Debits and Credits

Debits and Credits
I thought about calling this lesson "The Revenge of The Nerds". The nerds, in this case, being us accountant types. Students and others studying accounting and bookkeeping probably think that debits and credits are our (accountants) way of paying them back for poking fun at our profession. Actually, there's really nothing difficult about debits and credits. It's just our method used to record business transactions.
In bookkeeping, every financial transaction is recorded using a system called double-entry accounting. This means every transaction affects at least two accounts. If something goes out, something else must come in. Think of double-entry bookkeeping as the central nervous system of modern business. It is a system that has been used for centuries because it has a built-in mechanism for accuracy: every single financial event has a cause and an effect.

In double-entry bookkeeping, every transaction affects at least two accounts. If you take money out of one place, it must go into another. This ensures that your financial records always stay perfectly balanced. In other words, the double entry bookkeeping system keeps the Accounting Equation
balanced !

What do we use to record the changes, the increases and decreases to account balances ?
To keep track of these changes, we use Debits and Credits.

Instead of thinking of these terms as "plus" or "minus," or "good" or "bad," it is best to learn their simplest definition in accounting:
  • Debit simply means the left side of an account ledger.
  • Credit simply means the right side of an account ledger.

Every single transaction you record using the double entry bookkeeping system will have a debit entry on the left side of one account, and a corresponding credit entry on the right side of another account.

The Golden Rule of Bookkeeping: Total Debits must always equal Total Credits for every transaction.

The Accounting Equation: Whether a debit or a credit increases or decreases an account depends entirely on the type of account you are working with. Everything ties back to the Expanded Accounting Equation: Assets equal Liabilities plus Owner Capital minus Owner Drawings plus Revenues minus Expenses.

Here is how the rules break down for the main account types:
1. Assets (What the business owns - Cash, Inventory, Equipment) Increase with a Debit (Left side) and Decrease with a Credit (Right side)
2. Liabilities (What the business owes to others - Accounts Payable, Loans) Decreases with a Debit (Left side)and Increases with a Credit (Right side)
3. Equity (The owner's investment and value in the business) Decreases with a Debit (Left side)and Increases with a Credit (Right side)  

The Equity Components Rules
(a) Owner's Capital (What the owners invest in the business) Decreases with a Debit (Left side)and Increases with a Credit (Right side)
(b) Revenue (What the business earns- Sales of products and services) Decreases with a Debit (Left side)and Increases with a Credit (Right side)
(c) Draws or Dividends (Money taken out of the business by the owners) Increases with a Debit (Left side) and Decreases with a Credit (Right side)
(d) Expenses (Costs of running the business - Rent, Utilities, Advertising) Increases with a Debit (Left side) and Decreases with a Credit (Right side)

Let's end with a complete definition for debits and credits.
Debit: An entry (amount) entered on the left side (column) of a journal or general ledger account that increases an asset, draw or an expense or an entry that decreases a liability, owner’s equity (capital) or revenue.
Credit:An entry (amount) entered on the right side (column) of a journal or general ledger account that increases a liability, owner’s equity (capital) or revenue , or an entry that decreases an asset, draw, or an expense.
