What are expense accounts?

Definition of expense accounts

Expense accounts are categories within the business's books that show how much it has spent on its day-to-day running costs.

A debit to an expense account means the business has spent more money on a cost (i.e. increases the expense), and a credit to a liability account means the business has had a cost refunded or reduced (i.e. reduces the expense).

Expense accounts in double-entry bookkeeping

In double-entry bookkeeping, there are five types of nominal accounts:

• Income accounts: what the business has earned
• Expense accounts: the business's day-to-day running costs
• Asset accounts: what the business owns
• Liability accounts: what the business owes
• Capital accounts: what is owed to or by the business owner

How debits and credits work for different accounts

To increase the amount in your business accounts, you need to debit some accounts and credit others. What you do depends on the kind of account you’re dealing with:

• for an income account, you credit to increase it and debit to decrease it
• for an expense account, you debit to increase it, and credit to decrease it
• for an asset account, you debit to increase it and credit to decrease it
• for a liability account you credit to increase it and debit to decrease it
• for a capital account, you credit to increase it and debit to decrease it

Where to find your expense accounts

Expense accounts appear on the business's profit and loss account.
