Food is typically the third-largest household expense after housing and transportation. Unlike fixed costs such as rent or a mortgage, grocery spending is highly variable and offers significant opportunities for savings without sacrificing nutrition. The key is finding a budget that balances nutritional quality, convenience, and cost for your specific household composition and dietary needs.

A practical benchmark is the USDA food plan scale, which provides estimates ranging from thrifty to liberal spending per person per week. For a moderate plan, adults typically spend $60 to $90 per week on groceries. Families with young children often spend less per person because children eat smaller portions, while teenagers can push per-person costs higher. Comparing your actual spending to these benchmarks helps identify whether you are overspending or already running an efficient kitchen.

The simplest ways to reduce grocery costs include meal planning to avoid food waste, buying store brands instead of name brands, shopping sales and using coupons strategically, buying in bulk for non-perishable staples, and reducing dining out. Cooking at home costs a fraction of eating out. A home-cooked meal typically costs $2 to $5 per serving, while the average restaurant meal costs $13 to $20 per person. Even small shifts from dining out to cooking at home can save thousands of dollars annually.
