The number of the sections corresponds to the number of items. Each section has a first memory area for storing a budget data and a second memory area for storing a cumulative expenditures. A key board provided on the casing has number keys for effecting the input of a numerical data, a plurality of item keys for effecting an access to a corresponding section in the memory upon depression of one item key, a mode key for changing the mode between a first mode for entering the budget data in the first memory area, and the second mode for entering the cumulative expenditure in the second memory area. A display is provided for displaying a numerical data inputted by the number keys, and a controller is provided to operate in response to a depression of one of the item keys such that, while the first mode is established, a numerical data as inputted by the number keys is entered and stored in the first memory area as the budget data, and that, while the second mode is established, a numerical data as inputted by the number keys is added to the cumulative expenditure previously stored in the second memory area in the second memory area.
