Carleton Releases CarCalcs API
Carleton has released a new tax, title, and dealer fee API integrated with Automotive Titling Corp.’s title and registration product.

SOUTH BEND, Ind. — Carleton has released CarCalcs, a comprehensive and integrated sales tax, registration, and dealer fee API to complement its CarletonCalcs solution. Directors said the new API integrates Automotive Titling Corp.’s title and registration product into a single data channel delivery service.
“For over two decades, ATC has processed thousands of transactions through DMVs all over the country. This has facilitated our ability to build, catalog and uniquely authenticate the most accurate sales tax and registration fee database in the industry,” said Ken Alley, president of ATC. “Our authentication process is a full-time focus of our expert team.”
CarCalcs was designed to be an easy and flexible integration for any platform provider in order to connect and populate dealer admin settings. The application features seamless dealer onboarding and real-time access to registration and dealer fee values, and the data returned from the API is delivered in a format easily consumed by the CarletonCalcs payment computation module for the precise calculation of retail sales or leases, all according to the announcement.
“We saw a critical need for additional components to calculate accurate payment computations. This was the impetus for developing CarCalcs. Through our partnership with ATC, we have expanded our calculation offerings to include sales tax and registration fees,” said Carleton’s president and COO, Matt Ruszkowski. “We knew we needed a partner with the same level of expertise as our proven calculation services. Partnering with ATC was a logical decision.”
