Ah, expenses—the necessary evils that keep your business running but also make your wallet feel lighter than a helium balloon. You’ve probably wondered, “Is an expense a debit or a credit?” If accounting jargon makes you feel like you’re decoding an ancient language, you’re in the right place.
We’re here to demystify debits and credits without putting you to sleep. Think of this as accounting explained over a cup of coffee—or maybe something stronger if that’s your style. We’ll sprinkle in some wit and real-life examples to keep things interesting. So, buckle up! By the end of this read, you’ll know exactly why expenses are debits and not credits. Trust us; it’s not rocket science.

What Are Debits and Credits? (No, They’re Not Your Frenemies)
First things first: let’s tackle the age-old concept of debits and credits. They’re the bread and butter of accounting, the yin and yang of your financial universe. But what do they actually mean?
In the world of double-entry accounting, every financial transaction affects at least two accounts: one debit and one credit. This system ensures that the books are always balanced, much like how a perfectly seasoned dish balances flavors. Here’s the lowdown:
- Debits increase expenses and assets, and decrease liabilities, equity, or revenue.
- Credits increase revenue, equity, or liabilities, and decrease expenses or assets.
Think of debits as money flowing into your business’s resources—like cash or equipment—and credits as money flowing out or obligations owed. When you buy a new laptop for your startup, the asset (Equipment) increases with a debit, and Cash decreases with a credit. Voilà! The transaction balances.
Double-Entry Accounting: The Dance of Debits and Credits
Welcome to double-entry accounting, the bookkeeping equivalent of a well-choreographed tango. For every financial move, there’s a mirrored counter-move. It’s all about balance—no awkward stumbles allowed.
Here’s how it works:
- Every transaction affects two (or more) accounts.
- Total debits always equal total credits for each transaction.
Why go through this hassle? Because double-entry accounting helps catch errors and provides a complete picture of your financial health. It’s like having a built-in spell-checker for your finances. Mistakes become glaringly obvious when things don’t add up.
Consider this example: You pay $500 for office rent.
- Debit: Rent Expense increases by $500.
- Credit: Cash decreases by $500.
Both sides balance, and your books stay in tip-top shape. It’s the financial equivalent of eating your veggies—might seem tedious, but your accountant (and future self) will thank you.
Why Are Expenses Debited? The Nitty-Gritty Explained
So, why exactly are expenses recorded as debits? Great question! Expenses decrease your owner’s equity or retained earnings. Since equity accounts have a natural credit balance, recording an expense (which reduces equity) requires a debit entry.

Here’s the breakdown:
- Expenses Increase with Debits: When you incur an expense, you’re essentially using up assets or incurring liabilities, which decreases equity. To reflect this, you debit the expense account.
- Credits Reduce Assets or Increase Liabilities: The corresponding credit entry either reduces an asset (like cash) or increases a liability (like accounts payable).
Think of it this way: Expenses are like that friend who always borrows money and never pays you back—they decrease your net worth. To account for this “loss,” you debit the expense account.
Examples: Seeing Debits and Credits in Action
Let’s bring this to life with some real-world scenarios. After all, what’s theory without a bit of practice?
Example 1: Paying for Office Supplies with Cash
You spend $200 on office supplies. Here’s how you’d record it:
- Debit: Office Supplies Expense increases by $200.
- Credit: Cash decreases by $200.
Your expense account goes up, and your cash asset goes down. Balance achieved. High-five!
Example 2: Incurred Utilities Expense on Credit
Your electricity bill arrives for $150, but you haven’t paid it yet. Here’s the journal entry:
- Debit: Utilities Expense increases by $150.
- Credit: Accounts Payable increases by $150.
You record the expense now and the liability to pay later. Because who doesn’t love postponing bills?
Example 3: Paying Off an Accounts Payable
Time to settle that $150 electricity bill. Here’s how you’d record the payment:
- Debit: Accounts Payable decreases by $150.
- Credit: Cash decreases by $150.
No expense account involved here since you already recorded the expense when you received the bill. You’re just balancing out your liabilities and assets.
Breaking Down the Expense Account
The expense account is like the weight you gain during the holidays—it’s easier to add to than to subtract from. It records all the costs incurred in generating revenue, from office rent to that fancy new espresso machine (because caffeine fuels productivity, right?).

Expense accounts can be divided into sub-accounts for more detailed tracking:
- Wages Expense
- Utilities Expense
- Rent Expense
- Advertising Expense
- Depreciation Expense
These accounts help you see where your money is going so you can make informed decisions. Maybe it’s time to cut back on the artisan coffee runs?
