Best Ways to Save Money on Groceries

The short answer: a family of four can feed itself on the USDA thrifty food plan for about $1,025 a month as of July 2026. The benchmark comes from the USDA Food and Nutrition Administration's official food plan tables, which the agency updates monthly against the Consumer Price Index. The verified levers that move the number are store brands, cooking at home, planning around food waste, and unit pricing, with the figures behind each one below.

What the USDA says a family should spend on food

The USDA Food and Nutrition Administration publishes four food plan levels each month: thrifty, low-cost, moderate, and liberal. Each plan is a market basket designed to meet federal nutrition guidelines, priced at grocery-store level using Consumer Price Index data. Monthly figures are the weekly cost times 4.333, and the full table updates every month. In the July 2026 report, the reference family of four (two adults ages 20 to 50 plus two children) could cover the thrifty plan at $236.50 a week, or $1,024.90 a month (page updated August 26, 2026; USDA Food and Nutrition Administration).

The low-cost, moderate, and liberal totals are derived by summing the four published member costs in the same July 2026 tables (USDA Food and Nutrition Administration). The thrifty plan is the minimum the federal government says a family of four can spend and still buy a nutritious market basket, which makes it the most practical planning number for a household that needs to cut food spending. None of the plans are spending advice; they are benchmarks of what groceries must cost, and they move with the CPI every month.

How to size the number for your household

The USDA publishes a clear household-size adjustment to go with the tables. Use the printed plan as published, add 20% for a one-person household, add 10% for a two-person household, add 5% for a three-person household, use the figure as printed for four people, subtract 5% for households of five to six people, and subtract 10% for households of seven or more (USDA Food and Nutrition Administration, July 2026 food plan report). The adjustment exists because packaging, portions, and cooking losses do not scale in a straight line; smaller households generally pay more per plate than the printed per-member cost suggests.

A single adult starts from the printed member cost and adds 20%; a couple adds 10%; a family of five subtracts 5%. Run the arithmetic on the current month's table, since the CPI moves all four levels monthly (USDA Food and Nutrition Administration, July 2026).

Single adults: use the member tables

For a single adult between the ages of 20 and 50, the July 2026 thrifty cost is $58.60 a week for a female and $73.70 a week for a male, which works out to about $253.90 and $319.20 a month. The low-cost level is $63.70 a week for a female and $73.30 a week for a male, about $276.10 and $317.40 a month (USDA Food and Nutrition Administration, July 2026). Apply the 20% single-person add-on from the household-size rule before budgeting from these numbers.

A note on these tables: the USDA prices each member cost inside a four-person household context, so the weekly figures are a starting point, and the household-size adjustment turns them into a personal target. Track your grocery line for one month and compare it with the adjusted thrifty number; the USDA benchmark tells you whether your spending is high, low, or on the government standard.

What grocery inflation looks like right now

Grocery inflation is real but generally slower than the restaurant number. For the 12 months ending July 2026, food at home rose 2.7%, food away from home rose 3.4%, and all food rose 3.0%, with fruits and vegetables up 5.1%, according to the Bureau of Labor Statistics Consumer Price Index news release USDL-26-1378 of August 12, 2026. The produce line matters if your basket is vegetable-heavy; the food at home average overstates it if you mostly buy shelf-stable items.

The deeper fact is where food dollars go. Food away from home was 56.3% of total US food spending in 2025, with food at home at about $1.10 trillion and food away from home at about $1.41 trillion out of a $2.51 trillion total, per the USDA Economic Research Service Food Expenditure Series (Charts of Note, June 11, 2026). When more than half of a family's food spending leaves the grocery line, moving a few meals a week back to the kitchen is a lever worth more than any coupon roundup.

Tactic 1: Buy store brands

Store brands are the most generalizable saving in the grocery store. Industry-group figures from the Private Label Manufacturers Association, based on Circana data, put the typical saving at about 20% to 25% below national brand prices and report that US consumers saved about $35 billion on store brands in 2025, at a record 21.3% dollar share. These are trade-association numbers, not an independent audit, and they describe averages rather than every single item. Even so, the everyday gap on shelf-stable goods, dairy, eggs, and frozen produce is large enough that switching a cart of staples is the fastest structural change most households can make.

Test two or three categories at once: buy store brands of the canned goods, milk, and frozen vegetables you use weekly, and compare with last month's receipts. Where ingredient lists and nutrition panels are close, the risk is small, and the compounding effect is what keeps the $1,024.90 thrifty benchmark reachable (PLMA Store Brand Facts, Circana data).

Tactic 2: Use unit pricing

Unit pricing prints the cost per ounce, pound, or liter so that package size cannot hide the true cost. A 2025 NIST study (Special Publication 1181, June 2025) found that 74% of shoppers use unit pricing when stores provide it, and that 16 states have unit-pricing regulations on the books. Unit price works best for shelf-stable staples that you buy on every trip, and it is the tool behind the package-size rule of thumb in our guide to how much you should spend on groceries per month.

