Double Entry Accounting Calculator

Double-entry accounting records every transaction in at least two accounts: one is debited, another is credited, and the totals always balance. This is not accounting tricks — it reflects an algebraic truth: Assets = Liabilities + Equity. Every transaction affects both sides of this equation in ways that keep it balanced.

Debits and credits do not mean “good” and “bad.” They are directions:

• Debits increase assets and expenses, decrease liabilities, equity, and revenue
• Credits do the opposite

A common mnemonic: DEAD CLIC. Debits increase Dividends, Expenses, Assets, Drawings. Credits increase Liabilities, Income, Capital.

For example, buying equipment with $5,000 cash: debit Equipment $5,000 (asset goes up), credit Cash $5,000 (asset goes down). Both are asset accounts, so the equation stays balanced — assets just shift form. No net change to liabilities or equity.

Contrast that with taking a loan: debit Cash $5,000 (asset up), credit Loan Payable $5,000 (liability up). Now both sides of the equation increase by the same amount. The balance holds.

Revenue collected in cash: debit Cash (asset up), credit Revenue (equity up). Both sides increase. Paying an expense with cash: debit Expense (equity down), credit Cash (asset down). Both sides decrease.

The journal entry is always the first step. From there, entries flow to the ledger, then to trial balance, then to financial statements. Getting the debit/credit direction right at this stage prevents cascading errors all the way up the reporting chain.
