Formula
Cost per serving = price ÷ servings. Cost per gram of protein = cost per serving ÷ protein grams per serving. Lower numbers mean a cheaper protein source.
Example

How to use
- Pull protein grams from the nutrition label — most show 'protein' per serving directly.
- Use the same serving definition across products for a fair comparison.
- Run a few common staples (chicken, eggs, beans, tofu, whey) and bookmark the cheapest per gram.
When it's useful
- Choosing between protein sources at the store.
- Costing meal-prep protein for the week.
- Spotting overpriced 'high-protein' marketing.

Frequently asked
Is this nutrition or diet advice?
No. It's a cost comparison only — it doesn't recommend an intake or diet style.
What's a typical cost per gram of protein?
Cheap staples are often under $0.05/g; specialty protein products can be much higher. Use this calculator to find your own benchmarks.
Do I include cooking loss?
Optional. For meat, raw vs cooked weight changes both protein and price-per-serving slightly — use whichever you actually consume.
Does protein quality matter for this?
Not for cost. This tool compares price; quality and amino-acid profile are separate considerations.
