Abstract
A calculator apparatus is provided for computing minimum principal amounts for deposit into demand (passbook) accounts and into term (certificate-of-deposit) accounts paying interest at differing rates. The computed minimum principal amounts not only satisfy the minimum deposit requirements of the term accounts but, when deposited, provide both maximum interest earnings and payments from principal, without interest penalty ordinarily associated with early withdrawals. The apparatus comprises a keyboard, a read-write memory, a logic unit, a printer, and a display unit. The logic unit includes an arithmetic unit having a plurality of data storage registers and a read-only-memory with a stored program. The apparatus computes the minimum principal amounts in accordance with the stored program and in response to entered data.
