monthly budget = weekly baseline × 52 ÷ 12

Reproducible steps

  1. 1.Average at least four normal shopping weeks.
  2. 2.Separate groceries from restaurants and household supplies.
  3. 3.Apply one realistic adjustment, then review the result against actual receipts.

Data note — Evergreen model: The formula works with your own inputs and does not depend on a specific price or year.
