A quick-reference glossary of core accounting vocabulary — from amortisation and depreciation to working capital and retained earnings.
Why Accounting Vocabulary Matters for Financial Literacy
You don't need a CPA credential to benefit from understanding how accounting works — but you do need a functional vocabulary. Whether you're reviewing a business's balance sheet, evaluating a mortgage, or tracking your own net worth, the same core terms appear repeatedly. Misreading them leads to poor decisions; understanding them sharpens every financial judgment you make.
This reference guide covers the essential accounting terms that form the backbone of financial reporting and analysis. For a deeper walkthrough of how these concepts fit together in practice, see our comprehensive introduction to financial record-keeping. For the standards that govern how these terms are applied in formal financial statements, our plain-language overview of GAAP is a natural companion.

Core Terms: From the Balance Sheet to the Income Statement
The three primary financial statements — the balance sheet, the income statement, and the cash flow statement — each draw on a distinct but overlapping set of terms. Familiarity with the following concepts allows you to extract meaning from any of them.
Accrual Accounting
A method that records revenues and expenses when they are earned or incurred, regardless of when cash changes hands. It is the basis for GAAP-compliant financial statements and gives a more accurate picture of a business's economic activity than cash-basis accounting.
Amortization
The systematic reduction of an intangible asset's value (such as a patent or goodwill) over its useful life, or the scheduled repayment of a loan through regular principal-and-interest installments. Both uses reflect the same underlying idea: spreading a cost or obligation over time.
Depreciation
The allocation of a tangible asset's cost over its useful life, reflecting wear, obsolescence, or passage of time. Common methods include straight-line (equal annual charges) and accelerated approaches such as declining-balance. Depreciation is a non-cash expense that reduces taxable income.
Working Capital
Current assets minus current liabilities. It measures a company's short-term liquidity — its ability to meet near-term obligations with assets that can be converted to cash within one year. Positive working capital generally indicates financial stability; negative working capital signals potential liquidity risk.
Retained Earnings
The cumulative net income a company has kept rather than distributed to shareholders as dividends. Retained earnings appear on the balance sheet under equity and represent the historical profitability that has been reinvested into the business.
Accounts Receivable
Money owed to a business by customers for goods or services already delivered but not yet paid for. Classified as a current asset, accounts receivable represents future cash inflows and is a key component of working capital analysis.
Accounts Payable
Amounts a business owes to suppliers or vendors for goods and services received but not yet paid. It is a current liability on the balance sheet and an important indicator of how a company manages its short-term obligations.
Gross Profit
Revenue minus the cost of goods sold (COGS). Gross profit measures how efficiently a company produces or sources its products before factoring in operating expenses, interest, and taxes. The gross profit margin (gross profit ÷ revenue) is a key profitability metric.
EBITDA
Earnings before interest, taxes, depreciation, and amortization. EBITDA is widely used as a proxy for operating cash flow and for comparing profitability across companies with different capital structures or accounting methods. It is not a GAAP-defined metric and should be interpreted alongside GAAP figures.
Liquidity
The ease with which an asset can be converted into cash without a significant loss in value. Cash is perfectly liquid; real estate is relatively illiquid. In business analysis, liquidity refers to a company's ability to meet short-term obligations.
Book Value
The net value of an asset as recorded on the balance sheet — typically its original cost minus accumulated depreciation (for tangible assets) or amortization (for intangibles). Book value may differ significantly from market value or fair value.
Double-Entry Bookkeeping
The foundational accounting system in which every financial transaction is recorded as both a debit in one account and a corresponding credit in another. This ensures the accounting equation (Assets = Liabilities + Equity) always remains balanced and provides a built-in error-checking mechanism.
Several of these terms also surface in lending and credit contexts. If you encounter amortization in a mortgage document, our mortgage glossary provides a loan-specific breakdown. For personal borrowing more broadly, the loan terminology reference covers the same concept from a borrower's perspective.
Investors should also be aware that many accounting terms carry specific tax implications. For that angle, see key tax terms every investor should understand.
Putting the Terms in Context
Accounting terms rarely appear in isolation — they interact. Net income flows into retained earnings on the balance sheet. Depreciation reduces an asset's book value while also appearing as a non-cash expense on the income statement. Working capital is a ratio derived from current assets and current liabilities.

Core financial statements in GAAP reporting
Every GAAP-compliant set of financials includes a balance sheet, income statement, and statement of cash flows.
2-sided
Every transaction in double-entry bookkeeping
Each transaction generates at least one debit and one credit, keeping the accounting equation perpetually balanced.
Understanding these relationships — not just the individual definitions — is what separates surface-level literacy from genuine financial comprehension. The same vocabulary applies across domains: personal budgeting, real estate (see mortgage concepts), and credit management (see borrowing and debt). For a parallel reference in another domain, our insurance terminology guide applies a similar approach to policy language.
