The impact of larger down payments

Why shorter terms save money

3. Mobile-Friendly Design

Works perfectly on:

📱 Smartphones

💻 Tablets

🖥️ Desktop computers

Pro Tips for Car Buyers

1. Improve Your Loan Terms

Boost Your Credit Score: A 700+ score can lower rates by 2-3%

Consider Credit Unions: Often offer better rates than banks

Make Biweekly Payments: 26 half-payments = 13 full payments/year (saves interest)

2. Avoid Common Mistakes

❌ Focusing only on monthly payment (longer terms cost more overall)

❌ Rolling negative equity into a new loan

❌ Skipping gap insurance for loans >80% of car value

3. Negotiation Strategies

Secure financing first: Walk in with pre-approval

Discuss price before mentioning trade-in

Ask about "dealer reserve" fees (often 1-2% of loan amount)

Technical Details

Formulas Used

Monthly Payment Calculation:

M = P [ i(1 + i)^n ] / [ (1 + i)^n – 1]

Where:

M = Monthly payment

P = Principal amount

i = Monthly interest rate

n = Number of payments

Amortization Schedule:

Each payment's interest portion = Current balance × monthly rate

State-Specific Logic

The calculator automatically adjusts for states that:

Tax trade-in differences (CA, HI, etc.)

Offer EV tax credits

Auto Loan Tips

• Shop around for the best rates: Compare offers from multiple lenders before committing.
• Consider a shorter loan term: While monthly payments will be higher, you'll pay less interest overall.
• Make a larger down payment: This reduces the amount you need to borrow and can lower your interest rate.
• Check your credit score: A higher score can qualify you for better interest rates.
• Factor in all costs: Remember to include taxes, fees, and insurance in your budget.
