ACCT 3
Lesson Topic: Double-entry bookkeeping
I. Debit and Credit entries
-In accounting, Debit (Dr) and Credit (Cr) are the two sides used to record every transaction.
Evevry account/transaction have debits and credits
. Debit: an entry on the left side of an account.
. Credit: an entry on the right side of an account.
⭐ Debit & Credit Cheat Sheet
Account | Debit (Dr) | Credit (Cr) |
|---|---|---|
Asset | ⬆ Increase | ⬇ Decrease |
Expense | ⬆ Increase | ⬇ Decrease |
Liability | ⬇ Decrease | ⬆ Increase |
Owner's Equity/Capital | ⬇ Decrease | ⬆ Increase |
Revenue/Income | ⬇ Decrease | ⬆ Increase |
🧠 Remember this:
DEBIT: Assets ↑, Expenses ↑
CREDIT: Liabilities ↑, Equity ↑, Revenue ↑
total Debit always = total Credit
Cash comes in → Debit Cash ✅
Cash goes out → Credit Cash ✅
But:
Revenue comes in → Credit Revenue ✅
The easiest rule to memorize:
Account | When it increases |
|---|---|
Asset | ➡ Debit |
Expense | ➡ Debit |
Liability | ➡ Credit |
Owner's Equity | ➡ Credit |
Revenue | ➡ Credit |

1. Know the 5 types of accounts
Every transaction affects one or more of these:
Account | What it means | Example |
|---|---|---|
Asset | What the business owns | Cash, equipment, supplies |
Liability | What the business owes | Loan, Accounts Payable |
Owner's Equity | Owner's claim in the business | Capital |
Revenue | Money earned from business activities | Sales, Service Revenue |
Expense | Costs of running the business | Rent, salary, electricity |
Easy examples
Cash → Asset
Equipment → Asset
Loan → Liability
Capital → Equity
Sales → Revenue
Rent → Expense
2. Understand Debit and Credit
Don't think of debit as "good" and credit as "bad."
They simply mean:
Debit (Dr) = LEFT side
Credit (Cr) = RIGHT side
Every transaction has both.
⭐ The most important rule:
Assets + Expenses increase → Debit
Liabilities + Equity + Revenue increase → Credit
You can memorize:
A + E = Debit
L + E + R = Credit
3. Understand that accounts can increase OR decrease
For example, Cash is an asset.
If you receive $1,000:
Cash increases → Debit
If you pay $500:
Cash decreases → Credit
So:
Cash (Asset) | |
|---|---|
Debit ↑ | Credit ↓ |
This applies to assets:
Asset ↑ = Debit
Asset ↓ = Credit
4. Understand the double-entry concept
This is the main idea of Lecture 3.
Every transaction affects at least two accounts.
And:
Total Debit = Total Credit ✅
Example:
You buy equipment for $3,000 cash.
Two things happen:
Equipment increases → Debit Equipment $3,000
Cash decreases → Credit Cash $3,000
Account | Debit | Credit |
|---|---|---|
Equipment | $3,000 | |
Cash | $3,000 | |
Total | $3,000 | $3,000 |
✅ Balanced!
5. Learn how to analyze a transaction
Before deciding Dr or Cr, ask yourself 3 questions:
Question 1: What accounts are affected?
Question 2: What type of accounts are they?
Question 3: Did they increase or decrease?
Then choose Debit or Credit.
Example:
Business pays $1,000 rent in cash.
Step 1: What accounts?
→ Rent Expense
→ Cash
Step 2: What types?
→ Rent = Expense
→ Cash = Asset
Step 3: Increase or decrease?
→ Expense increases → Debit
→ Cash decreases → Credit
Therefore:
Dr Rent Expense $1,000
Cr Cash $1,000
6. Understand the Accounting Equation
You learned this before:
Assets = Liabilities + Owner's Equity
And your Debit/Credit system must keep everything balanced.
