How to calculate cost per serving
Cost per serving = total container cost ÷ servings per container. Total cost includes the container price plus any shipping and tax you allocate to it. Use the actual price you plan to pay after discounts, and compare the same purchase terms.
How to compare the cost of equal amounts of protein
Cost per 25 g of protein = total container cost × 25 ÷ (servings per container × protein grams per serving). A scoop's weight is not the same as its protein content. Use the grams of protein on the nutrition panel, not the serving weight or net tub weight. The 25 g figure is a comparison unit, not a recommended serving or daily intake.
A worked example
These are hypothetical prices and labels, not current HerbaGrove offers. Product A costs $60 for 30 servings with 25 g of protein each: $2.00 per serving and $2.00 per 25 g of protein. Product B costs $45 for 15 servings with 20 g each: $3.00 per serving and $3.75 per 25 g of protein. Both examples exclude shipping and tax. The lower tub price does not necessarily give the lower cost per serving.

Value includes more than price
A lower cost per gram does not establish better quality, taste or suitability. Compare the complete ingredient list, allergens, protein source, mixing directions and purchase terms. Whey is milk-derived. If you are comparing protein sources, see our whey vs plant protein guide.
Frequently asked questions
Should I enter scoop weight or protein grams?
Enter protein grams per labeled serving. A 30 g scoop may contain a different amount of protein; scoop weight also includes other ingredients.
Can I compare different serving sizes?
Yes. Cost per 25 g of protein standardizes the protein amount even when the products have different serving sizes. It does not compare taste, ingredients or suitability.
How should I include shipping or a subscription discount?
Use the price and shipping you will actually pay. For a multi-item order, allocate shipping consistently between containers. Compare subscription prices with subscription prices, or one-time prices with one-time prices, and check renewal terms.
Does the calculator know current product prices?
No. You enter current prices and label details. Results are estimates based only on those inputs, rounded to two decimal places. No price or nutrition data is fetched automatically.
