Shopping for one sounds like it should be cheap. In practice it’s often the opposite. Packages are sized for families, recipes make four servings, and half a bag of spinach ends up in the trash. Per person, a household of one usually spends more on food than a family does.
Here’s a realistic grocery budget for one person based on USDA figures, whether $200 a month is enough, and a priced starter week that keeps the cost down without wasting food.
Grocery Budget for One Person: The USDA Numbers
USDA publishes a monthly food budget for each age group. Using its August 2026 figures for the Low-Cost and Moderate-Cost plans, with USDA’s 20% adjustment for people who live alone, one adult cooking all their meals at home spends roughly:
| Person | Low-Cost plan | Moderate-Cost plan |
|---|---|---|
| Woman, 19 to 50 | About $76 a week ($330 a month) | About $93 a week ($403 a month) |
| Man, 19 to 50 | About $88 a week ($380 a month) | About $110 a week ($478 a month) |
| Woman, 51 to 70 | About $74 a week ($322 a month) | About $92 a week ($397 a month) |
| Man, 51 to 70 | About $83 a week ($359 a month) | About $104 a week ($450 a month) |
Source: USDA Official Food Plans, Cost of Food reports, U.S. average for August 2026. We added USDA’s recommended 20% for a one-person household and rounded. Monthly figures use 4.33 weeks a month.
The extra 20% is USDA’s way of saying what most people already know: it costs more per person to shop for one. USDA’s leaner Thrifty plan comes in lower, and that’s the level most of the tips below aim for. If you’re budgeting for a whole household, see how much a family of 4 should spend on groceries.
Is $200 a Month Enough?
For one person, $200 a month works out to about $46 a week. That’s well below USDA’s Low-Cost plan, but it’s doable if you cook almost everything yourself and build meals around cheap staples like rice, beans, lentils, eggs, oats and frozen vegetables.
A $25 or $30 week is tighter still. It works best as a starting point: the first week you stock up on staples, and after that you mostly replace eggs, bread, milk and produce, which brings the following weeks down.
A $31 Starter Week for One
Prices are from Walmart’s and ALDI’s websites for stores in Columbus, Ohio, checked in October 2026. Ohio’s grocery prices are within about 1% of the national average, so you may pay more or less depending on where you live, and prices change often. Here’s how we price our recipes.
This list covers a week of breakfasts, lunches and dinners for one adult. It assumes you already have oil, salt and a few basic spices. Each item is from whichever store was cheaper.
| Item | Amount | Price |
|---|---|---|
| Large eggs | 1 dozen | $1.66 (ALDI) |
| Black beans | 2 cans (15 ounces) | $1.70 (ALDI) |
| Dried lentils | 1 pound | $1.92 (Walmart) |
| Long-grain rice | 3-pound bag | $2.65 (ALDI) |
| Old-fashioned oats | 42-ounce canister | $3.99 (ALDI) |
| Peanut butter | 16 ounces | $1.49 (ALDI) |
| Bread | 1 loaf | $1.45 (ALDI) |
| Bananas | 6 | $1.02 (Walmart) |
| Frozen mixed vegetables | 2 bags (12 ounces) | $1.96 |
| Yellow onions | 3-pound bag | $2.39 (ALDI) |
| Carrots | 2-pound bag | $1.99 (ALDI) |
| Crushed tomatoes | 1 can (28 ounces) | $1.55 (ALDI) |
| Milk | 1 gallon | $2.43 |
| Shredded cheddar | 8 ounces | $1.97 (Walmart) |
| Flour tortillas | 10 count | $1.95 (ALDI) |
| Spaghetti | 1 pound | $1.24 (Walmart) |
| Total | $31.36 |
The rice, oats, peanut butter, onions and lentils will last well past the first week. The second week, you’d only need eggs, bread, bananas, milk, beans, tortillas, crushed tomatoes and frozen vegetables again, about $14 at these prices.
What You’ll Eat
- Breakfast: oatmeal with banana and peanut butter, or eggs and toast. Try peanut butter banana overnight oats to make it ahead.
- Lunch: bean and cheese quesadillas, peanut butter sandwiches or a bowl of leftover soup.
- Dinner: a pot of vegetable lentil soup (freeze half), spaghetti with marinara, rice and beans, veggie fried rice and an egg scramble bowl.

Cooking for One Without Wasting Food
- Cook once, freeze half. Soups, chili and casseroles freeze well in single portions. A big pot becomes four or five future dinners.
- Buy loose produce. Pick up two carrots or one onion instead of a bag you won’t finish, unless the bag is cheaper and keeps for weeks, like onions and carrots usually do.
- Lean on the freezer. Frozen vegetables, bread and shredded cheese keep for months. Take out only what you need.
- Plan meals that share ingredients. If you buy cilantro for tacos, plan rice bowls later in the week so the rest gets used.
- Halve recipes that don’t freeze. Salads and egg dishes are easy to cut down. Our cheap meals for two are already sized small.
- Keep a use-it-up night. Once a week, make fried rice, a frittata or quesadillas from whatever’s left. More ideas are in how to reduce food waste at home.
Grocery Budget Questions
How much should one person spend on groceries a month?
On USDA’s Low-Cost plan, about $320 to $380 a month for an adult who cooks all their meals at home, depending on age and sex. Careful shoppers who cook from scratch can spend less.
Is $50 a week enough for one person?
Yes, if you cook most of your meals. Our starter week came to about $31, which leaves room for more fresh produce, some meat or a few treats.
Is $30 a week enough for one person?
It’s tight but possible, especially after the first week, once staples like rice, oats and peanut butter are already in the cupboard.
What’s the cheapest way to eat as one person?
Cook big batches of soups, beans and rice dishes, freeze single portions, and build meals around eggs, oats, lentils, beans and frozen vegetables.
