Groceries are the third-largest household expense after housing and transportation. Here’s what one person actually spends — and what the USDA says you should budget.
USDA Food Plans (Single Adult, 2025-2026)
The USDA publishes four food-cost plans updated monthly:
| USDA Plan | Monthly Cost (Male 19-50) | Monthly Cost (Female 19-50) | Average |
|---|---|---|---|
| Thrifty | $250 | $215 | $233 |
| Low-cost | $330 | $290 | $310 |
| Moderate-cost | $405 | $355 | $380 |
| Liberal | $510 | $430 | $470 |
The moderate-cost plan is the most realistic benchmark for regular grocery shopping without extreme budgeting.
