Whether a debit increases or decreases an account's net balance depends on what kind of account it is.

To determine whether to debit or credit a specific account, we use either the accounting equation approach (based on five accounting rules), or the classical approach (based on three rules). This sort of abstraction is already apparent in Richard Dafforne's 17th-century text The Merchant's Mirror, where he states 'Cash representeth (to me) a man to whom I … have put my money into his keeping the which by reason is obliged to render it back.' beyond their original personal connotation and apply them to inanimate objects and abstract conceptions.' '.it became the practice to extend the meanings of the terms. 'if we today would abolish the use of the words debit and credit in the ledger and substitute the ancient terms of 'shall give' and 'shall have' or 'shall receive', the personification of accounts in the proper way would not be difficult and, with it, bookkeeping would become more intelligent to the proprietor, the layman and the student.' Īs Jackson has noted, 'debtor' need not be a person, but can be an abstract party:

Geijsbeek the translator suggests in the preface: for debtor.) The words actually used by Pacioli for the left and right sides of the Ledger are 'in dare' and 'in havere' ( give and receive). as an abbreviation for the English word 'debtor.' (Sherman could not locate a first edition, but speculates that it too used Dr. Sherman goes on to say that the earliest text he found that actually uses 'Dr.' as an abbreviation in this context was an English text, the third edition (1633) of Ralph Handson's book Analysis or Resolution of Merchant Accompts and that Handson uses Dr. However, Sherman casts doubt on this idea because Pacioli uses Per (Italian for 'by') for the debtor and A (Italian for 'to') for the creditor in the Journal entries. Under this theory, the abbreviations Dr (for debit) and Cr (for credit) derive directly from the original Latin. When his work was translated, the Latin words debere and credere became the English debit and credit. At the time negative numbers were not in use. Assets were owed to the owner and the owners' equity was entrusted to the company. It is sometimes said that, in its original Latin, Pacioli's Summa used the Latin words debere (to owe) and credere (to entrust) to describe the two sides of a closed accounting transaction. Indian merchants had developed a double-entry bookkeeping system, called bahi-khata, predating Pacioli's work by at least many centuries, and which was likely a direct precursor of the European adaptation.

This system is still the fundamental system in use by modern bookkeepers. Pacioli devoted one section of his book to documenting and describing the double-entry bookkeeping system in use during the Renaissance by Venetian merchants, traders and bankers. The first known recorded use of the terms is Venetian Luca Pacioli's 1494 work, Summa de Arithmetica, Geometria, Proportioni et Proportionalita ( A Summary of Arithmetic, Geometry, Proportions and Proportionality). Instead the correspondence depends on the normal balance convention of the particular account. Debits and credits do not, however, correspond in a fixed way to positive and negative numbers. Alternatively, debits and credits can be listed in one column, indicating debits with the suffix 'Dr' or writing them plain, and indicating credits with the suffix 'Cr' or a minus sign. This practice simplified the manual calculation of net balances before the introduction of computers each column was added separately, and then the smaller total was subtracted from the larger. Similarly, the landlord would enter a credit in the rent income account associated with the tenant and a debit for the bank account where the cheque is deposited.ĭebits and credits are traditionally distinguished by writing the transfer amounts in separate columns of an account book. For example, a tenant who writes a rent cheque to a landlord would enter a credit for the bank account on which the cheque is drawn, and a debit in a rent expense account. Each transaction transfers value from credited accounts to debited accounts. A debit entry in an account represents a transfer of value to that account, and a credit entry represents a transfer from the account. Debits and credits in double-entry bookkeeping are entries made in account ledgers to record changes in value resulting from business transactions.
