Calverton may have been named after Calvert County, Maryland. Gilbert Bastable's family moved to the Warrenton Junction area from Maryland between 1850 and 1860, and Bastable lived in Calvert County prior to returning to Virginia after the Civil War.

Calverton is located in southeastern Fauquier County, between Catlett to the northeast and Midland to the southwest, all along Virginia Route 28. Warrenton, the county seat, is 10 miles (16 km) to the northwest via Casanova Road and Meetze Road.

According to the U.S. Census Bureau, the Calverton CDP has a total area of 4.61 square miles (11.95 km), of which 4.59 square miles (11.88 km) is land and 0.027 square miles (0.07 km), or 0.59%, is water. Owl Run flows through the center of Calverton; it is a tributary of Cedar Run, part of the Occoquan River watershed flowing to the Potomac River.

The Fauquier County government's vision for Calverton is, "Calverton will be a small rural village centered within an agricultural community. It will be a livable community with a balance of residential and non-residential development surrounded by open space and preserved wildlife." The county established less ambitious goals for Calverton's growth due to the challenges it faced in trying to deal with failed and failing septic drain fields in Calverton by providing public sewers.
