How we find the lowest new auto loan rate
RateAPI scrapes new auto loan rates directly from credit union websites every day — thousands of them, most with no API and no advertising budget. We normalize every rate, rank by true cost (APR, not teaser rate), and surface the lowest. The cheapest rate is rarely from a big advertiser; it's usually a smaller credit union you'd never find on a comparison site.
Rates vary by state, credit score, and term. To see the lowest new auto loan rate near you, browse auto loan rates by state, or query the data directly through the API.
