How Car Loan Calculations Work
A car loan calculator helps you understand the true cost of financing a vehicle before you sign anything at the dealership. The monthly payment is calculated using the standard amortization formula based on loan amount, interest rate, and term.
Key Factors That Affect Your Payment
- Loan Amount: Car price minus your down payment and trade-in value.
- APR (Annual Percentage Rate): Your credit score is the biggest determinant. A 760+ score can get rates below 5%, while sub-600 scores may face 15%+ rates.
- Loan Term: Longer terms (72-84 months) lower monthly payments but dramatically increase total interest paid.
Dealer vs. Bank Financing
Always get pre-approved from your bank or credit union before visiting a dealer. Dealers often mark up the interest rate and earn a commission. Having a competing offer gives you negotiation power on both the car price and the financing rate.
