About the Grocery Budget Planner

Estimates a monthly and annual grocery budget from household size (adults and children) and a chosen USDA Food Plan spending level — Thrifty, Low-Cost, Moderate-Cost, or Liberal — using USDA's own published per-person cost figures and household-size adjustment.

How to use it
  1. Enter the number of adults and children in the household.
  2. Choose a USDA Food Plan spending level.
  3. Read the estimated monthly and annual grocery budget.
Formula
Monthly cost = (adults × per-adult monthly cost + children × per-child monthly cost) × household-size adjustment factor. Adjustment: 1-person +20%, 2-person +10%, 3-person +5%, 4-person no adjustment, 5-6 person −5%, 7+ person −10%.
Worked example

2 adults + 2 children on the Moderate-Cost Plan: (2 × $356.85 + 2 × $316.75) × 1.00 = $1,347.20/month, or $16,166.40/year.

Interpreting your result

USDA republishes these Food Plan costs monthly using CPI-U data, so current-month figures will drift slightly. Thrifty Plan figures are U.S. Average, January 2025 data; Low-Cost/Moderate/Liberal figures are U.S. Average, December 2025 data.

Recommendations
  • The Thrifty Plan is USDA's baseline for SNAP benefit calculations — restrictive but nutritionally complete.
  • A smaller household pays a real per-person premium under USDA's own methodology.
  • These figures assume every meal is prepared and eaten at home.
Frequently asked questions
