How to Use This Car Loan Calculator
Start by selecting New Car or Used Car — this changes the preset rates, depreciation estimates, and typical maintenance costs. Use the quick presets to load typical prices for common vehicle categories, or enter your exact vehicle price.
Enter your down payment and trade-in value — both reduce the loan amount. Add your local sales tax rate (varies by state, typically 5-10%) to see the true financed amount. Then choose your loan term and interest rate. The term comparison chart shows how different loan lengths affect your monthly payment and total interest simultaneously.
The Ongoing Costs section is where most car buyers underestimate their true expense. Fill in insurance, maintenance, and fuel costs to see your real all-in monthly cost — not just the loan payment. The Depreciation section estimates what your car will be worth when the loan ends, helping you understand your true net cost of ownership.
The affordability meter compares your total monthly car cost against your income. Financial experts recommend keeping all car-related expenses under 15-20% of gross monthly income — including loan payment, insurance, fuel, and maintenance combined.
New vs. Used Car — Real Cost Examples
Example 1: New Honda CR-V at $38,000
With 10% down ($3,800), 7.2% APR, 60-month term, and 8% sales tax: your loan amount is approximately $33,100, monthly payment is $657/month, and total interest over 5 years is about $6,300. Adding $160/month insurance, $100/month maintenance, and $200/month fuel brings your all-in cost to $1,117/month. The car is estimated to be worth around $18,500 after 5 years — you've paid $67,000 total to drive a $18,500 car.
Example 2: 3-Year-Old Honda CR-V at $26,000
Same vehicle, 3 years old, with 10% down ($2,600), 8.5% APR, 48-month term: loan amount ~$21,200, monthly payment $525/month, total interest about $3,900. Higher maintenance budget ($180/month) but lower insurance ($140/month). All-in: $1,045/month. You save roughly $4,000 in total interest plus the initial depreciation cost — and finish paying sooner.
Car Buying Tips That Save You Money
Get pre-approved first
Visit your bank or credit union before the dealership. A pre-approval gives you a rate benchmark and negotiating power. Dealers can sometimes beat it — but only if you show them what you have.
Shop at end of month/quarter
Dealers have monthly and quarterly quotas. Shopping in the last few days of the month — especially end of a quarter (March, June, September, December) — gives you the most leverage for discounts.
Negotiate price, not payment
Dealers love to focus on monthly payment because it obscures the total cost. Always negotiate the out-the-door price first, then discuss financing separately.
Get a pre-purchase inspection
For any used car, spend $100-150 on an independent mechanic inspection before buying. It can reveal hidden issues — or give you negotiating leverage on the price.
Check market value first
Use Kelley Blue Book (kbb.com) or Edmunds to know the fair market value before negotiating. Never pay sticker price for used, and look for invoice price on new vehicles.
Consider total cost of EVs
EVs have higher purchase prices but much lower fuel and maintenance costs. Factor in federal tax credits (up to $7,500 for qualifying new EVs) and your local electricity rates when comparing.
