TL;DR

The accounting equation (Assets = Liabilities + Equity) is the foundation — every transaction must keep it balanced
Debits and credits aren't "good" and "bad" — they're just left and right sides of an account
T-accounts are your best tool for visualizing how transactions affect individual accounts
Financial statements tell a story: the income statement shows performance, the balance sheet shows position, the cash flow statement shows... cash flow

Accounting is one of those subjects where students either get it quickly or stare at their textbook in total confusion. There doesn't seem to be much middle ground.

If you're in the confused camp, don't panic. Accounting isn't about being a "numbers person." It's about learning a system — a specific, logical system for tracking money. Once the system clicks, everything else is just application.

The problem? Most accounting textbooks explain the system in the most boring, abstract way possible. Let's try a different approach.

The Accounting Equation: Everything Starts Here

Assets = Liabilities + Equity

This is the foundation of ALL accounting. Every single transaction, every journal entry, every financial statement — it all comes back to this equation staying balanced.

Let's break it down:

Assets = What the company OWNS (cash, equipment, inventory, buildings, accounts receivable)

Liabilities = What the company OWES (loans, accounts payable, wages payable, bonds)

Equity = What's left for the owners (owner's investment + retained earnings)

Think of it like buying a house:

The house (asset) costs $300,000
Your mortgage (liability) is $250,000
Your equity (what you actually "own") is $50,000
$300,000 = $250,000 + $50,000 ✓

Every transaction affects this equation, but it ALWAYS stays balanced. If assets go up, either liabilities go up, equity goes up, or another asset goes down by the same amount.

Debits and Credits: The Most Confusing Part

This is where most students get stuck. Let's demystify it.

Forget What You Think You Know

In everyday language, "debit" sounds negative and "credit" sounds positive. Forget that completely. In accounting:

Debit = LEFT side of an account
Credit = RIGHT side of an account

That's it. No good, no bad. Just left and right.

The Rules

Different account types increase on different sides:

Account Type	Increases With	Decreases With	Normal Balance
Assets	Debit (left)	Credit (right)	Debit
Liabilities	Credit (right)	Debit (left)	Credit
Equity	Credit (right)	Debit (left)	Credit
Revenue	Credit (right)	Debit (left)	Credit
Expenses	Debit (left)	Credit (right)	Debit

The Memory Trick: ADE / LER

Assets, Drawings (withdrawals), Expenses → Debit to increase Liabilities, Equity, Revenue → Credit to increase

Or think of it by the accounting equation:

Left side (Assets) → increases on the left (debit) Right side (Liabilities + Equity) → increases on the right (credit)

Revenue increases equity (good for owners) → credit Expenses decrease equity (cost to owners) → debit

Why This Makes Sense

Every transaction has two sides (double-entry accounting). If cash (an asset) increases, something else must change to keep the equation balanced:

Example: You receive $1,000 from a customer

Cash (asset) increases → Debit Cash $1,000
Revenue increases → Credit Revenue $1,000

Both sides of the equation go up by $1,000. Assets increased, equity increased (through revenue). Balanced.

Example: You pay $500 for rent

Rent Expense increases → Debit Rent Expense $500
Cash (asset) decreases → Credit Cash $500

Expenses go up (debit), cash goes down (credit). Total debits = total credits. Balanced.

T-Accounts: Your Visual Best Friend

A T-account is a visual tool that shows debits (left) and credits (right) for a single account. It literally looks like a T:

         Cash
   ──────────────────
  Debit    |   Credit
  ─────────|─────────
  1,000    |    500
  2,000    |    300
  ─────────|─────────
  3,000    |    800
           |
  Balance: 2,200 (Debit)

How to use T-accounts:

Draw a T for each account affected
Put the account name above the T
Record debits on the left, credits on the right
Calculate the balance (larger side minus smaller side)

T-accounts make journal entries visual. When you're confused about a transaction, drawing T-accounts almost always makes it clearer.

Journal Entries: Recording Transactions

Journal entries are how you formally record transactions. Every entry must have:

A date
At least one debit and one credit
Total debits = total credits
A brief description

Format

Date    Account Name                    Debit     Credit
────────────────────────────────────────────────────────
Jan 1   Cash                            5,000
           Owner's Capital                          5,000
        (Owner invested cash in business)

Common Journal Entry Examples

Owner invests $10,000 cash:

Cash                    10,000
    Owner's Capital              10,000

(Asset up, Equity up)

Purchase equipment for $3,000 cash:

Equipment               3,000
    Cash                         3,000

(One asset up, another asset down — total assets unchanged)

Purchase supplies on credit ($500):

Supplies                   500
    Accounts Payable               500

(Asset up, Liability up)

Receive $2,000 from performing services:

Cash                    2,000
    Service Revenue              2,000

(Asset up, Revenue/Equity up)

Pay employee wages $800:

Wages Expense              800
    Cash                           800

(Expense up [equity down], Asset down)

Pay off $500 owed to supplier:

Accounts Payable           500
    Cash                           500

(Liability down, Asset down)

The Accounting Cycle

The accounting cycle is the process of recording, organizing, and reporting financial transactions. It happens every accounting period (usually monthly, quarterly, or annually).

