Key takeaways

• Recognize that debits increase assets and expenses, while credits increase liabilities, equity, and revenue — use the memory aids "EA" for debit accounts and "LER" for credit accounts to quickly identify the correct entry for any transaction.
• Apply double-entry bookkeeping to every transaction by ensuring each debit has a matching credit of equal value, which keeps your books balanced and your financial records accurate.
• Maintain balanced books to support key business activities, including securing loans, staying tax compliant, and attracting investors who rely on accurate financial statements to assess your business.
• Use a T-account to calculate account balances by totaling all debits on the left and all credits on the right, then subtracting the smaller total from the larger to find the difference — and review your entries immediately if the totals don't match.

Defining debits vs credits

Debits are entries on the left side of your general ledger that increase asset and expense accounts. Credits are entries on the right side that increase liability, equity, and revenue accounts.

In double-entry bookkeeping, every transaction requires both a debit and a credit entry. Your general ledger tracks all these transactions to maintain accurate financial records.

The importance of debits and credits

Balanced debits and credits keep your financial records accurate and your books in order. When debits equal credits, you maintain reliable data that supports critical business activities.

Accurate records help you:

• secure financing: Lenders review balanced books when making credit decisions
• stay tax compliant: The IRS requires accurate financial records, with some items like employment taxes requiring four years of documentation
• attract investors: Investors analyze balanced statements to assess business health and make funding decisions

Understanding double-entry bookkeeping

Double-entry bookkeeping is an accounting method where every transaction affects at least two accounts. One account receives a debit, and another receives a credit.

This system keeps your books balanced at all times. You get a clear view of your financial health and can track exactly where your money comes from and where it goes.

Rules you need to know

Five fundamental rules govern how debits and credits work in double-entry accounting. Master these rules to maintain accurate financial records:

• Debits must equal credits: Every transaction must balance for your books to stay accurate
• Debits go on the left, credits go on the right: This placement never changes in any accounting system
• Debits increase assets and expenses: Credits decrease these same accounts
• Credits increase liabilities, equity, and revenue: Debits decrease these same accounts
• Every debit requires a corresponding credit: The two entries must equal each other in value

Five types of accounts and how debits and credits affect them

Five main account types organize all your business transactions in the general ledger. Each account tracks different aspects of your finances and can include sub-accounts for more detailed tracking.

The five essential accounts are:

• Asset account
• Expense account
• Equity account
• Liability account
• Revenue account

1. Asset account

Asset accounts track everything your business owns that has value. A debit increases an asset account, and a credit decreases it.

Assets include physical items like equipment and intangible items like patents. Current assets are items you expect to convert to cash within one year.

Common asset sub-accounts include:

• petty cash
• inventory
• accounts receivable
• bank accounts

2. Expense account

Expense accounts track the costs you incur to run your business. A debit increases an expense account, and a credit decreases it.

Common expenses include wages, office supplies, advertising, and rent. Organize your expense account with sub-accounts like:

• cost of goods sold (COGS)
• insurance expenses
• payroll expenses
• rent
• office expenses

3. Equity account

Equity accounts represent your business's net worth, calculated as total assets minus liabilities. A debit decreases an equity account, and a credit increases it.

Equity is critical for financial analyzes like the debt-to-equity ratio, which shows how much debt finances your assets compared to shareholder value.

Common equity sub-accounts include:

• owner's equity
• retained earnings

4. Liability account

Liability accounts track amounts your business owes but hasn't yet paid. A debit decreases a liability account, and a credit increases it.

Common liabilities include loans, credit card balances, and taxes owed. Organize your liability account with sub-accounts like:

• accounts payable
• collected sales tax
• payroll tax

5. Revenue account

Revenue accounts track all the income your business earns. A debit decreases a revenue account, and a credit increases it.

Revenue includes sales income and investment earnings. Use sub-accounts to track where your income comes from:

• investments
• product sales: online sales
• product sales: store sales

Debits and credits in action: Common examples

Seeing debits and credits applied to real transactions helps you understand how the rules work in practice. Here are three common small business scenarios.

Example 1: Purchasing inventory with cash

You buy $500 of inventory and pay cash.

• Debit: Inventory account (asset) increases by $500
• Credit: Cash account (asset) decreases by $500

Both accounts are assets, but inventory goes up while cash goes down. The $500 debit equals the $500 credit, keeping your books balanced.

Example 2: Recording a customer sale on credit

A customer buys $1,000 of products and agrees to pay later.

• Debit: Accounts receivable (asset) increases by $1,000
• Credit: Sales revenue (revenue) increases by $1,000

Your accounts receivable goes up because the customer owes you money. Your revenue also increases because you made a sale. The entries balance at $1,000 each.

Example 3: Paying monthly rent

You pay $2,000 for this month's rent.

• Debit: Rent expense (expense) increases by $2,000
• Credit: Cash account (asset) decreases by $2,000

Your rent expense increases because you incurred a cost. Your cash decreases because you paid money out. Both entries equal $2,000.

How to remember debits and credits

A simple memory aid helps you remember which accounts increase with debits versus credits.

Use this grouping to remember which accounts increase with each entry type:

• Debits increase: expenses and assets (think "EA")
• Credits increase: liabilities, equity, and revenue (think "LER")

When you're unsure which entry to make, ask yourself: "Does this transaction increase an EA account or a LER account?" The answer tells you whether to debit or credit.

Calculating the balance

To calculate account balances, add up all debits and credits for each account, then find the difference. A T-account is a visual tool that makes this process easier.

A T-account has three main components:

• Top: Account name
• Left side: All debit entries
• Right side: All credit entries

Follow these steps to calculate your balance:

1. Add up all debit entries for the account
2. Add up all credit entries for the account
3. Subtract the smaller total from the larger total
4. Record the difference as your account balance

If totals don't match, review your entries to find and correct errors before proceeding.

FAQs on debits and credits

Here are answers to common questions about debits and credits for small businesses.

Is a debit money in or out?

It depends on the account type. For asset accounts like your bank account, a debit means money coming in. For liability accounts like a loan, a debit means money going out to reduce what you owe.

What are the seven rules of debit and credit?

The rules are based on the five main account types:

• Debits increase asset and expense accounts
• Credits decrease asset and expense accounts
• Credits increase liability, equity, and revenue accounts
• Debits decrease liability, equity, and revenue accounts
• Debits always appear on the left
• Credits always appear on the right
• Total debits must equal total credits

What is the easiest way to remember debits and credits?

Group accounts by what increases them. Debits increase expenses and assets (EA). Credits increase liabilities, equity, and revenue (LER). When recording a transaction, identify the account type first, then apply the matching rule.

How do you know if an account should be debited or credited?

Follow these steps to determine the correct entry:

1. Identify which accounts the transaction affects
2. Determine each account's type (asset, liability, equity, expense, or revenue)
3. Decide whether the transaction increases or decreases each account
4. Apply the correct rule: debits increase assets and expenses; credits increase liabilities, equity, and revenue

What happens if debits don't equal credits?

Unbalanced debits and credits signal an error in your records. Your financial reports won't be accurate until you find and correct the mistake. Review recent entries, check for transposed numbers, and verify each transaction affects the correct accounts.
