What is protein cost efficiency comparison?

When buying protein supplements for muscle gain or weight loss, it's hard to know if they're actually cheaper than whole foods like chicken, eggs, or tofu. Calculating the cost per gram of protein gives you an objective way to compare your options.

For example, 500g of chicken breast at $6 (23g protein/100g) gives 115g of protein — about $0.052/g. A 1kg tub of whey at $35 (80g protein/100g) gives 800g of protein — about $0.044/g. The raw price alone is misleading; you need to factor in protein density.

Frequently Asked Questions

Is protein powder always the cheapest option?

No. Budget powders with low protein content can cost more per gram than chicken breast. Always compare using cost per gram of protein, not the sticker price.

Are there other factors beyond cost?

Yes — digestibility, amino acid profile, and convenience all matter. Cost efficiency is one factor; consider your goals and lifestyle too.
