What this means
Choose your household and plan, then compare an optional spending total.
| Plan | Weekly | Monthly |

Source: USDA September 2026 report. Household totals are WorldLensia calculations from published member costs. Amounts are rounded to cents; small weekly/monthly rounding differences are normal.
Both options recalculate your current inputs. The PDF includes your household, comparison, all four plans and source month. It is created on your device; spending is not uploaded.
How to use the grocery budget calculator
This USDA grocery budget calculator helps you compare a household food-at-home benchmark with your own spending. You can calculate a benchmark without entering any spending. Use it as a weekly or monthly grocery budget calculator for one person, two adults or a family by adjusting the household rows.
Add everyone you buy food for
Enter each person’s age in years and choose the USDA reference category for ages 12 and older. Use the quantity field for people with the same age and reference. For children under 12, the reference selector is disabled because the published child rows do not separate female and male costs.
Choose a plan and spending period
Start with Low-cost, or compare another plan. Select weekly or monthly spending. If your supermarket total contains nonfood items, enter those items separately so they are subtracted once. Changing periods converts amounts already entered using 4.333 weeks per month.
Review the comparison and assumptions
Select Compare my budget. Read the selected benchmark, the difference and the four-plan table. Check the household count, adjustment and data month. An amount above or below a benchmark does not establish whether your diet is suitable or whether you should spend less.
What should you include?
Compare like with like: these plans cover food and snacks prepared at home.
✓ Include
- Food and nonalcoholic beverages for home consumption.
- Fruit, vegetables, grains, dairy and protein foods.
- Pantry ingredients and packaged food bought for home.
- Food purchases across all stores, not just one receipt.
− Keep separate
- Restaurant meals, takeout and delivery charges.
- Toiletries and personal-care items.
- Cleaning supplies and household goods.
- Pet food, alcohol and tobacco.
Use a representative period. A pantry restock, bulk purchase, holiday or trip can make one week look unusually expensive. If you eat many meals elsewhere, the all-meals-at-home benchmark is less directly comparable.
An example, step by step
Suppose your supermarket purchases total $350 for a month, including $40 of toiletries and cleaning supplies.
Your comparable food-only spending is $310 per month. Do not subtract the $40 again or enter unrelated nonfood spending that was never in the $350 total.
If you are one adult aged 30 using the female reference and Low-cost plan, compare the $310 food-only spending with the September benchmark of $331.56: $310 − $331.56 = −$21.56 (6.5% below). This gap is a comparison, not a recommended cut or proof that the budget meets your needs.
Subtract only what is already included: if $350 was food-only to begin with, enter $0 for nonfood. A separate $40 toiletries receipt must not be deducted from that food-only total.
September 2026 household examples
Low-cost benchmarks for the mainland US. Adults are aged 30; the family uses children aged 7 and 10. Each row sums the published weekly and monthly costs separately, then applies the household adjustment.
| Household | Adjustment | Weekly | Monthly |
|---|---|---|---|
| One adult, female reference | +20% | $76.56 | $331.56 |
| Two adults, female + male references | +10% | $150.81 | $653.40 |
| Two adults + children aged 7 and 10 | None | $260.10 | $1,126.90 |
One adult: $276.30 × 1.20 = $331.56 monthly. Two adults: ($276.30 + $317.70) × 1.10 = $653.40. Family: $276.30 + $317.70 + $261.50 + $271.40 = $1,126.90.
Try these presets at the top of the calculator, then replace the example ages and references with your own. These household figures are WorldLensia calculations, not separate USDA estimates of local grocery bills.
Understand the four USDA food plans
USDA publishes four food plans representing food-at-home costs at different spending levels. They are reference market baskets, not four observations of the average American grocery bill. A plan name is not a judgment of a household or a personalized nutrition prescription.
| Food plan | How to interpret it |
|---|---|
| Thrifty | A budget reference using the reevaluated 2021 Thrifty market basket. Its assumptions differ from the other three plans. |
| Low-cost | Another budget-level reference. Selected by default so you can begin with a consistent comparison. |
| Moderate-cost | A higher spending-level reference for the published household groups. |
| Liberal | The highest spending level among these four reference plans. |
The figures will not always increase neatly from Thrifty to Low-cost for every age group. The underlying market baskets and assumptions differ. Do not force the results into a sorted order or treat one plan as a guaranteed minimum needed by every person.
How the USDA grocery budget calculator works
The dataset used here is the September 2026 USDA monthly cost-of-food report, checked on 28 October 2026. We display the actual data month rather than calling it a current local price quote. Check the official source below for newer releases.
