When you take a car loan, you don’t pay everything at once—you repay it in fixed monthly installments called EMI (Equated Monthly Installment). Understanding how EMI is calculated helps you avoid overpaying and choose smarter loan terms.

What Is Car Loan EMI?
A car loan EMI is the fixed amount you pay every month to repay your loan. It includes:
- Principal (loan amount you borrowed)
- Interest (cost of borrowing)
Even though EMI stays constant, the ratio changes over time:
- Early months → more interest, less principal
- Later months → more principal, less interest (DMI Finance)
EMI Calculation Formula
The standard formula used by banks is:
EMI = \frac{P \times r \times (1+r)^n}{(1+r)^n – 1}
Variables Explained
| Symbol | Meaning |
|---|---|
| P | Loan amount (principal) |
| r | Monthly interest rate (annual ÷ 12 ÷ 100) |
| n | Loan tenure in months |
| EMI | Monthly payment |
This formula is used globally by banks and NBFCs for loans like car, home, and personal loans (FinCalcPro)
Step-by-Step Car EMI Calculation
Let’s break it down with an example:
Example:
- Loan Amount = ৳5,00,000
- Interest Rate = 10% annually
- Tenure = 5 years (60 months)
Step 1: Convert Interest Rate
Monthly rate (r) = 10 ÷ 12 ÷ 100 = 0.00833
Step 2: Calculate Tenure
n = 5 × 12 = 60 months
Step 3: Apply Formula
EMI ≈ ৳10,624 (approx.)
Quick EMI Calculation Table
| Loan Amount | Interest Rate | Tenure | EMI (Approx.) |
|---|---|---|---|
| ৳5,00,000 | 10% | 5 years | ৳10,624 |
| ৳10,00,000 | 10% | 5 years | ৳21,247 |
| ৳5,00,000 | 8% | 5 years | ৳10,138 |
| ৳5,00,000 | 10% | 3 years | ৳16,134 |
👉 Even a small interest change can significantly affect EMI.
Key Factors That Affect Car EMI
1. Loan Amount (Principal)
- Higher loan → higher EMI
- Lower down payment → higher EMI
2. Interest Rate
- Even 1% increase can noticeably raise EMI
- Depends on bank, credit score, and market
3. Loan Tenure
- Longer tenure → lower EMI but higher total interest
- Shorter tenure → higher EMI but less total cost
Reducing Balance Method (Most Important Concept)
Car loan EMI is usually calculated using the reducing balance method.
How It Works:
- Interest is charged only on remaining loan balance
- As you repay, interest decreases each month (DMI Finance)
Example Breakdown
| Month | EMI | Interest | Principal | Balance |
|---|---|---|---|---|
| 1 | ৳10,624 | High | Low | High |
| 30 | ৳10,624 | Medium | Medium | Medium |
| 60 | ৳10,624 | Low | High | Zero |
Flat Rate vs Reducing Rate EMI
| Feature | Flat Rate | Reducing Rate |
|---|---|---|
| Interest charged on | Full loan | Remaining balance |
| EMI cost | Higher | Lower |
| Used by | Some lenders | Most banks |
| Transparency | Lower | Higher |
👉 Always choose reducing balance EMI—it’s more cost-efficient.
How to Calculate Car EMI in Excel
You can calculate EMI easily using Excel:
Formula:
=PMT(rate/12, tenure_in_months, -loan_amount)
Example:
=PMT(10%/12, 60, -500000)
This will return your EMI instantly.
