Biweekly-payment math, extra-payment strategy, when to refinance — the methods that actually cut interest.

When to refinance, credit-score thresholds, shopping 3-5 lenders, cash-out vs rate-and-term — what dealers won't tell you.

📌 5 Tips to Save on Your Car Loan

✓ Even $50/month extra on a $32K loan at 7.5% saves ~$1,200 in interest and cuts ~7 months off the term.
✓ Biweekly payments (half your monthly payment every 2 weeks) make 13 full payments per year instead of 12 — no extra effort, just smarter timing.
✓ Apply tax refunds & bonuses as one-time extra payments to slash principal at year 1 or 2 (when interest is highest).
✓ Refinance at month 6-12 if your credit score has improved — even 1% APR lower saves hundreds on a 60-month loan.
✓ Trade-in + down payment reduce the financed amount more than they reduce the monthly payment — every $1K less financed saves $150-$300 in total interest.
