Cost only. This calculator cannot assess safety, effectiveness, absorption or personal dosing.

How to use this calculator

Enter the price of one bottle and its allocated checkout charges. Discounts are dollar amounts, not percentages. Read the package for total capsule, tablet or gummy count and the number of those units in one labeled serving. The daily-use input is a budgeting assumption you supply, not a dose recommendation.

Formula: net bottle cost = price + charges − discount; servings = units ÷ units per serving; cost per serving = net cost ÷ servings. Supply days = servings ÷ assumed daily servings. Thirty-day consumption cost = cost per serving × daily servings × 30.

Illustrative example: a $24 bottle with $4 charges and 120 capsules at two capsules per serving contains 60 servings. Its $28 net cost divided by 60 is $0.4667 per serving. At one serving a day, supply is 60 days and the 30-day consumption cost is $14. This is allocated consumption cost, not necessarily the cash paid this month.

Limits

The calculator cannot assess safety, absorption, effectiveness, expiry or whether two products are medically interchangeable. Compare matching labeled quantities first. Fractional counts are allowed for powders measured by weight, but use consistent units. Zero denominators and discounts larger than the checkout cost are rejected. Calculations stay in your browser.
