About
USDA Food Plans (2025): Thrifty: $260-330 per adult/mo. Low cost: $300-400. Moderate: $370-470. Liberal: $450-580. Kids 4-12: ~80% of adult. Teens: 100-110%. Adjust for region: NYC/CA add 15-30%.
The USDA's four official food plans are the reference grocery budgets used to set SNAP benefits, military BAS and divorce-court support calculations. The Thrifty Plan was rebased in 2021 (the first reset in 45 years) and is now indexed monthly to the Consumer Price Index for Food at Home. Through 2025 and into early 2026 USDA food-at-home CPI ran around 2-3% above 2024, so the 2025 reference dollars above are roughly current. The plans assume all meals are cooked at home from scratch, with realistic shrinkage and waste. They do not include restaurant meals, alcohol, paper goods, pet food, or cleaning supplies, all of which household-budgeting apps often lump under "groceries". If your tracked grocery line includes those, expect to land 10-20% above the plan.
Formula
Frequently asked questions
How accurate is the Grocery Budget Calculator?
It applies the standard formula. Accuracy is limited only by your input precision. For decisions with material consequences (taxes, medical, legal, structural), use the result as a starting point and verify with a qualified professional in the relevant field.
Is the Grocery Budget Calculator free to use?
Yes. 100% free, no signup, no payment, no API key. The site is funded by display ads around the tool but not inside the calculation flow.
Are my inputs saved anywhere?
No. All inputs stay in your browser tab. Closing the tab discards them. The site uses Google Analytics for traffic measurement (anonymized) but the analytics never see what you type into the form.
Can I use the Grocery Budget Calculator on my phone?
Yes. The tool is responsive and tested on iOS Safari, Android Chrome, and major desktop browsers. Touch targets meet Apple's 44pt and Google's 48dp minimum.
Does the Grocery Budget Calculator work offline?
Yes. Once the page has loaded, it works without internet. The calculation runs in JavaScript on your device.
How do I report a bug or suggest improvement to the Grocery Budget Calculator?
Email hi@3tej.com with the URL of this page and a description of what you saw vs expected. We typically respond within 72 hours.
Can I share results from the Grocery Budget Calculator?
Take a screenshot or copy the output. The page doesn't generate shareable URLs for specific calculations - inputs stay in your browser only.
Why are the results different from another grocery budget tool?
Most likely: different formula assumptions, different default values, different rounding rules, or different applicable rates. Check the methodology if both tools document it. Both can be valid for different scenarios.
Is the Grocery Budget Calculator accurate?
The Grocery Budget Calculator applies the standard formula for grocery budget. Accuracy is limited only by your input precision. For decisions with material consequences, use the result as a starting point and verify with a qualified professional or the relevant official source.
Is the Grocery Budget Calculator free?
Yes. 100% free, no signup, no payment, no API key. The site is funded by display ads that appear around the tool but not inside the calculation flow.
Are my inputs saved?
No. Inputs stay in your browser tab. Closing the tab discards them. The site uses Google Analytics for traffic measurement (anonymized) but does not see what you type into the form.
Should I budget separately for dining out and takeout?
Yes. The USDA plans cover food at home only. BLS Consumer Expenditure Survey data for 2024 shows the average US household spent about 46% of total food dollars on food away from home, so a realistic full-food budget is the USDA grocery number plus a separate restaurant/takeout line that is often half the grocery line again. Mixing the two breaks regional comparisons and makes the calculator output look "too low" for households that order out frequently.
How do I adjust the USDA plans for a vegetarian or gluten-free household?
The Thrifty and Low-cost plans assume a meat-heavy market basket. Swapping for legumes, lentils, eggs and tofu usually cuts the per-adult cost by 10-15% at the Low-cost tier. Gluten-free baking flours and breads typically run 2-3x conventional, adding 15-25% to a moderate-tier plan. Specialty diets (keto, kosher, halal-certified) similarly skew the basket and need a custom line item, not a flat multiplier.
How to use the Grocery Budget Calculator
The Grocery Budget Calculator is a browser-based tool that runs entirely on your device. Inputs you enter never reach a server - all calculations happen client-side in JavaScript. This means:
- Privacy: nothing is logged, sent, or stored by 3Tej. Inputs disappear when you close the tab.
- Speed: results update as you type. No network round trip.
- Offline use: once the page is cached, it works without internet.
- No signup: no account, no email, no rate limits.
Step by step
- Enter your inputs in the form above. Each field is labeled with its unit (currency, percent, kg, etc.) and the expected range.
- Read the result as it updates. The number reflects the formula commonly accepted in Grocery Budget-related calculations.
- Adjust to see sensitivity: change one input at a time and watch how the output moves. This is the fastest way to understand which variable matters most.
- Copy or screenshot the result for later reference. The page state persists for the session if your browser allows it.
When you would use this
- Quick estimates: when you need a number now and don't want to open a spreadsheet.
- Sensitivity analysis: testing how a result changes as inputs vary, before committing to a real-world decision.
- Comparison: running the same calculation with different inputs to compare options side by side.
- Learning: building intuition for how the underlying math behaves.
- Documentation: capturing a snapshot of inputs and outputs at a point in time.
