The Calculator is a fictional supervillain published by DC Comics. He first appeared in Detective Comics #463 (September 1976), and he was created by Bob Rozakis and Mike Grell.

As is commonplace in comics, the character was based on a topical event or trend; in this case, Noah Kuttler took his powers and costume design from the recently-popular pocket calculator. His costume had a large numerical keypad on the front and a flashlight-like device on the headpiece. When he typed upon the keypad, he could make "hard light" constructs appear from the headpiece, fashioning tools and weapons in the style of Green Lantern's power ring.

He was featured in a series of one-shot adventures in Detective Comics, stealing objects "when they are their most valuable" and fighting many Justice League members. As he was defeated by hero after hero, he presses a special button on his keypad that would (as it was revealed to the reader in a thought balloon) "turn defeat into victory". After months of appearances, the Calculator's scheme is revealed. The button somehow analyzes the powers or tactics of the hero defeating him, and effectively inoculates him from ever being defeated by that hero ever again. This immunity manifests itself as a force field, rendering a hero unable to touch or otherwise affect The Calculator. This of course meant he could only be defeated by a new hero; fortunately the heroes had many allies to drawn upon. The Calculator could also be defeated when his own weaponry was turned against him.

The Calculator made intermittent appearances in DC titles over the years, such as Blue Beetle. In the 2004 miniseries Identity Crisis, he was revamped as a non-costumed villainous analogue to Oracle; a source of information for supervillains planning heists, offering suggestions of weaponry, assisting with logistics, etc. — but charging $1,000 per question, unlike Oracle, who works pro bono. He became a major player in the Infinite Crisis cross-over Villains United as a core member of Lex Luthor's The Society. His allies included such villains as Doctor Psycho, Doctor Light and Deathstroke.

The Calculator has not been a contender in any CBUB matches.
