Car Loan Refinancing: What to Compare Before You Decide

Start with the remaining balance and remaining months

Refinancing replaces the current debt with new financing. Write down the current payout balance, current APR, monthly payment and months left. Then compare the proposed loan using the same remaining balance rather than comparing it with the original purchase price.

A lower payment is not automatically a saving

A lender can lower the payment by extending the debt over more months. That may improve cash flow while increasing how long you stay in debt. Compare the total remaining payments and any fees, not just the monthly number.

Include every refinancing cost

Ask about application, discharge, registration or other charges that may apply. The names and amounts vary by lender and jurisdiction. A small rate reduction can be cancelled out by fees when the remaining balance is low or the remaining term is short.

Check the new term against the age of the car

A very long loan on an older vehicle can leave you making payments while repair needs increase. Consider whether the new payoff date still makes sense for how long you expect to keep the vehicle.

Read the agreement before replacing the loan

FCAC recommends reviewing interest rates, fees and repayment terms before signing borrowing agreements. Use the contract numbers for the final comparison.

Avoid restarting the clock without noticing

A common refinancing trap is taking a balance that had three years left and stretching it into a new five- or six-year loan. The payment can fall dramatically even when the lifetime saving is small. Compare the new payoff date with the old one. If cash-flow relief is the reason for refinancing, that can still be a valid goal, but treat it as a cash-flow decision rather than automatically calling it an interest-saving decision.

Calculate the break-even point

Add the fees required to refinance, then estimate the monthly interest or payment savings from the new loan. The fees divided by the monthly savings gives a rough break-even period. If you expect to sell or pay off the car before that point, the refinance may not create the saving you expected. This is only a screening calculation because loan amortization changes over time, but it is useful before you spend time on a full application.

Questions people often ask

When can refinancing help?

It may help when the new rate and terms reduce the remaining borrowing cost enough to outweigh fees and any extension of the loan.

Can refinancing hurt even with a lower rate?

A much longer new term can keep you paying for more months. Compare total remaining payments, not just rate or monthly payment.

What numbers should I ask for?

Get the current payout, proposed APR, term, payment, fees and total amount payable under the new agreement.

A simple way to use this guide

Write the relevant numbers on one page before you make a decision. Keep the vehicle price, loan terms, insurance quote and expected ownership costs separate. Then change one assumption at a time. This makes it easier to see which part of the deal is actually responsible for a higher or lower total cost.
