Average Grocery Cost for One Person 2026 — USDA Benchmarks & Budget Guide

USDA’s food plans are the standard government benchmark for what a nutritious diet costs. With USDA’s suggested one-person-household adjustment (+20%), the August 2026 figures put groceries for a single adult aged 20–50 at $304–$383 a month on the Thrifty plan and $403–$478 a month on the Moderate-cost plan (female/male). The plans price a healthy diet with every meal and snack prepared at home; they are not a survey of what people actually spend. What you spend depends on where you live, where you shop and what you eat.

Quick answer: For one adult aged 20–50, USDA’s plans range from about $304 a month (Thrifty, female) to $583 (Liberal, male). The Moderate-cost plan, the middle of the range, is about $403–$478 a month, or roughly $93–$110 a week.

USDA Food Plans for a Single Adult (2026)

USDA publishes four food plans at successively higher cost levels — Thrifty, Low-cost, Moderate-cost and Liberal — and updates their costs every month using the Consumer Price Index.

Source: USDA, Thrifty Food Plan and Cost of Food at Home at Three Levels, U.S. average, August 2026, ages 20–50. USDA’s published costs are for individuals in 4-person households; USDA suggests adding 20% for a 1-person household, which is applied here (published monthly cost × 1.2, rounded to the dollar). “Average” is the simple mean of the female and male figures, a wealthvieu calculation, not a USDA figure.

The Thrifty plan is USDA’s lowest-cost plan. Its cost for a reference family of four is what sets the maximum SNAP benefit. The male Thrifty figure comes out slightly above the male Low-cost figure because the plans rest on different data: the Thrifty plan was reevaluated in 2021 and is based on 2013–16 consumption and 2015–16 price data, while the Low-cost, Moderate-cost and Liberal plans are based on 2001–02 data updated for inflation.

Weekly and yearly equivalents

USDA also publishes weekly costs (its monthly figure is the weekly cost × 4.333). With the same 20% one-person adjustment:

Weekly: USDA’s published August 2026 weekly cost × 1.2. Yearly: the adjusted monthly cost × 12. Food prices change every month, so a year’s actual cost will differ.

How Grocery Prices Have Changed Since 2020

BLS’s Consumer Price Index for food at home (U.S. city average) rose from 243.110 in January 2020 to 321.758 in September 2026 — an increase of about 32%. Individual items moved very differently. These are BLS average retail prices for the U.S. city average:

BLS series CUUR0000SAF11, APU0000703112, APU0000708111, APU0000FF1101, APU0000702111, APU0000709112 and APU0000FS1101, not seasonally adjusted. Change is a wealthvieu calculation from the BLS values.

The 2020-to-2026 change hides some big swings. Egg prices rose sharply after an outbreak of highly pathogenic avian influenza that began in 2022 reduced egg-laying flocks and egg production, reaching a BLS average of $6.23 a dozen in March 2025 before falling back to $2.27 in September 2026. Butter peaked at $5.00 a pound in September 2024 and is now near its January 2020 price. Ground beef has risen the most of the items above.

How to Budget for Groceries Living Alone

The USDA figures give a range to plan around, but they assume you cook everything at home, so restaurant and takeout spending comes on top. A few ways to use them:

• Pick the plan closest to how you eat. The Thrifty plan is a tight, cook-everything budget; the Moderate-cost plan allows more variety; the Liberal plan allows more still. Compare your last two or three months of grocery receipts or card statements with the table above.
• Turn it into a weekly number. Most people shop weekly, so the weekly column is easier to track against than a monthly total.
• Check it against your take-home pay. There is no official percentage rule, but the arithmetic below shows how much of a paycheck each plan takes.

Illustration only: the take-home amounts are examples, not averages. Each cell is the one-person USDA plan cost for ages 20–50 (August 2026, +20%) divided by that take-home pay.

Practical ways to keep the bill down for one person:

• Plan meals around what you already have and write a list before you shop, so less food goes to waste.
• Compare unit prices (price per pound or ounce on the shelf tag) rather than package prices, and try store brands.
• Buy perishables in amounts you can use; large packs are only cheaper if you finish them. Freeze bread, meat and leftovers in single portions.
• Cook in batches and plan for leftovers, which is how the USDA plans assume meals are made.
• Watch the categories that moved most. Beef has risen far more than chicken since 2020 in the BLS data above, so the protein mix you choose has a real effect on the total.

SNAP Food Benefits for a Single Person (2026)

If your income qualifies, SNAP (Supplemental Nutrition Assistance Program) can help cover groceries. For the year Oct. 1, 2026 through Sept. 30, 2027, in the 48 contiguous states and the District of Columbia:

• Maximum monthly SNAP benefit, one person: $306
• Gross income limit, one person: $1,729 a month (130% of the poverty line); households must meet other requirements too

The maximum benefit is calculated each year from the cost of the Thrifty plan for a family of four, adjusted down for smaller households. So it doesn’t necessarily cover the full Thrifty plan for a single adult: $306 is about the one-person Thrifty cost for a woman aged 20–50 ($304), but about $77 short of the figure for a man ($383). Income limits are higher in Alaska and Hawaii, and benefit amounts differ outside the 48 states and DC. USDA updates the maximum benefits and income limits at the start of each federal fiscal year on October 1.

SNAP is run by state agencies, so you apply through your state. Eligibility details are on the USDA SNAP eligibility page.

Key Takeaways

1. USDA’s plans put one adult aged 20–50 at $304–$583 a month for groceries (August 2026 costs with USDA’s suggested 20% one-person adjustment), from the Thrifty plan (female) to the Liberal plan (male)
2. The Moderate-cost plan is about $403–$478 a month, or roughly $93–$110 a week
3. The plans assume every meal is cooked at home, so they are a benchmark for a nutritious diet, not a measure of average spending
4. Food-at-home prices were about 32% higher in September 2026 than in January 2020 (BLS CPI); ground beef rose about 75%, while eggs and butter have come down from their 2024–2025 peaks
5. The maximum SNAP benefit for one person is $306 a month from October 1, 2026 (48 states and DC), with a gross income limit of $1,729 a month
