Double entry bookkeeping is a method of accounting that has been the backbone of financial record-keeping for centuries. This system ensures that every transaction affects at least two accounts, maintaining a balance between debits and credits.
Historical Context
The double entry bookkeeping system dates back to the 15th century and is attributed to the work of Luca Pacioli, an Italian mathematician and Franciscan friar. Pacioli’s seminal work, Summa de Arithmetica, Geometria, Proportioni et Proportionalita, published in 1494, included a section on bookkeeping that outlined the double entry system. This publication is often considered the birth of modern accounting.

Detailed Explanation
Basic Principle
In double entry bookkeeping, every financial transaction is recorded twice:
- Debit Entry: Increases assets or expenses, and decreases liabilities or equity.
- Credit Entry: Increases liabilities or equity, and decreases assets or expenses.
For example, if a business takes a loan of $1,000, the entries would be:
- Debit: Bank Account (Asset) $1,000
- Credit: Loan Account (Liability) $1,000
This ensures that the accounting equation (Assets = Liabilities + Equity) always remains balanced.
Mathematical Formulas and Models
The foundational formula for double entry bookkeeping is the accounting equation:
Example Journal Entry
When a company purchases office supplies for $500 on credit:
- Debit: Office Supplies (Asset) $500
- Credit: Accounts Payable (Liability) $500
