What this calculator does
Most finance tools bury the answer under ads and jargon. The car loan calculator shows the number first, the breakdown next, and the assumptions in plain language.
Car loans finance vehicle purchases. Terms typically range from 36 to 84 months.
How to use the Car Loan Calculator
- Start by entering **Vehicle Price** — this anchors every downstream number in the car loan calculator.
- Fill in **Down Payment**, **Trade-in**, **APR** to reflect your specific situation.
- Set **Term**; the result and chart recalculate the moment you finish typing.
- Review the breakdown card for the components that make up the headline number.
- Use Copy, Share, or Print to save the exact scenario — or star it to keep it in your favorites.
The formula
M = P·r(1+r)^n / ((1+r)^n−1) where P = price − down − trade-in.
Worked example
$30,000 car with $5,000 down at 7% for 5 years = ~$495/month.
Common mistakes
- Focusing on monthly payment vs total cost
- Extending term to 72–84 months
- Skipping GAP insurance for long loans
When to use it
Use before visiting a dealer or accepting financing offers.
