Five habits matter more than a fashionable split.

  1. Choose the household

    Budget for yourself or for the household, but do not mix one person’s income with everybody’s costs.

  2. Use evidence

    Check payslips, statements and real bills. Memory is unusually generous about small spending and unusually vague about annual renewals.

  3. Make irregular costs monthly

    Divide yearly insurance, servicing, school costs, gifts and similar bills by twelve so the calendar does not ambush the budget.

  4. Name the margin

    A positive remainder is not automatically spare. Decide what protects the next month, funds a known goal or stays flexible.

  5. Review, do not restart

    Spend ten minutes comparing plan with reality. Adjust the weak estimate; do not declare the whole budget a moral failure.

Healthy assets can hide a fragile month. A tight month can hide long-term progress.

Cash flow asks whether income covers current outgoings. Net worth asks whether the value of everything owned exceeds everything owed, and how that position changes over time. You need both views; neither rescues bad assumptions in the other.
