How Car Loan Payments are Calculated (Formula)
Loan Amount = Price × (1 + Tax%) — Down Payment
Monthly Payment = P × r × (1+r)n / ((1+r)n — 1)
Total Paid = Monthly Payment × Term (months)
Where P = Loan Amount, r = Monthly Interest Rate (APR ÷ 12 ÷ 100), n = Number of months

Frequently Asked Questions
What APR should I expect for a car loan?
2026 averages based on credit score (new car):
– Excellent (780+): 4-5% APR
– Good (700-779): 5-7% APR
– Fair (620-699): 7-12% APR
– Poor (below 620): 12-18%+ APR
Used car rates are typically 2-3% higher than new car rates.
What’s the best car loan term?
36-48 months (3-4 years): Lowest total interest, builds equity faster
60 months (5 years): Most common — balances payment and interest
72-84 months (6-7 years): Lower payment but MUCH higher total interest — often means you’ll be upside down (owe more than car’s value).
How does down payment affect my loan?
Larger down payment means:
– Lower loan amount → lower monthly payment
– Less interest → saves money over loan term
– Better loan terms → may qualify for lower APR
– Avoid being upside down → car value > loan balance from day 1
Recommended down payment: 20% of vehicle price ($5,600 on $28k car).
Should I include sales tax in the loan?
Many dealers allow you to finance sales tax (roll into loan). This lowers upfront cost but increases loan amount and total interest. Option 1: Pay tax upfront to save interest. Option 2: Finance tax for lower out-of-pocket today.
How to get the best car loan rate?
Shop around before visiting dealerships:
– Credit unions often have lowest rates
– Banks — check pre-approval before shopping
– Online lenders — LightStream, Capital One, Carvana
– Dealer financing — may have promotional rates (0-2% for new cars)
Get pre-approved — then negotiate price, not payment.
What’s the difference between APR and interest rate on a car loan?
Interest rate = cost of borrowing principal
APR = interest rate + fees (origination, processing).
For car loans, APR is usually very close to interest rate. Compare APR between lenders for true cost.
