How the Calculator Works

- Pantry = Grains, pasta, rice, canned goods, spices, oils
- Snacks = Chips, cookies, beverages, coffee, tea

The calculator adjusts estimates based on household size, dietary preferences, and eating out frequency to provide personalized budget recommendations.
Key Concepts Explained
Per Person Cost
Average grocery spending is $250-$350 per person monthly. Children typically cost 60-80% of adult food expenses depending on age.
Dietary Impact
Organic diets cost 20-50% more, while vegetarian diets can save 10-30% on protein costs compared to standard meat-based diets.
Shopping Frequency
Weekly shopping reduces food waste but increases impulse purchases. Monthly bulk buying saves 10-15% but requires storage space.
Eating Out Impact
Each meal eaten out reduces grocery costs by $8-15 per person but increases overall food spending by 2-3x compared to home cooking.
