How USDA Food Plans Work

The USDA publishes monthly food cost reports with four spending tiers. These are the closest thing to an official answer for how much you should spend on groceries.

What are the four USDA food plans?

The USDA Center for Nutrition Policy and Promotion publishes four food plans: Thrifty, Low-Cost, Moderate, and Liberal. Each represents a different level of spending that still meets nutritional guidelines. The Thrifty Plan is the basis for SNAP (food stamp) benefits. The other three plans reflect progressively higher spending with more variety and convenience foods.

What affects your grocery spending?

Three factors matter most: household size (larger families get bulk discounts but need more food), how many meals you cook at home vs. eat out, and food waste. The average household throws away $728 per person per year in wasted food. Reducing waste is often the fastest way to cut your grocery bill without eating less or buying cheaper food.

The hidden cost of food waste

According to the EPA, the average American wastes about $728 per person per year on food they buy and never eat. For a family of four, that's nearly $3,000 going straight into the trash. Planning meals around what you already have, using leftovers strategically, and shopping with a list that accounts for your pantry are the most effective ways to reduce this waste.

How to actually stay within your grocery budget

Knowing your target number is the easy part. Hitting it requires three habits: plan meals around what's already in your kitchen (not the other way around), buy what's on sale and then build meals around it, and cook enough for leftovers so you're not planning 21 individual meals every week. An AI meal planner can automate all three of these strategies.

Frequently Asked Questions

How much should a family of 4 spend on groceries per month?
According to USDA food plans (2025), a family of four on the Moderate plan spends approximately $1,250-$1,400 per month on groceries. The Thrifty plan brings this down to around $900-$1,000, while the Liberal plan runs $1,500-$1,700. These figures assume all meals are prepared at home.
What percentage of income should go to groceries?
Financial experts recommend spending 10-15% of your take-home pay on groceries. This fits into the 50/30/20 budget rule where groceries are part of the 50% allocated to needs. If you're spending more than 15% on groceries alone, you may have budget leaks from food waste, impulse purchases, or eating out.
How much does a single person spend on groceries per month?
A single adult (ages 19-50) spends between $268-$566 per month depending on the USDA plan level, with an additional 20% adjustment for single-person households who can't buy in bulk as efficiently. The national average is approximately $207 per person per month.
How does the USDA calculate food costs?
The USDA Center for Nutrition Policy and Promotion uses national food price data, dietary guidelines, and consumption surveys to calculate the cost of a nutritious diet at four spending levels. They update these figures monthly and adjust for age, sex, and household size.
Why is my grocery bill so high?
The three biggest reasons: food waste ($728/person/year according to the EPA), shopping without a plan (impulse purchases account for up to 62% of grocery spending), and delivery/takeout replacing home cooking. A single delivery order costs $15-25+ compared to $4-6 for a home-cooked meal.
How can I spend less on groceries without eating worse?
Plan meals around what you already have in your kitchen, buy what's on sale and adapt your recipes, cook larger batches for leftovers, and shop with a list that accounts for your pantry inventory. These strategies reduce waste and duplicate purchases without sacrificing nutrition or variety.
Does this calculator work for non-US households?
This calculator uses USDA data which reflects US food prices. The age-based ratios and household size adjustments are useful directionally for other countries, but the dollar amounts may not match local food costs. Adjust results based on your country's cost of living relative to the US.
How accurate is a grocery budget calculator?
USDA food plan data is the gold standard for US grocery budgeting, but it assumes all meals are home-cooked and doesn't account for regional price differences (Hawaii costs 35% more than average), dietary restrictions, or organic preferences. Use the results as a benchmark and adjust based on your specific situation.
