The four-column habit review
Record money and active time, then note energy and stress without turning them into a score.
Four columns, two different kinds of information
Money records what you paid. Time records active minutes within a boundary you choose. Energy and stress record your own impressions. The first two are numerical quantities; the last two are subjective indicators. None should be combined into one total or used to diagnose a health condition.
This is CostlyHabits' practical explanatory framework. It has not been validated in a study. Its value is that you can inspect the assumptions and repeat the exercise yourself, with a notebook if you prefer.
Run a seven-day review
Choose one routine and define where it begins and ends. For seven days record each occurrence, the payment, active minutes, an optional energy note and an optional stress note. Mark unknown amounts as estimates. Record a zero only when it really is zero; leave missing information labeled missing.
- Count an expense once: allocate ingredients to meals or use the whole shopping receipt, not both in the same total.
- Do not count the same minute twice for simultaneous tasks. Distinguish active work from waiting or unattended cooking.
- Keep essential commitments, access needs and household responsibilities visible.
- Compare a feasible replacement with the current routine, including replacement costs and additional work.
- Choose one reversible change, keep a fallback, and review another comparable week.
How to interpret a complete example
The lunch walkthrough follows seven hypothetical days, totals $57 and 70 active minutes, and compares replacing one $13 lunch with a $4 alternative requiring three more active minutes. The modeled week becomes $48 and 73 minutes. The exercise keeps a valued social meal and a useful delivery rather than treating all convenience as waste.
Subjective observations help explain what a choice demanded, but they do not prove that the routine caused tiredness or stress. One week may miss annual bills, illness, holidays or unusual work patterns. Use a second comparable week before relying on a long-term projection.
Use the method without an account
Download the blank CSV, open it in a spreadsheet or copy the columns onto paper. For a paper copy use your spreadsheet's print function. Keep the completed record privately; no upload, email signup or personal-data submission is required. The calculator totals only distinct monthly money estimates, while the monthly worksheet helps reconcile actual changes.
