INTRODUCTION

English translation pending.

CORE DEFINITION

The T-account is the visual form of double-entry bookkeeping. Each account is drawn with a debit side on the left and a credit side on the right. Assets and expenses increase on the debit side and decrease on the credit side, while liabilities, equity, and revenue behave in the opposite way. Because every transaction is entered with equal debits and credits, the whole ledger stays in balance, which is why the structure makes the origin and destination of each amount immediately visible.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Use account setup: draw a T for each account with debit left and credit right. - Use rule application: apply the debit and credit rules appropriate to each account type. - Use balance check: total both sides and confirm that the two entries balance exactly.

Anchor fast decisions

Each account is drawn with debits on the left and credits on the right. Assets and expenses increase on the left, while liabilities, equity, and revenue increase on the right, and every transaction records equal debits and credits. That equality keeps the ledger in balance and makes the source and destination of each amount visible.
