Eating enough protein doesn't have to mean expensive food. Here is the US government's own benchmark for a low-cost, nutritious diet, and the protein in pantry and freezer staples.

The USDA benchmark

USDA publishes four food plans at increasing cost — Thrifty, Low-Cost, Moderate-Cost and Liberal — updated monthly for inflation. It describes the Thrifty plan as a nutritious, practical, cost-effective diet[1].

US-average monthly costs for September 2026: a woman aged 20–50, $253.90 a month (as reported by USDA Food and Nutrition Service, September 2026; checked November 2, 2026 — may have changed)[2]; a man aged 20–50, $319.00 a month (as reported by USDA Food and Nutrition Service, September 2026; checked November 2, 2026 — may have changed)[2]; a reference family of four, $1,024.00 a month (as reported by USDA Food and Nutrition Service, September 2026; checked November 2, 2026 — may have changed)[2].

The plan assumes every meal and snack is made at home. Per-person costs are for a four-person household; USDA says to add 20% for one person, 10% for two and 5% for three[2].

Comparing prices at your store

Prices vary too much by store and region to list here. To compare, divide the price by the grams of protein per package (from the nutrition label) — that gives you cost per gram of protein, which is fairer than cost per package.

In Canada

We haven't yet sourced a Canadian national equivalent of the Thrifty Food Plan, so this page doesn't give Canadian costs. The protein values above from Health Canada's food tables apply in both countries[7].
