How to Calculate the Real Cost Per Supplement Serving

Cost per capsule is not cost per serving

Take the final delivered price, including shipping and required charges, and divide by capsule count. That yields cost per capsule. A serving may contain more than one capsule, so this number cannot automatically be marketed as the daily cost. Use the current directions for that conversion.

Calculate a fair comparison

First record actual checkout total. Second note bottles and capsules per bottle. Third obtain the exact number of capsules per serving and servings per day from the current label. Only then divide the paid price by total servings. Keep any taxes, handling and auto-ship obligations in the model.

Why the cheapest bundle can be the wrong value

A bulk package may have a lower per-bottle price, but unused bottles, an uncertain return process or a change in medical advice can make a larger order expensive. Value also involves label transparency, independent evidence and the product’s suitability for the individual.

Example without inventing a dose

The ProstaPeak images say 60 capsules per bottle, and the seller advertises several bundle prices. Because a complete back-label direction was not verified, we can report the seller’s per-bottle offers but avoid presenting a precise evidence-based per-day dose or cost.

Do not let an arithmetic shortcut distort science

A low daily price is not proof of a clinically effective amount. Ingredient amount and chemical formulation are needed to compare a supplement with published research. Treat price analysis and efficacy analysis as separate tasks.
