Accounting, in the order it actually makes sense to learn it
Ten concepts take you from a single journal entry to a finished set of financial statements. This page shows the order, then points you at the lesson, the calculator or the scenario that covers each part.
Accounting is one idea repeated ten times
Almost everything in financial accounting descends from a single rule: every transaction affects at least two accounts, and the two sides must agree. Once that clicks, the rest of the subject stops being a list of procedures to memorise and becomes a chain, where each step exists only because the previous one produced something that needs organising.
A transaction is recorded as a journal entry. Entries pile up, so they are sorted by account into a ledger. Ledgers need checking, which is what a trial balance does. A verified trial balance is then rearranged into the three statements: the balance sheet for what you own and owe, the profit and loss for what you earned, and the cash flow statement for what actually moved. Everything else on this page is either a refinement of that chain or a check on it.
The order matters more than the volume. People who struggle with accounting have usually met depreciation or inventory valuation before they were comfortable with debits and credits, and concluded the subject is arbitrary. It is not. Follow the map below top to bottom and each concept arrives only when you already have what it needs.
The ten concepts, and what each one is for
These are the ten accounting topics in the study tool, arranged in the order they build on each other rather than alphabetically.
Accounting Basics
The vocabulary and the rules of the game: what an account is, why every entry has two sides, and the difference between recording a transaction and interpreting it.
Journal Entries
The original record. Every transaction enters the books here first, with a debit, a credit and a date, before it is sorted anywhere else.
Ledger and Accounts
The same entries regrouped by account rather than by date, so you can see the running balance of cash, sales or a specific customer.
Trial Balance
The arithmetic check. Total debits must equal total credits. It catches slips of the pen, but not an entry posted correctly to the wrong account.
Balance Sheet
A position at one instant: assets on one side, liabilities and equity on the other. It answers what the business owns and who has a claim on it.
Profit and Loss Statement
A period rather than an instant. Revenue earned less expenses incurred, which is not the same as money received less money paid.
Cash Flow Statement
The reconciliation between the two above. It explains why a profitable business can have an empty bank account, split across operating, investing and financing activity.
Bank Reconciliation
Matching your cash book to the bank statement. The gaps are usually timing, occasionally charges you did not know about, and sometimes an error worth finding.
Depreciation and Amortisation
Spreading the cost of a long-lived asset across the years that use it, so one year does not carry a cost that five years benefit from.
Inventory Valuation
Deciding what your unsold stock is worth. The method you choose changes both the balance sheet and the reported profit, which is why the rules constrain it.
The lessons that teach each of these properly
Accounting for Beginners is the site’s longest course at 33 lessons. These are the ones that map directly onto the concepts above.
The calculators that do this arithmetic for you
Reading a statement is one skill; producing the numbers inside it is another. These tools handle the second.
Where accounting turns into a decision
Comparisons take a distinction that confuses people and settle it with numbers. Scenarios start from a real situation and work forwards.
Test yourself on Accounting
Ten topics with multiple-choice questions, flashcards, word scrambles and crosswords. Accounting is a subject where recall matters, and reading it once is not the same as knowing it.

The Learn page above is the concept map. These are the practical questions readers actually arrive with — a procedure, a decision, a situation with more than one right answer.