The Steps

Identify and analyze transactions — Something happened, figure out which accounts are affected
Record in the journal — Create journal entries (debits and credits)
Post to the ledger — Transfer journal entries to individual account T-accounts
Prepare a trial balance — List all accounts and their balances; total debits should equal total credits
Make adjusting entries — Record accruals, deferrals, and corrections at period end
Prepare adjusted trial balance — Update the trial balance with adjusting entries
Prepare financial statements — Income statement, then balance sheet, then cash flow
Close temporary accounts — Reset revenue, expense, and drawing accounts to zero for next period
Prepare post-closing trial balance — Verify only permanent accounts remain

Adjusting Entries (The Tricky Part)

At the end of each period, you need adjusting entries for things that don't get recorded in daily transactions:

Accrued revenue: Money earned but not yet received

Accounts Receivable       500
    Service Revenue               500

Accrued expenses: Expenses incurred but not yet paid

Wages Expense             300
    Wages Payable                 300

Prepaid expenses (using up): Insurance you already paid for

Insurance Expense         100
    Prepaid Insurance             100

Depreciation: Allocating the cost of equipment over its useful life

Depreciation Expense      200
    Accumulated Depreciation      200

Unearned revenue (earning it): Money received in advance for services now performed

Unearned Revenue          400
    Service Revenue               400

Financial Statements: The Final Product

Everything you've been doing leads to three main financial statements:

1. Income Statement (Performance)

Shows revenue minus expenses for a specific period.

Revenue                          $50,000
Less: Expenses
  Wages Expense      $20,000
  Rent Expense       $ 5,000
  Utilities Expense  $ 2,000
  Depreciation       $ 1,000
  Total Expenses                 $28,000
                                 ────────
Net Income                       $22,000

Key point: Net Income flows into the equity section of the balance sheet through Retained Earnings.

2. Balance Sheet (Position)

Shows assets, liabilities, and equity at a specific point in time.

ASSETS
  Cash                     $15,000
  Accounts Receivable      $ 8,000
  Equipment                $20,000
  Less: Accum. Depreciation ($ 3,000)
  Total Assets             $40,000

LIABILITIES
  Accounts Payable         $ 5,000
  Notes Payable            $10,000
  Total Liabilities        $15,000

EQUITY
  Owner's Capital          $25,000
  Total Liabilities + Equity $40,000

Key point: Assets = Liabilities + Equity. Always. If it doesn't balance, there's an error.

3. Cash Flow Statement (Cash Movement)

Shows where cash came from and where it went, organized into three categories:

Operating activities: Cash from running the business (the main thing)
Investing activities: Cash from buying/selling long-term assets
Financing activities: Cash from borrowing, repaying loans, or owner investments/withdrawals

Common Accounting Homework Mistakes

Mistake 1: Debiting When You Should Credit (and Vice Versa)

Fix: Always ask yourself two questions:

What type of account is this? (Asset, Liability, Equity, Revenue, Expense)
Is it increasing or decreasing?

Then check the chart: Assets and Expenses increase with debits. Everything else increases with credits.

Mistake 2: Unbalanced Entries

Fix: After every journal entry, verify total debits = total credits. This should be automatic. If they don't balance, find the error before moving on.

Mistake 3: Forgetting Adjusting Entries

Fix: At period end, always check for:

Revenue earned but not recorded
Expenses incurred but not recorded
Prepaid items that have been used up
Depreciation on fixed assets
Unearned revenue that's been earned

Mistake 4: Mixing Up the Income Statement and Balance Sheet

Fix: Income statement shows a PERIOD (revenue and expenses over time). Balance sheet shows a POINT IN TIME (what you have and owe right now). Revenue and expense accounts go on the income statement. Asset, liability, and equity accounts go on the balance sheet.

Mistake 5: Arithmetic Errors

Fix: Use a calculator. Seriously. And double-check your additions. More accounting errors come from simple math mistakes than from conceptual misunderstandings.

Study Strategies for Accounting

1. Practice, Practice, Practice

Accounting is procedural. Like math, you can't learn it by reading — you have to do problems. Work through textbook exercises, homework, and additional practice sets until the process becomes automatic.

2. Use T-Accounts for Everything

Whenever you're confused, draw T-accounts. They make abstract debits and credits visual and concrete.

3. Trace Transactions Through the Full Cycle

Don't just do journal entries in isolation. Practice taking a set of transactions through the entire cycle: journal → ledger → trial balance → financial statements.

4. Learn the Concepts Before the Procedures

Understand WHY debits and credits work the way they do (keeping the equation balanced) before trying to memorize which accounts get debited and credited.

5. Use AI for Concept Checks

When a transaction confuses you, describe it to Gradily and ask which accounts are affected and why. AI is great at explaining accounting logic step by step.

6. Make Flashcards for Account Types

Create cards that test whether specific accounts are assets, liabilities, equity, revenue, or expenses, and whether they have normal debit or credit balances.

The Bigger Picture

Accounting isn't just about passing a class (though that's important right now). It's the language of business. Every company, every nonprofit, every government entity uses accounting to track and communicate its financial reality.

Understanding accounting gives you the ability to:

Read financial statements and understand what they mean
Make informed personal financial decisions
Understand business news and economic reporting
Pursue careers in business, finance, consulting, or entrepreneurship

The system is logical. The rules are consistent. And once it clicks, it stays clicked. Give it time, do the practice problems, and use your resources (textbook, professor, AI tools, study groups) when you're stuck.

Every accountant started exactly where you are: staring at debits and credits wondering why left and right matter so much. It gets better. Keep going.
