Module C: Formula & Methodology Behind the Calculator
Our calculator uses the exact reducing balance method that IOB Bank implements, following RBI guidelines for car loan calculations. Here’s the detailed mathematical approach:
1. EMI Calculation Formula
The monthly EMI is calculated using this standard formula:
EMI = [P × R × (1+R)^N] / [(1+R)^N – 1]
Where:
P = Loan amount (principal)
R = Monthly interest rate (annual rate/12/100)
N = Loan tenure in months
2. Monthly Interest Rate Conversion
For an annual rate of 8.5%:
Monthly rate (R) = 8.5/12/100 = 0.007083 (0.7083%)
3. Amortization Schedule Logic
Each EMI payment consists of:
- Interest component = (Remaining principal) × (monthly rate)
- Principal component = EMI – interest component
Example for ₹5,00,000 loan at 8.5% for 3 years:
| Month | Opening Balance | EMI (₹) | Principal (₹) | Interest (₹) | Closing Balance |
|---|---|---|---|---|---|
| 1 | 500,000.00 | 15,622.00 | 12,955.17 | 2,666.83 | 487,044.83 |
| 2 | 487,044.83 | 15,622.00 | 13,022.60 | 2,599.40 | 474,022.23 |
| 3 | 474,022.23 | 15,622.00 | 13,091.09 | 2,530.91 | 460,931.14 |
| … | … | … | … | … | … |
| 36 | 15,599.20 | 15,622.00 | 15,577.20 | 44.80 | 0.00 |
4. Total Interest Calculation
Total Interest = (EMI × Total months) – Principal
For our example: (15,622 × 36) – 500,000 = ₹62,392
5. Processing Fee Calculation
Processing Fee = (Loan Amount) × (Fee Percentage)
For ₹5,00,000 at 1%: ₹5,000
Module D: Real-World Calculation Examples
Case Study 1: Mid-Range Sedan (₹8 Lakh)
- Loan Amount: ₹7,20,000 (90% of ₹8,00,000)
- Interest Rate: 8.75% (standard rate for salaried)
- Tenure: 5 years
- Processing Fee: 1% (₹7,200)
- Results:
- Monthly EMI: ₹14,586
- Total Interest: ₹1,55,160
- Total Amount: ₹8,75,160
- Analysis: While the EMI is affordable at ~15% of monthly income (assuming ₹1,00,000 salary), the total interest paid is 21.5% of the principal. Opting for 4 years would save ₹27,000 in interest with only ₹1,500 higher EMI.
Case Study 2: Compact SUV (₹12 Lakh)
- Loan Amount: ₹10,80,000 (90% of ₹12,00,000)
- Interest Rate: 8.50% (women borrower concession)
- Tenure: 7 years
- Processing Fee: 1% (₹10,800)
- Results:
- Monthly EMI: ₹17,620
- Total Interest: ₹4,23,040
- Total Amount: ₹15,03,040
- Analysis: The 7-year tenure makes the EMI manageable but results in paying 39% of the principal as interest. Reducing tenure to 5 years would save ₹1,40,000 in interest with EMI increasing to ₹21,800.
Case Study 3: Used Car (₹4 Lakh)
- Loan Amount: ₹3,20,000 (80% of ₹4,00,000 valuation)
- Interest Rate: 10.25% (higher rate for used cars)
- Tenure: 3 years
- Processing Fee: 1% (₹3,200)
- Results:
- Monthly EMI: ₹10,425
- Total Interest: ₹51,300
- Total Amount: ₹3,71,300
- Analysis: Used car loans have higher rates but shorter maximum tenures. Here 16% of the principal goes toward interest. Paying 20% down payment reduces the loan amount significantly compared to new cars.

Module G: Interactive FAQ About IOB Car Loan Interest
How does IOB Bank calculate interest on car loans?
IOB Bank uses the reducing balance method (also called diminishing balance) where interest is calculated only on the outstanding principal amount. This is different from the flat rate method some NBFCs use. Here’s how it works:
- Interest for each month = (Remaining principal) × (monthly interest rate)
- Principal repaid = EMI – interest portion
- Remaining principal decreases with each payment
Our calculator replicates this exact method. For example, on a ₹5,00,000 loan at 8.5% for 3 years:
- First month interest: ₹5,00,000 × 0.085/12 = ₹3,541.67
- Principal repaid: ₹15,622 (EMI) – ₹3,541.67 = ₹12,080.33
- New principal: ₹5,00,000 – ₹12,080.33 = ₹4,87,919.67
This continues until the loan is fully repaid. The reducing balance method ensures you pay less total interest compared to flat rate calculations.
What is the current IOB car loan interest rate for 2024?

| Government Employees | 7.90% – 10.00% | 8.90% – 11.00% | 7.50% – 9.50% |
Note: These rates are subject to change based on:

Can I get a car loan from IOB Bank with a low CIBIL score?
IOB Bank typically requires a minimum CIBIL score of 650 for car loan approval, but the interest rate and loan terms depend heavily on your score:
| CIBIL Score Range | Approval Chance | Interest Rate Impact | Max Loan Amount |
|---|---|---|---|
