Which USDA plan is yours?
Thrifty is the USDA’s lowest-cost nutritious plan; SNAP allotments are based on it. Low-cost is home cooking with a little more variety and convenience. Moderate is the middle cost level among the USDA food plans. Liberal is the top of the USDA range; more convenience and premium choices. If your spend sits above liberal, something structural is at play — convenience food, eating out counted as groceries, or a high-cost city.
Common questions.
Is my grocery bill normal for a family of 4?
Compare it to the moderate column: $1388.73 a month ($320.50/wk) is the USDA’s middle estimate for this household. Being under thrifty ($1023.45) usually means careful planning or missing categories like snacks and household staples.
Are these numbers current?
They are the USDA’s August 2026 food plans, updated monthly for food-price inflation. Food-at-home only — restaurants and delivery are not included.
How do I actually hit the thrifty number?
Plan the week first, buy store brands, and shop a written list. Our $50 dinner week shows what thrifty-adjacent cooking looks like with real prices.
Why do smaller households pay more per person?
The USDA adjusts for scale: a one-person household pays about 20% more per head than a four-person family, because small packages and unshared staples cost more. It is built into the totals above.
