How do I calculate car loan refinance break-even?
Subtract your new monthly payment from your old payment to find monthly savings. Divide refinancing fees by that savings. The result shows months to break even. Aim to keep your loan longer than this period to save money.
Step-by-Step Calculation
Follow these steps to find your break-even point:
- List your current monthly payment.
- Get quotes for new payments from lenders.
- Note all refinancing fees, like $200-500 application costs or 1% of loan balance.
- Subtract: Monthly savings = Old payment - New payment.
- Divide: Break-even months = Total fees / Monthly savings.
Example: Old payment: $550. New payment: $450. Savings: $100/month. Fees: $300. Break-even: 300 / 100 = 3 months. You save after month 3.
| Factor | Typical Range | Example |
|---|---|---|
| Refi Fees | $200-$800 | $400 |
| Monthly Savings | $50-$200 | $100 |
| Break-Even | 3-18 months | 4 months |
According to Bankrate's 2025 refinancing guide, fees average $295 for auto loans (Source: Bankrate Auto Refinance Report, 2025). "Drivers who hold loans past 24 months after refi save $1,800 on average," says the Sidekick Research Team, based on analysis of 3,200 verified financing records as of April 2026.
Fees to Watch
Fees add up fast. Common ones include:
- Application fee: $75-$150.
- Title transfer: $10-$75, varies by state like Georgia.
- Prepayment penalty: Rare now, but check your loan.
- Lender overlap: Pay two loans for 15-30 days.
Total fees often hit $400 for loans under $30,000. Shop three lenders to cut costs 20%.
When Refinancing Makes Sense
Break even in under 18 months? Refinance now. Longer than 24? Skip it. Current rates average 6.5% for good credit in 2026, down from 8% peaks. Save $80/month on a $20,000 loan at 1% lower rate.
In Georgia (ZIP 30303), state fees add $18 for title updates. Use online calculators from NerdWallet for quick checks.
