percentage points lower — while a longer tenure lowers the EMI but increases total interest. On a ₹5 lakh loan for 5 years, the difference between an 11% and a 16% rate is about ₹1,300 a month and ₹77,000 in total interest.
How personal loan EMI is calculated
Banks and NBFCs use the standard reducing-balance formula: EMI = P × r × (1 + r)^n / ((1 + r)^n − 1), where P is the loan amount, r is the monthly interest rate (annual rate ÷ 12 ÷ 100) and n is the number of monthly instalments. Early EMIs are mostly interest; later EMIs are mostly principal.
Personal loans are unsecured, so rates are higher than home or car loans. Depending on the lender, your income, employer and credit history, offers commonly range from around 10.5% to well above 20% a year. Rates change with market conditions, so always check current offers.
How your CIBIL score affects the rate
A credit score (CIBIL or another bureau's) runs from 300 to 900 and summarises how reliably you have repaid credit. Lenders use it to decide whether to lend and at what price. Each lender has its own pricing grid, but the pattern is consistent: higher scores get lower rates and better terms, and scores below about 700 may face rejection or much higher rates.
What goes into the score:
- Repayment history — late EMIs or credit-card payments hurt the most.
- Credit utilisation — using a large share of your card limits signals stress.
- Credit mix and age — a long, well-handled history helps.
- Recent enquiries — many loan applications in a short time can lower the score.
Worked example: ₹5 lakh at different rates
The figures below are illustrations, not quotes from any lender. They show what a ₹5 lakh loan costs at rates a borrower might see across the credit-score spectrum.
- 11%: 3 years — EMI ₹16,370, total interest ₹89,300 · 5 years — EMI ₹10,870, total interest ₹1.52 lakh
- 13%: 3 years — EMI ₹16,850, total interest ₹1.06 lakh · 5 years — EMI ₹11,380, total interest ₹1.83 lakh
- 16%: 3 years — EMI ₹17,580, total interest ₹1.33 lakh · 5 years — EMI ₹12,160, total interest ₹2.30 lakh
- 20%: 3 years — EMI ₹18,580, total interest ₹1.69 lakh · 5 years — EMI ₹13,250, total interest ₹2.95 lakh
- 24%: 3 years — EMI ₹19,620, total interest ₹2.06 lakh · 5 years — EMI ₹14,380, total interest ₹3.63 lakh
Two lessons stand out. First, moving from 11% to 20% almost doubles total interest over 5 years. Second, at any rate, the 5-year option costs far more in total than the 3-year one even though its EMI is lower.
Choosing the right tenure
A longer tenure is tempting because the EMI drops sharply — at 14%, a ₹5 lakh loan costs about ₹17,090 a month over 3 years but only ₹11,630 over 5 years. The catch: total interest rises from about ₹1.15 lakh to about ₹1.98 lakh.
A sensible approach is to pick the shortest tenure whose EMI fits comfortably within your budget, keeping total EMIs (all loans together) well under half of your take-home pay. If you expect bonuses, check the lender's foreclosure and part-prepayment terms — some personal loans charge a fee for early closure, typically a few percent of the outstanding amount, and some allow it free after a minimum number of EMIs.
Costs beyond the interest rate
- Processing fee: often 1%–3% of the loan amount plus GST, deducted upfront from the disbursal.
- Insurance add-ons: sometimes bundled; ask whether they are optional.
- Late-payment charges and bounce fees: they add up quickly and damage your score.
- Foreclosure charges: as above.
Compare offers on total cost — EMI × number of months plus fees — rather than on the headline rate alone. The Key Fact Statement that regulated lenders must share lists the annual percentage rate including fees.
How to get a lower personal loan rate
- Check your credit report for errors and dispute them before applying.
- Pay all cards and EMIs on time for several months, and bring card utilisation down.
- Avoid applying with many lenders at once; compare pre-approved offers first.
- Start with your salary-account bank, which already knows your income pattern.
- Borrow only what you need — a smaller loan with a shorter tenure is easier to repay.
Is a personal loan the right tool?
Personal loans are expensive compared to secured borrowing. For planned expenses, saving in advance through an RD or a small SIP is cheaper. If you own gold or have a fixed deposit, a loan against those may carry a lower rate. Before borrowing, check how the EMI fits your monthly plan in the Budget calculator and how much lenders may sanction in the Loan Eligibility calculator.
