What this calculator is
Protein costs very different amounts depending on the source. A tub of powder, a dozen eggs, a can of tuna and a steak can all supply protein at prices that vary several-fold per gram. This calculator takes the total grams of protein in a package and its price and returns grams of protein per dollar and dollars per gram, making unit prices easy to compare. Cost per gram of protein is only one factor. Protein quality, other nutrients, calories, taste, preparation time and dietary needs also matter, and package labels list protein per serving, so you must multiply by the number of servings. Use the tool to compare similar options, not as a nutritional recommendation.
When to use / who it helps
- You are comparing protein powders, bars or whole foods on cost.
- You are budgeting a high-protein diet.
- You are deciding between package sizes.
- You want to know the cheapest protein sources at your local store.
- You are checking whether a sale price is actually better value.
How to use
Steps
- Find the grams of protein per serving on the label and multiply by the servings per package.
- Enter the total protein grams.
- Enter the total price of the package.
- Read grams per dollar; higher is better value.
- Read dollars per gram for a unit price.
- Repeat for each product and compare.
How to interpret results
- A higher grams-per-dollar figure means more protein for your money.
- Dollars per gram is the inverse; lower is cheaper.
- The calculation ignores protein quality, calories and other nutrients.
- Compare like with like, such as ready-to-eat items with ready-to-eat items.
- Prices change by store and week, so recheck before relying on a ranking.
Common mistakes & gotchas
- Entering protein per serving instead of per package.
- Ignoring the price of the whole package.
- Comparing a product's price with another measured by a different serving size.
- Choosing only by cost while ignoring dietary needs.
- Forgetting that cooking changes weight, so cooked and raw values differ.
Worked example
Worked example — 25 g of protein for $3.50
- Grams per dollar: 25 ÷ 3.50 ≈ 7.14.
- Dollars per gram: 3.50 ÷ 25 = $0.14.
- A 2 lb tub with 1,000 g of protein costing $30 gives 1,000 ÷ 30 = 33.3 g per dollar.
- The tub is much cheaper per gram, but it may not suit every meal or diet.
Result: 25 g for $3.50 is about 7.1 g of protein per dollar, or $0.14 per gram.

Frequently asked questions
How do I calculate protein per dollar?
Divide total protein grams by the price.
Is cheaper protein always better?
Not necessarily. Quality, nutrients, calories and preferences also matter.
Where do I find protein grams?
On the nutrition label, per serving. Multiply by servings per container.
How much protein do I need?
Needs vary by age, size and activity. A dietitian or doctor can advise you.
Do raw and cooked weights differ?
Yes. Cooking changes weight, so compare labels carefully.
Can I compare protein powder with food?
Yes, using the same calculation, but remember differences in nutrients and satiety.
