One number, two jobs

Net worth = what you own minus what you owe. It tells you whether the household is building. It does not tell you whether you can make rent on Tuesday — that is cash flow and the emergency fund.

Track it the same way each month: cash, investments, retirement, house, cars (depreciated), minus mortgage, student loans, cards, auto loans. The slope matters more than the level until the level is large.

Questions

Do I count my house?

Yes, at a conservative market value, minus the mortgage. Home equity is real and illiquid. Do not live like it is a checking account.
