  "description": "The USDA publishes monthly food plan estimates at four spending tiers — Thrifty, Low-Cost, Moderate, and Liberal — broken out by age and sex, which is the most defensible public benchmark for grocery budgeting available. This calculator applies representative per-person monthly costs at each tier, adjusted for kids' ages (young children eat less than teenagers, who often eat more than adults), and totals them into a household grocery budget so you have a real number to compare against your actual spending instead of a guess.",
  "formula": "Household budget = sum of per-person monthly cost at chosen tier, where child costs scale by age band relative to adult cost.",

    {
      "q": "What do the USDA spending tiers actually mean?",
      "a": "Thrifty is the basis for SNAP benefit calculations and assumes almost all meals cooked from scratch with minimal waste. Liberal assumes more convenience foods, name brands, and less price-consciousness. Most middle-income families land between Low-Cost and Moderate in practice."

    {
      "q": "Why do teenagers cost more to feed than adults in some models?",
      "a": "Teen boys in particular have higher caloric needs than the average adult during growth spurts, and USDA data reflects that a 16-year-old often eats more than a sedentary adult. If your teen has a smaller appetite, adjust the tier down manually."
    },
    {
      "q": "Does this include household supplies like paper towels or cleaning products?",
      "a": "No, this is food-only, matching USDA methodology. Add a separate household supplies budget of roughly $40-80/month depending on household size if you want an all-in grocery-trip total."
