Protein per dollar: useful arithmetic with clear limits

Use the meal you will actually buy

Begin with a verified price for the selected basket. Include delivery, mandatory fees, and paid choices. Decide how to allocate those costs across meals and state that method. If you use a promotional price, keep it separate from the normal-price comparison.

Next record each exact meal’s published protein figure and serving basis. A ratio built from an advertised starting price and a different premium recipe is not a comparison of a purchasable meal.

An illustrative calculation

Suppose a hypothetical meal costs $12 after your stated allocation of delivery and contains a reported 30 grams of protein per serving. That is 2.5 grams per dollar, or $0.40 per reported gram. These numbers are invented to explain the calculation; they are not prices or nutrition values for any provider.

For another hypothetical meal costing $10 with 20 reported grams, the ratio is 2 grams per dollar. The first ratio is higher, but that fact alone does not establish better value. The meals may differ in size, ingredients, effort, preferences, and other nutritional characteristics.

Know what the ratio leaves out

Protein per dollar does not measure how well a meal fits your requirements, whether it contains allergens, how much food you will waste, or how much time you want to spend cooking. It also does not measure a health outcome. A single ranking can hide those differences.

If you do not eat the whole labeled serving, be careful. Dividing cost by the full published protein amount assumes you use that food. If part is discarded, the purchased ratio and the used-food estimate are different calculations.

Check how shipping changes the calculation

Suppose a hypothetical two-meal order costs $20 for the food plus $6 shipping. If you allocate shipping equally, each meal carries $3 of delivery cost. A ratio based only on the $10 food price answers a different question from a ratio based on the $13 delivered allocation. Neither number should appear without its method. If the meals have different prices, you could choose another reasonable allocation, but state it and apply it consistently.

Discounts require similar care. A first-order credit may make a trial inexpensive while leaving the ongoing basket unchanged. Keep separate columns for trial and regular delivered totals. Avoid combining a discounted price from one service with an ongoing price from another unless your purpose is specifically to compare first purchases. Finally, record whether the whole basket is useful. A favorable ratio does not compensate for ordering meals you will not eat, and it cannot determine how much protein you personally need.

Use it as one column

Keep the ratio alongside the full basket cost, preparation effort, serving basis, and your preference notes. It is most useful for comparing otherwise plausible candidates, not for selecting a diet from scratch.

• Verify exact current prices and recipe versions.
• State how shipping and discounts are allocated.
• Use a consistent serving basis.
• Label illustrative or estimated inputs clearly.
• Retain the whole-meal context when making the decision.
