Worked example
Recovering $600 in refinance costs
Upfront costs$600
Monthly saving$60
Simple break-even10 months
The example assumes the payment reduction remains constant and excludes future refinancing or early sale.
Start with the payoff balance
Use today’s lender payoff amount and remaining months—not the original loan amount and term.
Separate payment relief from savings
A longer new term can lower the required payment but increase total interest.
- Compare total remaining payments.
- Include lender, title, and payoff fees.
- Treat cash-out proceeds as borrowed money.
Use your decision horizon
If you may sell the car before the modeled break-even month, the refinance may not recover its costs.
Frequently asked questions
What if break-even is unavailable?
The proposed payment is not lower enough to recover the entered costs using simple monthly savings.
Can total savings disagree with break-even?
Yes. Term changes can create payment savings without lifetime savings.
