Grocery Budget Calculator
Estimate your monthly grocery spending and compare against USDA food plan benchmarks.
Food is typically the third-largest expense after housing and transportation, yet most people have no idea how much they actually spend. The USDA publishes four official food cost plans — Thrifty, Low-Cost, Moderate, and Liberal — that serve as benchmarks for a nutritious diet at different spending levels. This calculator estimates your total food spending and compares it against these benchmarks, helping you find the right balance between eating well and spending wisely.
Your total food spending: $850/month ($425 per person). Above the USDA Moderate plan — consider if you're getting proportional value.

How to use this calculator
Number of people — How many people you're feeding. Per-person costs decrease slightly with more people due to bulk cooking and shared staples.
Weekly grocery spend per person — Your average weekly grocery spending per person. Include all food purchased at grocery stores — not eating out.
Monthly eating out — Total monthly spending on restaurants, takeout, delivery, and coffee shops. This is separate from groceries and often the easiest category to cut.
Real-world examples
Family of 4, moderate spending
4 people × $75/week + $300 eating out = $1,599/month total. USDA Moderate for 4 people: ~$1,687. This family is right on track with the moderate benchmark.
Single professional, high eating out
1 person × $80/week groceries + $400 eating out = $746/month. The eating out alone exceeds USDA Thrifty ($274). Cutting eating out by 50% saves $200/month.
Couple, thrifty plan
2 people × $60/week + $100 eating out = $620/month. USDA Thrifty for 2: ~$549. Slightly above thrifty but well within a healthy, affordable range.

- Eating out costs are separate from USDA grocery benchmarks.
- Dietary restrictions, organic preferences, and local prices can significantly affect actual costs.
Frequently asked questions
What does USDA 'thrifty plan' mean?
The USDA publishes four food cost plans: Thrifty, Low-Cost, Moderate-Cost, and Liberal. The Thrifty plan represents the minimum cost for a nutritious diet and is used to set SNAP benefits.
How can I reduce my grocery bill?
Meal planning, buying in bulk, choosing store brands, reducing food waste, and shopping with a list can cut 20–30% off your grocery bill.
Is eating out always more expensive?
Generally yes — eating out costs 3–5x more per meal than cooking. But some strategies (lunch specials, meal prep services) can narrow the gap. The key is being intentional rather than defaulting to takeout.
How much should I spend on food total?
The USDA Moderate plan is a good target for most people. Financial advisors typically recommend 10–15% of take-home pay for all food (groceries + eating out).
