Your own three statements
You have a balance sheet, an income statement and a cash flow too. Portfolio keeps all three.
Your balance sheet: net worth
Everything you own (investments, cash, a home) minus everything you owe (loans, cards). Portfolio shows it on Overview.
Your income statement: what you keep
Pay and dividends in; spending, fees and interest out. What is left is what you can save and invest.
Your cash flow: the calendar
Salary day, loan payments, card bills and dividends, in date order. Portfolio's Upcoming card shows what is about to move.
Why bother
Most money trouble is a cash flow problem first: a bill arrives before the money does. Seeing your own three reports makes the next step obvious.
