What is double-entry bookkeeping?
Double-entry bookkeeping records every transaction in two places at once. It tracks both "where money came from" and "where it went."
For example, buying coffee:
- Expense: Food & Drink +$4.50 (where money was spent)
- Asset: Cash -$4.50 (where money left)
By recording both sides, you can see exactly how your money flows.
Why does it matter for personal finance?
Simple bookkeeping only records "how much you spent." Double-entry also tracks:
- Credit card payments = increasing debt
- Salary deposits = which account received it
- Card bill payments = debt decrease + asset decrease simultaneously
This lets you track your net worth (assets - liabilities) in real time.
