What’s a good price for protein bars?

How to land in the good-price band

Bars are sold by the box and eaten one at a time, so cost per bar is what actually hits your wallet — and it swings 3× between brands for a similar 15–20 g of protein.

• •Divide the box price by the bar count. Premium bars run $2.00–2.25 each; solid mainstream options land near $0.70–1.20 — for protein that does the same job.
• •Check grams of protein per bar, then cost per bar. A cheap bar with 5 g of protein is a candy bar; the honest comparison is cost per bar at a similar protein load (15 g+).
• •The big-count box + Subscribe & Save is the floor. Per-bar cost falls with box size, and bars keep for months — buy 12s and 24s, not singles.
• •A single bar at the checkout is the worst price in the category — often 2–3× the per-bar cost of the same bar in a box.
