A programmable electronic calculator is provided having a manually operable annuity switch with begin- and end-position settings, enabling a user to specify the type of annuity calculation to be performed. When the switch is set to the begin position, the annuity calculation is performed with payments due at the beginning of each payment period; when the switch is set to the end position, the annuity calculation is performed with payments due at the end of each payment period. The annuity calculation is performed under control of a routine stored in a read-only-memory (ROM) of a data processing unit.
