Debit vs. Credit (如何理解会计中的借和贷)

In accounting terms, when they are used as verbs (vt. 即物动词):

  • Debit (借入) = take in assets (from)
  • Credit (贷出) = give out assets (to)

When they are used as nouns:

  • Debit(s) (借入的资产) = assets taken in
  • Credit(s) (贷出的资产) = assets given out

Basically, for a given subject, debit means inflow (into it) while credit means outflow (from it). (借入贷出)

The subject can be any economic entity or account. It can be a company, a company’s asset account, a bank, an organization, a government, or an independent person who simply wants to keep books of his living expenses, etc..

Verbal Examples

The subject below is the bank.

    • The bank debits my account $500.
    • My account is debited $500 by the bank.

The bank takes in $500 from my account.

As a reverse example, the subject below is my account.

    • My account credits the bank $500.
    • The bank is credited $500 by my account.

My account gives out $500 to the bank.

Accounting Examples

Company A issues debt to company B, or company A borrows cash from company B.

In the books of A:

  • Debit: Cash
  • Credit: Loan Payable

In the books of B:

  • Debit: Loan Receivable
  • Credit: Cash

Debit card vs. Credit card

A debit card is called debit because the card issuer (subject) must debit to credit. The issuer / bank must take in to give out.

A credit card is called credit because the card issuer (subject) can credit before debiting. The issuer / bank can give out before taking in.

会计恒等式

资产 + 成本、费用=负债+所有者权益+利润

借贷记账法的账户结构

借方表示资产流入(借入),贷方表示资产流出(贷出)。

借贷账户的基本结构是:左方为借方,右方为贷方,但哪一方登记增加,哪一方登记减少,则要根据账户反映的经济内容决定。可以分为四类:

  1. 资产类账户:增加额记借方,减少额记贷方,期末如有余额在借方。这个很好理解。
  2. 权益(负债及所有者权益)类账户:增加额记贷方,减少额记借方,期末如有余额在贷方。此账户的贷方,表示资产流出到了资产类账户(记资产类的借方),所以权益增加;此账户的借方,表示资产从资产类账户流入该账户(记资产类的贷方),所以权益减少。
  3. 成本费用类账户:增加额记借方,减少或转销额记贷方,费用结转后一般无余额,如有余额在借方。此账户的借方,表示资产从资产类账户流入该账户(记资产类的贷方),即成本费用增加;此账户的贷方,表示资产流出到了资产类账户(记资产类的借方),即成本费用减少。
  4. 收入、利润类账户:增加额记贷方,减少或转销额记借方,收入、利润结转后期末应无余额。同上理解。

借贷记账法的记账规则

有借必有贷,借贷必相等。

借贷记账法的试算平衡

每一笔经济业务的会计分录都是借贷相等,因而当全部经济都记入账户后,所有账户的本期借方发生额合计与本期贷方发生额合计,必定相等;所有账户的期末借方余额合计与期末贷方合计也必定相等。