For example:
Owner puts $5,000 into the business.
The business gets:
Cash +$5,000 → Asset increases
The owner's investment creates:
Capital +$5,000 → Equity increases
So:
Assets $5,000 = Equity $5,000 ✅
⭐ Your ACCT 201 cheat sheet
Write this somewhere because you'll use it constantly:
ACCOUNT TYPES
A = Assets → Cash, Equipment, Supplies
L = Liabilities → Loan, Accounts Payable
E = Equity → Capital, Drawings
R = Revenue → Sales, Service Revenue
E = Expenses → Rent, Salary, Utilities
WHEN THEY INCREASE
DEBIT ↑ | CREDIT ↑ |
|---|---|
Assets | Liabilities |
Expenses | Equity |
Revenue |
WHEN THEY DECREASE
DEBIT ↓ | CREDIT ↓ |
|---|---|
Liabilities | Assets |
Equity | Expenses |
Revenue |
And ALWAYS:
TOTAL DEBIT = TOTAL CREDIT ✅
II. Account balances: opening and closing balance
1. How to close off an account
At the end of an accounting period, we calculate the balance remaining in an account.
The basic idea is:
Opening balance + increases − decreases = ending balance
For example:
Opening cash = $2,000
Money received = +$15,000
Money paid = −$1,100
Capital received = +$2,000Ending cash = $17,900
Practice 1
We need to find the trial balance total on the DEBIT side.
Remember the basic rule:
Debit accounts
Expenses
Purchases
Assets
Credit accounts
Capital
Sales
Let's classify each:
Account | Amount | Debit/Credit |
|---|---|---|
Rent expense | $1,800 | Debit |
Capital | $15,000 | Credit |
Purchases | $10,000 | Debit |
Sales | $12,000 | Credit |
Wages | $5,000 | Debit |
Sundry expenses | $1,000 | Debit |
Cash | $9,200 | Debit |
Now add the debit side:
$1,800 + $10,000 + $5,000 + $1,000 + $9,200
= $27,000
✅ Answer: D. $27,000
Easy way to remember
Debit = Expenses + Purchases + Assets
So:
Rent + Purchases + Wages + Sundry expenses + Cash
= $27,000
Practice 2
This one is about a Cash account.
Given:
Opening cash = $2,000
Payments by customers = +$15,000
Rent paid = −$250
Insurance paid = −$150
Drawings = −$700
Capital paid in = +$2,000
Step 1: Start with opening balance
$2,000
Step 2: Add money coming IN
Payments by customers:
+$15,000
Capital paid in:
+$2,000
So:
$2,000 + $15,000 + $2,000 = $19,000
Step 3: Subtract money going OUT
Rent:
−$250
Insurance:
−$150
Drawings:
−$700
Total paid out:
$250 + $150 + $700 = $1,100
Step 4: Find ending balance
$19,000 − $1,100 = $17,900
✅ Balance at 31 March =
Credit (money OUT)
Balance b/f
2,000
Rent
Payments by customers
15,000
Insurance
Capital
2,000
Drawings
Balance c/f
17,900
Total
36,900
Total
⭐ Bal b/f means Balance brought forward.
It is simply the balance from the previous period that is brought into the new period.
Example:
At the end of March:
Balance c/f = $17,900
Then at the beginning of April:
Balance b/f = $17,900
So:
c/f = carried forward → end of the period
b/f = brought forward → beginning of the next period
🧠 Easy way to remember
b/f = beginning → money/balance brought from before
c/f = closing → balance carried to the next period
⭐c/f means “carried forward.”
It is the ending balance of an account that is carried to the next accounting period.
Simple example:
You have $2,000 cash at the end of March.
In your March Cash Account:
Balance c/f = $2,000
Then when April starts:
Balance b/f = $2,000
🧠 Remember:
c/f = carried forward → ENDING balance
b/f = brought forward → BEGINNING balance
