In all the world, Kalkul (Калкуль 
, Калкул , Kalkul 
) is a very rare dominantly feminine, but infrequently male given name. The first name Kalkul is habitual in Central Asia, particularly Kazakhstan, where it is a rare predominantly girly, but scarcely boy's name. Very seldom, Kalkul is the last name as well as the forename.
