1 Introduction to Accounting
What is accounting?
Accounting is the process of recording, analyzing, and summarizing financial transactions. Accounting uses the five types of accounts to record all the transactions.
In accounting, the five types of accounts are:
- assets: resources owned by a business; what the company owns
- liabilities: debts of the company; what the company owes
- equity: claim on the assets by the owners; calculated as equity = assets – liabilities; equity is the net worth of the company
- revenues: when a business receives assets from selling products and services
- expenses: when a business uses or consumes assets to create revenues
The goal of financial accounting, or financial reporting, is to issue financial statements.
There are four financial statements that each company prepares. The four financial statements are:
- income statement: revenues minus expenses equal net income or net loss
- balance sheet: lists all the assets, liabilities, and equity of a company
- cash flow statement: cash inflows and cash outflows
- statement of owners’ equity: shows the changes in equity on the balance sheet

2 Recording Business Transactions
Recording journal entries
Recording transactions in accounting uses a system called debits and credits. You need to learn the accounts and how to make journal entries into the accounts.
To record business transactions, use the debit and credit rules. All the transactions are recorded in a journal. These are called journal entries.
A journal shows all the transactions for the accounting period. These entries are posted to the ledger, which contains all the account balances.

4 Accounting for Merchandising Activities
A service company sells a service to its customers. A merchandising company sells products. Accounting for merchandising companies that sell products is more complex than for service companies.
This lesson introduces companies that buy and sell inventory and the concept of cost of goods sold.
Cost of goods sold (COGS) is the cost of selling the products to customers. For most companies, the cost of goods sold is the largest expense on the income statement. The cost of goods sold is also called:
- cost of goods
- cost of sales
- cost of revenue
Merchandising operations
5 Inventory and Cost of Goods Sold
A merchandising company buys and sells inventory. Inventory is a current asset on the balance sheet.
Selling this inventory moves its cost to the cost of goods sold (COGS) on the income statement.
There are several inventory methods that determine cost of goods sold:
- specific identification
- first-in, first-out (FIFO)
- last-in, first-out (LIFO)
- weighted average

6 Cash and Internal Control
This lesson focuses on three topics:
- cash and cash equivalents
- bank reconciliation
- fraud
- internal control
Cash includes coins, currency, demand deposits, and similar assets.
Cash equivalents include short-term liquid items that mature in three months or less. To be a cash equivalent, the investments must have a low risk of change in value.
A bank reconciliation serves as a verification tool. It ensures that the cash balances presented in a company’s books match the balances reported by the bank.
Fraud is knowing deception for financial gain. There are three infamous financial frauds in the 21st century:
- Enron
- WorldCom
- Bernie Madoff
Internal control is a system in accounting and auditing to protect assets and financial records. It is required to comply with legal requirements and improve the company efficiency.

7 Accounting for Receivables
Receivables are promises to pay from another entity. Receivables are assets on the balance sheet. There are several types of receivables:
- accounts receivable
- notes receivable
- interest receivable
Accounts receivable should be recorded at the amount the company expects to collect. This amount is called the net realizable value.
For example, if the accounts receivable balance is $50,000 but the company expects that $1,000 will not be paid, the net realizable value is $49,000. The $1,000 represents bad debts or uncollectible accounts.
There are two methods to account for bad debts:
1. Allowance method
2. Direct write-off method

8 Accounting for Long-Term Assets

- plant assets

25 Time Value of Money
The time value of money is a foundational concept in finance. There are two ways to calculate time value of money:
- simple interest
- compound interest
Simple interest pays interest only on the principal, not on the accrued interest. It is the easiest interest to calculate.
The simple interest formula is Interest = Principal x Rate x Time, or I = PRT.
Compound interest pays interest on both principal and accrued interest.
Time value of money includes several formulas using compound interest:
- future value formula
- present value formula
- future value of an annuity formula
- present value of an annuity formula
- future value of an annuity due formula
- present value of an annuity due formula
These time value of money formulas use the following variables to calculate the TVM problems:
- FV: future value is a lump sum at a future date
- PV: present value is a lump sum at the current date
- r: periodic rate of return; some formulas use i for interest instead of r
- PMT: payment is an annuity or a stream of equal payments (+ or -) at equal intervals
- N: number of periods; number of years times the periods per year