Tactic 3: Cook at home and plan meals

Cooking at home is the tactic with the biggest dollar base. Because food away from home accounted for 56.3% of US food spending in 2025, a household that moves just a few meals a week from restaurants or takeout to the kitchen redirects real money into the grocery line, where the USDA benchmarks apply (USDA Economic Research Service, June 11, 2026). Meal planning turns the trip into a list built from meals you already chose, cutting impulse buys and the reflex to reorder instead of plating leftovers. For the money questions that surround the food bill, our guide to what to do with extra money each month starts where the grocery line ends.

Tactic 4: Plan around food waste

Wasted food is purchased food, so reducing waste is the only saving that does not change what you eat. The USDA estimates that 30% to 40% of the US food supply is lost or wasted, based on its finding that about 31% of food is lost at retail and consumer levels, roughly 133 billion pounds and $161 billion in its 2010 estimates; the EPA restated the 30% to 40% range on December 4, 2025 (USDA, food waste FAQs). On a personal scale the fix is routine: buy what you will actually eat, freeze surplus before it turns, cook leftovers into the next meal, and shop again only when the fridge is thin.

The freezer does a lot of the work here. Portioning meat, bread, and cooked grains into frozen servings on shopping day turns a perishable purchase into a shelf-stable one, and a packed freezer also reduces the chance that a busy evening ends in a restaurant order. Under the USDA estimate, a family that reclaims even a modest slice of the 30% to 40% national loss is cutting real dollars without changing the menu.

Tactic 5: Compare package sizes and forms

Fresh produce is not automatically the cheapest form. The USDA Economic Research Service noted in Charts of Note (March 28, 2016) that canned corn and frozen raspberries have, at times, cost less than their fresh counterparts, and that the answer depends on the item. Compare canned, frozen, and fresh by unit price instead of assuming fresh wins, and remember that the cheapest form is the one your household actually finishes: a bag that spoils costs more than a can that stores (USDA Economic Research Service).

A weekly system that follows the data

• Shop once or twice a week from a list built around planned meals, not weekly ads.
• Track unit prices for the five to ten staples your household buys most.
• Switch the highest-frequency staples to store brands and measure the gap yourself.
• Cook one more dinner at home than you did last week.
• Use or freeze leftovers before the next shopping trip.

The system works because each item carries a verified number: store brands at a 20% to 25% gap on industry data, unit pricing used by 74% of shoppers where offered, and a 30% to 40% food waste estimate that sets the upper bound of what careful planning can reclaim (PLMA, NIST, USDA). If you want the target in writing, the adjusted USDA thrifty number doubles as a spending line, and our roundup of the best free budget spreadsheet templates can carry it from month to month.

Government programs that lower the grocery bill

For households that qualify, SNAP is the largest direct offset. In fiscal year 2026 (October 1, 2025 to September 30, 2026), the maximum monthly allotment for a family of four is $994, and the gross income limit for a family of four is $3,483 a month, which is 130% of the federal poverty level (USDA Food and Nutrition Service, SNAP cost-of-living adjustment, updated April 27, 2026). SNAP benefits are not taxable income, and an allotment that large covers most of the $1,024.90 thrifty benchmark. For broader strategies on a tight income, see our guide to best ways to save money on a low income.

WIC covers a more specific slice: pregnant and postpartum women, infants, and children under age 5. A family of four qualifies at 185% of the federal poverty guidelines, which is $61,050 a year, or $5,088 a month, for the period July 1, 2026 through June 30, 2027 (USDA Food and Nutrition Service, WIC income guidelines, Federal Register notice 2026-08323, April 29, 2026). WIC purchases are limited to approved foods and formula, so for eligible households the effect is a direct reduction in the formula, milk, cereal, and produce lines rather than flexible cash. The programs stack: eligible households can draw both SNAP and WIC.

How we reported this

We built this guide from primary sources rather than roundup posts, and every number below is dated and linked. Spending benchmarks come from the USDA Food and Nutrition Administration's cost of food monthly reports (July 2026, updated August 26, 2026); inflation from the Bureau of Labor Statistics CPI news release USDL-26-1378 (August 12, 2026); spending shares from the USDA Economic Research Service Charts of Note (June 11, 2026); and program rules from the SNAP cost-of-living adjustment page (April 27, 2026) and the WIC income guidelines notice (April 29, 2026). The PLMA store-brand figures are trade-association data based on Circana, labeled as such rather than as an independent audit, and estimates are marked as estimates in the text.

You do not need a coupon binder or a premium rewards card to cut the grocery bill. The verified levers are boring on purpose: buy store brands, price by unit, cook at home, and plan around waste. The USDA benchmarks tell you what the bill should be for your household size, and the saving follows the system rather than the discount of the week.
