'''Programmable calculators''' are [[calculator]]s that can automatically carry out a sequence of operations under control of a stored [[computer programming|program]]. Most are [[Turing complete]], and, as such, are theoretically general-purpose computers. However, their user interfaces and programming environments are specifically tailored to make performing small-scale numerical computations convenient, rather than general-purpose use.

The first programmable calculators such as the [[IBM CPC]] used [[punched cards]] or other media for program storage. Hand-held electronic calculators store programs on magnetic strips, removable read-only memory cartridges, flash memory, or in battery-backed read/write memory.
