How to Estimate Weekly Grocery Cost

Formula

Weekly Cost = (People x Meals/Day x 7 x Cost per Serving) + Snack Budget

Cost per Serving Benchmarks

  • $2-3: Budget-friendly (rice, beans, pasta, seasonal vegetables)
  • $4-6: Moderate (includes meat, varied vegetables, dairy)
  • $7-10: Premium (organic, specialty ingredients, higher meat quality)
  • $10+: Gourmet or specialty diets

    • Saving Tips

    Plan meals around weekly sales. Buy staples in bulk. Cook large batches and portion for multiple meals. Reduce food waste by planning before shopping.

    计算示例

    A household of 4, cooking 2.5 meals per day at $4 per serving, with $20 weekly snacks.

    1. Meal cost = 4 x 2.5 x 7 x $4 = $280
    2. Total = $280 + $20 = $300 per week
    3. Monthly = $300 x 4.33 = $1,299
    4. Per person = $300 / 4 = $75 per week
