Refinance Car Calculator
Current Car Loan
Refinance Options
The Refinance Car Calculator is a powerful online tool that helps car owners evaluate how much money they can save by refinancing their existing auto loans.
If your car loan interest rate feels too high, or your monthly payments are straining your budget, refinancing could be the solution. By switching to a new loan with a lower interest rate or a different repayment term, you could reduce your monthly payments and save hundreds (or even thousands) in interest costs.
This calculator instantly computes:
- Your current and new monthly payments
- Total interest paid on both loans
- Total savings or extra costs from refinancing
It’s a simple, free, and accurate way to determine if refinancing your vehicle loan is financially worthwhile — all without affecting your credit score.
⚙️ How the Refinance Car Calculator Works
The calculator compares your existing car loan with a potential refinance loan. It applies standard loan amortization formulas to show payment differences and total costs over time.
The standard monthly payment formula is:
M = P × [r(1 + r)^n] / [(1 + r)^n − 1]
Where:
- M = Monthly payment
- P = Loan principal (remaining balance)
- r = Monthly interest rate (annual rate ÷ 12)
- n = Loan term (in months)
By plugging in your current and new loan details, the calculator reveals:
- The difference in total payments
- Interest savings or increase
- Your break-even point (when savings exceed refinance fees)
It helps you see if refinancing is a smart financial move or not.
🧭 How to Use the Refinance Car Calculator (Step-by-Step)
Step 1️⃣ – Enter Current Loan Details
Start by providing your current loan information:
- Remaining loan balance: The amount you still owe.
- Current interest rate (APR): The annual percentage rate on your current loan.
- Remaining loan term: How many months are left on your loan.
Step 2️⃣ – Enter Refinancing Details
Now, enter the details of your potential refinance loan:
- New interest rate (APR): The rate offered by the new lender.
- New loan term (months): The new repayment duration.
- Refinance fees (optional): Any lender or title transfer fees.
Step 3️⃣ – Click “Calculate”
In seconds, the calculator will display:
- Your current monthly payment
- New monthly payment after refinancing
- Total interest savings
- Break-even point (how long it takes to cover refinance costs)
Step 4️⃣ – Review and Compare
Use the results to decide whether refinancing is beneficial.
If your savings are greater than any fees and your total interest cost decreases, refinancing is a good decision.
📘 Example: Refinancing in Action
Let’s walk through a practical scenario:
Current Loan Details:
- Loan balance: $18,000
- Interest rate: 8% APR
- Remaining term: 48 months
New Refinance Offer:
- New interest rate: 5% APR
- New term: 48 months
Now, let’s calculate:
Current Loan Payment:
M = $439.88/month
Total Interest = $3,114.24
New Loan Payment:
M = $414.72/month
Total Interest = $1,906.56
✅ Monthly Savings: $25.16
✅ Total Interest Savings: $1,207.68
That’s over $1,200 saved across the life of the loan — simply by refinancing at a lower rate.
