Summary of Week 3
The three concepts that form the basis of double-entry accounting are the business entity concept, the accounting equation and the duality concept. The business entity concept means that a business is separate from the owner(s) of the business. The accounting equation for any business states that Assets = Capital + Liabilities. The duality concept means that every transaction has two effects.
The basic principle of double-entry accounting is for every transaction recorded there should be a debit entry and a credit entry in the relevant T-accounts according to the following double-entry rules:
| Account name | Effect of transaction | Debit | Credit |
| Asset | Increase | Debit | |
| Decrease | Credit | ||
| Liability | Increase | Credit | |
| Decrease | Debit | ||
| Capital | Increase | Credit | |
| Decrease | Debit |
