An EMI (Equated Monthly Instalment) is the fixed monthly payment made by a borrower to a lender to repay a loan over a specified tenure. The EMI consists of two components: the principal repayment and the interest payment. In the reducing balance method (used by all Indian banks for personal and home loans), the EMI is fixed, but the interest component decreases each month as the outstanding principal reduces, while the principal component increases correspondingly. This differs from the flat rate method (used historically in some personal loans) where interest is charged on the original principal for the entire tenure. Indian banks use the reducing balance EMI formula universally. Personal loan interest rates in India range from 10.5% to 24% per annum depending on the borrower's credit score, income level, and the lender. Bank personal loans typically offer 10.5-15%; NBFCs charge 14-24%. Understanding EMI calculation helps in comparing loan offers, planning prepayment, evaluating balance transfers, and building an amortisation schedule to understand the interest vs principal split each month.
EMI = P × r × (1+r)^n / [(1+r)^n - 1] | Total Interest = (EMI × n) - P | Interest Component (month m) = Outstanding Balance × monthly rate
- 1Determine the loan principal (P), annual interest rate, and tenure in months (n).
- 2Convert annual rate to monthly: r = annual rate / 12 / 100.
- 3Apply EMI formula: EMI = P × r × (1+r)^n / [(1+r)^n - 1].
- 4Compute total interest paid: Total Interest = (EMI × n) - P.
- 5Build amortisation schedule: for each month, interest = outstanding balance × r; principal = EMI - interest; new outstanding = old outstanding - principal paid.
- 6Evaluate prepayment: if you make an extra payment, the outstanding balance reduces; future interest savings can be computed by projecting the revised amortisation schedule.
- 7Compare balance transfer: new EMI on remaining principal at a lower rate; compute breakeven considering processing fee to determine if balance transfer is worthwhile.
Interest = 19.6% of principal over 3 years; effective cost depends on creditworthiness
r = 12/12/100 = 0.01. EMI = 5L × 0.01 × (1.01)^36 / [(1.01)^36 - 1] = 5L × 0.01 × 1.4308 / 0.4308 = 5L × 0.03321 = ₹16,607. Total payment = 16,607 × 36 = ₹5,97,852. Interest = ₹97,852.
Interest reduces each month; principal repayment accelerates as balance decreases
EMI = 3L × (0.0125) × (1.0125)^24 / [(1.0125)^24 - 1] = ₹14,534. Month 1 interest = 3L × 1.25% = ₹3,750. Principal = 14,534 - 3,750 = ₹10,784. Month 2 balance = 2,89,216; interest = 2.89L × 1.25% = ₹3,615. Gradual shift from interest to principal over tenure.
Prepayment in early months saves more interest due to higher outstanding principal
After 12 months, outstanding ≈ ₹8.65L. Prepaying ₹2L reduces it to ₹6.65L. Revised amortisation at 13% on ₹6.65L for remaining ~48 months reduces total interest by ~₹72,000. Alternatively, can reduce EMI with same 48 months.
Balance transfer worthwhile; breaks even in ~11 months; all savings accrue after breakeven
Old EMI at 14% on ₹4L for 24 months = ₹19,244; total interest = ₹62,856. New EMI at 11% = ₹18,561; total interest = ₹45,464. Interest saving = ₹17,392 net of transfer fee ₹6,000 = ₹11,392. Even after processing fee, balance transfer saves significantly over 24 months.

What is the difference between reducing balance and flat rate EMI?
In the reducing balance method (used by all major Indian banks), EMI stays fixed but interest decreases each month as the outstanding principal reduces. In the flat rate method (used by some older loan products and informal lenders), interest is calculated on the original principal for the entire tenure — making it significantly more expensive than it appears. A flat rate of 12% is equivalent to an effective reducing balance rate of approximately 21.4% for a 3-year loan.
How does prepayment work for personal loans?
Prepayment allows you to pay an extra amount over and above your regular EMI, reducing the outstanding principal. You can then choose to: keep EMI the same and reduce tenure (saves more interest — recommended), or keep tenure the same and reduce EMI. Prepayment in the early months of a loan saves maximum interest. Most personal loans in India allow prepayment after 6-12 months without charges; check your loan terms for foreclosure charges.
What CIBIL score is needed for a personal loan at the best rates?
CIBIL score 750+ typically qualifies for personal loans at the best rates (10.5-12% from top banks). Score 700-749: 12-15%; Score 650-699: 15-20%; Below 650: very difficult to get bank loans; NBFC rates 20-36%. Improving your CIBIL score (by repaying all existing EMIs on time) before applying for a personal loan can save significantly on interest.
Is personal loan interest tax-deductible in India?
Personal loan interest is generally NOT tax-deductible. Exceptions: if the personal loan is used for purchasing or constructing a house, the interest can be deducted under Section 24(b) (up to ₹2 lakh for self-occupied property). If the loan is used to buy investment property, interest is fully deductible against rental income. Business loans: interest deductible against business income. Keep records of how personal loan funds are used if claiming deductions.
What is a loan against property (LAP) and how is it different from a personal loan?
Loan Against Property (LAP) is secured by mortgaging a property — interest rates are 8.5-12% (significantly lower than personal loan at 10.5-24%) and tenure can be up to 15-20 years (vs 5 years for personal loans). LAP can provide larger amounts (up to 60-70% of property value). The risk: defaulting on LAP can result in loss of the mortgaged property, unlike personal loans which are unsecured.
How is EMI affected if interest rate changes during the loan?
For floating rate personal loans (rare — most personal loans have fixed rates), an interest rate change affects either the EMI or the tenure. Banks typically keep EMI fixed and adjust tenure. If rates rise, the tenure increases; if rates fall, it decreases. For fixed rate personal loans (most common), the EMI and tenure remain unchanged for the loan duration regardless of RBI rate changes.
What is the effective cost of a personal loan with processing fee?
Processing fees (1-3% of loan amount + GST) increase the effective APR. For a ₹5L loan at 12% for 3 years with 2% processing fee: processing fee = ₹10,000. You receive ₹4,90,000 but pay EMI on ₹5,00,000. The effective APR = slightly higher than 12% — use the IRR formula or an online calculator to compute the true all-in cost including the processing fee.
Should I take a personal loan or use credit card EMI for a large purchase?
Personal loans at 10.5-15% APR are almost always cheaper than credit card EMIs at 18-42% APR. The trade-off: personal loan requires a separate application, credit check, and income verification (2-5 day process); credit card EMI is instant but costlier. For purchases above ₹50,000 with tenure above 6 months, a personal loan is almost always the better financial choice.
Pro Tip
For any personal loan above ₹2 lakh, negotiate the interest rate — even 0.5% lower on a ₹5L loan for 3 years saves ₹1,500 in total interest. Your credit score, existing banking relationship, and competing offer from another bank are your strongest negotiation tools. Show the competing offer in writing.
