How Is a Car Loan EMI Calculated Monthly? | Easy Guide for 2025

 

Last week, my friend’s older brother bought a brand-new car — price tag: $48,000. While we were admiring the ride, he casually mentioned, “You know what my monthly EMI is?”

I asked him, “Wait, how do you even calculate EMI for a car loan?”

That question is exactly what this guide will answer — in plain, simple terms.

 What Is EMI?

EMI (Equated Monthly Installment) is the fixed amount you pay each month to repay your car loan. Each EMI consists of two parts:

• Principal – The actual loan amount you borrowed
• Interest – The cost of borrowing that money (charged by the bank or lender)

 Car Loan EMI Formula

Here’s the standard formula used to calculate EMI:

EMI=P×R×(1+R)N(1+R)N−1\text{EMI} = \frac{P \times R \times (1 + R)^N}{(1 + R)^N – 1}

Where:

• P = Loan amount (Principal)
• R = Monthly interest rate (Annual rate ÷ 12 ÷ 100)
• N = Number of months (Loan term in years × 12)

 Example: Calculating EMI for a $45,000 Loan

Let’s say you take:

• Loan amount: $45,000
• Loan term: 5 years (60 months)
• Annual interest rate: 6.5%

Now break it down:

• R = 6.5 / 12 / 100 = 0.00542
• N = 60

Apply the formula:

EMI≈$879/monthEMI ≈ \$879/month

This is your monthly commitment.

 Real-Life Pro Tip

My cousin initially planned to put down $5,000 and was looking at a $879/month EMI.
Then he stretched and put down $8,000 instead — suddenly, his EMI dropped to $810/month.

Pro Tip: A higher down payment = lower EMI.

 Final Takeaway

EMI calculation isn’t hard once you know these three values:

• Loan amount (P)
• Interest rate (R)
• Loan term (N)

Just plug them into the formula — or use an online calculator — and you’ll know exactly what to expect each month.
