Accounting equation: does income really decrease equity?
I am new to using [double-entry bookkeeping](https://en.wikipedia.org/wiki/Double-entry_bookkeeping_system) for personal finances. [GnuCash](https://en.wikipedia.org/wiki/GnuCash) uses a variant of [the accounting equation](https://en.wikipedia.org/wiki/Accounting_equation) that has five variables, and which seems to be known colloquially as an "expanded" or "extended" accounting equation: assets - liabilities = equity + (income - expenses) This can be re-arranged as: equity = assets - liabilities - income + expenses Rearranging it in this way shows that, all other things being unchanged, **an *increase* in income results in a *decrease* in equity**. Conversely, **an *increase* in expenses results in a *increase* in equity**. To me, this is totally counter-intuitive. I would have expected (if all else remains unchanged): increased income to *increase* equity; and increased expenses to *decrease* equity. My question is: have I misunderstood the equation or the meaning of the terms; and if so, what is the correct interpretation; or if not, then why is this the correct interpretation?
