đźš— What is Car Refinancing?
Car refinancing means replacing your current auto loan with a new one, ideally with better terms—such as a lower interest rate, longer repayment term, or both. This can reduce your monthly payment, help you save on interest, or make your budget more manageable.
Common Reasons to Refinance a Car Loan:
- You improved your credit score
- Market interest rates have dropped
- Your current loan has unfavorable terms
- You want to reduce your monthly payment
- You want to pay off your loan faster
🔧 How to Use the Car Refinancing Calculator
Using this calculator is simple. Here's how it works step by step:
1. Enter Your Current Loan Details
- Current Loan Balance ($): The amount you still owe.
- Current Interest Rate (%): The annual interest rate of your current loan.
- Remaining Months: How many months are left on your loan.
2. Enter Refinancing Details
- New Interest Rate (%): The interest rate offered by the new lender.
- New Loan Term (months): Duration of the new loan.
- Refinancing Fees ($): Any costs like application, title transfer, or origination fees.
3. Click "Calculate"
The calculator will display:

- New term: 48 months
- Refinancing fees: $200

- Monthly Savings: $153.91

🛠️ How the Calculator Works (In Simple Terms)
The core of the calculator is based on a standard loan amortization formula:
iniCopyEditM = P × (r × (1 + r)^n) / ((1 + r)^n – 1) Where:
- M = monthly payment
- P = principal (loan amount)
- r = monthly interest rate
- n = number of months
It also calculates:
- Total repayment = M Ă— n
- Total interest = Total repayment - principal
- Savings = Difference between old and new interest
- Break-even = Refinancing fees Ă· monthly savings
