About This Tool
The Protein Cost Calculator tells you exactly how much you're paying per gram of protein for any food — the most useful number when comparing protein sources across your grocery options. Enter the package price and nutrition label data, and the calculator does the rest.
Who it's for: Anyone trying to hit daily protein targets without overspending — whether you're building muscle, managing weight, or just trying to make a $50 grocery budget go further. It's also useful for comparing expensive specialty products against budget staples.
How to read the results: Under $0.05/g of protein is excellent value — think eggs, dried lentils, canned tuna. $0.05–$0.10/g is good (chicken thighs, Greek yogurt, cottage cheese). Over $0.15/g is worth questioning; a more affordable source usually exists. The reference table below shows common budget protein sources as a benchmark.
