About this calculator

Compare your current auto loan against a refinance offer to see the exact month you break even after fees, and how much total interest you'll save.

Frequently Asked Questions

How is break-even calculated?

We divide the refinance fees by your monthly payment savings to find how many months it takes for the savings to offset the cost of refinancing.

Should I refinance if the break-even is longer than I plan to keep the car?

Generally no — if you'll sell or pay off the car before the break-even month, refinancing may not be worth the fees.

Does this account for extending the loan term?

Yes, a longer new term can lower payments but increase total interest paid — check the total interest savings figure, which can be negative even if monthly payments drop.