Add published member costs → Apply the household-size adjustment → Display weekly and monthly totals
For each plan, we match every member to a published age and reference row, multiply by the quantity and add the values. USDA’s per-person values use a four-person household as their basis. We then apply its suggested adjustment to the entire household total:
| Household size | Adjustment |
|---|---|
| 1 person | Add 20% |
| 2 people | Add 10% |
| 3 people | Add 5% |
| 4 people | No adjustment |
| 5–6 people | Subtract 5% |
| 7 or more people | Subtract 10% |
For example, the published Low-cost monthly member figure for the female adult reference aged 20–50 is $276.30. For a one-person household, $276.30 × 1.20 = $331.56 per month. That household total is our arithmetic from USDA data, not a separate official local estimate.
We sum the published weekly and monthly columns separately, then apply the same adjustment. USDA rounds its source amounts, so multiplying an already rounded weekly result by 4.333 can differ slightly from the displayed monthly result. Optional user-entered spending is converted between periods using 4.333 weeks per month.
Coverage and limits
- The benchmark calculation covers the contiguous 48 states and Washington, DC. Selecting Alaska or Hawaii suppresses the mainland comparison rather than inventing a regional adjustment.
- The tool supports ages 1–110 and up to 30 people. Infants under 1 are not covered by the published rows used here.
- The September 2026 USDA web tables use ages 14–19 and 20–50 for all four plans. This calculator follows those published age bands.
- No adjustment is made for individual dietary requirements, medical needs, local retail prices, food waste or meals eaten away from home.
- This calculator does not assess SNAP eligibility, benefit amounts or whether a household has enough income for its needs.
How to read your grocery spending comparison
What this benchmark can tell you
The estimated cost of a USDA reference food basket for your selected household and plan, and how your recorded food-only spending compares with it.
What it cannot tell you
Your local checkout price, the average bill of similar families, whether a diet is adequate, a personalized savings target, or SNAP eligibility and benefits.
Your food-only spending is the supermarket total minus the nonfood items you included in that total. Your benchmark is the household estimate for the selected plan. The dollar difference and percentage show the gap relative to that benchmark, not a required spending reduction.
If you spend more, first check whether your total includes restaurant meals, purchases for guests, delivery fees or nonfood goods. Consider whether the period includes a large stock-up. If you spend less, check whether you left out another store, used existing pantry food or ate meals elsewhere. A low total does not prove a diet is adequate.
Use the result to choose one practical next step: track food-only receipts for a month, plan meals from food you already have, or compare the unit prices of purchases you regularly make. Keep medical or dietary needs central to any budget decision.
Common questions
Is this an average grocery bill?
No. USDA food plans are cost benchmarks for defined food-at-home market baskets. They are not a survey average of what households spend. Our household totals apply the published member costs and household-size adjustment.
Can I use this grocery budget calculator for one person?
Yes. Add one adult, enter their age and choose a USDA reference category. The calculator adds the suggested 20% one-person adjustment. Optional spending lets you compare your own food-only total with that benchmark.
Does this include restaurants or takeout?
No. Keep restaurant meals, takeout and delivery charges separate. The underlying benchmark assumes meals and snacks are prepared at home. The tool does not proportionally reduce the benchmark when you eat out.
What if I live in Alaska or Hawaii?
Select Alaska or Hawaii to suppress the mainland benchmark. You can still work out food-only spending. USDA publishes separate regional Thrifty information, but the regional figures shown for a reference family should not be applied as if they covered every household composition.
Why is a USDA reference category required for older children and adults?
The published tables separate female and male reference groups from age 12 onward. These are source categories for estimating a benchmark, not personalized energy requirements. For children under 12, the calculator uses the common child row.
How often are the figures updated?
USDA publishes monthly reports. This page currently uses September 2026 data, with the source month visible beside the calculator. WorldLensia updates the bundled data after checking a new release; this page does not fetch live food prices.
Are my spending amounts saved or uploaded?
The calculator processes entries in your browser and does not upload or intentionally store the entered amounts. Reloading the page resets the calculator. The wider site may use cookies or analytics described in our privacy policy; calculator input values are not sent by this tool.
How do I print or save my results?
Select Download summary PDF for a file containing the current household, spending comparison, all four plans and source month. Or select Print summary / Save as PDF to open your browser’s print dialog. Both recalculate valid inputs first. Choose a printer or Save as PDF in that dialog, or cancel to return.
